In 1920, during the battles against the Bolsheviks and when the Polish troops of General Rydz-Śmigły's Group were stationed, a cemetery was established in Dyneburg for the burial of Polish legionaries who had taken part in the liberation of Latvia from the Bolsheviks. It was located within the Polish civilian cemetery on the so-called "Slobódka". 173 Polish soldiers were buried there (among them 26 with undetermined surnames). In addition to Poles, 69 soldiers of other armies (including Bolshevik prisoners of war), whose names are unknown, were also buried here. Legionaries buried in this cemetery died in battles such as those at Kazul and Grustan in early January 1920. However, later burials of soldiers who died of wounds and illnesses in the city hospital and in field hospitals 101 and 102 predominated. Legionaries who died on 9-10 January 1920 were buried here first, while those who died at the end of April 1920 were buried here last. A small chapel was set up in the cemetery, as well as a simple wooden cross with an inscription on three boards: "1920. TO THE I.-V./ MEMORY/ OF THE FALLEN SOLDIERS IN THE BORDERLANDS FROM THE GROUP/GEN. RYDZ-ŚMIGŁY". In 1921, a branch of the Committee of Brotherly Graves was formed in Dyneburg to look after the graves of Latvian and Polish soldiers. The Committee collected funds for the construction of a monument in honour of Polish soldiers killed in Latvia in 1919-1920, which was solemnly unveiled on 22.06.1928. It was a four-metre-high sarcophagus built of stone blocks, placed on an earth embankment several metres high. In its upper part a slab was placed with the inscription: "TO THE HEROIC POLISH SOLDIERS FALLEN IN THE STRUGGLE FOR THE INDEPENDENCE OF LATVIA/ IN ETERNAL MEMORY". The ceremony was attended by Latvian President Gustavs Zemgals and Prime Minister P. Juraševskis. On the same day, a similar memorial was unveiled in the Lutheran cemetery by the graves of Latvian soldiers. Ceremonies were held at these sites in the interwar period. After the Red Army entered Latvia, the liquidation of the Slobodka cemetery began. The monument was most probably demolished already in 1940. The mound on which this commemoration stood was also destroyed. The Polish cemeteries - civilian and military - were completely levelled during the Soviet era, a sand mine and gravel pit were established here, and when the site was finished, it was used as the city dump. The Polish Association "Promień" (Ray) cleaned up the site in 1990, and two years later a 13-metre high monument-cross by Romuald Gibowski and Wanda Baulina was erected from public collections. In 1999, a ceremony was held to unveil the bronze eagle (funded by the Council for the Protection of Struggle and Martyrdom Sites) placed on the monument. At the foot of the monument lie plaques with the names of the buried legionaries determined in 2014 by the OPWiM Council. The inscriptions include 145 soldiers' names, their military ranks and dates of death. 28 unknown soldiers are also mentioned. The plaques were funded by the OPWiM Council. In 2008, the site of the former war cemetery was surveyed on behalf of the OPWiM Council by a group of archaeologists under the direction of Professor Andrzej Kola by means of archaeological drilling surveys and excavation. As a result of the work, it was assessed that the exploitation of the gravel pit had completely destroyed the existing graves here.
