55-774: The Joint Intelligence Operations Center Europe (JIOCEUR) Analytic Center (JAC), formerly known as the Joint Analysis Center , is a Joint Intelligence Center serving as a military intelligence analysis centre for the United States European Command located at RAF Molesworth , Cambridgeshire , United Kingdom and managed by the Defense Intelligence Agency . The area of responsibility includes over 50 countries in Europe , 33 Sub-Saharan and West African countries, and

110-618: A broad front in Normandy would permit simultaneous threats against the port of Cherbourg , coastal ports further west in Brittany, and an overland attack towards Paris and eventually into Germany. Normandy was hence chosen as the landing site. The most serious drawback of the Normandy coast—the lack of port facilities—would be overcome through the development of artificial Mulberry harbours . A series of modified tanks, nicknamed Hobart's Funnies , dealt with specific requirements expected for

165-525: A central position around Paris and Rouen and deploying them only when the main Allied beachhead had been identified. He also noted that in the Italian Campaign , the armoured units stationed near the coast had been damaged by naval bombardment. Rommel's opinion was that because of Allied air supremacy, the large-scale movement of tanks would not be possible once the invasion was under way. Hitler made

220-465: A few days. Rommel believed that Germany's best chance was to stop the invasion at the shore. He requested that the mobile reserves, especially tanks, be stationed as close to the coast as possible. Rundstedt, Geyr, and other senior commanders objected. They believed that the invasion could not be stopped on the beaches. Geyr argued for a conventional doctrine: keeping the Panzer formations concentrated in

275-659: A further postponement would have meant a delay of at least two weeks, as the planners had requirements for the phase of the moon, the tides, and time of day, that meant only a few days each month were deemed suitable. Adolf Hitler placed Field Marshal Erwin Rommel in command of German forces and developing fortifications along the Atlantic Wall in anticipation of an invasion. US President Franklin D. Roosevelt placed Major General Dwight D. Eisenhower in command of Allied forces. The invasion began shortly after midnight on

330-459: A joint intelligence operation. In September 1943 the first designated JIC was Admiral Chester W. Nimitz 's Pacific Ocean Areas JIC (JICPOA). JICPOA integrated the staff and independent intelligence distribution system of the Navy's earlier Pearl Harbor intelligence center and was the largest independent theatre intelligence operation. Supreme Headquarters Allied Expeditionary Force JIC (SHAEFJIC)

385-642: A misinformation campaign using fake radio traffic to lead the Germans into expecting an attack on Norway, and Fortitude South, a major deception involving the creation of a fictitious First United States Army Group under Lieutenant General George S. Patton , supposedly located in Kent and Sussex . Fortitude South was intended to deceive the Germans into believing that the main attack would take place at Calais . Genuine radio messages from 21st Army Group were first routed to Kent via landline and then broadcast, to give

Joint Intelligence Center There are Joint Intelligence Centers in the United States Central Command at Tampa, Florida, the United States Indo-Pacific Command in Hawaii, and in Europe. The Joint Analysis Center serves as a JIC for the United States European Command . The United States declared war in 1941 with two separate organizations gathering and distributing intelligence for operational planning. The Office of Naval Intelligence (ONI) had been formed in 1882; while

495-585: The 2nd SS Panzer Division "Das Reich" , had only arrived in France in March–May 1944 for extensive refit after being badly damaged during the Dnieper-Carpathian operation. Seven of the eleven panzer or panzergrenadier divisions stationed in France were not fully operational or only partially mobile in early June 1944. German Supreme commander: Adolf Hitler Allied forces attacking Utah Beach faced

550-570: The Avranches - Falaise line within the first three weeks. Montgomery envisaged a ninety-day battle, lasting until all Allied forces reached the River Seine . Under the overall umbrella of Operation Bodyguard, the Allies conducted several subsidiary operations designed to mislead the Germans as to the date and location of the Allied landings. Operation Fortitude included Fortitude North,

Several hundred of these messages, which might be snippets of poetry, quotations from literature, or random sentences, were regularly transmitted, masking the few that were significant. In the weeks preceding the landings, lists of messages and their meanings were distributed to resistance groups. An increase in radio activity on 5 June was correctly interpreted by German intelligence to mean that an invasion

