In 1920 the cavalry captain, "Rittmeister" Stephan von le Fort (1884–1953) from Gut Boek, gathered a group of Freikorps fighters around him and imposed a state of siege on the town of Waren during the Kapp Putsch on 17 March 1920. On 18 March, he and his cousin, Reichswehr lieutenant Peter Alexander von le Fort, gave orders for a cannon and three machine guns to open fire on the town from Gallows Hill ("Galgenberg"), resulting in five deaths and eleven seriously wounded. After the putsch was suppressed, both men fled to Munich and Austria and the family seat was seized by the Free State of Mecklenburg-Strelitz. At the back of Waren Town Hall a bullet hole can still be seen today as reminder of the affair.
