when did the allies enter world war 2
Allies of World War II At the start of the war on 1 September 1939, the Allies consisted of France, Poland and the United Kingdom, as well as their dependent states, such as British India. Within days they were joined by the independent Dominions of the British Commonwealth: Australia, Canada, New Zealand and South Africa.[1] After the start of the German invasion of North Europe until the Balkan Campaign, the Netherlands, Belgium, Greece, and Yugoslavia joined the Allies. After first having cooperated with Germany in invading Poland whilst remaining neutral in the Allied-Axis conflict, the Soviet Union perforce joined the Allies in June 1941 after being invaded by Germany. The United States provided war materiel and money all along, and officially joined in December 1941 after the Japanese attack on Pearl Harbor. China had already been in a prolonged war with Japan since the Marco Polo Bridge Incident of 1937, but officially joined the Allies in 1941.
Invasion of Normandy The Western Allies of World War II launched the largest amphibious invasion in history when they assaulted Normandy, located on the northern coast of France, on 6 June 1944. The invaders were able to establish a beachhead as part of Operation Overlord after a successful "D-Day," the first day of the invasion.
Triple Entente Historians continue to debate the importance of the alliance system as one of the causes of World War I. At the start of World War I in 1914, all three Triple Entente members entered it as Allies against the Central Powers: Germany and Austria-Hungary.[1]
Battle of Britain Bombing of London was to be held back while these night time "destroyer" attacks proceeded over other urban areas, then in culmination of the campaign a major attack on the capital was intended to cause a crisis when refugees fled London just as the Operation Sea Lion invasion was to begin.[128] With hopes fading for the possibility of invasion, on 4 September Hitler authorised a main focus on day and night attacks on tactical targets with London as the main target, in what the British called the Blitz. With increasing difficulty in defending bombers in day raids, the Luftwaffe shifted to a strategic bombing campaign of night raids aiming to overcome British resistance by damaging infrastructure and food stocks, though intentional terror bombing of civilians was not sanctioned.[129]
