By the summer of 1806 Burr knew that he could not get money from England to further his plans. He would have to depend on his own countrymen in any attack on Mexico or Spain. His journey had showed him that many of them were eager to follow his lead. Troubles were daily increasing along the borders of Florida and Mexico. It looked easy to take an army into Florida, but there would be more profit in the rich country to the southwest. His friend, General Wilkinson, had just been sent to drive the Mexicans across the Sabine River, the western boundary of Louisiana, and Burr thought this was a good chance to go west again, and perhaps call the settlers to arms. Men he trusted started west early in the summer of 1806, and Burr, with his daughter, and a Colonel De Pestre, who had fought in the French Revolution, and a few friends and servants, set out in August for their meeting-place on Blennerhassett Island. When he arrived there he was warmly welcomed by the owner. Burr showed Blennerhassett how he could make his fortune in Mexico, because if the conspiracy were successful they could take a large part of that country for themselves. Fired by Burr's story the men on the island immediately began preparations. They sent to the town of Marietta for one hundred barrels of pork, and contracted to have fifteen boats delivered at the island the following December. A kiln was built near Blennerhassett's house for drying corn, which was then ground into meal, and packed for shipping. All sorts of provisions were purchased, and the Blennerhassett family prepared to send their household goods down the river. Word of the plans spread, and men in various towns near the Ohio made ready to join the expedition. When the leader should send out his messengers recruits would come pouring in. In the meantime Burr himself had left the little island and covered a wide stretch of country. He wanted to be sure of Andrew Jackson's aid, and he found that fiery warrior as ready as ever to fight Spaniard or Mexican in the cause of liberty. The general still thought that his friend Burr's only object was to free all of North America. Eager in that cause, Jackson sent word to the Tennessee militia, urging them to be ready for instant duty against the Spaniards, who, he said, had already captured several citizens of the United States, had cut down our flag, had driven our explorers away from the Red River, and had taken an insulting position on the east bank of the River Sabine, in the territory of Orleans. He wrote to President Jefferson offering to lead his Tennessee militia against the troops of Spain. A large part of the country expected war at once. Burr, for his own purposes, did all he could to inflame this warlike feeling.
