The Schutzmannschaft Battalion 201 was a World War II Schutzmannschaft auxiliary police battalion (Schuma) formed by Nazi Germans on October 21, 1941, predominantly from the soldiers of Ukrainian Nachtigall Battalion dissolved two months prior. Nachtigall was a Security Police unit composed almost exclusively from members of the OUN(b), who were transported from Vinnytsia to Neuhammer on August 13, 1941 and disarmed at gunpoint due to political disagreement with the German leadership.
