Give Me Liberty or Give me Death

I have heard the quote "Give me Liberty or Give me Death" many times over the course of my school career but tonight was the first time i found out there was a document behind it! The author Patrick Henry has an incredibly strong voice in this letter, written to a president (I was confused on this part, on which president he is referring to). This letter, obviously talks about how Henry beleives that now is the time for their liberty to be taken, and that to do so they must fight for it. He refers to "us" and "ourselves" a lot in this letter, so i suppose he believes he is the voice of the people.
