A few weeks later a number of Mohawks led by Joseph Brant (Thayendanegea) put another band of Delawares to rout, killing their chief and taking three prisoners.
These attacks of the Iroquois disheartened the Shawnees and Delawares and greatly alarmed the Senecas, who, trembling lest their own country should be laid waste, sent a deputation of four hundred of their chief men to Johnson Hall--Sir William Johnson's residence on the Mohawk--to sue for peace.

It was agreed that the Senecas should at once stop all hostilities, never again take up arms against the British, deliver up all prisoners at Johnson Hall, cede to His Majesty the Niagara carrying-place, allow the free passage of troops through their country, renounce all intercourse with the Delawares and Shawnees, and assist the British in punishing them.

Thus, early in 1764, through the energy and diplomacy of Sir William Johnson, the powerful Senecas were brought to terms.
With the opening of spring preparations began in earnest for a twofold invasion of the Indian country.

One army was to proceed to Detroit by way of Niagara and the Lakes, and another from Fort Pitt was to take the field against the Delawares and the Shawnees.

To Colonel John Bradstreet, who in 1758 had won distinction by his capture of Fort Frontenac, was assigned the command of the contingent that was to go to Detroit.
