How did they use the crematories during the Holocaust?

the crematoriums were used to get rid of the dead bodies that were in the gas chambers so they could be refilled. and to also get rid of any one that dided of starvation, desies, or were shot.

I imagine anything prisoners of any other time used.ink, lead, chalk, blood, mud onto the ground, wood, paper, clothing, tattoos, rocks

I think It was Generally the Thomson machine Gun they Used

The Holocaust had no influence on language, people used the same language as they did before.

Yes they used riding crops if they weren't satisfied by what the prisoners were doing. Or if they just felt like it.
