The Freikorps Danmark (called Frikorps Danmark by the Danes, sometimes listed as SS-Freiwilligen-Verband Dänemark) was founded in 1941 on the request of the Danish Nazi-party (Danmarks Nationalsocialistiske Arbejder Parti (DNSAP)) and with the approval of the Danish government. There were some trouble with recruiting officers until it was decided that they would keep their Danish rank (and pension) when they joined the Waffen-SS. The Danish soldiers swore an oath to the commander of the Wehrmacht and not the usual oath to Adolf Hitler.
Christian Peder Kryssing became the first commander of the unit even though he was not a member (or even supporter) of the DNSAP. Kryssing was soon replaced by pro-Nazi Christian Frederick von Schalburg (who at the time was attached to Wiking division) who finished their training.
Freikorps Danmark was transfered to the Eastern front in May 1942 and were attached to the Totenkopf division. They fought in the savage battles of the Demjansk-pocket and lost 78% of it's manpower (including Christian Frederick von Schalburg and his successor Hans von Lettow-Vorbeck).

Freikorps Danmark was sent back to Denmark in August 1942 on leave. They returned to the Eastern front in October (with Knud Børge-Martinsen as the new commander) and was stationed near Nevel.
The unit was withdraw from the front in March 1943 and sent to the Grafenwöhr camp (near Nuremberg). It was disbanded 20 May and most of the Danes were transfered to SS-Panzergrenadier Regiment 24 Danmark (of the Nordland division).

Known war crimes

According to letters written by Danish volunteers no prisoners were taken after Christian Frederick von Schalburg was killed in action 2 June 1942.
