The Iroquais continued to control the New France landscape and rushed to the shores of the fortified colonies of Quebec and Montreal. In May 1660, an Iroquise force of 160 warriors attacked Montreal and took 17 French settlers. The following year, 250 warriors attacked and took ten prisoners.  In 1661 and 1662, the Iroquois made several incursions against the Abenakis allied to the French. The French Crown has ordered an amendment to the Government of Canada. They set up a small military force made up of French, Huron and Algonquins to counter the Iroqua attacks, but the Iroquais attacked them by venturing into the countryside. Only 29 of the French survived and escaped; Five were captured and tortured to death by the Iroquais. Despite their victory, the Iroquais also suffered a considerable number of casualties and their leaders began to consider negotiating peace with the French.  In 1610/1614, the Dutch established a series of seasonal trading posts on the Hudson and Delaware rivers, including one on Castle Island, on the eastern outskirts of Mohawk territory near Albany.  This gave the Iroquois direct access to European markets through the Mohawks. Trade efforts from the Netherlands and possible colonies in New Jersey and Delaware quickly established trade with the Delaware Coastal Base (Lenape) and the Southern Susquehannock Tribe. The Dutch founded Fort Nassau in 1614 and 1624 the Fort Orange (both Albany) which the Iroquois had to leave for the French and their allied tribes, or cross the southern tribal regions to join the European merchants.
The Dutch supplied guns to the Mohawks and other Iroquois.  In addition, the new mail offered valuable tools that the Iroquois could obtain in exchange for animal skins.  They began hunting fur on a large scale to meet their peoples` demand for new products.  In 1628, the Mohawks defeated the Mahicans, pushed them east of the Hudson River and established a commercial monopoly with the Dutch at Fort Orange, New Netherland. The Susquehannocks were also well armed by Dutch merchants, and they effectively reduced the Delaware force and managed to win a long-running war with Maryland settlers.  In the 1630s, the Iroquois were entirely armed with European weapons by their trade with the Dutch.
