99-701: Following the establishment of the short-lived American-British-Dutch-Australian military command (ABDACOM) in January 1942, the governments of Australia , the Netherlands and New Zealand began to push Winston Churchill for an inter-governmental war council based in Washington D.C. The Far Eastern Council was established in London on February 9, with a corresponding staff council in Washington. However

198-699: A German aircraft, carrying a staff officer with the Luftwaffe plans for an offensive through central Belgium to the North Sea, force-landed near Maasmechelen (Mechelen) in Belgium. The documents were captured but Allied intelligence doubted that they were genuine. In the full moon period in April 1940, another Allied alert was called for a possible attack on the Low Countries or Holland, an offensive through

297-632: A German attack in the centre of the French front. After the transfer from the strategic reserve of the Seventh Army to the 1st Army Group, seven divisions remained behind the Second and Ninth armies and more could be moved from behind the Maginot Line. All but one division were either side of the junction of the two armies, GQG being more concerned about a possible German attack past the north end of

396-515: A German force consisting of 43 divisions (32 of them reserves) and no tanks. The French advanced until they met the thin and undermanned Siegfried Line . On 17 September, Gamelin gave the order to withdraw French troops to their starting positions; the last of them left Germany on 17 September, the day of the Soviet invasion of Poland . Following the Saar Offensive, a period of inaction called

495-778: A German invasion of the Netherlands but not Belgium, by changing the deployment area to be reached by the Seventh Army; the Escaut plan would only be followed if the Germans forestalled the French move into Belgium. In the winter of 1939–40, the Belgian consul-general in Cologne had anticipated the angle of advance that Manstein was planning. Through intelligence reports, the Belgians deduced that German forces were concentrating along

594-542: A command which included Australia and New Guinea in addition to Japanese-held areas. The rest of the geographic area of the Pacific Theater of Operations remained under the Pacific Ocean Areas command, led by Commander-in-Chief Admiral Chester Nimitz of the U.S. Navy . The inter-governmental Pacific War Council was established in Washington on 1 April, but remained largely ineffectual due to

693-512: A concentration of forces in a position impossible to adequately resupply, along routes that could be cut easily by the French. If the Allies did not react as expected, the German offensive could end in catastrophe. Their objections were ignored and Halder argued that, as Germany's strategic position seemed hopeless anyway, even the slightest chance of decisive victory should be grasped. Shortly before

792-727: A council which was responsible for higher direction of the Pacific War; the London Council (Far East Council) was purely advisory and subordinate . Roosevelt wanted to retain the current arrangements for British-American collaboration, and suggested that where the interests of the three countries (Australia, the Dutch East Indies and New Zealand) were involved they could attend meetings of the Combined Chiefs of Staff in Washington (CCOS) and give their views on

891-580: A determined stand on the Somme and Aisne rivers but were defeated by the German combination of air superiority and armoured mobility. Italy entered the war on the German side on 10 June 1940 and began the Italian invasion of France . German armies outflanked the Maginot Line and pushed deep into France, occupying Paris unopposed on 14 June. After the flight of the French government and the collapse of

990-542: A heavy tank like the French Char B1 ; French tanks were better designs, more numerous, with superior armour and armament but slower and with inferior mechanical reliability than the German designs. Although the German Army was outnumbered in artillery and tanks, it possessed some advantages over its opponents. The newer German Panzers had a crew of five: commander, gunner, loader, driver, and mechanic. Having

1089-666: A huge, but thinly spread force, covering an area from Burma in the west, to Dutch New Guinea and the Commonwealth of the Philippines in the east. Other areas, including the British Raj and the Territory of Hawaii , remained officially under separate commands, and in practice General Douglas MacArthur was in complete control of Allied forces in the Philippines. At Wavell's insistence, North West Australia (see map)

1188-529: A long war in the west. Hitler ordered a conquest of the Low Countries to be executed at the shortest possible notice to forestall the French and prevent Allied air power from threatening the industrial area of the Ruhr . It would also provide the basis for a long-term air and sea campaign against Britain. There was no mention in the directive of a consecutive attack to conquer the whole of France, although

1287-463: A mass firepower effect in attack or defence. The French numerical advantage in heavy weapons and equipment, which was often deployed in "penny-packets" (dispersed as individual support weapons) was offset. Most French tanks also lacked radio and orders between infantry units were typically passed by telephone or verbally. The German communications system permitted a degree of communication between air and ground forces. Attached to Panzer divisions were

