Oliver was assigned to the
1st Armored Division in January 1942, a month after the
Japanese attack on Pearl Harbor and the subsequent American entry into
World War II, to assume command of
Combat Command 'B' (CCB), then promoted to the
one-star general officer rank of
brigadier general on February 16, 1942. The division deployed to
Northern Ireland on May 6, 1942, to train for eventual operations in
French North Africa. In September, Oliver went to
London,
England to assist in the planning for
Operation Torch (
Allied invasion of North Africa). Oliver was promoted to the
two-star rank of
major general on November 20, 1942, CCB encountered its first major enemy resistance at
Medjez-el-bab,
Tunisia where they fought for fours days starting on December 6, 1942. Oliver returned to the United States and was appointed commander of the
5th Armored Division, where he succeeded Brigadier General
Sereno E. Brett at
Camp Cooke in early 1943. Oliver led the division throughout the remainder of the war, including training in the
Mojave Desert near
Needles, California, through March 1943, the Tennessee Maneuvers through the Summer, and final validation and reorganization of the division at
Pine Camp (Now Fort Drum, New York) through the winter into early 1944. Oliver led the division on two ships to England, arriving on February 24, 1944, in preparation for the Allied
invasion of Normandy. The division served on the
Western Front starting with landing on
Utah Beach on July 26, 1944, until
Victory in Europe Day on May 8, 1945, and after. The 5th Armored Division, under Major General Oliver's command, was the first division to reach the
Seine River, the first division to reach
Luxembourg, the first division to fight in Germany, and when halted by orders from the
U.S. Ninth Army, the division sat 45 miles from
Berlin, closer than any other American division. A street in
Luxembourg City is named in honour of Major General Lunsford E. Oliver. He died in
Newington, Connecticut, on October 13, 1978, and was buried at
West Point Cemetery. ==Decorations==
