Shelby resorted to conscription. By the time the soldiers arrived, winter had set in. He ordered the men to go home and return in the spring. After a winter filled with Indian attacks, including one which claimed the life of Shelby's younger brother Evan Shelby III, Kentucky militia units won some minor victories over the Indians in early 1794. In spring the response to Wayne's call for troops was more enthusiastic; 1,600 volunteers mustered at Fort Greenville and were hastily trained. By August, 1794, Wayne was on the offensive against the Indians and dealt them a decisive blow at the August 20, 1794 Battle of Fallen Timbers. This victory, and the ensuing Treaty of Greenville, secured the territory, and although Shelby did not agree with some of the restrictions placed upon western settlers by this treaty, he abided by its terms and enforced those that were under his jurisdiction. Another major concern of the Shelby administration was free navigation on the Mississippi River, which was vital to the state's economic interests. For political reasons the Spanish had closed the port at New Orleans to the Americans. This would have been the natural market for the tobacco, flour and hemp grown by Kentucky farmers; overland routes were too expensive to be profitable. This made it difficult for land speculators to entice immigration to the area to turn a profit on their investments. Many Kentuckians felt the federal government was not acting decisively or quickly enough to remedy this situation. Citizen Genêt affair While Kentuckians despised the British and Spanish, they had a strong affinity for the French. They admired the republican government that had arisen from the French Revolution, and they had not forgotten France's aid during the Revolutionary War. When French Ambassador Edmond-Charles Genêt, popularly known as Citizen Genêt, arrived in the United States in April 1793, George Rogers Clark was already considering an expedition to capture Spanish lands in the west. Genêt's agent, André Michaux, was dispatched to Kentucky to assess the support of Kentuckians toward Clark's expedition. When he gained an audience with Governor Shelby, he did so with letters of introduction from Secretary of State Thomas Jefferson and Kentucky Senator John Brown. Jefferson had written a separate letter to Shelby warning him against aiding the French schemes and informing him that negotiations were under way with the Spanish regarding trade on the Mississippi. When the letter was