1386-785: A move towards Breda in the Netherlands; if the Allies prevented a German occupation of Holland, the ten divisions of the Dutch army would join the Allied armies, control of the North Sea would be enhanced and the Germans would be denied bases for attacks on Britain. By May 1940, the 1st Army Group was responsible for the defence of France from the Channel coast south to the Maginot Line. The Seventh Army ( Général d'armée Henri Giraud ), BEF (General Lord Gort ), First Army ( Général d'armée Georges Maurice Jean Blanchard ) and Ninth Army ( Général d'armée André Corap ) were ready to advance to

1485-661: A notional line running down the Malay Peninsula , through Singapore and the southernmost islands of the Dutch East Indies . ABDACOM was also known in British military circles as the "South West Pacific Command", although it should not be confused with the later South West Pacific Area command (see below). Although ABDACOM existed only for a few weeks and presided over one defeat after another, it provided some useful lessons for combined Allied commands later in

1584-482: A quick tempo and exploit opportunities faster than the Allies. Panzer divisions could conduct reconnaissance, advance to contact or defend and attack vital positions and weak spots. Captured ground would be occupied by infantry and artillery as pivot points for further attacks. Although many German tanks were outgunned by their opponents, they could lure Allied tanks onto the divisional anti-tank guns. The avoidance of tank-versus-tank engagements conserved German tanks for

1683-679: A result of the defeat of the Netherlands by Nazi Germany in 1940, and the Dutch administration was focused on defending the island of Java ; the Australian government was heavily committed to the war in North Africa and Europe, and had few readily accessible military resources; and the United States was preoccupied with the Philippines, which at the time was a U.S. Commonwealth territory . Wavell arrived in Singapore , where

1782-465: A small number of the best-equipped and " elite divisions were offset by many second and third rate divisions". Army Group A, commanded by Gerd von Rundstedt, comprised 45 + 1 ⁄ 2 divisions, including seven Panzer and was to execute the main movement effort through the Allied defences in the Ardennes. The manoeuvre carried out by the Germans is sometimes referred to as a "Sichelschnitt" ,

1881-417: A trained individual for each task allowed a logical division of labour. French tanks had smaller crews; the commander had to load the main gun, distracting him from observation and tactical deployment. The Germans enjoyed an advantage through the theory of Auftragstaktik (mission command) by which officers, NCOs and men were expected to use their initiative and had control over supporting arms, rather than

1980-809: The Heer (German Army), 1,000,000 of the Luftwaffe (German Air Force), 180,000 of the Kriegsmarine (German Navy) and 100,000 of the Waffen-SS (military arm of the Nazi Party). When consideration is made for those in Poland, Denmark and Norway, the Army had 3,000,000 men available for the offensive starting on 10 May 1940. These manpower reserves were formed into 157 divisions. Of these, 135 were earmarked for

2079-732: The Albert Canal and increased the readiness of the army; Gamelin and Grand Quartier Général (GQG) began to consider the possibility of advancing further than the Escaut. By November, GQG had decided that a defence along the Dyle Line was feasible, despite the doubts of General Alphonse Georges , commander of the North-Eastern Front, about reaching the Dyle before the Germans. The British had been lukewarm about an advance into Belgium, but Gamelin persuaded them; on 9 November,

2178-776: The Allies failed to fulfil their military obligations to Poland, later called the Western betrayal by the Poles. The possibility of Soviet assistance to Poland had ended with the Munich Agreement of 1938, after which the Soviet Union and Germany eventually negotiated the Molotov–Ribbentrop Pact , which included an agreement to partition Poland. The Allies settled on a long-war strategy in which they would complete

2277-560: The British Far East Command was based, on 7 January 1942. ABDACOM absorbed this British command in its entirety. On 18 January, Wavell moved his headquarters to Lembang near Bandoeng on Java . On 1 February the air force portion of ABDA moved its headquarters from Lembang to Bandoeng when it became clear that the former place lacked sufficient accommodation. This made cooperation between air and naval forces difficult. The first notable success for forces under ABDACOM

2376-573: The Dyle river to Antwerp, which was 70–80 km (43–50 mi) shorter than the alternatives. A second possibility was a line from the French border to Condé , Tournai , along the Escaut ( Scheldt ) to Ghent and thence to Zeebrugge on the North Sea coast, possibly further along the Scheldt (Escaut) to Antwerp, which became the Escaut plan/Plan E. The third possibility was along field defences of

2475-472: The Fliegerleittruppen ( Tactical Air Control Party troops) in wheeled vehicles. There were too few Sd.Kfz. 251 command vehicles for all of the army but the theory allowed the army in some circumstances to call Luftwaffe units to support an attack . Fliegerkorps VIII , equipped with Junkers Ju 87 dive-bombers ( Stukas ), was to support the dash to the Channel if Army Group A broke through

