Holocaust question? I really need help!?

Okay, So I am doing an essay on the ending of the Holocaust, like how it ended. I need to know which last camps were liberated, who liberated them, and how Hitler died. I NEED ALL THIS INFO BY THE 27 OF OCTOBER. Thanks for helping! (I would also appreciate it if somebody could please give their opinion on how the Holocaust and its survivors have actually contributed to our world today.) =) Thanks sooooooo much!
