To Fort William, then, with the prospect of meeting several hundreds of the desperate men of the North-West Company, Lord Selkirk made his way. So confident was he in the rectitude of his purpose and in the justice of his cause, that he pushed forward, and without the slightest hesitation encamped upon the Kaministiquia, on the south side of the river, in sight of Fort William. The expedition arrived on August 12th. A demand was at once made on the officers of the North-West Company for the release of a number of persons who had been captured at Red River after the destruction of the colony and been brought to Fort William. The Nor'-Westers denied having arrested these persons, and to give colour to this assertion immediately sent them over to Lord Selkirk's encampment. On the 13th and following days of the month of August, the depositions of a number of persons were taken before his Lordship as a justice of the peace. The depositions related to the guilt of the several Nor'-Wester partners, their destroying the settlement, entering and removing property from Fort Douglas, and the like; and were made by Pambrun, Lavigne, Nolin, Blondeau, Brisbois, and others. It was made so clear to Lord Selkirk that the partners were guilty of inciting the attacks on the colony and of approving the outrages committed, that he determined to arrest a number of the leaders. This was done by regular process--by warrants served on Mr. McGillivray, Kenneth McKenzie, Simon Fraser, and others, but these prisoners were allowed to remain in Fort William. In one case, that of a partner named John McDonald, resistance having been offered, the constables called for the aid of a party of the De Meurons, who had crossed over from the encampment with them in their boats. The leaving of the prisoners with their liberty in Fort William, however, gave the opportunity for conspiracy; and it was represented to Lord Selkirk that Fort William would be used for the purposes of resistance, and that the prisoners arrested would be released. The facts leading to this belief were that a canoe, laden with arms, had left the fort at night; that eight barrels of gunpowder had been secreted in a thicket, and that these had been taken from the magazine; while some forty stand of arms, fresh-loaded, had been found in a barn among some hay. These indications proved that an attempt was about to be made to resist the execution of the law, and accordingly the prisoners were placed in one building and closely guarded, while Lord Selkirk's encampment was removed across the river and pitched in front of the fort to prevent any surprise.
