These tribal warriors are willing to fight for foreign powers, but at a price.
The bow is a practical tool: it puts food in bellies as well as killing enemies. A skilled bowman can stalk his prey (man or beast) in utter silence, before killing with a well-aimed shot of a broad-headed arrow, designed to cause massive bleeding. In the time it takes to fire and reload a musket, a good bowman can fire half a dozen aimed shots, and probably have moved to better ground while doing so.
In the early days of their contact with the various foreign powers that colonized America, the tribes were glad to co-operate with them, and formed alliances with the French, British and Dutch. The tribes soon became involved in trade, and often ended up fighting proxy wars on behalf of their allies.
