Blitzkrieg was a military strategy developed and employed by the German forces during World War II. The term "Blitzkrieg" translates to "lightning war" in English. It aimed to achieve quick and overwhelming victory through the use of concentrated forces, speed, and surprise. First used by the Germans in the invasion of Poland in 1939, Blitzkrieg relied on the close coordination between tanks, infantry, artillery, and aircraft. The strategy involved fast-moving armored divisions, supported by airpower, that would break through enemy lines and encircle their forces. The intent of Blitzkrieg was to disorient and demoralize the enemy, disrupting their command structure and preventing effective resistance. By rapidly advancing and exploiting weaknesses, the Germans sought to overwhelm their opponents before they could mount an organized and effective defense.