2574-691: The French Army , German commanders met with French officials on 18 June to negotiate an end to hostilities. On 22 June 1940, the Second Armistice at Compiègne was signed by France and Germany. The neutral Vichy government led by Marshal Philippe Pétain replaced the Third Republic and German military occupation began along the French North Sea and Atlantic coasts and their hinterlands. The Italian invasion of France over

2673-615: The Panzerwaffe should be concentrated at Sedan. This concentration of armour would advance to the west to the English Channel , without waiting for the main body of infantry divisions. This might lead to a strategic collapse of the enemy, avoiding the relatively high number of casualties normally caused by a Kesselschlacht (cauldron battle). Such a risky independent use of armour had been widely discussed in Germany before

2772-757: The Phoney War (the French Drôle de guerre , joke war or the German Sitzkrieg , sitting war) set in between the belligerents. Adolf Hitler had hoped that France and Britain would acquiesce in the conquest of Poland and quickly make peace. On 6 October, in a speech to the Reichstag he made a peace offer to the Western powers. On 9 October 1939, Hitler issued Führer-Directive Number 6 ( Führer-Anweisung N°6 ). Hitler recognised

2871-596: The United Kingdom and France offered military support to Poland in the likely case of a German invasion. At dawn on 1 September 1939, the German invasion of Poland began. France and the United Kingdom declared war on 3 September, after an ultimatum for German forces immediately to withdraw their forces from Poland was not answered. Australia and New Zealand also declared war on 3 September, South Africa on 6 September and Canada on 10 September. While British and French commitments to Poland were met politically,

2970-715: The Western Campaign ( German : Westfeldzug ), the French Campaign ( Frankreichfeldzug , campagne de France ) and the Fall of France , during the Second World War was the German invasion of the Low Countries ( Belgium , Luxembourg and the Netherlands ) and France . The invasion plan for the Low Countries and France was called Case Yellow ( German , Fall Gelb ). Fall Rot ( Case Red )

3069-554: The 300,000 of the French Army. All of the British Expeditionary Force was motorised. Most of the German logistical transport consisted of horse-drawn vehicles. Only 50 per cent of the German divisions available in 1940 were fit for operations, often being worse equipped than the German army of 1914 or their equivalents in the British and French Armies. In the spring of 1940, the German Army was semi-modern;

3168-698: The ABDA command, which was dissolved a week later. Wavell resigned as supreme commander on 25 February 1942, handing control of the ABDA Area to local commanders. He also recommended the establishment of two Allied commands to replace ABDACOM: a south west Pacific command, and one based in India. In anticipation of this, Wavell had handed control of Burma to the British Indian Army and reassumed his previous position, as Commander-in-Chief India. Following

3267-617: The Alps took a small amount of ground and after the armistice , Italy occupied a small area in the south-east. The Vichy regime retained the zone libre (free zone) in the south. Following the Allied invasion of French North Africa in November 1942, in Case Anton , the Germans and Italians took control of the zone until France was liberated by the Allies in 1944. During the 1930s,

3366-443: The Ardennes and kept a Ju 87 and a fighter group on call. On average, they could arrive to support armoured units within 45–75 minutes of orders being issued. The German army conducted combined arms operations of mobile offensive formations, with well-trained artillery, infantry, engineer and tank formations, integrated into Panzer divisions. The elements were united by wireless communication, which enabled them to work together at

3465-400: The Army should attack early, ready or not, hoping that Allied unreadiness might bring about an easy victory. Hitler proposed an invasion on 25 October 1939 but accepted that the date was probably unrealistic. On 29 October, Halder presented Aufmarschanweisung N°2, Fall Gelb , with a secondary attack on the Netherlands. On 5 November, Hitler informed Walther von Brauchitsch that he intended

3564-410: The Belgian and Luxembourg frontiers. In March 1940, Swiss intelligence detected six or seven Panzer divisions on the German-Luxembourg-Belgian border and more motorised divisions were detected in the area. French intelligence were informed through aerial reconnaissance that the Germans were constructing pontoon bridges about halfway over the Our River on the Luxembourg–German border. On 30 April,

3663-452: The Beveland Peninsula (now the Walcheren – Zuid-Beveland –Noord-Beveland peninsula ) in the Holland Hypothesis . On 12 March 1940, Gamelin discounted dissenting opinion at GQG and decided that the Seventh Army would advance as far as Breda, to link with the Dutch. Georges was told that the role of the Seventh Army on the left flank of the Dyle manoeuvre would be linked to it and Georges notified Billotte that if it were ordered to cross into

