In the following year, Harrison blamed the Shawnee for the murder of a handful of men on the frontier and for the theft of a boatload of salt, but more importantly sent a stream of letters to Washington requesting permission to move against them. He wrote, "In Indian warfare there is no security but in offensive measures." He summoned Tecumseh to a meeting in the summer of 1811. As before, Tecumseh presented himself as an eloquent speaker but the meeting proved unproductive. Tecumseh informed Harrison he was leaving to recruit among the Muscogee and Choctaws and asked to wait upon his return to commence settlement on the disputed lands. He said he wanted "no mischief" during his absence, a plea he made to Harrison and Tenskwatawa.
