Defense of the Great WallThe defense of the Great Wall () (January 1 – May 31, 1933) was a campaign between the armies of Republic of China and Empire of Japan, which took place before the Second Sino-Japanese War officially commenced in 1937 and after the Japanese invasion of Manchuria in 1931. It is known in Japanese as Operation Nekka and in many English sources as the First Battle of Hopei. During this campaign, Japan successfully captured the Inner Mongolian province of Rehe from the Chinese warlord Zhang Xueliang, and incorporated it into the newly created state of Manchukuo, whose southern frontier was thus extended to the Great Wall of China.
Europe firstEurope first, also known as Germany first, was the key element of the grand strategy agreed upon by the United States and the United Kingdom during World War II after the United States joined the war in December 1941. According to this policy, the United States and the United Kingdom would use the preponderance of their resources to subdue Nazi Germany in Europe first. Simultaneously, they would fight a holding action against Japan in the Pacific, using fewer resources.
KantokuenKantokuen (関特演, from 関東軍特種演習, Kantōgun Tokushu Enshū, "Kwantung Army Special Maneuvers") was an operational plan created by the General Staff of the Imperial Japanese Army for an invasion and occupation of the Russian Far East, capitalizing on the outbreak of the Soviet-German War in June 1941. Involving seven Japanese armies and a major portion of the empire's naval and air forces, it would have been the largest combined arms operation in Japanese history up to that point, and one of the largest of all time.
Battle of YenangyaungThe Battle of Yenangyaung () was fought in Burma, now Myanmar, during the Burma Campaign in World War II. The battle of Yenaungyaung was fought in the vicinity of Yenangyaung and its oil fields. After the Japanese captured Rangoon in March 1942, the Allies regrouped in Central Burma. The newly formed Burma Corps, commanded by Lieutenant General William Slim and consisting of British, Indian and locally raised Burmese troops, attempted to defend the Irrawaddy River valley, while the Chinese Expeditionary Force (in Burma) defended the Sittaung River valley to the east.
Pacification of ManchukuoThe Pacification of Manchukuo was a Japanese counterinsurgency campaign to suppress any armed resistance to the newly established puppet state of Manchukuo from various anti-Japanese volunteer armies in occupied Manchuria and later the Communist Northeast Anti-Japanese United Army. The operations were carried out by the Imperial Japanese Kwantung Army and the collaborationist forces of the Manchukuo government from March 1932 until 1942, and resulted in a Japanese victory.
China Burma India TheaterChina Burma India Theater (CBI) was the United States military designation during World War II for the China and Southeast Asian or India–Burma (IBT) theaters. Operational command of Allied forces (including U.S. forces) in the CBI was officially the responsibility of the Supreme Commanders for South East Asia or China. However, US forces in practice were usually overseen by General Joseph Stilwell, the Deputy Allied Commander in China; the term "CBI" was significant in logistical, material and personnel matters; it was and is commonly used within the US for these theaters.
