Killing Lincoln - Nat Geo (Reactions)

[RJNorton]

Please forgive...here I go questioning history again. I realize most every Lincoln book ever published includes Tad with the group that walked the streets of Richmond. My question: is there any other source other than William H. Crook for this? Crook's memories on a lot of things, written many years after the fact, have been found to be suspect. Dr. William Hanchett, for example, has studied Crook's reminisces and found they fall into the myth category. Yet it seems all authors accept Crook's account that Tad was with the group. Is there another source that supports Crook's account? Was Crook himself even with the group when they walked through Richmond?
