One misfortune led to another. A few days before Sherbrooke’s arrival at Castine the United States ship “Adams,” a heavy corvette carrying twenty-eight guns, having escaped from Chesapeake Bay and cruised some months at sea struck on a reef on the Isle of Haut, and was brought into the Penobscot in a sinking condition. Captain Morris, who commanded her, took the ship up the river about twenty-five miles, as far as Hampden near Bangor, and removed her guns in order to repair her. Sherbrooke, on occupying Castine, sent a detachment of some six hundred men in boats up the river to destroy the ship, while he occupied Belfast with another regiment.[146] Captain Morris hastily put his guns in battery, and prepared to defend the ship with his crew, numbering probably more than two hundred men, relying on the militia to cover his flanks. On the morning of September 3, in a thick fog, the enemy’s boats approached and landed their infantry, which attacked and routed the militia, and obliged Captain Morris to set fire to the “Adams,” abandon his guns, and disperse his men.[147] The British force then marched to Bangor, which they occupied without opposition. Their entire loss was one man killed and eight wounded.[148] At Bangor they remained nearly a week, destroying vessels and cargoes; but Sir John Sherbrooke had no orders to occupy the country west of the Penobscot, and his troops returned September 9 to Castine. At Castine the British remained, while another detachment occupied Machias. All the province of Maine east of the Penobscot was then in Sherbrooke’s hands. The people formally submitted. One hundred miles of Massachusetts sea-coast passed quietly under the dominion of the King of England. The male citizens were required to take, and took, the oath of allegiance to King George,[149] and showed no unwillingness to remain permanently British subjects. After September 1 the United States government had every reason to expect that Great Britain would require, as one condition of peace, a cession of the eastern and northern portions of Maine. For this purpose the British needed also to occupy Lake Champlain, in order to make their conquests respectable. The British general might move on Plattsburg or on Burlington; but in order to maintain his position he must gain naval possession of the Lake. In such a case the difficulties of the American government would be vastly increased, and the British position would be impregnable. Armstrong knew these circumstances almost as well as they were known to Sir George Prevost.
