Major General Terry de la Mesa Allen, Sr. (1888–1969) was the son of Colonel Samuel Edward Allen and Conchita Alvarez de la Mesa. During World War II he was the commanding general of the 1st Infantry Division in North Africa and Sicily, and was made commander of the 104th Infantry Division. While in North Africa Allen and his deputy 1st Division Commander, Brigadier General Theodore Roosevelt Jr. distinguished themselves as combat leaders. Allen was reassigned to the 104th Infantry Division. The 104th Infantry Division landed in France on September 7, 1944, and fought for 195 consecutive days during World War II. The division's nickname came from its timberwolf shoulder insignia. Some 34,000 men served with the division under Allen, who came to be nicknamed "Terrible Terry". The division was particularly renowned for its night fighting prowess.
