In my last post, I mentioned that Robert Renwick had collected the signatures of Baltimore men and Confederates imprisoned at Fort Warren in Boston Harbor. One of the men was none other than our Alexander M. DeBree.
Of the 124 signatures he gathered were the names of Baltimore's mayor, George William Brown and Confederate agents John Mason and James Slidell. Maryland had been placed under martial law by the Lincoln administration for its Southern sympathies. Mason and Slidell had been removed illegally from the British ship Trent, setting off the Trent Affair.
Also there were naval officers, many of whom who had refused to take an Oath of Allegiance to the United States after their vessels returned to port in the North.
Among them were Flag Officer Samuel Barron Sr., Commodores William Ward and Willaim Glassell (a pioneer in submarine warfare).
