I found a website that contains many letters from Holocaust survivors. I plan to use some of those letters as primary sources and to get quotes. An example of an exerpt from a letter is:
"My Dear Parents!
If only the sky were paper and the world ink, I wouldn’t be capable of describing to you my suffering and all that I see around me.
The camp is situated in a forest clearing. Already early in the morning they take us out to work in the forest. The soles of my feet are bleeding, because they took my shoes from me. We work all day, with hardly any food, and at night we sleep on the ground (they also took our coats from us). Every night drunken soldiers come and beat us with wooden sticks, and my body is already black from bloodstains under the skin and it looks like a piece of charred wood. Sometimes they toss us some uncooked carrots, or beets, and this is shameful and disgraceful: here fists fly in order to grab a little piece or a small leaf. The day before yesterday two boys escaped, so they lined us up in a row, and every fifth one in the line was shot to death. I was not the fifth but I know that I will not leave here alive. I part from you, dear Mother, dear Father, dear brothers, and I cry…"
I feel quotes like these will help present the severity of the Holocaust and hardships victims had to suffer through. I also want to look into similar letters from all of the different groups.
