It was located in the city of Baia Mare (Hungarian: Nagybánya) in Maramureș County, Transylvania, now part of Romania but administered as part of Szatmár County by the Kingdom of Hungary from the 1940 Second Vienna Award's grant of Northern Transylvania until late 1944. It was active in the spring of 1944, following Operation Margarethe.
