Chesapeake Bay became the principal scene of their operations; it was there that their main body collected, and their greatest efforts were made. In it a number of line-of-battle ships, frigates, sloops, and cutters had been collected, and early in the season Admiral Sir John Warren and Rear Admiral Cockburn arrived to take command. The latter made numerous descents on the coast, and frequently came into contact with the local militia, who generally fled after a couple of volleys. These expeditions did not accomplish much, beyond burning the houses and driving off the live-stock of the farmers along shore, and destroying a few small towns--one of them, Hampton, being sacked with revolting brutality.
