An excerpt from the description of Sr. Edeltrud Cook also describes the end of the war in the abbey - no word about any American POW, only one from Armenia:
The Americans approached Siegburg... The German soldiers, and also Waffen-SS, fought for their positions ... The Americans beat the Germans. Armed soldiers rushed to the basement and drove us up into the cloister. Here we had to stand for a long Long time with arms [arm like leg, not weapons] raised. Around us they still shot. The Americans believed that there were many German soldiers still hiding, but this was not confirmed. Fear and dread kept us under control. Finally, it was announced: men and women separately in a detention center. The judgment startled us very much; hopeless and helpless we were delivered. But then we got God's help and support. Daniel, an Armenian prisoner of war, as a wounded man who was healed in the hospital tried to negotiate with the Americans. He still had a document that testified how well he was treated as a prisoner and also received the goodwill of the whole house. The "winners" yielded, took Daniel's watch, and went. We were saved from the "camp" and remained on the hill.
