On June 16th, 1944, Edward Gunn led a reconnaissance patrol to La Londe, France to gain information from the enemy. After being fired at by the enemy, the patrol withdrew. Gunn, however, was missing in action, along with two others in his patrol. While this area was eventually taken by U.S. troops, intensive searching yielded no remains. It is assumed that Gunn died while leading his patrol, as a member described hearing Gunn “groan” when the enemy opened fire. He is believed to have died in the vicinity of Caumont, France. Gunn had been assigned to this regiment only a few days prior to his disappearance. As a result, he was relatively unknown among his last company.
Gunn is memorialized in Starkville's Oddfellow's Cemetary and Normandy's American Cemetary. His grave in Mississippi is maintained by Bill Gunn.