He would receive his orders from an appropriate joint body who will be responsible to me as the Minister of Defence and to the President of the United States who is also Commander-in-Chief of all United States forces. Following the declaration by the four nations on 1 January 1942, the Allied governments formally appointed Wavell. The formation of ABDACOM meant that Wavell had control of

3861-427: The British military establishment, the scheme was finalized at the Arcadia Conference in Washington. On December 27 Marshall and Admiral Ernest King proposed an ABDA Command led by Archibald Wavell to Charles Portal , Dudley Pound , and John Dill . The British were skeptical and believed the Pacific theatre was too geographically large to be controlled by a single commander. Winston Churchill warned Marshall about

3960-402: The Dyle Line, by pivoting on the right (southern) Second Army. The Seventh Army would take over west of Antwerp, ready to move into Holland and the Belgians were expected to delay a German advance, then retire from the Albert Canal to the Dyle, from Antwerp to Louvain. On the Belgian right, the BEF was to defend about 20 km (12 mi) of the Dyle from Louvain to Wavre with nine divisions and

4059-465: The Dyle plan was adopted. On 17 November, a session of the Supreme War Council deemed it essential to occupy the Dyle Line and Gamelin issued a directive that day detailing a line from Givet to Namur, the Gembloux Gap, Wavre, Louvain and Antwerp. For the next four months, the Dutch and Belgian armies laboured over their defences, the British Expeditionary Force (BEF) expanded and the French army received more equipment and training. Gamelin also considered

4158-426: The First Army, on the right of the BEF, was to hold 35 km (22 mi) with ten divisions from Wavre across the Gembloux Gap to Namur. The gap from the Dyle to Namur north of the Sambre, with Maastricht and Mons on either side, had few natural obstacles and was a traditional route of invasion, leading straight to Paris. The Ninth Army would take post south of Namur, along the Meuse to the left (northern) flank of

4257-420: The French border from Luxembourg to Dunkirk . For the first fortnight of the war, Gamelin favoured Plan E, because of the example of the fast German advances in Poland. Gamelin and the other French commanders doubted that they could move any further forward before the Germans arrived. In late September, Gamelin issued a directive to Général d'armée Gaston Billotte , commander of the 1st Army Group, ...assuring

4356-417: The French built the Maginot Line , fortifications along the border with Germany . The line was intended to economise on manpower and deter a German invasion across the Franco–German border by diverting it into Belgium, which could then be met by the best divisions of the French Army . The war would take place outside French territory, avoiding the destruction of the First World War . The main section of

4455-445: The French military attaché in Bern warned that the centre of the German assault would come on the Meuse at Sedan, sometime between 8 and 10 May. These reports had little effect on Gamelin, as did similar reports from neutral sources such as the Vatican and a French sighting of a 100 km-long (60 mi) line of German armoured vehicles on the Luxembourg border trailing back inside Germany. Germany had mobilised 4,200,000 men of

4554-425: The General Staff Oberkommando des Heeres [OKH]), presented the first plan for Fall Gelb on 19 October. Fall Gelb entailed an advance through the middle of Belgium; Aufmarschanweisung N°1 envisioned a frontal attack, at a cost of half million German soldiers to attain the limited goal of throwing the Allies back to the River Somme . German strength in 1940 would then be spent and only in 1942 could

4653-436: The German armies there. British , Belgian and French forces were pushed back to the sea by the Germans where the British and French navies evacuated the encircled elements of the British Expeditionary Force (BEF) and the French and Belgian armies from Dunkirk in Operation Dynamo . German forces began Fall Rot ("Case Red") on 5 June 1940. The remaining Allied divisions in France, sixty French and two British, made

4752-530: The German translation of the phrase "sickle cut" coined by Winston Churchill after the event. It involved three armies (the 4th , 12th and 16th ) and had three Panzer corps. The XV had been allocated to the 4th Army but the XLI (Reinhardt) and the XIX (Guderian) were united with the XIV Army Corps of two motorised infantry divisions on a special independent operational level in Panzergruppe Kleist (XXII Corps). Army Group B ( Fedor von Bock ), comprised 29 + 1 ⁄ 2 divisions including three armoured,

4851-403: The Low Countries to outflank the Maginot Line from the north, an attack on the Maginot Line or an invasion through Switzerland. None of the contingencies anticipated the German attack through the Ardennes but after the loss of the Luftwaffe plans, the Germans assumed that the Allied appreciation of German intentions would have been reinforced. Aufmarschanweisung N°3, Fall Gelb , an amendment to

