This presentation explores US General George Patton's “race to Messina” with British General Bernard Montgomery during the Allied invasion of Sicily in 1943. Using Patton’s diaries, the memoirs of his colleagues, and official military reports, this research proves that his decision to deviate from the plan in competition with Montgomery allowed the evacuation of approximately 100,000 Axis soldiers. These soldiers continued fighting on the Italian mainland, which slowed the Allied advancements. Military historians consistently understate the consequences of his actions, but this research proves that Patton was the main cause for the strategic failure of preventing an Axis evacuation. This presentation demonstrates the consequences of jealousy-driven military decisions, which in this case prolonged a war.
