Officers at the besieged Fort Pitt had already attempted to do what Amherst and Bouquet were discussing. During a parley at Fort Pitt on June 24, 1763, Ecuyer gave Delaware representatives, Turtleheart and Mamaltee, two blankets and a handkerchief that had been exposed to smallpox, hoping to spread the disease to the Native Americans in order to "extirpate" them from the territory. William Trent, the militia commander, left records that showed the purpose of giving the blankets was "to Convey the Smallpox to the Indians." Turtleheart and Killbuck would later represent the Delaware at the Treaty of Fort Stanwix in 1768.
