Germany's Invasions of Poland
At 4:45 a.m., some 1.5 million German troops invade Poland all along its 1,750-mile border with German-controlled territory. Simultaneously, the German Luftwaffe bombed Polish airfields, and German warships and U-boats attacked Polish naval forces in the Baltic Sea.

German Blitzkrieg
A German term for “lightning war,” blitzkrieg is a military tactic designed to create disorganization among enemy forces through the use of mobile forces and locally concentrated firepower. Its successful execution results in short military campaigns, which preserves human lives and limits the expenditure of artillery. German forces tried out the blitzkrieg in Poland in 1939 before successfully employing the tactic with invasions of Belgium, the Netherlands and France in 1940.
