The Fort in the Wilderness by Edward Stratemeyer

After many months of preparation, and after numerous councils of war, the great conspiracy instituted by Pontiac was now complete, and the Indians were ready to strike the English such a blow as had seldom, if ever, been struck before.

The principal meeting of the Indians was held on the river Ecores, only a few miles from where the city of Detroit now stands, but other meetings were held in the villages of the Pottawattamies, the Sacs, the Ojibwas, the Wyandottes, the Miamis, and many other tribes. Wampum belts were passed, and the arguments in favor of driving the English out waxed hot and bloodthirsty. It was reasoned (and truthfully, as later events have proved), that if the hated whites were allowed to remain, sooner or later they would overrun the whole of the red men's hunting grounds, and the Indians would not know where to go to gain their living.
