Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000. In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans, although the partisan movements did not always welcome them. An estimated 20,000 to 30,000 joined the Soviet partisan movement. One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers. Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[r]
Immediately upon arriving at Dachau, the process of dehumanizing prisoners began. Men and women were stripped of all possessions including their clothes which were replaced with striped uniforms. Their hair was shaved and they were given an identification number with a colored triangle to show their category.13 Dachau was a labor camp, most of the many sub-camps of Dachau were built with slave labor. The Nazis exploited the cheap labor by hiring out prisoners to private firms. Prisoners never received their wages, as the private firms paid the Nazis directly for the labor. The work was often heavy labor and the weakened and malnourished prisoners were given little food and lived in unsanitary conditions.
Bergen-Belsen [ˈbɛʁɡn̩.bɛlsn̩], or Belsen, was a Nazi concentration camp in what is today Lower Saxony in northern Germany, southwest of the town of Bergen near Celle. Originally established as a prisoner of war camp, in 1943, parts of it became a concentration camp. Initially this was an "exchange camp", where Jewish hostages were held with the intention of exchanging them for German prisoners of war held overseas. The camp was later expanded to accommodate Jews from other concentration camps.
