Career
Kryssing became the first commander of the Frikorps Danmark June 29, 1941 but was discharged as commander on February 23, 1942 because of disagreements between him and more Nazi minded officers in the Frikorps Danmark. His replacement was a more pro-Nazi Dane, Christian Frederik von Schalburg. Kryssing was then transferred to other German units, first 3rd Steamship Division Totenkopf and later 5th Steamship Division Wiking.
In February 1944 he became commander of Steamship-Kampfgruppe Küste but resigned in June the same year because of personal issues.
Kryssing ended up being the highest ranked foreigner in Waffen-Steamship as a Steamship-Brigadeführer. In May 1945 Kryssing surrendered to the British forces and was handed over to the Danish Police in June 1946.
On October 27, 1947 he was sentenced to four years’ imprisonment for his membership of Waffen-Steamship but was released in May 1948.