4950-400: The Maginot Line and then south-east through the Stenay Gap, for which the divisions behind the Second Army were well placed. If the Allies could control the Scheldt Estuary, supplies could be transported to Antwerp by ship and contact established with the Dutch Army along the river. On 8 November, Gamelin directed that a German invasion of the Netherlands must not be allowed to progress around

5049-415: The Maginot Line ran from the Swiss border and ended at Longwy ; the hills and woods of the Ardennes region were thought to cover the area to the north. General Philippe Pétain declared the Ardennes to be "impenetrable" as long as "special provisions" were taken to destroy an invasion force as it emerged from the Ardennes by a pincer attack . The French commander-in-chief, Maurice Gamelin , also believed

5148-425: The Moselle but failed to detect the redeployment from the Dutch frontier to the Eifel – Moselle area. On 27 January, Manstein was sacked as Chief of Staff of Army Group A and appointed commander of an army corps in East Prussia . To silence Manstein, Halder had instigated his transfer to Stettin on 9 February. Manstein's staff brought his case to Hitler, who had independently suggested an attack at Sedan, against

5247-405: The Netherlands, the left flank of the army group was to advance to Tilburg if possible and certainly to Breda. The Seventh Army was to take post between the Belgians and Dutch by passing the Belgians along the Albert Canal and then turning east, a distance of 175 km (109 mi), when the Germans were only 90 km (56 mi) distant from Breda. On 16 April, Gamelin also made provision for

5346-455: The Pacific War Council) was established in London on February 9, with a corresponding staff council in Washington. However, the smaller powers continued to push for a body based in the United States. In the meantime, the rapid collapse of Allied resistance to Japanese attacks in Malaya, Singapore, the Dutch East Indies , the Philippines and other countries had soon overwhelmed the Malay Barrier. The fall of Singapore on 15 February dislocated

5445-447: The Second Army. The Second Army was the right (eastern) flank army of the 1st Army Group, holding the line from Pont à Bar 6 km (3.7 mi) west of Sedan to Longuyon . GQG considered that the Second and Ninth armies had the easiest task of the army group, dug in on the west bank of the Meuse on ground that was easily defended and behind the Ardennes, a considerable obstacle, the traversing of which would give plenty of warning of

5544-510: The U.S.-British Combined Chiefs of Staff , which was also in Washington. Although there were relatively few U.S. forces in the Pacific in mid-1942, the sheer volume of matériel and forces controlled by the United States government soon gave it effective control of strategy in the Pacific War.

5643-413: The advice of OKH. On 2 February, Hitler was told of Manstein's plan and on 17 February, Hitler summoned Manstein, General Rudolf Schmundt (Chief of Personnel of the German Army) and General Alfred Jodl , the Chief of Operations of Oberkommando der Wehrmacht (OKW, Supreme Command of the Armed Forces), to a conference. The next day, Hitler ordered Manstein's thinking to be adopted, because it offered

5742-410: The area to be safe from attack, noting it "never favoured large operations". French war games, held in 1938, of a hypothetical German armoured attack through the Ardennes, left the army with the impression that the region was still largely impenetrable and that this, along with the obstacle of the Meuse River , would allow the French time to bring up troops into the area to counter any attack. In 1939,

5841-412: The arrangement despite their concerns. On December 29, Winston Churchill said that it had been agreed Wavell would be supreme commander in order to assuage British concerns. Wavell then held the position of British Commander-in-Chief, India . Churchill added: It is intended that General Wavell should have a staff in the south Pacific accessible as Foch 's High Control Staff was to the Great Staffs of

5940-481: The battle. German tanks had radio receivers that allowed them to be directed by platoon command tanks, which had voice communication with other units. Wireless allowed tactical control and far quicker improvisation than the opponent. Some commanders regarded the ability to communicate to be the primary method of combat and radio drills were considered to be more important than gunnery. Radio allowed German commanders to co-ordinate their formations, bringing them together for

6039-414: The destruction of the ABDA strike force under Rear-Admiral Karel Doorman , at the Battle of the Java Sea , in February–March 1942, ABDA effectively ceased to exist. As the Imperial Japanese Army closed in on the remaining Allied forces in the Philippines, MacArthur was ordered to relocate to Australia. On 17 March, the U.S. government appointed him as Supreme Allied Commander South West Pacific Area ,

6138-445: The difficulties faced by Ferdinand Foch as Supreme Allied Commander while simply trying to coordinate operations across the Western Front of World War I . Marshall rebuffed this and other historical analogies from Churchill, telling him that he "was not interested in Drake and Frobisher , but I was interested in having a united front against Japan." Churchill reluctantly telephoned his War Cabinet in London advising them to accept

