It was during the midnight watch, late in September, 1763, that the English garrison of Detroit, in North America, was thrown into the utmost consternation by the sudden and mysterious introduction of a stranger within its walls. The circumstance at this moment was particularly remarkable; for the period was so fearful and pregnant with events of danger, the fort being assailed on every side by a powerful and vindictive foe, that a caution and vigilance of no common kind were unceasingly exercised by the prudent governor for the safety of those committed to his charge. A long series of hostilities had been pursued by the North-American Indians against the subjects of England, within the few years that had succeeded to the final subjection of the Canadas to her victorious arms; and many and sanguinary were the conflicts in which the devoted soldiery were made to succumb to the cunning and numbers of their savage enemies. In those lone regions, both officers and men, in their respective ranks, were, by a communionship of suffering, isolation, and peculiarity of duty, drawn towards each other with feelings of almost fraternal affection; and the fates of those who fell were lamented with sincerity of soul, and avenged, when opportunity offered, with a determination prompted equally by indignation and despair. This sentiment of union, existing even between men and officers of different corps, was, with occasional exceptions, of course doubly strengthened among those who fought under the same colours, and acknowledged the same head; and, as it often happened in Canada, during this interesting period, that a single regiment was distributed into two or three fortresses, each so far removed from the other that communication could with the utmost facility be cut off, the anxiety and uncertainty of these detachments became proportioned to the danger with which they knew themselves to be more immediately beset. The garrison of Detroit, at the date above named, consisted of a third of the ---- regiment, the remainder of which occupied the forts of Michilimackinac and Niagara, and to each division of this regiment was attached an officer's command of artillery. It is true that no immediate overt act of hostility had for some time been perpetrated by the Indians, who were assembled in force around the former garrison; but the experienced officer to whom the command had been intrusted was too sensible of the craftiness of the surrounding hordes to be deceived, by any outward semblance of amity, into neglect of those measures of precaution which were so indispensable to the surety of his trust.