715-847: The German Army invaded the Soviet Union in June 1941, the Soviet leader Joseph Stalin began pressing his new allies for the creation of a second front in western Europe. In late May 1942, the Soviet Union and the United States made a joint announcement that a "... full understanding was reached with regard to the urgent tasks of creating a second front in Europe in 1942." However, British Prime Minister Winston Churchill persuaded US President Franklin D. Roosevelt to postpone

770-743: The Low Countries , with another eighteen stationed in Denmark and Norway. Fifteen divisions were in the process of formation in Germany. Combat losses throughout the war, particularly on the Eastern Front , meant that the Germans no longer had a pool of able young men from which to draw. German soldiers were now on average six years older than their Allied counterparts. Many in the Normandy area were Ostlegionen (eastern legions)—conscripts and volunteers from Russia, Mongolia, and other areas of

825-518: The Luftwaffe and established air supremacy over western Europe, so Rommel knew he could not expect effective air support. The Luftwaffe could muster only 815 aircraft over Normandy in comparison to the Allies' 9,543. Rommel arranged for booby-trapped stakes known as Rommelspargel ( Rommel's asparagus ) to be installed in meadows and fields to deter airborne landings. German armaments minister Albert Speer notes in his 1969 autobiography that

880-631: The Middle East . The Joint Analysis Center was a conglomeration of Air Force (497th RTG / 496th RTS), Army and Navy intelligence assets from throughout the European Theatre. Personnel from the 496th RTS were key in planning and facilitating the movement of equipment and personnel into the JAC. In January 2015, the DoD announced that Molesworth and RAF Alconbury were to close. In accordance with

935-603: The landing operations and associated airborne operations on 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during the Second World War . Codenamed Operation Neptune and often referred to as D-Day (after the mililtary term ), it is the largest seaborne invasion in history. The operation began the liberation of France , and the rest of Western Europe, and laid the foundations of

990-467: The Allied advance at a relatively narrow isthmus, so these sites were rejected. With the Pas-de-Calais being the closest point in continental Europe to Britain, the Germans considered it to be the most likely initial landing zone, so it was the most heavily fortified region. But it offered few opportunities for expansion, as the area is bounded by numerous rivers and canals, whereas, landings on

1045-463: The Allied victory on the Western Front . Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception , codenamed Operation Bodyguard , to mislead the Germans as to the date and location of the main Allied landings. The weather on the day selected for D-Day was not ideal, and the operation had to be delayed 24 hours;

1100-407: The Allies to land at high tide so that the infantry would spend less time exposed on the beach, he ordered many of these obstacles to be placed at the high water mark . Tangles of barbed wire, booby traps , and the removal of ground cover made the approach hazardous for infantry. On Rommel's order, the number of mines along the coast was tripled. The Allied air offensive over Germany had crippled

1155-922: The Army's Military Information Division had been established in 1885, and reorganized in 1917 as the Military Intelligence Division (MID). Although the Commandant of the Marine Corps proposed a joint effort in March 1942 interservice rivalry prevented formation of a Joint Intelligence Agency (JIA). In preparation for the Guadalcanal Campaign the Navy established an intelligence center at Pearl Harbor in July 1942. Consolidated intelligence collection began as US forces went on

1210-522: The Atlantic coast, from Spain to Norway, to protect against an expected Allied invasion. He envisioned 15,000 emplacements manned by 300,000 troops, but shortages, particularly of concrete and manpower, meant that most of the strongpoints were never built. As it was expected to be the site of the invasion, the Pas de Calais was heavily defended. In the Normandy area, the best fortifications were concentrated at

1265-674: The Atlantic meant German meteorologists had less information than the Allies on incoming weather patterns. As the Luftwaffe meteorological centre in Paris was predicting two weeks of stormy weather, many Wehrmacht commanders left their posts to attend war games in Rennes , and men in many units were given leave. Field Marshal Erwin Rommel returned to Germany for his wife's birthday and to petition Hitler for additional Panzer divisions. Germany had at its disposal fifty divisions in France and

The British at Sword and Gold Beaches and the Canadians at Juno Beach would protect the US flank and attempt to establish airfields near Caen on the first day. (A sixth beach, code-named "Band", was considered to the east of the Orne). A secure lodgement would be established with all invading forces linked together, with an attempt to hold all territory north of

