SS Heimwehr "Danzig" was an SS unit established in the Free City of Danzig (today Gdańsk and environs, Poland) before the Second World War. It fought with the German Army against the Polish Army during the invasion of Poland, and some of its members committed a massacre of Polish civilians. After this it became part of the 3rd SS Totenkopf Division and ceased to exist as an independent unit. Also known as Heimwehr Danzig (Danzig Home Defense), it was officially established on 20 June 1939, when the Danzig senate under Albert Forster decided to set up its own armed force; a cadre of this new unit primarily formed the Danzig SS Wachsturmbann "Eimann". History Reichsführer-SS Heinrich Himmler supported this project and sent SS-Obersturmbannführer Hans Friedemann Götze to Danzig. Goetze was the commander of the III. Sturmbann (Battalion) of the 4th SS-Totenkopfstandarte "Ostmark," established in October 1938 in Berlin-Adlersheim. The III. Sturmbann was strengthened with the help of anti-tank defense forces (the Panzerabwehr-Lehrsturm of the SS- Totenkopfstandarten) as well as about 500 additional volunteers from Danzig who named their new unit SS Sturmbann "Goetze". It was formed to conduct police actions in and around Danzig. The Danzig SS-men had been members a special SS troop established in July 1939 - the Wachsturmbann "Eimann" - and at the beginning of August this self-named Sturmbann "Goetze" reached the peninsula at the mouth of the Vistula called the Danzig Westerplatte. There it hid on German ships, including the naval training ship . The Volksdeutsche (ethnic Germans) in Danzig founded the 1,550-man strong Heimwehr Danzig (Danzig Militia). On 1 September 1939, German troops attacked Poland. The Heimwehr Danzig took part under German Army command and in the process captured the Polish post office after fifteen hours; an event which Günter Grass dedicated a chapter of his novel The Tin Drum to. During the attacks, the German forces used ADGZ armoured cars, 75mm and 105mm artillery and flamethrowers against Polish forces armed with pistols, rifles, light machine guns and grenades. The SS-Heimwehr Danzig participated in the attack on the Danzig Westerplatte, and already was considered a part of the 3rd SS Totenkopf Division then forming under Theodor Eicke. Later, it provided coast guard services in Danzig. On 8 September members of the SS Heimwehr Danzig killed 33 Polish civilians in the village of Książki. Other such militias were also involved in war crimes perpetrated on Polish
