Major General Roderick Random Allen (January 29, 1894 - February 1, 1970) was a senior United States Army officer, who commanded the 20th and 12th Armored Divisions during World War II. Under his command of the 12th AD, the division defended Strasbourg from recapture against overwhelming odds; it provided the armored contingent in the closure of the Colmar Pocket and the liberation of Colmar; it spearheaded General George Patton's drive to the Rhine; captured intact the remaining bridge over the Danube River and broke the German defense line, making it the first time in recorded history that the Danube had failed to stop an invading army; and played a major part in blocking the Brenner Pass, thereby trapping over a million German soldiers in Italy as the war ended. En route to the Brenner Pass it overran eleven concentration camps at Landsberg, Germany.
