Gamratka is a village in the administrative district of Gmina Mińsk Mazowiecki, within Mińsk County, Masovian Voivodeship, in east-central Poland.[2] It lies approximately 5km (03miles) west of Mińsk Mazowiecki and 350NaN0 east of Warsaw.
Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the village was occupied by Germany. On July 27, 1943, the German gendarmerie carried out a massacre of two Poles and three Jews, whom they sheltered from the Holocaust.[3]
