There was a letter bearing Cameron's name stating that fifteen hundred savages from the Cherokee and Creek nations were to join with British troops landed at Pensacola in an expedition against the southern frontier colonies.
This letter was brought to Watauga at dead of night by a masked man who slipped it through a window and rode away.

Apparently John Sevier did not believe the military information contained in the mysterious missive, for he communicated nothing of it to the Virginia Committee.
In recent years the facts have come to light.

This mysterious letter and others of a similar tenor bearing forged signatures are cited in a report by the British Agent, John Stuart, to his Government.

It appears that such inflammatory missives had been industriously scattered through the back settlements of both Carolinas.

There are also letters from Stuart to Lord Dartmouth, dated a year earlier, urging that something be done immediately to counteract rumors set afloat that the British were endeavoring to instigate both the Indians and the negroes to attack the Americans.
Now it is, of course, an established fact that both the British and the American armies used Indians in the War of Independence, even as both together had used them against the French and the Spanish and their allied Indians.
