During the planning for the invasion of the Italian mainland, the 82nd was tasked with taking Rome by coup de main in Operation Giant II. Ridgway strongly objected to this unrealistic plan, which would have dropped the 82nd on the outskirts of the Italian capital of Rome in the midst of two German heavy divisions. The operation was canceled only hours before launch. The 82nd did, however, play a significant role in the Allied invasion of Italy at Salerno in September which, but for a drop by Ridgway's two parachute regiments, may well have seen the Allies pushed back into the sea. The 82nd Airborne Division subsequently saw brief service in the early stages of the Italian Campaign, helping the Allies to break through the Volturno Line in October. The division then returned to occupation duties in the recently liberated Italian city of Naples and saw little further action thereafter and in November departed Italy for Northern Ireland. Lieutenant General Mark W. Clark, commander of the Fifth United States Army, a fellow graduate of the West Point class of 1917, referring to Ridgway as an "outstanding battle soldier, brilliant, fearless and loyal", who had "trained and produced one of the finest Fifth Army outfits", was unwilling to give up either Ridgway or the 82nd. As a compromise, Colonel Tucker's 504th Parachute Infantry Regiment, along with supporting units, was retained in Italy, to be sent to rejoin the rest of the 82nd Airborne Division as soon as possible.
