The Mühlviertler Hasenjagd (lit. 'Mühlviertel rabbit hunt') was a war crime in which 500 Soviet officers, who had revolted and escaped from the Mühlviertel subcamp of Mauthausen-Gusen concentration camp on 2 February 1945, were hunted down. Local civilians, soldiers and local Nazi organizations hunted down the escapees for three weeks, executing most of them. Of the original 500 prisoners who took part in the escape attempt, eleven succeeded in remaining free until the end of the war. The mass escape was unique in Mauthausen's history.
