The soldiers resting here most likely died during the crossing of the Dvina River on 3 January 1920. The graves of 2 or 4 unknown soldiers were located by the river, below the Szachnów manor house. Above the presumed burial place of the soldiers, on the edge of a meadow, the Council for the Protection of Struggle and Martyrdom Sites erected a two-metre-high reinforced concrete legion cross in 1997, modelled on the crosses erected on the graves of soldiers killed in the Polish-Bolshevik war. The cross, at the crossing of the arms, bears a black stone plaque with the inscription in Polish and Latvian: "TO THE MEMORY OF POLISH SOLDIERS / FALLEN IN 1919-1920 / FOR THE INDEPENDENCE OF LATVIA". During the renovation work carried out by the Foundation Helping Poles in the East in 2019, as part of the task subsidised by the programme of the Minister of Culture and National Heritage "Sites of National Remembrance Abroad", a small space at the foot of the monument was paved with cement blocks.
