Your cousins' Army Serial Number was 35932589.Year of birth 1922, enlisted 8/31/43. Service with Pattons' 3rd Army won't be of much help because dozens of units served within the various Corps in the European Theater and even the Corps were moved from army to army. The European Theater in which Patton served consisted of the 12th US Army Group (General Omar Bradley) and the 21st Army Group-British(General Bernard Montgomery), US Armies on continent were 1st-Hodges, 3rd-Patton, 9th-Simpson, 15th-Gerow (paper basically) and later the 7th-Patch. A reference to his tank would of course indicate an Armored Division but does not help narrow the search too much, as there were over a dozen US Armored divisions in which he could have served. Remember US divisions strength during WWII was roughly 15,000 men, and each Corps was comprised of between 3-6 divisions, quite a task. My advice would be to check with the courthouses in nearby counties in which he may have lived upon his return, as many vets filed copies of their discharge papers,VFW memberships,State records for service bonuses, and the VA for possible claims files which may yield service units. The easiest way to determine units of assignment would be to check with relatives living who may have letters received from him during wartime, these will yield his unit in abbreviated form but this list can translate for you, or if old uniforms are still existing which may have his division patch or unit heraldic crest which we can also identify. Keep us posted! Rick
