Following a summer during which Captain David Porter and USS Essex captured a dozen British whaling ships in the eastern Pacific, Porter sailed west to continue his work destroying British commerce. Additionally, Essex had been at sea for nearly a year and needed caulking, and her copper bottom was wearing off and required repairs. Perhaps more importantly, the ship's hold was infested with rats, who destroyed the provisions, and Essex could not remain at sea much longer unless the rats were smoked out.

The longest cruise of a United States Navy ship during the War of 1812 and the one most financially damaging to the British occurred in the Pacific Ocean. It was the result of a bold captain who saw the opportunity to strike at the heart of the British whaling industry and, by doing so, harm the British economy and help drive Great Britain to the bargaining table.

There were many memorable battles during the War of 1812 that have become part of the American legend; Perry's great naval victory on Lake Erie and Jackson's coup de grace at the Battle of New Orleans immediately come to mind. But one of the more compelling stories of the war was an engagement between USS Chesapeake and HMS Shannon, a single-ship duel fought roughly twenty miles northeast of Boston near Cape Ann in the late spring of 1813. Known as the Battle of Boston Harbor, it was fought by two courageous Captains with a spirit of chivalry for the glory of their country.
