For clarification, once the war in Europe ended, there was a long process of disarming the thousands of merchant ships. Armed Guard personnel were kept on ships until the guns were removed. In some cases, this was a skeleton crew. The general rule was that guns were not removed until the vessel was designated as permanently being assigned to a non-combat area. Many vessels were destined for the Pacific theater, and many more had an unknown future. Even after the war ended in the Pacific, the process of removing the guns and thus, removing the Armed Guards, went on for a long period of time. As late as September 1946 there were still over 100 men assigned to the Armed Guard. So, it is not that unusual that someone would be assigned to a vessel, like the American Flyer, after the war ended.
