Best Generals in US History?

[L Verge]

When military passes were issued, wouldn't they be checked at each point and returned to the bearer in order for that person to pass through other sentry points? Granted that Booth and Herold would have had a much harder time approaching other sentries between Washington and the Confederacy, but I can't imagine that they would relinquish or toss those passes (if they existed) once they cleared the Navy Yard Bridge.

Has anyone ever seen what a U.S. military pass looked like in 1865? Was there a place for a sentry to initial or stamp approval for passage? Would Johnson have issued a personalized pass instead of a standard one?
