Got the book "Thundersticks" from the library. It's a history of the arms trade with Native Americans from the initial contact through the nineteenth century.
I've only read the first couple chapters--it seems a bit too scholarly for my current ability to focus. But a couple things struck me:
- the pattern of arms dealing in the seventeenth century is similar to the pattern in modern times: countries/companies with advanced technology sell weapons to those who don't have the capability to produce their own. (Natives weren't able to produce their own weapons or gunpowder, while they could make their own bullets if they could obtain the lead.) And the sales are used to influence international/intertribal politics, just as the Soviet Union/Russia sold weapons to India and the US sells to Israel and Saudi Arabia.
- what was surprising was how the natives financed their purchases. Furs--beaver skins and deer skins, I knew. But capturing slaves from other tribes for resale to colonists, possibly for export to the Caribbean--that was new.
