After serving in the Operation Torch landings in North Africa and the Tunisia Campaign, followed by participation in the Allied invasion of Sicily, Roosevelt was assigned as assistant division commander of the 4th Infantry Division. In this role, he led the first wave of troops ashore at Utah Beach during the Normandy landings in June 1944. He died in France of a heart attack the following month; at the time of his death, he had been recommended for the Distinguished Service Cross to recognize his heroism at Normandy. The recommendation was subsequently upgraded, and Roosevelt was a posthumous recipient of the Medal of Honor.
