During this year, 1869, when the negotiations in England had been agreed upon, the Canadian Government had sent out a surveying expedition under Lieut.-Colonel Dennis. This officer had taken a prominent part in the affair of the Fenian Raid at Fort Erie three years before, with no advantage to the country and considerable discredit to himself. His party began surveying the land where a hardy population of half-breeds had their farms and homes, and where they had been settled for generations. Naturally great alarm and indignation were aroused. The road that was being built from Winnipeg to the Lake of the Woods also added considerably to their anxiety. The Hudson's Bay officials were mainly covertly hostile. The French priests also viewed an irruption of strangers with strong aversion, and everything tended to incite an uprising against the establishment of the new Government. When Lieut.-Governor Macdougall arrived at Pembina and crossed the boundary line, he was stopped by an armed force of French half breeds, and turned back out of the country. He waited till the 1st December, when his commission was to have come into force, and then appointed Lieut.-Colonel Dennis as Lieutenant and Conservator of the Peace, and sent him to Fort Garry to endeavour to organise a sufficient force among the loyal population to put down the rebellion, and re-establish the Queen's authority. When Lieut.-Colonel Dennis reached Fort Garry, he went straight to Dr. Schultz' house where Mair was staying at the time, and showed them his commission. Schultz, who was an able man of great courage and strength of character, as well as sound judgment, said at once that the commission was all that was wanted, and that he would organise a force of the surveyors, Canadian roadmen, etc., who were principally Ontario men, and that they could easily seize the Fort that night by surprise, as there were only a few of the insurgents in it, and those not anticipating the slightest difficulty. This was the wisest and best course, for had the Fort been seized, it would have dominated the settlement and established a rallying point for the loyal, who formed fifty per cent. of the population. Colonel Dennis would not agree to this. On the contrary he advised Dr. Schultz to organise all the men he could at the Fort Garry Settlement, while he himself would go down to the Stone Fort, and raise the loyal Scotch half breeds of the lower Settlements. This decision at once shut off all possibility of success. Riel, the rebel leader, had ample opportunity not only to fill Fort Garry with French half breeds, but it enabled him to cut off and besiege Dr. Schultz and the Canadians who had gathered at his house for protection.
