Task Force 45

Introduction:
Task Force 45 was a polyglot task force of American and British antiaircraft gunners acting as infantry, with Italian Partisans, Brazilians and colored American troops fighting by their side. Its artillery were the antiaircraft guns pointing earthward, the guns of tanks and tank destroyers and of captured German weapons. Its engineers were Italian civilians who were not afraid to work within the sounds of guns and who built well. It did much with little. British Tommies who rode forward on American tanks, with American mortars behind and American engineers forward, and the Yanks who stepped out of their foxholes with British artillery pounding protection behind, with Italians at their side and out ahead and with Brazilians on their flanks, learned that different peoples can fight well together.
