117-688: World War II The Inner Mongolian Army , also sometimes called the Mengjiang National Army , referred to the Inner Mongolian military units in service of Imperial Japan and its puppet state of Mengjiang during the Second Sino-Japanese War , particularly those led by Prince Demchugdongrub . It was primarily a force of cavalry units, which mostly consisted of ethnic Mongols , with some Han Chinese infantry formations. After Japanese intrigues led to
234-659: A Neutrality Pact in April 1941, and Japan adopted the doctrine of Nanshin-ron , promoted by the Navy, which took its focus southward and eventually led to war with the United States and the Western Allies. In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany annexed Austria , again provoking little response from other European powers. Encouraged, Hitler began pressing German claims on
351-578: A cautious French probe into the Saarland . The Western Allies also began a naval blockade of Germany , which aimed to damage the country's economy and war effort.

However, he himself still considers this less likely than the "accidental shot" hypothesis, that the first shot was fired by a low-ranking Chinese soldier in "an unplanned moment of fear". In comparison to their Japanese counterparts, the 29th Route Army, and generally all of the NRA for that matter, was poorly equipped and under-trained. Most soldiers were armed only with
585-572: A Japanese naval officer was shot in Shanghai , escalating the skirmishes and battles into full scale warfare. The 29th Army's resistance (and poor equipment) inspired the 1937 " Sword March ", which with reworked lyrics became the NRA's standard marching cadence and popularized the racial epithet guizi to describe the Japanese invaders. The heightened tensions of the Marco Polo Bridge incident led directly to full-scale war between
702-627: A cavalry division under the Muslim General Ma Biao to be sent east to battle the Japanese. The Turkic Salar people made up the majority of the first cavalry division sent by Ma. In 1987, the bridge was renovated and the People's Anti-Japanese War Museum was built near the bridge to commemorate the anniversary of the start of the Sino-Japanese War. There is debate over whether the incident could have been planned like
819-717: A client state, Manchukuo , with Puyi , the deposed Qing dynasty emperor, as its chief of state. After the invasion, Japanese forces extended their control further into northern China, seeking to obtain raw materials and industrial capacity. A commission of inquiry from the League of Nations published the Lytton Report which was critical of the Japanese, resulting in Japan quitting the League. The Kuomintang (KMT) government of China refused to recognize Manchukuo but did agree to

In addition they wore a leather bandolier for cartridges which was slung over the left shoulder. Some soldiers were dressed in loose fitting cotton jacket and trousers along with a peak cap. In 1936 a new uniform was in use, modeled on the Nationalist Chinese uniform. It included

Private Shimura later returned to his unit; he claimed to have sought immediate relief in the darkness from a stomach ache and become lost ); according to Peter Harmsen, he had visited a brothel. By that time both sides were mobilizing, with the Japanese deploying reinforcements to surround Wanping . Later that night,

The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
1521-781: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as

Its headquarters and bulk for its forces were in Tianjin, with
1755-475: A secret protocol that defined German and Soviet "spheres of influence" (western Poland and Lithuania for Germany; eastern Poland , Finland, Estonia , Latvia and Bessarabia for the Soviet Union), and raised the question of continuing Polish independence. The pact neutralised the possibility of Soviet opposition to a campaign against Poland and assured that Germany would not have to face the prospect of
1872-722: A similar pact and rejected ceding part of its territory to the Soviet Union. The Soviet Union invaded Finland in November 1939, and was subsequently expelled from the League of Nations for this crime of aggression. Despite overwhelming numerical superiority, Soviet military success during the Winter War was modest, and the Finno-Soviet war ended in March 1940 with some Finnish concessions of territory . In June 1940,
1989-613: A snowstorm on 16 November was likewise beaten back by Chinese machine guns. A surprise counterattack by the Nationalists on 17 November resulted in the Inner Mongolian Army and its allies being forced to retreat and regroup at their headquarters in Bailingmiao , where they received some training from the Japanese. The Nationalist General Fu Zuoyi then led an assault on the city, using three trucks to break through

The whole operation
2223-531: A two-front war, as it had in World War I. Immediately afterwards, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland and that Italy would maintain neutrality, he decided to delay it. In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which served as
2340-508: A unit of Japanese infantry attempted to breach Wanping's walled defenses but were repulsed. An ultimatum by the Japanese was issued two hours later. As a precautionary measure, Qin Dechun , the acting commander of the Chinese 29th Route Army, contacted the commander of the Chinese 37th Division, General Feng Zhi'an , ordering him to place his troops on heightened alert. At 02:00 on 8 July, Qin Dechun , executive officer and acting commander of
2457-604: The Anglo-German Naval Agreement and the German–Polish declaration of non-aggression . The situation became a crisis in late August as German troops continued to mobilise against the Polish border. On 23 August the Soviet Union signed a non-aggression pact with Germany, after tripartite negotiations for a military alliance between France, the United Kingdom, and Soviet Union had stalled. This pact had

In June 1941, Germany led the European Axis in an invasion of
2691-581: The German Revolution of 1918–1919 , and a democratic government, later known as the Weimar Republic , was created. The interwar period saw strife between supporters of the new republic and hardline opponents on both the political right and left. Italy, as an Entente ally, had made some post-war territorial gains; however, Italian nationalists were angered that the promises made by the United Kingdom and France to secure Italian entrance into
2808-709: The German invasion of Poland and the United Kingdom and France 's declaration of war on Germany two days later on 3 September 1939. Dates for the beginning of the Pacific War include the start of the Second Sino-Japanese War on 7 July 1937, or the earlier Japanese invasion of Manchuria , on 19 September 1931. Others follow the British historian A. J. P. Taylor , who stated that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and

