i have more to add: germany was officially in poland since september 1 1939.  war ended september 2 1945. that's roughly 6 years if we just skip the details.  in 6 years germany somehow managed to find, capture, transport all these jews to the camps. while simultaneously being busy fighting on both fronts, and officially losing eastern front to soviets in late 1944.  but even if we assume germany was still in control of whole territory on which camps were and kept capturing jews.  and capture along with transport was just 1 hour to any camp. we can calculate that 6 years is 2190 days if we keep classic 365 year frame. which give us 2740 captured and transported prisoners per day.
