It’s a striking image — with two Polish Army soldiers firing at enemy Germans and a third seemingly knocked from his ladder. The rooftop in suburban Warsaw doesn’t look particularly stable, but during the German invasion of Poland, soldiers were determined. The explosion you can see is plaster cascading out of the house, as a result of German gunfire. The German invasion of Poland marked the beginning of the war for many and began on September 1st, 1939 — with the Soviet invasion starting two weeks later.  By October 6th, Germany and the Soviet Union were dividing the country under the terms of the German-Soviet Frontier Treaty.
