In front of the main gate of the Ross Cemetery there is a military cemetery, which was established after the war of 1920. Initially, it was the place of eternal rest for Polish officers and volunteers killed in the battles for Vilnius in 1919-1920. In the middle of this necropolis, on a small hill under the cemetery wall, lie the remains of Maria Piłsudska, née Bilewicz, and the heart of her son - the first Marshal of Poland, Józef Piłsudski, who died on 12 May 1935.The funeral of the Marshal's heart and a coffin with his mother's remains took place on 12 May 1936. The cemetery, rebuilt for the occasion according to a design by Prof. Wojciech Jastrzębowski from Kraków, was surrounded by a granite wall with a small chapel of Our Lady of the Dawn Gate at the gate. In September 1939, the bodies of three Polish Army soldiers killed in battles against the Soviets near the cemetery were buried here. In July 1944, further burials took place, burying the bodies of Home Army soldiers killed during Operation "Ostra Brama". After the end of the Second World War and the departure of the majority of Poles from Vilnius, the cemetery deteriorated due to lack of care and due to deliberate devastation, witnessed by the marks left by rifle bullets on some of the soldiers' graves. In 1993, the Council for the Protection of Struggle and Martyrdom Remembrance reconstructed the cemetery, arranging the graves of soldiers killed in 1939 and those of Home Army partisans in a permanent way. These burials were concentrated in 3 rows on either side of the gravestone of Maria Piłsudska and her son, referring in appearance to the soldiers' gravestones of 1920. - They were made in an identical form, only a small emblem of Fighting Poland was placed on the crosses. Later, the OPWiM Council repeatedly carried out renovation works at this cemetery, and in 2009 it buried here the remains of a Home Army soldier, exhumed from the Gulbiny Wielkie estate near Vilnius. Following the liquidation of the OPWiM Council in 2016, the care of the cemetery was taken over by the Ministry of Culture and National Heritage. Currently, 242 soldiers are buried here - 164 soldiers killed in 1919-1920, 3 soldiers killed on 17.09.1939 and 75 partisans of the Home Army.
