Why did Rommel retreat to Tunisia?

Field Marshal Erwin Rommel retreated to Tunisia in early 1943 primarily due to the strategic situation on the North African front. After suffering significant losses in the Second Battle of El Alamein and facing the encroaching British Eighth Army, Rommel needed to regroup and fortify his defenses. The retreat allowed him to consolidate his forces in Tunisia, where he hoped to establish a more defensible position against Allied advances. Additionally, the supply lines to his troops were increasingly stretched and vulnerable, necessitating a tactical withdrawal.
