What Was The Role of David Herold

[L Verge]

It couldn't have been too dark in front of Seward's house, assuming that the lamp post that Powell tied his horse to was lit. It is also safe to assume that there was more than one street lamp on the Square.

Mr. Kauffman used to claim on the Surratt Booth Tours (when he was a narrator years ago) that Herold was a point man sent to make sure that Powell got into the Seward house to do his duty, then Herold was to check on Atzerodt's status, and then high tail it to the Navy Yard Bridge to catch up with Booth. That sounds reasonable to me.
