The Ostashkov camp, as one of the three NKVD special camps (the others being Kozelsk and Starobelsk), was a place of confinement for Polish officers, policemen and representatives of other uniformed services who were murdered in the spring of 1940 as part of the Katyn Massacre. Due to the very poor living conditions, some of the prisoners of war died even before the NKVD took the action of 'unloading' the camps. Documents made available by the General Prosecutor's Office of Russia list the names of 46 Poles who died in the Ostashkov camp before its liquidation. Those who died in Ostashkov were buried in the cemetery in the village of Trojeruchitsa, located in the immediate vicinity of Ostashkov. Some may have been buried in another cemetery nearby. The locations of all the Poles' graves have not been pinpointed, so in the 1990s a symbolic commemorative plaque with a cross was erected on one of the surviving Poles' graves, bearing the names of 41 Polish officers who died in the Ostashkov camp. For unexplained reasons, five names, known from the Russian list, were not included on the plaque. In 2013. The Council for the Protection of Remembrance of Struggle and Martyrdom redecorated the site by erecting a granite cross and two plaques on either side of it. The plaques bear the names of 43 Poles (2 more than on the previous commemoration), and the main inscription reads: "To the memory of Polish Army soldiers / State Police officers / Prison guards, gendarmerie / who died in the NKVD POW camp / in Ostashkov in 1939-40 / the Government of the Republic of Poland / the Council for the Protection of Remembrance of Struggle and Martyrdom".
