It is estimated that more than 3,500 Aboriginal soldiers left their families and communities to fight in the First World War. Many of these soldiers, who risked their lives or were killed in action, were later recognized for their bravery and heroism. Many received medals and other honours. The file pertaining to the men from the File Hills Agency, Balcarres, Saskatchewan, and the material pertaining to the formation of the League of Indians of Canada by Lieutenant Frederick O. Loft, both from the Red Series, have been digitized in colour from the original documents.
