The bodies were buried in mass graves in the Katyn forest and they were never supposed to be found. On the 82nd anniversary of the Katyn massacre, the IPN undertook a number of activities to commemorate the victims of this genocide.

The highlight of the celebrations prepared by the IPN was the opening of the "Ostaszków, Post box no. 37" exhibition on 13 April 2022, in the Museum of the Second World War in Gdansk.
