These stockade forts were never, at any one period, nearer to each other than from one hundred and fifty to two hundred miles, so that, in the event of surprise or alarm, there was little prospect of obtaining assistance from without.  Each garrison, therefore, was almost wholly dependent on its own resources; and, when surrounded unexpectedly by numerous bands of hostile Indians, had no other alternative than to hold out to the death.  Capitulation was out of the question; for, although the wile and artifice of the natives might induce them to promise mercy, the moment their enemies were in their power promises and treaties were alike broken, and indiscriminate massacre ensued.  Communication by water was, except during a period of profound peace, almost impracticable; for, although of late years the lakes of Canada have been covered with vessels of war, many of them, as we have already remarked, of vast magnitude, and been the theatres of conflicts that would not have disgraced the salt waters of ocean itself, at the period to which our story refers the flag of England was seen to wave only on the solitary mast of some ill-armed and ill-manned gunboat, employed rather for the purpose of conveying despatches from fort to fort, than with any serious view to acts either of aggression or defence.

In proportion as the colonies of America, now the United States, pushed their course of civilisation westward, in the same degree did the numerous tribes of Indians, who had hitherto dwelt more seaward, retire upon those of their own countrymen, who, buried in vast and impenetrable forests, had seldom yet seen the face of the European stranger; so that, in the end, all the more central parts of those stupendous wilds became doubly peopled.  Hitherto, however, that civilisation had not been carried beyond the state of New York; and all those countries which have, since the American revolution, been added to the Union under the names of Kentucky, Ohio, Missouri, Michigan, &c., were, at the period embraced by our story, inhospitable and unproductive woods, subject only to the dominion of the native, and as yet unshorn by the axe of the cultivator.  A few portions only of the opposite shores of Michigan were occupied by emigrants from the Canadas, who, finding no one to oppose or molest them, selected the most fertile spots along the banks of the river; and of the existence of these infant settlements, the English colonists, who had never ventured so far, were not even aware until after the conquest of Canada by the mother-country.  This particular district was the centre around which the numerous warriors, who had been driven westward by the colonists, had finally assembled; and rude villages and encampments rose far and near for a circuit of many miles around this infant settlement and fort of the Canadians, to both of which they had given the name of Detroit, after the river on whose elevated banks they stood.  Proceeding westward from this point, and along the tract of country that diverged from the banks of the Lakes Huron, Sinclair, and Michigan, all traces of that partial civilisation were again lost in impervious wilds, tenanted only by the fiercest of the Indian tribes, whose homes were principally along the banks of that greatest of American waters, the Lake Superior, and in the country surrounding the isolated fort of Michilimackinac, the last and most remote of the European fortresses in Canada.
