After training in the United States for several months Eddy led the division overseas, landing in French North Africa on November 8, 1942 as part of Operation Torch. The 9th Division fought in the subsequent Alliedcampaign in North Africa, and played a large role in the Battle of Kasserine Pass in February 1943. The campaign came to an end in May 1943, with the surrender of almost 250,000 Axis soldiers.
Eddy led the 9th Division in the early stages of Operation Overlord, codename for the Battle of Normandy, landing on Utah Beach four days after the D-Day landings of June 6, 1944. For his role in the capture of the French port of Cherbourg,[10] which much impressed his superiors, Eddy was awarded the Distinguished Service Cross.[11] In the opinion of General Dwight D. Eisenhower, Eddy had outperformed all the other American divisional commanders in Normandy, and he had slated Eddy to take over the next available corps.[2]
In the postwar period, Eddy served again at Fort Leavenworth, Kansas, this time as Commandant of the United States Army Command and General Staff College, from January 1948 to July 1950. He was president of a review board that made a thorough examination of officer education and established the progressive branch, staff, and senior service levels of officer schooling. As commander of the Seventh Army, he presided over its transformation from an army of occupation to one of deterrence. Eddy retired from the army with the rank of lieutenant general.[14][15]
