With this coffin necessarily others were removed, and one was favored with an inscription which betrayed, we may assume, either native simplicity or British sarcasm. It read: “Here lies the body of John, aged fifty years, a faithful soldier and a Desperate Good Gardner”!
It does not appear that the force quartered on the island was engaged in the first two battles of the Revolution. The commandant of the castle had been sent in February, 1776, to seize powder and other military stores at Salem; but he was delayed at the ferry by the militia until the objects of the depredation had been moved beyond his reach. He returned peaceably to the island. The same officer was ordered from Castle William at this time with five hundred men to draw the Americans, by a false attack, from their posts at Roxbury. The attack did not succeed and the burning of five or six houses in Dorchester was the only result.
In the meantime a formidable force of Americans was concentrated in the vicinity of Boston under Washington; so General Howe, the successor of General Gage, evacuated the town March 17, and the British fleet dropped below the Castle. The embarkation had been a scene of confusion and distress, it being the 27th of March before the transports were able to put to sea. At their departure the British troops threw into the water iron balls and shot, broke off the trunnions of the ordnance given to Castle William in 1740, destroyed the military stores and battery apparatus which they could not take with them and finally blew up the citadel, leaving the island a mass of ruins. Part of the British fleet lay in the lower harbor until June, when it was harassed by American troops under General Lincoln and raised the blockade of Boston Harbor after the exact duration of two years. With the British troops the seat of the war was removed from Massachusetts, and Castle Island was thenceforth, unmolested, in American possession.
Colonel John Turnbull was the officer sent by General Washington to take possession of the island after the evacuation. Lieutenant Colonel Paul Revere was stationed on the island from 1777 to 1779.
At the conclusion of the Revolution it was enacted by the legislature of Massachusetts that all criminals of the State under sentence of confinement should be removed to Castle Island. Pursuant to this law convicts were sent to the island, and though their number never exceeded ninety their audacity taxed the vigilance of the garrison; they made several bold, fruitless efforts to escape, and in their mutinies some were killed and some wounded. Others met their death while endeavoring to form subterranean passages. Stephen Burroughs, whose extensive forgeries gave him great notoriety, here learned the art of a nailer, and in his published memoirs has publicly boasted of his Castle Island exploits.
