Among Distinguished Service Cross recipients for valor in the early battles in Vietnam were four members of the 1st Cavalry Division decorated for valor in the Battle of Ia Drang Valley in November 1965 – Lt. Col. Hal Moore, Major Bruce Crandall and two other members of their unit. The actions of all four were later portrayed in the film ""We Were Soldiers"", based on Hal Moore's book on the battle. Crandall's Distinguished Service Cross was later upgraded to the Medal of Honor, which was presented to him in February 2007.
