Excerpt from Elie Wiesel's Night. One of the most powerful pieces of text I have ever read. 

"The road was endless. To allow oneself to be carried by the mob, to be swept away by blind fate. When the SS were tired, they were replaced. But no one replaced us. Chilled to the bone, our throats parched, famished, out of breath, we pressed on. 

We were the masters of nature, the masters of the world. We had transcended everything - death, fatigue, our natural needs. We were stronger than cold and hunger, stronger than the guns and the desire to die, doomed and rootless, nothing but numbers, we were the only men on earth."
