The Boston sailors had not yet finished their narrative of the two battles, when the thought occurred to some of the adventurous listeners that they might strike a retaliatory blow by capturing the "Margaretta." Therefore, bidding the sailors to say nothing to the British of Lexington and Concord, they left the wharf and dispersed through the town, seeking for recruits. That same evening, sixty stalwart men assembled in a secluded farm-house, and laid their plans for the destruction of the schooner. It was then Saturday night, and the conspirators determined to attack the vessel the next morning while the officers were at church. All were to proceed by twos and threes to the wharf, in order that no suspicion might be aroused. Once at the water-side, they would rush to their boats, and carry the schooner by boarding.
Sunday morning dawned clear, and all seemed propitious for the conspirators. The "Margaretta" had then been in port for more than a week, and her officers had no reason to doubt the loyalty and friendship of the inhabitants: no whisper of the occurrences in Massachusetts, nor any hint of the purposes of the people of Machias, had reached their ears. Therefore, on this peaceful May morning, Capt. Moore donned his full-dress uniform, and with his brother officers proceeded to the little church in the village.
Every thing then seemed favorable to the success of the adventure. The "Margaretta," manned by a sleepy crew, and deserted by her officers, lay within easy distance of the shore. It seemed as though the conspirators had only to divide into two parties; and while the one surrounded the church, and captured the worshipping officers, the others might descend upon the schooner, and easily make themselves masters of all.
But the plot failed. History fails to record just how or why the suspicions of Capt. Moore were aroused. Whether it was that the wary captain noticed the absence of most of the young men of the congregation, or whether he saw the conspirators assembling on the dock, is not known. But certain it is that the good dominie in the pulpit, and the pious people in the pews, were mightily startled by the sudden uprisal of Capt. Moore, who sprang from his seat, and, calling upon his officers to follow him, leaped through the great window of the church, and ran like mad for the shore, followed by the rest of the naval party.
There was no more church for the good people of Machias that morning. Even the preacher came down from his pulpit to stare through his horn-rimmed glasses at the retreating forms of his whilom listeners. And, as he stood in blank amazement at the church door, he saw a large party of the missing young men of his congregation come dashing down the street in hot pursuit of the retreating mariners. In their hands, the pursuers carried sabres, cutlasses, old flint-lock muskets, cumbrous horse-pistols, scythes, and reaping-hooks. The pursued wore no arms; and, as no boat awaited them at the shore, their case looked hopeless indeed. But the old salt left in charge of the schooner was equal to the occasion. The unsabbath-like tumult on the shore quickly attracted his attention, and with unfeigned astonishment he had observed his commander's unseemly egress from the church. But, when the armed band of colonists appeared upon the scene, he ceased to rub his eyes in wonder, and quickly loaded up a swivel gun, with which he let fly, over the heads of his officers, and in dangerous proximity to the advancing colonists. This fire checked the advance of the conspirators; and, while they wavered and hung back, a boat put off from the schooner, and soon took the officers aboard. Then, after firing a few solid shot over the town, merely as an admonition of what might be expected if the hot-headed young men persisted in their violent outbreaks, the "Margaretta" dropped down the bay to a more secluded anchorage.
The defeated conspirators were vastly chagrined at the miscarriage of their plot; but, nothing daunted, they resolved to attempt to carry the schooner by assault, since strategy had failed. Therefore, early the next morning, four young men seized upon a sloop, and, bringing her up to the wharf, cheered lustily. A crowd soon gathered, and the project was explained, and volunteers called for. Thirty-five hardy sailors and woodmen hastily armed themselves with muskets, pitchforks, and axes; and, after taking aboard a small supply of provisions, the sloop dropped down the harbor toward the "Margaretta." The captain of the threatened schooner had observed through his spy-glass the proceedings at the wharf, and suspected his danger. He was utterly ignorant of the reason for this sudden hostility on the part of the people of Machias. He knew nothing of the quarrel that had thus provoked the rebellion of the colonies. Therefore, he sought to avoid a conflict; and, upon the approach of the sloop, he hoisted his anchor, and fled down the bay.
The sloop followed in hot haste. The Yankees crowded forward, and shouted taunts and jeers at their more powerful enemy who thus strove to avoid the conflict. Both vessels were under full sail; and the size of the schooner was beginning to tell, when, in jibing, she carried away her main boom. Nevertheless, she was so far ahead of the sloop that she was able to put into Holmes Bay, and take a spar out of a vessel lying there, before the sloop overtook her. But the delay incident upon changing the spars brought the sloop within range; and Capt. Moore, still anxious to avoid an encounter, cut away his boats, and stood out to sea. With plenty of sea room, and with a spanking breeze on the quarter, the sloop proved to be the better sailer. Moore then prepared for battle, and, as the sloop overhauled him, let fly one of his swivels, following it immediately with his whole broadside, killing one man. The sloop returned the fire with her one piece of ordnance, which was so well aimed as to kill the man at the helm of the "Margaretta," and clear her quarter-deck. The two vessels then closed, and a hand-to-hand battle began, in which muskets, hand-grenades, pikes, pitchforks, and cutlasses were used with deadly effect. The colonists strove to board their enemy, but were repeatedly beaten back. If any had thought that Capt. Moore's continued efforts to avoid a conflict were signs of cowardice, they were quickly undeceived; for that officer fought like a tiger, standing on the quarter-deck rail, cheering on his men, and hurling hand-grenades down upon his assailants, until a shot brought him down. The fall of their captain disheartened the British; and the Americans quickly swarmed over the sides of the "Margaretta," and drove her crew below.
This victory was no mean achievement for the colonists. The "Margaretta" was vastly the superior, both in metal and in the strength of her crew. She was ably officered by trained and courageous seamen; while the Yankees had no leaders save one Jeremiah O'Brien, whom they had elected, by acclamation, captain. That the Americans had so quickly brought their more powerful foe to terms, spoke volumes for their pluck and determination. Nor were they content to rest with the capture of the schooner. Transferring her armament to the sloop, O'Brien set out in search of prizes, and soon fell in with, and captured, two small British cruisers. These he took to Watertown, where the Massachusetts Legislature was then in session. The news of his victory was received with vast enthusiasm; and the Legislature conferred upon him the rank of captain, and ordered him to set out on another cruise, and particularly watch out for British vessels bringing over provisions or munitions of war to the king's troops in America.
But by this time Great Britain was aroused. The king saw all America up in arms against his authority, and he determined to punish the rebellious colonists. A naval expedition was therefore sent against Falmouth, and that unfortunate town was given to the flames. The Legislature of Massachusetts then passed a law granting commissions to privateers, and directing the seizure of British ships. Thereafter the hostilities on the ocean, which had been previously unauthorized and somewhat piratical, had the stamp of legislative authority.
Petty hostilities along the coast were very active during the first few months of the war. The exploits of Capt. O'Brien stirred up seamen from Maine to the Carolinas, and luckless indeed was the British vessel that fell into their clutches. At Providence two armed American vessels re-took a Yankee brig and sloop that had been captured by the British. At Dartmouth a party of soldiers captured a British armed brig. In addition to these exploits, the success of the American privateers, which had got to sea in great numbers, added greatly to the credit of the American cause.
