Operation Citadel was a major German offensive during World War II, launched in July 1943. Its primary goal was to encircle and destroy the Soviet forces in the area around Kursk, which was a key point on the Eastern Front. The operation aimed to regain the initiative after previous defeats and to secure a decisive victory. The operation involved a massive buildup of troops and armor, making it one of the largest tank battles in history. However, the Soviet Red Army was well-prepared and had fortified defenses. Ultimately, the offensive failed, marking a turning point in the war in favor of the Soviets.
