From the west the expedition was under Cuthbert Grant, and he, appealing to his fellow Metis, raised the standard of the Bois Brûlés and called his followers the "New Nation." Early in March the Bois Brûlés' leader wrote to Trader J. D. Cameron, detailing his plans and expectations. We quote from his letter: "I am now safe and sound, thank God, for I believe that it is more than Colin Robertson, or any of his suite, dare offer the least insult to any of the Bois Brûlés, although Robertson made use of some expressions which I hope he will swallow in the spring. He shall see that it is neither fifteen, thirty, nor fifty of his best horsemen that can make the Bois Brûlés bow to him. Our people at Fort Des Prairies and English River are all to be here in the spring. It is hoped that we shall come off with flying colours, and _never to see any of them again in the colonizing way in Red River_.... We are to remain at the Forks to pass the summer, for fear they should play us the same trick as last summer of coming back; but they shall receive a warm reception." The details of this western expedition are well given by Lieutenant Pierre Chrysologue Pambrun, an officer of the Canadian Voltigeurs, a regiment which had distinguished itself in the late war against the United States. Pambrun had entered the service of the Hudson's Bay Company as a trader, and been sent to the Qu'Appelle district. Having gone west to Qu'Appelle, he left that western post with five boat loads of pemmican and furs to descend the Assiniboine River to the Forks. Early in May, near the Grand Rapids, Pambrun and his party touched the shore of the river, when they were immediately surrounded by a party of Bois Brûlés and their boats and cargoes were all seized by their assailants. The pemmican was landed and the boats taken across the river. The unfortunate Pambrun was for five days kept in durance vile by Cuthbert Grant and Peter Pangman, who headed the attacking party, and the prisoner was carried back to Qu'Appelle. While Pambrun was here as prisoner, he was frequently told by Cuthbert Grant that the half-breeds were intending in the summer to destroy the Red River settlements; their leader often reminded the Bois Brûlés of this, and they frequently sang their war songs to waken ardour for the expeditions. Captors and prisoner shortly afterward left the western fort and went down the river to Grand Rapids. Here the captured pemmican was re-embarked and the journey was resumed. Near the forks of the Qu'Appelle River a band of Indians was encamped. The Indians were summoned to meet Commander Macdonell, who spoke to them in French, though Pangman interpreted.
