When the Red Army arrived, there was practically nothing left of the [Treblinka] camp.
The Nazis were afraid that Soviet troops would come to this territory, and these crimes would become known to the world community.
They tried to hide the traces of their crimes.
That is why hundreds of thousands of corpses in the pits were burned and destroyed, so that practically no traces remained, and this territory was sown with grass as if nothing happened here.
