On 22 August 1941, the Danish parliament adopted the Anti-Communist Act with retroactive effect.[1] On 29 August 1943, during the countrywide Operation Safari, the Germans captured the camp and in the event, 95 prisoners managed to escape, while the remaining 150 communists were subsequently deported to the German Stutthof concentration camp.[4] From around September that year, the German Gestapo began using Horserød to detain various Danish resistance members and Jews. Although Horserød camp was not officially described as a concentration camp, it had the same functions, but unlike the German concentration camps, it was not administered by the SS.[5][2]
