From the energy displayed, and the skill shown in seizing the main points in the country, it will be seen that the Montreal merchants were not lacking in ability to plan and decision to execute. The two great forces have now met, and for fifty years a battle royal will be fought for the rivers, rocks, and plains of the North Country. At present it is our duty to follow somewhat further the merchants of Montreal in their agencies in the North-West. There can be no doubt that the competition between the two companies produced disorder and confusion among the Indian tribes. The Indian nature is excitable and suspicious. Rival traders for their own ends played upon the fears and cupidity alike of the simple children of the woods and prairies. They represented their opponents in both cases as unreliable and grasping, and party spirit unknown before showed itself in most violent forms. The feeling against the whites of both parties was aroused by injustices, in some cases fancied, in others real. The Assiniboines, really the northern branch of the fierce Sioux of the prairies, were first to seize the tomahawk. They attacked Poplar Fort on the Assiniboine. After some loss of life, Bruce and Boyer, who were in charge of the fort, decided to desert it. Numerous other attacks were made on the traders' forts, and it looked as if the prairies would be the scene of a general Indian war. The only thing that seems to have prevented so dire a disaster was the appearance of what is ever a dreadful enemy to the poor Indian, the scourge of smallpox. The Assiniboines had gone on a war expedition against the Mandans of the Missouri River, and had carried back the smallpox infection which prevailed among the Mandan lodges. This disease spread over the whole country, and several bands of Indians were completely blotted out. Of one tribe of four hundred lodges, only ten persons remained; the poor survivors, in seeking succour from other bands, carried the disease with them. At the end of 1782 there were only twelve traders who had persevered in their trade on account of the discouragements, but the whole trade was for two or three seasons brought to an end by this disease. The decimation of the tribes, the fear of infection by the traders, and the general awe cast over the country turned the thoughts of the natives away from war, and as Masson says, "the whites had thus escaped the danger which threatened them." Two or three years after the scourge, the merchants of Montreal revived the trade, and, as we shall see, made a combination which, in the thoroughness of its discipline, the energy of its operations, the courage of its promoters, and the scope of its trade, has perhaps never been equalled in the history of trading companies.