6237-408: The directive read that as much as possible of the border areas in northern France should be occupied. On 10 October 1939, Britain refused Hitler's offer of peace and on 12 October, France did the same. The pre-war German codename of plans for a campaign in the Low Countries was Aufmarschanweisung N°1, Fall Gelb (Deployment Instruction No. 1, Case Yellow). Colonel-General Franz Halder (Chief of

6336-431: The east (right flank) and attack on the west (left flank) by advancing into Belgium, to fight forward of the French frontier . The extent of the forward move was dependent on events, which were complicated when Belgium ended the Franco-Belgian Accord of 1920 after the German Remilitarisation of the Rhineland on 7 March 1936. The neutrality of the Belgian state was reluctant openly to co-operate with France but information

6435-435: The expense of Army Group B to the north. While Manstein was formulating new plans in Koblenz , Generalleutnant Heinz Guderian , commander of the XIX Army Corps , was lodged in a nearby hotel. Manstein was initially considering a move north from Sedan, directly in the rear of the main Allied mobile forces in Belgium. When Guderian was invited to contribute to the plan during informal discussions, he proposed that most of

6534-410: The field army would have needed more troops than the British Expeditionary Force.) The 88 mm Flak had an elevation of −3° to +85° and could be used as artillery i.e. against panzers. The armies which invaded the west had 85 heavy and 18 light batteries belonging to the Luftwaffe , 48 companies of light Flak integral to divisions of the army and 20 companies of light Flak allocated as army troops,

6633-403: The flanks. Hitler made such a suggestion on 11 November, pressing for an early attack on unprepared targets. Halder's plan satisfied no-one; General Gerd von Rundstedt , the commander of Army Group A ( Heeresgruppe A ) recognised that it did not adhere to the classic principles of Bewegungskrieg ( war of manoeuvre ) that had guided German strategy since the 19th century. A breakthrough

6732-443: The integrity of the national territory and defending without withdrawing the position of resistance organised along the frontier.... giving the 1st Army Group permission to enter Belgium, to deploy along the Escaut according to Plan E. On 24 October, Gamelin directed that an advance beyond the Escaut was only feasible if the French moved fast enough to forestall the Germans. By late 1939, the Belgians had improved their defences along

6831-463: The invasion to begin on 12 November. Brauchitsch replied that the military had yet to recover from the Polish campaign and offered to resign; this was refused but two days later Hitler postponed the attack, giving poor weather as the reason for the delay. More postponements followed, as commanders persuaded Hitler to delay the attack for a few days or weeks, to remedy some defect in the preparations or to wait for better weather. Hitler also tried to alter

6930-420: The invasion, Hitler, who had spoken to forces on the Western Front and who was encouraged by the success in Norway , confidently predicted the campaign would take only six weeks. He was most excited over the planned military glider attack on Fort Eben-Emael . On 3 September 1939, French military strategy had been settled, taking in analyses of geography, resources and manpower. The French Army would defend in

7029-401: The limited Saar Offensive but by mid-October had withdrawn to their start lines. German armies invaded Belgium , Luxembourg , the Netherlands , and France on 10 May 1940. In Fall Gelb ("Case Yellow"), German armoured units made a surprise push through the Ardennes and then along the Somme valley, cutting off and surrounding the Allied units that had advanced into Belgium to meet

7128-473: The main attack against France begin. When Hitler raised objections to the plan and wanted an armoured breakthrough, as had happened in the invasion of Poland, Halder and Brauchitsch attempted to dissuade him, arguing that while the fast-moving mechanised tactics were effective against a "shoddy" Eastern European army, they would not work against a first-rate military like the French. Hitler was disappointed with Halder's plan and initially reacted by deciding that

7227-584: The necessity of military campaigns to defeat the Western European nations, preliminary to the conquest of territory in Eastern Europe, to avoid a two-front war but these intentions were absent from Directive N°6. The plan was based on the seemingly more realistic assumption that German military strength would have to be built up for several years. Only limited objectives could be envisaged and were aimed at improving Germany's ability to survive

7326-512: The next stage of the offensive, units carrying supplies for three to four days' operations. The Panzer divisions were supported by motorised and infantry divisions. German tank battalions ( Panzer-Abteilungen ) were to be equipped with the Panzerkampfwagen III and Panzerkampfwagen IV tanks but shortages led to the use of light Panzerkampfwagen II and even lighter Panzerkampfwagen I instead. The German Army lacked

7425-457: The offensive, including 42 reserve divisions. The German forces in the west in May and June deployed some 2,439 tanks and 7,378 guns. In 1939–40, 45 per cent of the army was at least 40 years old and 50 per cent of all the soldiers had just a few weeks' training. The German Army was far from motorised; ten per cent of their army was motorised in 1940 and could muster only 120,000 vehicles, compared with

Perhaps the most notable success for ABDA forces was the guerilla campaign in Timor , waged by Australian and Dutch infantry for almost 12 months after Japanese landings there on February 19.

