In a letter to Union Major General Winfield Scott Hancock.

"I met Armistead just under the crest of the hill, being carried to the rear by several privates. I ordered them back, but they replied that they had an important prisoner and they designated him as General Longstreet... I dismounted my horse and inquired of the prisoner his name he replied General Armistead of the Confederate Army. Observing that his suffering was very great I said to him, General, I am Captain Bingham of General Hancock's staff, and if you have anything valuable in your possession which you desire taken care of, I will take care of it for you. He then asked me if it was General Winfield S. Hancock and upon my replying in the affirmative, he informed me that you were an old an valued friend of his and he desired for me to say to you, "Tell General Hancock for me that I have done him and done you all an injury which I shall regret or repent (I forget the exact word) the longest day I live." I then obtained his spurs, watch chain, seal and pocketbook. I told the men to take him to the rear to one of the hospitals."
