The missionary W. H. Collison describes having seen a Haida fleet of around forty canoes. However, he does not provide the number of warriors in these canoes, and there are no other known accounts that describe the number of warriors in a war party. The structure of a Haida war party generally followed that of the community itself, the only difference being that the chief took the lead during battles; otherwise his title was more or less meaningless. Medicine men were often brought along raids or before battles to “destroy the souls of enemies” and ensure victory.