Both Italy and Ethiopia were member nations, but the League did little when the former clearly violated Article X of the League's Covenant . The United Kingdom and France supported imposing sanctions on Italy for the invasion, but the sanctions were not fully enforced and failed to end the Italian invasion. Italy subsequently dropped its objections to Germany's goal of absorbing Austria . When civil war broke out in Spain, Hitler and Mussolini lent military support to
3510-657: The Manchurian Strategic Offensive Operation . The few Inner Mongolian cavalry units that engaged the Soviets proved to be no match for the battle-hardened Red Army and were swept aside, with the Mongolian regime falling shortly after Japan surrendered. Prince De Wang led the army (which consisted of six divisions at the time, two cavalry and four infantry, and some independent brigades) in battle personally. Three divisions were destroyed by

Italy supported the Nationalists to a greater extent than the Nazis: Mussolini sent more than 70,000 ground troops, 6,000 aviation personnel, and 720 aircraft to Spain. The Soviet Union supported the existing government of the Spanish Republic . More than 30,000 foreign volunteers, known as the International Brigades , also fought against

4212-590: The Soviet–Japanese Neutrality Pact in April 1941. By contrast, the Germans were steadily making preparations for an attack on the Soviet Union, massing forces on the Soviet border. Hitler believed that the United Kingdom's refusal to end the war was based on the hope that the United States and the Soviet Union would enter the war against Germany sooner or later. On 31 July 1940, Hitler decided that

Soon the United Kingdom and France followed the appeasement policy of British Prime Minister Neville Chamberlain and conceded this territory to Germany in the Munich Agreement , which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands. Soon afterwards, Germany and Italy forced Czechoslovakia to cede additional territory to Hungary, and Poland annexed

The Second Italo-Ethiopian War was a brief colonial war that began in October 1935 and ended in May 1936. The war began with
4680-458: The Tanggu Truce with Japan in 1933. Subsequently, there were various "incidents", or armed clashes of a limited nature, followed by a return to uneasy peace. The significance of the Marco Polo Bridge incident is that, following it, tensions did not subside again; instead, there was an escalation, with larger forces committed by both sides and fighting spreading to other parts of China. With hindsight, this small incident can, therefore, be regarded as
4797-466: The Trans-Olza region of Czechoslovakia. Although all of Germany's stated demands had been satisfied by the agreement, privately Hitler was furious that British interference had prevented him from seizing all of Czechoslovakia in one operation. In subsequent speeches Hitler attacked British and Jewish "war-mongers" and in January 1939 secretly ordered a major build-up of the German navy to challenge British naval supremacy. In March 1939, Germany invaded

4914-506: The Treaty of Craiova . The loss of one-third of Romania's 1939 territory caused a coup against King Carol II, turning Romania into a fascist dictatorship under Marshal Ion Antonescu , with a course set towards the Axis in the hopes of a German guarantee. Meanwhile, German-Soviet political relations and economic co-operation gradually stalled, and both states began preparations for war. In April 1940, Germany invaded Denmark and Norway to protect shipments of iron ore from Sweden , which

No formal peace treaty between Japan and the Soviet Union was ever signed, although the state of war between the two countries was terminated by the Soviet–Japanese Joint Declaration of 1956 , which also restored full diplomatic relations between them. World War I had radically altered

Using newly captured French ports, the German Navy enjoyed success against an over-extended Royal Navy , using U-boats against British shipping in the Atlantic . The British Home Fleet scored a significant victory on 27 May 1941 by sinking the German battleship Bismarck . In November 1939,

However, the Japanese Army had been given orders not to advance further than the Yongding River. In a sudden volte-face , the Konoe government's foreign minister opened negotiations with Chiang Kai-shek 's government in Nanjing and stated: "Japan wants Chinese cooperation, not Chinese land." Nevertheless, negotiations failed to move further. On 9 August 1937,

However, this proved to be fruitless, and the Japanese insisted that they be admitted into the town to investigate the cause of the incident. At around 04:00, reinforcements of both sides began to arrive. The Chinese also rushed an extra division of troops to the area. At 04:45 Wang Lengzhai had returned to Wanping, and on his way back he witnessed Japanese troops massing around

With the situation in Europe and Asia relatively stable, Germany, Japan, and the Soviet Union made preparations for war. With the Soviets wary of mounting tensions with Germany, and the Japanese planning to take advantage of the European War by seizing resource-rich European possessions in Southeast Asia , the two powers signed
6552-426: The Germans, and the last large operational unit of the Polish Army surrendered on 6 October . Despite the military defeat, Poland never surrendered; instead, it formed the Polish government-in-exile and a clandestine state apparatus remained in occupied Poland. A significant part of Polish military personnel evacuated to Romania and Latvia; many of them later fought against the Axis in other theatres of

The Nationalists won the civil war in April 1939; Franco, now dictator, remained officially neutral during World War II but generally favoured the Axis . His greatest collaboration with Germany was the sending of volunteers to fight on the Eastern Front . In July 1937, Japan captured

7371-418: The Soviet Union and Mongolia . The Japanese doctrine of Hokushin-ron , which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. This policy would prove difficult to maintain in light of the Japanese defeat at Khalkin Gol in 1939, the ongoing Second Sino-Japanese War and ally Nazi Germany pursuing neutrality with the Soviets. Japan and the Soviet Union eventually signed
7488-575: The Soviet Union should be eliminated and aimed for the conquest of Ukraine , the Baltic states and Byelorussia . However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued

In September the United States further agreed to a trade of American destroyers for British bases . Still, a large majority of the American public continued to oppose any direct military intervention in
