In July 1943 the Allies launched a massive amphibious assault on Sicily. The invasion proved successful, bringing fame to American Gen. George S. Patton and British Gen. Bernard Montgomery, whose "race" to Messina was immortalized in the movie Patton. But according to Mitcham and Stauffenberg, the Allies lost a significant opportunity for total victory when the Germans mounted a brilliant defense. With only 4 divisions, the Germans held off the invaders for 38 days and then escaped, almost entirely intact, to mainland Italy, dooming the Allies to a prolonged battle of attrition up the Italian peninsula.
