The Division was named after the SA or (Sturmabteilung) hero Horst Wessel, a German Nazi known for being the author of lyrics to the song "Die Fahne hoch" (Horst Wessel Lied) and for being glorified by the Nazi regime as a martyr of the early years of the Nazi party.
Upon returning to the Third Reich he was posted to the 18th SS Volunteer Panzergrenadier Division Horst Wessel as a commander from 3 to 10 January 1945.
