The so-called Jäger Report, also Jaeger Report (full title: Complete tabulation of executions carried out in the Einsatzkommando 3 zone up to December 1, 1941)[1] 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.[2]
