Following the events in Kentucky, Burr returned to the West later in 1806 to recruit more volunteers for a military expedition down the Mississippi River. He began using Blennerhassett Island in the Ohio River to store men and supplies. The Governor of Ohio grew suspicious of the activity there, and ordered the state militia to raid the island and seize all supplies. Blennerhassett escaped with one boat, and he met Burr at the operation's headquarters on the Cumberland River. With a significantly smaller force, the two headed down the Ohio to the Mississippi River and New Orleans. Wilkinson had vowed to supply troops at New Orleans, but he concluded that the conspiracy was bound to fail, and rather than providing troops, Wilkinson revealed Burr's plan to President Jefferson.
