حملة البلقان
In May 1941 part of Oflag XIII-A Langwasser, Nuremberg, was separated off, and a new camp, designated Oflag XIII-B, created for Yugoslavian officers, predominantly Serbs captured in the Balkans Campaign. In April 1943 at least 3,000 Serbian officers were moved from Langwasser to Hammelburg. Many were members of the Yugoslavian General Staff, some of whom had been POWs in Germany during the First World War.
