Joining a Soviet military convoy, Beyrle arrived at the US embassy in Moscow in February 1945, only to learn that he had been reported by the US War Department as killed in action on June 10, 1944 on French soil. A funeral mass had been held in his honor in Muskegon, and his obituary was published in the local newspaper. Embassy officers in Moscow, unsure of his bona fides, placed him under Marine guard in the Metropol Hotel until his identity was established through his fingerprints.
