When the raiders left the port area on June 27, they proceeded to the federal wharf. Having the advantage of surprise, the crew seized a cutter belonging to the Revenue Service, the USRC "Caleb Cushing" (named for a Massachusetts congressman, United States Attorney General and Minister to Spain). Their original intent was to seize the side wheel steamer "Chesapeake", but its boilers were cold. As they would lose too much time in getting the steam up, they took "Cushing". They escaped and sailed out to sea.
