Helmno, the first death camp, the shocking truth.

please not that as i live in Poland my teachers are well informed on the topic I have choosen. Please do not use alot of parafrazing and i am only allowd 4 sources aquirred from the internet. The rest of sources must be books and articles and or journals. I want to show why this location was choosen eg, geographical, who was involved from the german army and in which way people were murdered. As well i want to touch on the aspect that not only Jews were murdered but as well poles and some Russians. I of course am open to suggestions from you as to what else should be included and how. I hope that this will be helpful.Oh and the font size is 12 .
