Four soldiers of the UBK (UBK) hit-and-run battalions, operating within the structures of the Home Army, were killed on 7 May 1944 when they were surprised by the Lithuanian Plechavičius unit (which had collaborated with the Germans in fighting against the Soviets and Poles), stationed in nearby Nemenchyn. After the action in Verkiai, the UBK detachment proceeded towards Jęczmieniszki and Sużany. Near the village of Borunele it was ambushed. The betrayal that led to the clash was allegedly perpetrated by a Lithuanian priest, who was drawing up lists of Poles to be deported for labour in Germany. Mostly Polish patriotic youths were included on the lists. The dead were buried in the village cemetery in Borunelia. Initially, the dead were buried only in sheets. It was not until several months later that the bodies were exhumed for identification and dignified burial. Then the corpses, wrapped in sheets, were placed in coffins and buried in the same order in which they had been exhumed. Nameless birch crosses were placed on the graves. Later, someone replaced these crosses with metal ones (these have survived to the present day). At an unknown time, a monument was erected here, bearing only the date - 7 May 1944.In 2002. Stanisław Bortkiewicz placed a high wooden cross next to the existing ones.The grave is situated on a hill, accessible by steps with a railing, surrounded by a concrete kerb on which a metal fence has been placed. On the grave there is a vertical concrete slab with a black cross with the figure of Christ and the date "1944 V 7". On either side of the cross are fixed two plaques of light marble with the inscriptions: "Here rest the soldiers of the 1st Wileńska Brigade of the AK "Juranda" Czesław Grombczewski: Mieczysław Jarmułowicz 'Szerszeń', Stanisław Kulesza 'Eskula', Jerzy Rodziewicz 'Jurek'" (left plaque) and "Soldiers of the shock cadre battalion from Warsaw: NN "Belgrade", NN "Poltava" / Honour their memory / Consulate General of the Republic of Poland in Vilnius, Veterans' Magazine of Radio znad Wilii, 11 XI 2007" (right plaque).Behind the fence of the grave is a tall wooden cross with a shrine to the Virgin Mary, a few steps behind it - 4 tall metal crosses.
