On Wednesday 23 July 1941 or somewhere around this date, Einsatzcommando 3 murdered 83 Jewish men and 12 Jewish women. Non-Jews killed by the Einsatzcommando: 30. A total of 125 persons died on this location in Kėdainiai.
Source of this record: The so-called Jäger Report (full title: Complete tabulation of executions carried out in the Einsatzkommando 3 zone up to December 1, 1941) was written on 1 December 1941 by Karl Jäger, commander of Einsatzkommando 3 (EK 3), a killing unit of Einsatzgruppe A which was attached to Army Group North during the Operation Barbarossa. It is the most detailed and precise surviving chronicle of the activities of one individual Einsatzkommando, and a key record documenting the Holocaust in Lithuania as well as in Latvia and Belarus.
The photo is most probably not in this area but an example of German execution units and their work.
