The Battle of Kasserine Pass (February 14–24, 1943) was the first major engagement between U.S. forces and German and Italian troops during World War II. Fought in the Atlas Mountains of Tunisia, the offensive was launched by Erwin Rommel to disrupt Allied efforts to advance into the region.12

Initially, the Axis forces achieved significant success, exploiting poor communication and fragmented command structures within the U.S. II Corps. German Panzer units, utilizing superior tanks, forced the inexperienced American troops to retreat in disarray. However, the Axis advance was eventually stalled by difficult terrain, severe weather, and stiffening Allied resistance, including effective artillery fire and reinforcements.12

Recognizing that the opportunity for a breakthrough had passed, Rommel ended the offensive on February 22 and withdrew to face the British Eighth Army to the south. While the battle was a humiliating setback for the Americans, they recovered quickly. The engagement led to the replacement of Major General Lloyd Fredendall with George S. Patton and prompted Dwight D. Eisenhower to implement new combat doctrines emphasizing strong air support.12
