Frederick was drafted in February 1942. He was immediately identified as "officer material" and sent to officer candidate training. We do not know of his previous assignments but he was already a 1LT when transferred from the replacement depot to Headquarters and Headquarters Company 3rd Battalion 116th Infantry as Company Commander on 28 Jun 1944. He was not long in his assignment as he was killed in action on 8 Jul 1944 while the regiment fought to liberate Saint-Lo, France.
1LT Ulrey was repatriated in 1948 and re-interred in Arlington National Cemetery in Arlington, Virginia.
Frederick and Kathryn had no children. Kathryn never re-married.
