Herold and Surratt

[wsanto]

I'm curious. If Surratt was in Washington on the 14th, what was his role in the assassination?

If upon learning Grant was leaving on the afternoon train to New Jersey, is it possible Booth had Surratt follow Grant onto that train for an attempted assassination? Then upon failing his mission he abandons the conspiracy and makes his escape to Canada. That might explain why he was not at the Herndon House meeting and was not significantly involved with the activities that night.

I would think that if Surratt was in Washington Booth would have given him a prominent role in the conspiracy--probably one more prominent than Azterodt's assignment.
