Mosby's men in Southern MD., part 2

[Laurie Verge]

We need Messrs. Richter and Smith to comment on the Mosby angle. Wat Bowie is very familiar to anyone who has read about the Civil War in Maryland, but Capt. Hebb is not. Do you know where he was from in Southern Maryland, John?

Also, why had Mosby sent some of his men to winter camp in the Northern Neck of Virginia? Did his timing coincide with Booth arriving in Southern Maryland with his kidnap plans in November of 1864? The timelines here seem eerily linked.