1430-651: The German high command, concerned about the susceptibility of the airports and port facilities along the North Sea coast, held a conference on 6–8 June 1944 to discuss reinforcing defences in that area. Speer wrote: In Germany itself we scarcely had any troop units at our disposal. If the airports at Hamburg and Bremen could be taken by parachute units and the ports of these cities seized by small forces, invasion armies debarking from ships would, I feared, meet no resistance and would be occupying Berlin and all of Germany within

1485-610: The Germans the impression that most of the Allied troops were stationed there. Patton was stationed in England until 6 July, thus continuing to deceive the Germans into believing a second attack would take place at Calais. Many of the German radar stations on the French coast were destroyed in preparation for the landings. In addition, on the night before the invasion, a small group of Special Air Service operators deployed dummy paratroopers over Le Havre and Isigny . These dummies led

1540-468: The Germans to believe that an additional airborne landing had occurred. On that same night, in Operation Taxable , No. 617 Squadron RAF dropped strips of "window", metal foil that caused a radar return which was mistakenly interpreted by German radar operators as a naval convoy near Le Havre. The illusion was bolstered by a group of small vessels towing barrage balloons . A similar deception

The decision to undertake a cross-channel invasion within the next year was taken at the Trident Conference in Washington in May 1943. Initial planning was constrained by the number of available landing craft, most of which were already committed in

1650-753: The London-based État-major des Forces Françaises de l'Intérieur ( French Forces of the Interior ), the British Special Operations Executive orchestrated a campaign of sabotage to be implemented by the French Resistance . The Allies developed four plans for the Resistance to execute on D-Day and the following days: The resistance was alerted to carry out these tasks by messages personnels transmitted by

1705-721: The Mediterranean and Pacific . At the Tehran Conference in November 1943, Roosevelt and Churchill promised Stalin that they would open the long-delayed second front in May 1944. The Allies considered four sites for the landings: Brittany , the Cotentin Peninsula , Normandy, and the Pas-de-Calais . As Brittany and Cotentin are peninsulas, it would have been possible for the Germans to cut off

1760-759: The Normandy Campaign such as mine clearing, demolishing bunkers, and mobile bridging. The Allies planned to launch the invasion on 1 May 1944. The initial draft of the plan was accepted at the Quebec Conference in August 1943. General Dwight D. Eisenhower was appointed commander of the Supreme Headquarters Allied Expeditionary Force . General Bernard Montgomery was named commander of the 21st Army Group , which comprised all land forces involved in

1815-416: The Normandy coast could be a possible landing point for the invasion, so he ordered the construction of extensive defensive works along that shore. In addition to concrete gun emplacements at strategic points along the coast, he ordered wooden stakes, metal tripods, mines, and large anti-tank obstacles to be placed on the beaches to delay the approach of landing craft and impede the movement of tanks. Expecting

The British and Commonwealth air and naval support units included a large number of personnel from Allied nations, including several RAF squadrons manned almost exclusively by overseas air crew. For example, the Australian contribution to

1980-412: The amphibious invasion and establishment of a secure foothold, was codenamed Operation Neptune. To gain the air superiority needed to ensure a successful invasion, the Allies undertook a bombing campaign (codenamed Operation Pointblank ) that targeted German aircraft production, fuel supplies, and airfields. Elaborate deceptions, codenamed Operation Bodyguard , were undertaken in the months leading up to

2035-406: The expanded operation meant that the invasion had to be delayed to June. Eventually, thirty-nine Allied divisions would be committed to the Battle of Normandy: twenty-two American, twelve British, three Canadian, one Polish, and one French, totalling over a million troops. Operation Overlord was the name assigned to the establishment of a large-scale lodgement on the continent. The first phase,

2145-439: The five landing sites on the first day, but Carentan , Saint-Lô , and Bayeux remained in German hands. Caen , a major objective, was not captured until 21 July. Only two of the beaches (Juno and Gold) were linked on the first day, and all five beachheads were not connected until 12 June. German casualties on D-Day have been estimated at 4,000 to 9,000 men. Allied casualties were at least 10,000, with 4,414 confirmed dead. After

2255-399: The invasion to prevent the Germans from learning the timing and location of the invasion. The landings were to be preceded by airborne operations near Caen on the eastern flank to secure the Orne River bridges and north of Carentan on the western flank. The Americans, assigned to land at Utah Beach and Omaha Beach, were to attempt to capture Carentan and Saint-Lô the first day, then cut off

