The European theatre of World War II opened with the German invasion of Poland on Friday September 1, 1939 and the Soviet invasion of Poland on September 17, 1939.
 The Polish Army was defeated after more than a month of fierce fighting.
 After Poland had been overrun, a government-in-exile (headquartered in Britain), armed forces, and an intelligence service were established outside of Poland.
 These organizations contributed to the Allied effort throughout the war.
 The Polish Army was recreated in the West, as well as in the East (after the German invasion of the Soviet Union).

Günther Blumentritt (10 February 1892 – 12 October 1967) was an officer in World War I, who became a Staff Officer under the Weimar Republic and went on to serve as a general for Nazi Germany during World War II.
 He served throughout the war, mostly on the Western Front, and mostly as a Staff Officer, though he was eventually given his own Corps and made a "General der Infanterie".
 Blumentritt was instrumental in planning the 1939 German invasion of Poland and the 1940 invasion of France, he participated in Operation "Barbarossa", and afterward bore a large part of the responsibility for planning the defense of the Atlantic Wall and Normandy.
 After the war, Blumentritt gave an affidavit at the Nuremberg Trials, though he never testified in person, and then later helped in the rearmament of Germany during the Cold War and the development of the modern German army.
The Darkest Hour is a phrase coined by British prime minister Winston Churchill to describe the period of World War II between the fall of France in 1940 and the Nazi invasion of the Soviet Union in 1941, when the British Empire stood alone against Nazi Germany and the Axis Powers in Europe.
 The length of time between the fall of France in June 1940 and the German invasion of the Soviet Union in June 1941 measured 363 days, or 11 months and 28 days.
 It is particularly used for the time when the United Kingdom was under direct threat of invasion; following the evacuation of the British Army from Dunkirk and prior to victory in the Battle of Britain.
 The darkest moment is usually considered to have been 10 May 1941, when over 1,500 civilians died in Luftwaffe bombing raids on London alone.
