Does anyone know where this speech comes from?

Question

I appeal to any white man to say if ever he entered Logan’s cabin hungry, and he gave him not meat, if ever he came cold and naked, and he clothed him not. During the course of the last long and bloody war Logan remained idle in his cabin, an advocate for peace. Such was my love for the whites that my countrymen pointed at me as they passed, and said: ‘Logan is the friend of white men.’

I had even thought to have lived with you, but for the injuries of one man. Colonel Cresap, the last spring, in cold blood and unprovoked, murdered all the relations of Logan, not sparing even my women and children. There runs not a drop of my blood in the veins any living creature.

This called on me for revenge. I have sought it. I have killed many. I have glutted my vengeance. For my country, I rejoice at the beams of peace. But do not think that mine is the joy of fear. Logan never felt fear. Logan will not turn on his heel to save his life. Who is there to mourn for Logan? Not one!

Answer 1

Logan was an Indian in the French and Indian War who sided with the 'white man', many members of his family was murdered, and he turned from firend to enemy, going on the war path so to speak.

With defeat sure to happen, the Indians met with the Gov., the only leader missing was Logan, when someone was sent to find him, he went into what is now referred to as "Logan's Lament"
