Its Abortive Efforts in Kentucky. Before this occurred the South Carolina Yazoo Company had striven to take possession of its purchase by organizing a military expedition to go down the Mississippi from Kentucky. For commander of this expedition choice was made of a Revolutionary soldier named James O'Fallon, who went to Kentucky, where he married Clark's sister. He entered into relations with Wilkinson, who drew him into the tangled web of Spanish intrigue. He raised soldiers, and drew up a formal contract, entered into between the South Carolina Yazoo Company and their troops of the Yazoo Battalion--over five hundred men in all, cavalry, artillery and infantry. Each private was to receive two hundred and fifty acres of "stipendiary" lands and the officers in proportion, up to the Lieutenant Colonel, who was to receive six thousand. Commissions were formally issued, and the positions of all the regular officers were filled, so that the invasion was on the point of taking place. [Footnote: American State Papers, Indian Affairs, I., James O'Fallon to the President of the United States, Lexington, Sept. 25, 1790, etc., etc.] However, the Spanish authorities called the matter to the attention of the United States, and the Federal Government put a prompt stop to the movement. [Footnote: Draper MSS., Spanish Documents, Carondelet to Alcudia, Jan. 1, 1794, and May 31, 1794.] O'Fallon was himself threatened with arrest by the Federal officers, and had to abandon his project. [Footnote: Draper MSS., Clark and O'Fallon Papers, anonymous letter to James O'Fallon, Lexington, March 30, 1791, etc., etc.] He afterwards re-established his relations with the Government, and became one of Wayne's correspondents; [Footnote: Draper MSS., Wayne to O'Fallon, Sept. 16, 1793.] but he entered heartily into Clark's plans for the expedition under Genet, and, like all the other participators in that wretched affair, became involved in broils with Clark and every one else.