2310-444: The invasion would have required recalling men and ships already in position to cross the English Channel and would have increased the chance that the invasion plans would be detected. After much discussion with the other senior commanders, Eisenhower decided that the invasion should go ahead on 6 June. A major storm battered the Normandy coast from 19 to 22 June, which would have made the beach landings impossible. Allied control of

2365-454: The invasion. On 31 December 1943, Eisenhower and Montgomery first saw the plan, which proposed amphibious landings by three divisions with two more divisions in support. The two generals insisted that the scale of the initial invasion be expanded to five divisions, with airborne descents by three additional divisions, to allow operations on a wider front and to hasten the capture of Cherbourg. The need to acquire or produce extra landing craft for

2420-645: The landing craft east of their intended positions, particularly at Utah and Omaha. The men landed under heavy fire from gun emplacements overlooking the beaches, and the shore was mined and covered with obstacles such as wooden stakes, metal tripods , and barbed wire, making the work of the beach-clearing teams difficult and dangerous. The highest number of casualties was at Omaha, with its high cliffs. At Gold, Juno, and Sword, several fortified towns were cleared in house-to-house fighting , and two major gun emplacements at Gold were disabled using specialised tanks. The Allies were able to establish beachheads at each of

2475-537: The landings for shortly before dawn, midway between low and high tide, with the tide coming in. This would improve the visibility of obstacles on the beach while minimising the amount of time the men would be exposed in the open. Eisenhower had tentatively selected 5 June as the date for the assault. However, on 4 June, conditions were unsuitable for a landing: high winds and heavy seas made it impossible to launch landing craft, and low clouds would prevent aircraft from finding their targets. The weather forecast that reported

2530-457: The morning of 6 June with extensive aerial and naval bombardment as well as an airborne assault —the landing of 24,000 American , British, and Canadian airborne troops . The early morning aerial assault was soon followed by Allied amphibious landings on the coast of France c.   06:30. The target 50-mile (80 km) stretch of the Normandy coast was divided into five sectors: Utah , Omaha , Gold , Juno , and Sword . Strong winds blew

2585-688: The offensive in 1943 and 1944. Formation of Joint Intelligence Collection Agencies (JICA) began in August 1943. North Africa (JICANA) later became Mediterranean (JICAMED). Africa-Middle East was (JICAME). China-India-Burma (JICACIB) later split into China (JICAC) and India-Burma. JICAs transmitted information to the Joint Intelligence Agency Reception Center (JIARC) in Washington DC where a Joint Electronic Information Agency (JEIA) utilized coded radio transmissions to reduce dissemination time for important intelligence from 60 days to 16 hours. Some theatre commanders resisted coordinated efforts, and General Douglas MacArthur 's Southwest Pacific Area (SWPA) never formed

2640-435: The operation included a regular Royal Australian Air Force (RAAF) squadron, nine Article XV squadrons , and hundreds of personnel posted to RAF units and RN warships. The RAF supplied two-thirds of the aircraft involved in the invasion. [REDACTED] 79th Armoured Division : Major General Percy Hobart provided specialised armoured vehicles which supported the landings on all beaches in Second Army's sector. Through

Rommel was assigned to oversee the construction of further fortifications along the expected invasion front, which stretched from the Netherlands to Cherbourg, and was given command of the newly re-formed Army Group B, which included the 7th Army, the 15th Army , and the forces guarding the Netherlands. Reserves for this group included the 2nd , 21st, and 116th Panzer divisions. Rommel believed that

2750-428: The promised invasion as, even with US help, the Allies did not have adequate forces for such an activity. Instead of an immediate return to France, the western Allies staged offensives in the Mediterranean Theatre of Operations , where British troops were already stationed. By mid-1943, the campaign in North Africa had been won. The Allies then launched the invasion of Sicily in July 1943 and subsequently invaded

2805-464: The storms was sent from a weather station on the western coast of Ireland. Group Captain James Stagg of the Royal Air Force (RAF) met Eisenhower on the evening of 4   June. He and his meteorological team predicted that the weather would improve enough for the invasion to proceed on 6 June. The next available dates with the required tidal conditions (but without the desirable full moon) would be two weeks later, from 18 to 20 June. Postponement of
