Hiwi (volunteer) in the context of "Trawniki men"

During World War II, Trawniki men ([travˈniki]; German: Trawnikimänner) were Eastern European Nazi collaborators, consisting of either volunteers or recruits from prisoner-of-war camps set up by Nazi Germany for Soviet Red Army soldiers captured in the border regions during Operation Barbarossa launched in June 1941. Thousands of these volunteers served in the General Government territory of German-occupied Poland until the end of World War II. Trawnikis belonged to a category of Hiwis (German abbreviation for Hilfswilliger, literally "those willing to help"), Nazi auxiliary forces recruited from native subjects serving in various jobs such as concentration camp guards.

Between September 1941 and September 1942, the German SS and police trained 2,500 Trawniki men known as Hiwi Wachmänner (guards) at the special training camp at Trawniki outside of Lublin; by the end of 1944, 5,082 men were on active duty. Trawnikimänner were organized by Streibel into two SS Sonderdienst battalions. Some 1,000 Hiwis are known to have run away during field operations. Although the majority of Trawniki men or Hiwis came from among the prisoners of war, there were also Volksdeutsche from Eastern Europe among them, valued because of their ability to speak Russian, Ukrainian and other languages of the occupied territories. All the officers at the Trawniki camp were Reichsdeutsche (citizens of the German Reich), and most of the squad commanders were Volksdeutsche (people whose language and culture had German origins but who did not hold German citizenship). The conscripted civilians and former Soviet POWs included Armenians, Azerbaijanis, Belarusians, Estonians, Georgians, Latvians, Lithuanians, Russians, Tatars, and Ukrainians. The Trawnikis took a major part in Operation Reinhard, the Nazi plan to exterminate Jews. They also served at extermination camps and played an important role in the annihilation of the Warsaw Ghetto Uprising (see the Stroop Report), among others.
