A few metres away from the Polish quarters and the Lithuanian quarters, where soldiers killed in 1920 are buried, a single grave of a Polish soldier from the same period has been preserved. An inscription in Lithuanian is engraved on the concrete cross: "A+A Lenku karininkas M. Jasinskas + 1920" [translated into Polish: "Ś.P. oficer polski M. Jasiński"]. It has been established that Jasinski Marian, a private of the 31st pp, killed on 28 May 1920, is buried here.

This grave, for an unknown reason, was not renovated during the renovation of the Polish quarters carried out in 2020 by the National Remembrance Foundation.
