Henry settled on a farm in northern
Vermont, and also studied law. Here he remained five years studying law and, occasionally, writing articles for the press against the republican form of government. These attracted the attention of Sir
James Craig, then Governor-General of Canada, who employed him in 1809 to find out the extent of the reported disaffection to the U.S. government in
New England. Henry spent three months in Boston in this employment, living at the
Exchange Coffee House. He reported constantly to Craig by letter, and at one time thought that in the event of war between Great Britain and the United States, Massachusetts would take the lead in establishing a northern confederacy, which might, in the end, ally itself with Great Britain. Craig promised Henry office in Canada, but died soon afterward, and the spy's efforts to obtain his reward in London, meeting with no success, he returned to the United States. En route to the United States in September 1811, he made the acquaintance of one Comte Edouard de Crillon who Henry took into his confidence and to whom he explained the entire affair. De Crillon suggested that Henry sell the correspondence to President Madison as Madison was seeking grounds on which to declare war on Britain. In reality, De Crillon was not a French count, but a notorious
con artist whose real name was . Henry, on February 10, 1812, sold the documents, called the
Henry Papers, to President
James Madison, who paid him $50,000 for his information, the other $40,000 of his reward to be guaranteed by the deed to an ancestral estate of de Crillon's. (Some sources state that Henry gave the bulk of the cash to de Crillon in exchange for the deed to de Crillon's estate in France named St. Martial.) Henry sailed from New York for France aboard the sloop
USS Wasp on March 9, 1812. The estate in
Gascony granted by the "Count de Crillon" did not exist, as Crillon proved to be an impostor - possibly in the employ of Emperor
Napoleon to help distract the United Kingdom in a war with the United States prior to his invasion of Russia. His disclosures, although considered by some to be fraudulent, were believed by President Madison and his Republican Party. They were made the subject of a special message to Congress, and created much excitement throughout the country. Some Federalists alleged that it was all a political trick that had been devised by the President to cause war with Great Britain. Historians have been sharply critical of Madison. Richard Leopold wrote, "In buying sight unseen, in February, 1812, the worthless Henry letters at the cost of a badly needed frigate in order to expose the supposed intrigues of the New England Federalists, Madison and Secretary of State Monroe looked like fools as well as knaves." ==Later life==
