The very day before the Indians commenced their simultaneous attack on the several posts of the English, the only armed vessel that had been constructed on these upper lakes, serving chiefly as a medium of communication between Detroit and Michilimackinac, had arrived with despatches and letters from the former fort. A well-concerted plan of the savages to seize her in her passage through the narrow waters of the river Sinclair had only been defeated by the vigilance of her commander; but, ever since the breaking out of the war, she had been imprisoned within the limits of the Huron. Laborious indeed was the duty of the devoted crew. Several attempts had been renewed by the Indians to surprise them; but, although their little fleets stole cautiously and noiselessly, at the still hour of midnight, to the spot where, at the last expiring rays of twilight, they had beheld her carelessly anchored, and apparently lulled into security, the subject of their search was never to be met with. No sooner were objects on the shore rendered indistinct to the eye, than the anchor was silently weighed, and, gliding wherever the breeze might choose to carry her, the light bark was made to traverse the lake, with every sail set, until dawn. None, however, were suffered to slumber in the presumed security afforded by this judicious flight. Every man was at his post; and, while a silence so profound was preserved, that the noise of a falling pin might have been heard upon her decks, every thing was in readiness to repel an attack of their enemies, should the vessel, in her course, come accidentally in collision with their pigmy fleets. When morning broke, and no sign of their treacherous foes was visible, the vessel was again anchored, and the majority of the crew suffered to retire to their hammocks, while the few whose turn of duty it chanced to be, kept a vigilant look-out, that, on the slightest appearance of alarm, their slumbering comrades might again be aroused to energy and action. Severe and harassing as had been the duty on board this vessel for many months,--at one moment exposed to the assaults of the savages, at another assailed by the hurricanes that are so prevalent and so dangerous on the American lakes,--the situation of the crew was even less enviable than that of the garrison itself. What chiefly contributed to their disquietude, was the dreadful consciousness that, however their present efforts might secure a temporary safety, the period of their fall was only protracted. A few months more must bring with them all the severity of the winter of those climes, and then, blocked up in a sea of ice,--exposed to all the rigour of cold,--all the miseries of hunger,--what effectual resistance could they oppose to the numerous bands of Indians who, availing themselves of the defenceless position of their enemies, would rush from every quarter to their destruction.
