From his Province House headquarters, Gage awaited reinforcements and braced against a rebel assault. Regiments built several small batteries on the Common and a larger redoubt on Beacon Hill. Gunners at Boston Neck were ordered to keep lighted matches by their cannons at all times. Regulars patrolled the wharves every half hour. Loyalist volunteers with white cockades in their hats kept vigil in the streets at night. “We are threatened with great multitudes,” Gage wrote Lord Dartmouth in mid-May. “The people called friends of government are few.” News from the other provinces was bleak. Connecticut, Rhode Island, and New Hampshire were “in open rebellion,” he told London. “They are arming at New York and, as we are told, in Philadelphia and all the southern provinces.” The royal mail was no longer secure; a postal rider with official correspondence from New York had been detained, his locked bag jimmied open with hammer and pliers.
Guard boat crews patrolled the harbor with 6-pounders, alert for fire rafts and often ducking sniper rounds from the far shore. Ships from England no sooner dropped anchor than potshots rang out. “The country is all in arms, and we are absolutely invested with many thousand men, some of them so daring as to come very near our outposts,” Captain Glanville Evelyn wrote his father in Scotland. Morale sank in the regular ranks. A Royal Navy surgeon permitted to treat wounded British captives in Cambridge wrote in May that the rebel army “is truly nothing but a drunken, canting, lying, praying, hypocritical rabble, without order, subjection, discipline, or cleanliness.” A new British drinking song warned:
Boston we shall in ashes lay,
It is a nest of knaves,
We’ll make them soon for mercy pray,
Or send them to their graves.
There would be ashes on May 17. That night, a sergeant in the 65th Regiment reportedly delivered musket cartridges by candlelight to the barracks on Treat’s Wharf; soon after his arrival, a small, accidental blaze grew into a conflagration that burned until three a.m. Gage had placed the town’s fire engines under military control, and inept redcoats, one merchant complained, operated the apparatus “with such stupidity that the flames raged with incredible fury & destroyed 30 stores.” The losses at Dock Square also included regimental uniforms, weapons, and donations collected for Boston’s poor.
Fresh meat for British larders and forage for British horses could be found within a mile or two of Province House, but trouble could be found there as well. In Boston Harbor, more than thirty islands—used for over a century as livestock pastures and hay fields—stippled the narrow, twisting approaches from open water. Shoals, mudflats, salt creeks, and sandbars changed shape with each new tide. Much of the harbor at low water was no deeper than three fathoms—eighteen feet—while the three largest Royal Navy ships on station drew twenty feet or more. American mariners skittered through this watery terrain in smacks, canoes, and whaleboats, trading shots at long range with British foraging parties. On May 21, Gage sent several sloops to Grape Island, but they scavenged only eight tons of hay before rebels burned eighty more.
On Saturday morning, May 27, six hundred Massachusetts and New Hampshire militiamen scuffed from the Chelsea meetinghouse down Beach Road to the shoreline. By eleven a.m., the ebbing tide had fallen enough to let them slosh knee-deep across narrow Belle Isle Creek to Hog Island, where, as ordered by the Committee of Safety, they rounded up 411 sheep, 27 cows, and 6 horses, shooting those that would not be herded. The British were to get none. Thirty men waded across Crooked Creek to adjacent Noddle’s Island, at the confluence of the Charles and Mystic Rivers. At seven hundred acres, Noddle’s was the largest of the harbor isles, once a refuge for Baptist apostates driven from Boston by Puritans, and long a favorite dueling ground for aggrieved parties of all denominations. Here the rebels set fire to a barn piled high with salt hay.
Aboard the fifty-gun Preston in the Boston anchorage, the sight of thick smoke to the east caught the squinting eye of Samuel Graves, commander of the North American station. Graves this very week had received news from London of his promotion to vice admiral of the white; he celebrated with a thirteen-gun salute from his squadron and colors appropriate to his new rank hoisted above Preston’s deck. A sixty-two-year-old sea dog who had never held high command before arriving in America a year earlier, Graves was a harbor admiral; recovering from a small stroke, he had shuttled between his flagship and a comfortable house on Pearl Street without once in nineteen months venturing out past the Boston lighthouse. His talents were modest—the new promotion notwithstanding—and his grievances many. With thirty vessels in his squadron, but only four substantial ships of force, he was to ensure that Britannia ruled the waves along an eighteen-hundred-mile littoral, from the Gulf of St. Lawrence to Cape Florida. Despite a stupendous increase in smuggling by American insurgents, he admitted that during this past winter “no seizures of any consequence have been made.”
Graves badgered the Admiralty with legitimate complaints about “properly guarding this extensive coast with the few vessels I have”; about the poor condition of those vessels—Hope was “very leaky,” and so were Halifax, Somerset, and others; about the difficulty of getting guns, pilots, provisions, and proper sailors; and about idiotic orders from home, including a directive to search the ballast of every ship arriving in North America for smuggled musket flints, as if ample flint could not be found in American rock. He also complained about General Gage, whom he detested and who detested him in return. With four nephews at sea in the king’s service, Graves was a master of nepotism; Lord North’s undersecretary, William Eden, would describe him this year as “a corrupt admiral without any shadow of capacity.” He was suspected, among other indiscretions, of selling stringy mutton on the Boston black market. Captain Evelyn spoke for many in asserting that “every man both in the army and navy wishes him recalled.”
Graves loathed “rebellious fanatics,” and in that smoke billowing from Noddle’s Island he spied a chance to show General Gage how they should be fought. At three p.m., a detachment of 170 marines from Glasgow, Cerberus, and Somerset landed on the island’s western flank. At the same time, the Diana, a new 120-ton armed schooner just that morning back from chasing gunrunners in Maine under the command of Lieutenant Thomas Graves—from the quartet of nephews—worked her way into Chelsea Creek, which separated the mainland from Noddle’s and Hog Islands. More marines followed Diana in a dozen longboats to cut off the rebel retreat. The pop of militia muskets now sounded from behind stone walls around the Winnisimet ferry landing. Diana answered with grapeshot and bore down on rebel drovers herding livestock through the shallows and onto Beach Road. Fifteen militiamen squatted in a Noddle’s marsh as a rear guard, swapping volleys with the regulars. “The bullets flew very thick,” Corporal Amos Farnsworth of Groton reported. “The balls sung like bees round our heads.” From the Cerberus quarterdeck, marines manhandled a pair of 3-pounders ashore and from a sandy embankment shelled the ferry landing.
Spattered with fire from both flanks, Lieutenant Graves decided that Diana had gone far enough. But as he sought to come about, the wind died. Longboats nosed alongside