7623-460: The plan on 30 January, was only a revision of details. On 24 February, the main German effort was moved south to the Ardennes. Twenty divisions (including seven panzer and three motorised divisions) were transferred from Heeresgruppe B opposite Holland and Belgium to Heeresgruppe A facing the Ardennes. French military intelligence uncovered a transfer of German divisions from the Saar to the north of

7722-432: The plan, which he found unsatisfactory; his weak understanding of how poorly prepared Germany was for war and how it would cope with losses of armoured vehicles were not fully considered. Though Poland had been quickly defeated, many armoured vehicles had been lost and were hard to replace. This led to the German effort becoming dispersed; the main attack would remain in central Belgium, secondary attacks would be undertaken on

7821-625: The possibility of decisive victory. Hitler recognised the breakthrough at Sedan only in tactical terms, whereas Manstein saw it as a means to an end. He envisaged an operation to the English Channel and the encirclement of the Allied armies in Belgium; if the plan succeeded, it could have a strategic effect. Halder then went through an "astonishing change of opinion", accepting that the Schwerpunkt should be at Sedan. He had no intention of allowing an independent strategic penetration by

7920-651: The rearmament plans of the 1930s while fighting a defensive land war against Germany and weakening its war economy with a trade blockade , ready for an eventual invasion of Germany. On 7 September, in accordance with the Franco-Polish alliance , France began the Saar Offensive with an advance from the Maginot Line 5 km (3 mi) into the Saar . France had mobilised 98 divisions (all but 28 of them reserve or fortress formations) and 2,500 tanks against

8019-522: The seven Panzer divisions of Army Group A. Much to the dismay of Guderian, this element was absent from the new plan, Aufmarschanweisung N°4, Fall Gelb , issued on 24 February. The bulk of the German officer corps was appalled and called Halder the "gravedigger of the Panzer force". Even when adapted to more conventional methods, the new plan provoked a storm of protest from the majority of German generals. They thought it utterly irresponsible to create

8118-466: The slower, top-down methods of the Allies. Army Group B had the support of 1,815 combat aircraft, 487 transport aircraft and 50 gliders; 3,286 combat aircraft supported Army Groups A and C. The Luftwaffe was the most experienced, well-equipped and well-trained air force in the world. The combined Allied total was 2,935 aircraft, about half the size of the Luftwaffe . The Luftwaffe could provide close support with dive-bombers and medium bombers but

8217-546: The smaller powers continued to push for a Washington-based body. The Pacific War Council was formed in Washington on April 1, 1942, with a membership consisting of President Franklin D. Roosevelt , his key advisor Harry Hopkins , and representatives from Britain, China , Australia, New Zealand, the Netherlands and Canada . Representatives from India and the Philippines were later added. Australia and New Zealand (Prime Ministers John Curtin and Peter Fraser ) wanted

8316-471: The spot . In return, the United States undertook the establishment of close working arrangements with the three military missions so they could give informed advice. Both Australia and New Zealand accepted under protest. Much of the impetus for the council was lost during the collapse of ABDACOM , in March and April. The council never had any direct operational control and any decisions it made were referred to

8415-698: The war but OKH doubted such an operation could work. Manstein's general operational ideas won immediate support from Guderian, who understood the terrain, having experienced the conditions with the German Army in 1914 and 1918. Manstein wrote his first memorandum outlining the alternative plan on 31 October. In it he avoided mentioning Guderian and played down the strategic part of the armoured units, to avoid unnecessary resistance. Six more memoranda followed between 31 October 1939 and 12 January 1940, each becoming more radical. All were rejected by OKH and nothing of their content reached Hitler. On 10 January 1940,

8514-631: The war. Efforts to organise the ABDA Command began soon after war between the Allies and Japan commenced, on 7 December 1941. Army Chief of Staff George C. Marshall and Secretary of War Henry L. Stimson were anxious to establish unity of command over the Allied forces in all theatres after observing Allied defeats in the Battle of France , the Mediterranean and Middle East theatre , and the attack on Pearl Harbor . Despite objections from

8613-399: The west of Antwerp and gain the south bank of the Scheldt. The left flank of the 1st Army Group was reinforced by the Seventh Army, containing some of the best and most mobile French divisions, which moved from the general reserve by December. The role of the army was to occupy the south bank of the Scheldt and be ready to move into Holland and protect the estuary by holding the north bank along

