During the North-West rebellion of 1885 both territorial and federal officials requested Lacombe to visit the Cree and Blackfoot and persuade them not to support Louis Riel. Lacombe travelled to the Blackfoot Indian Reserve, whose residents seemed disinclined to take up arms alongside their old enemies, and then hurried north to call for peace on the Cree reserves near the Battle River. When the hostilities were over he made recommendations to remedy Indian grievances and was asked by Ottawa to investigate matters concerning Indians. To reward those chiefs who had remained loyal during the uprising, the government invited them to visit eastern Canada. Lacombe organized the trip in 1886 for the nine western chiefs, including Crowfoot, and he and interpreter Jean L’ Heureux accompanied them.
