Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the town was occupied by Germany until 1945. Local units of the Grey Ranks and Wielkopolska Organizacja WojskowaPolish resistance organizations were founded already in 1939, and the latter became part of the larger Wojskowa Organizacja Ziem Zachodnich organization in 1940.[2] Klemens Jan Grygiel, commander of the local unit of the Grey Ranks, and Edward Paulus, founder of the local unit of the Union of Armed Struggle, were arrested by the Germans in mid-1942, and eventually sentenced to death and executed in Rawicz the following year.[3]
