A pedantic point. Treblinka was not a “concentration camp;” it was an extermination facility. It did one thing and one thing only: it exterminated Jews on the day of their arrival. The Germans constructed only 5 such camps, all in Poland: Treblinka, Sobibor, Belzec, Chelmno, and Majdanek. Treblinka was the destination of the Warsaw Ghetto. In the summer of 1942, the Germans liquidated 360,000 residents of the Ghetto in about 60 days in Treblinka, or about 6,000 per day. Treblinka was a little east of Warsaw, just south of the River Bug and Siedlce station — the main line east to Minsk and Smolensk. The only Jews who survived Treblinka were “work Jews,” imprisoned at Treblinka by the Germans to perform tasks in the camp; when the camp closed these Jews were also killed. Just as at Sobibor, the work Jews contrived a break-out near the end of the camp’s life, and some did escape and survive the war (a very small number, less than 10). Treblinka’s commandant, Franz Stangl, was extradited from Brazil in 1970 and tried in Germany. He died in prison from a heart attack. He was the only extermination camp commandant who was ever brought to justice. It is estimated that 800,000 to 1,200,000 Jews were exterminated at Treblinka in less than a year of operation.
