 In 1782, during the American Revolutionary War, a French squadron under Jean-François de Galaup, comte de Lapérouse captured and demolished York Factory and Prince of Wales Fort in support of the American rebels.In its trade with native peoples, Hudson's Bay Company exchanged wool blankets, called Hudson's Bay point blankets, for the beaver pelts trapped by aboriginal hunters.By 1700, point blankets accounted for more than 60 per cent of the trade.