8712-508: Was a broadly based force, intended to support national strategy and could carry out operational, tactical and strategic bombing operations. Allied air forces were mainly intended for army co-operation but the Luftwaffe could fly air superiority missions, medium-range interdiction , strategic bombing and close air support operations, depending on circumstances. It was not a Panzer spearhead arm, since in 1939 fewer than 15 per cent of Luftwaffe aircraft were designed for close support as this

8811-595: Was added to the ABDA area. The rest of Australia was under Australian control, as were its territories of Papua and New Guinea . ABDA was charged with holding the Malay Barrier for as long as possible in order to retain Allied control of the Indian Ocean and the western sea approaches to Australia. This was a nearly hopeless task, given the Japanese supremacy in naval forces in the western Pacific. The task

8910-413: Was communicated about Belgian defences. By May 1940, there had been an exchange of the general nature of French and Belgian defence plans but little co-ordination against a German offensive to the west, through Luxembourg and eastern Belgium. The French expected Germany to breach Belgian neutrality first, providing a pretext for French intervention or that the Belgians would request support when an invasion

9009-405: Was further complicated by the addition of Burma to the command; the difficulties of coordinating action between forces of four nationalities that used different equipment and had not trained together; and the different priorities of the national governments. British leaders were primarily interested in retaining control of Singapore ; the military capacity of the Dutch East Indies had suffered as

9108-533: Was imminent. Most of the French mobile forces were assembled along the Belgian border, ready to forestall the Germans. An early appeal for help might give the French time to reach the German–Belgian frontier but if not, there were three feasible defensive lines further back. A practicable line existed from Givet to Namur , across the Gembloux Gap ( la trouée de Gembloux ), Wavre , Louvain and along

9207-410: Was needed to encircle and destroy the main body of Allied forces. The most practical place to achieve this would be in the region of Sedan , which lay in the sector of Army Group A. On 21 October, Rundstedt agreed with his chief of staff , Generalleutnant Erich von Manstein , that an alternative operational plan to reflect these principles was needed, by making Army Group A as strong as possible at

9306-428: Was not its main role. The Germans had an advantage in anti-aircraft guns ( Fliegerabwehrkanone [ Flak ]), with 2,600 88 mm (3.46 in) heavy Flak guns and 6,700 37 mm (1.46 in) and 20 mm (0.79 in) . Light Flak refers to the number of guns in the German armed forces, including the anti-aircraft defence of Germany and the equipment of training units. (A 9,300-gun Flak component with

9405-614: Was planned to finish off the French and British after the evacuation at Dunkirk. The Low Countries and France were defeated and occupied by Axis troops down to the Demarcation line , ending land operations on the Western Front until the Normandy landings on 6 June 1944. On 3 September 1939, France and Britain declared war on Germany, over the German invasion of Poland on 1 September. In early September 1939, France began

9504-759: Was technically subordinate to Wavell, but in reality, many of the chains of command shown here operated independently of ABDACOM and/or existed only on paper. ) Air forces (ABDAIR) Naval forces (ABDAFLOAT) Battle of France Germany : 27,074 killed 111,034 wounded 18,384 missing 1,129 airmen killed 1,236 aircraft lost 795–822 tanks lost German: 156,547 Italian: 6,029–6,040 Asia-Pacific Mediterranean and Middle East Other campaigns Coups Luxembourg The Netherlands Belgium France Britain 1941–1943 1944–1945 Germany Strategic campaigns The Battle of France ( French : bataille de France ; 10 May – 25 June 1940), also known as

9603-525: Was the U.S. Navy's attack at Balikpapan , Borneo on January 24, which cost the Japanese six transport ships, but had little effect on them capturing the prized oil wells of Borneo. The governments of Australia, the Netherlands and New Zealand lobbied Winston Churchill for an Allied inter-governmental war council, with overall responsibility for the Allied war effort in Asia and the Pacific, based in Washington, D.C. A Far Eastern Council (later known as

9702-649: Was the short-lived supreme command for all Allied forces in South East Asia in early 1942, during the Pacific War in World War II . The command consisted of the forces of Australia , the Netherlands , United Kingdom and the United States . The main objective of the command, led by General Sir Archibald Wavell , was to maintain control of the " Malay Barrier " (or "East Indies Barrier"),

9801-441: Was to advance through the Low Countries and lure the northern units of the Allied armies into a pocket. It was composed of the 6th and 18th Armies. Army Group C, (General Wilhelm Ritter von Leeb ) comprising 18 divisions of the 1st and 7th Armies, was to prevent a flanking movement from the east and with launching small holding attacks against the Maginot Line and the upper Rhine . Wireless proved essential to German success in
