Timeline of World War II
From Academic Kids
For events preceding September 1, 1939, see the timeline of events preceding World War II.
September 1, 1939
- The Polish September Campaign begins as Poland is attacked by Germany at 4:30 AM with Luftwaffe air attacks against several targets. The United Kingdom and France demand immediate withdrawal by Germany. See timeline of the Polish September Campaign for detailed chronology of this campaign.
- The United Kingdom home front is opened as the government declares general mobilisation of the British Army and begins evacuation plans to prepare for German attacks by air. See timeline of the United Kingdom home front during World War II for more detailed chronology on this aspect.
September 3, 1939
- The politics and diplomacy of World War II begin with the frantic responses of governments to the attack on Poland. The United Kingdom, along with Australia and New Zealand, declare war at 11:15 AM. France joins the war at 5:00 PM. A number of nations have declared their neutrality by this point or will do so in the coming weeks while South Africa and Canada will join the Allies at war in the next few days. See timeline of politics and diplomacy during World War II for a detailed chronology of these events.
- The Second Battle of the Atlantic begins as the German Navy goes into action to begin denial of the United Kingdom's shipping lanes almost immediately after the United Kingdom's declaration of war with Germany. This campaign would last for the duration of the war, and pit Germany's submarine force, surface raiders, and maritime aircraft against the Allies' merchant shipping convoys and their escorts. See timeline of the Second Battle of the Atlantic for a detailed chronology of this campaign.
September 4, 1939
- Allied air operations in Europe begin with raids by the Royal Air Force targets on German naval targets. Early raids are small, but build through the war to become a steady campaign of strategic bombardment against targets throughout Axis-occupied territory in Europe that would only end with the defeat of the Axis in Europe. See timeline of Allied air operations in Europe for a detailed chronology of this campaign.
September 7, 1939
- French patrols enter Germany near Saarbrücken. These continue through September 17, 1939, in anticipation of a larger advance. This larger advance is cancelled in part due to the collapse of Poland, leading a lack of operational activity during the period from then to the Battle of France named the Phony War. Meanwhile, the British Expeditionary Force begins arriving in France and takes up positions along the Belgian frontier. See the timeline of the Battle of France for a detailed chronology of the events of the Phony War and the lead up to the Battle of France.
September 10, 1939
- Canada declares war on Germany. In World War I, Canada had automatically been at war when Britain declared war. However, increased independence gained during the 1920s lead to Canada declaring war on a separate date.
September 17, 1939
- The Soviet Union invades Poland from the east, occupying the territory east of the Curzon line as well as Bialystok and Eastern Galicia.
September 25, 1939
