There is no 6th Cavalry Division, nor has there ever been. You're probably looking for the 28th Cavalry Reconnaissance Squadron, 6th Cavalry Group - formerly 2d Squadron, 6th Cavalry. The 3d Cavalry Regiment was constituted in May 1861 and organized a month later. Redesignated 6th Cavalry in August, the regiment carried that designation for over 80 years. 6th Cavalry arrived in Great Britain in October 1943. On 1 January 1944, the regiment was reorganized and redesignated thusly: Regimental Headquarters & Headquarters Troop (H&HT) and 3d Squadron became H&HT, 6th Cavalry Group; 1st Squadron became 6th Cavalry Reconnaissance Squadron and 2d Squadron became 28th Cavalry Reconnaissance Squadron. 6th Cavalry Group didn't arrive in France until 9 July 1944. You can use his service number (above) to order his IDPF (see message #1656, this forum). IF they can locate his file and IF the file is complete, it will include the exact date, place and cause of death - IF the form was filled in properly.
