Nazi Germany’s invasion of Poland on 1 September 1939, and Britain and France’s declaration of war on Germany two days later marks the beginning of World War II. After the declaration of war, western Europe saw very little land or air active military confrontation at first, and the period was termed the “Phoney War”. In eastern Europe, however, the agreement between the Soviet Union and Nazi Germany signed on 23 August opened the way in September for the Soviet Union’s invasion of eastern Poland, which was divided between the two invaders before the end of the month. The Soviet Union starts a new military offensive by invading Finland at the end of November.
The Allies and Axis powers at the dawn of the German/Soviet invasion of Poland
September 1, 1939 Each of the following took place:
1: The Republic of China and the Empire of Japan are involved in the early stages of the third year of armed conflict between them during the Second Sino-Japanese War. The war is in what will be known as the “Second Period”, which starts after the fall of Wuhan in October 1938 and ends in December 1941 with Pearl Harbor. This conflict will eventually be swept up into World War II when Japan joins the Axis and China joins the Allies.
1: The invasion of Poland by Germany starts at 4:45 a.m. when the Kriegsmarine’s battleship Schleswig-Holstein opens fire on the Polish military transit depot at Westerplatte in the Free City of Danzig on the Baltic Sea, but the attack is repulsed. At the same time the Luftwaffe attacks several targets in Poland, among them Wieluń, the first town in the war to be carpet bombed by the Germans. Shortly before 6:00 a.m., the German Army passes the Polish border in great numbers from north and south, together with Slovak units. In the same day, the Free City of Danzig is annexed by Germany. Resisters entrenched in the city’s Polish Post Office are overwhelmed.
1: The Italian government announces that it will maintain a condition of “non-belligerence” in the conflict.
1: Norway, Sweden, Denmark, Finland, Latvia and Estonia as well as Romania immediately declare their neutrality.
1: The House of Commons of the United Kingdom passes an emergency military budget.
1: The British War Secretary Leslie Hore-Belisha orders the War Office to begin the general mobilization of the British Armed Forces.
1: In a mass evacuation effort (code named “operation Pied Piper”) the British authorities relocate 1,473,000 children and adults from the cities to the countryside. The adults involved were teachers, people with disabilities and their helpers, mothers with preschool children.
1: Acting on account of their governments, the ambassadors of France and Britain demand the German government to cease all hostile activities and to withdraw its troops from Poland.
1: The President of the United States Franklin Delano Roosevelt sends an appeal to all European powers involved in the crisis asking them to abstain from bombing civilian and unfortified cities. Germany’s Führer, Adolf Hitler, answers immediately assuring the American chargé d’affaires Alexander C. Kirk that the Luftwaffe will only attack military targets. The British Prime Minister Neville Chamberlain also promises to abide to the request, as does Poland’s ambassador to the US Jerzy Antoni Potocki.
