In June of 1824 James Ohio Pattie, then in his early 20's, left Kentucky with his father, Sylvester, and headed west. They reached Taos, New Mexico, traveled down the Rio Grande, fought with Indians, rescued two white women who had been captured by Comanches, crossed over the Mogollon Mountains (they had to eat one of their horses; later they had to eat their dogs also), and for a while ran a mine and fought more Indians for the Mexicans near Silver City. In southern New Mexico, a party of French trappers, against Pattie's advice, consorted with the wrong Indians and they were massacred, their body parts strewn around the Indian village. The Patties and thirty others joined together "under a genuine American leader, who could be entirely relied on" to take revenge on the village.After the battle and some similar adventures, the Patties resumed trapping and followed the Gila west to Yuma, trapping beaver and fighting with more Indians, and then crossed the California desert, reaching San Diego in March of 1828. In San Diego, the Patties and their American companions were promptly arrested by Governor Echeandia, who confiscated their fortune in furs and threw the men in jail. There they languished, and the elder Pattie died. Ever resourceful, young James struck up a romance with a woman of high station. He recuperated under her care, and began working part-time from jail as a translator for the governor. Finally, news reached the governor of a smallpox epidemic in the north. Rather fortuitously (ahem), Pattie had a quantity of smallpox vaccine with him. He made a deal with the governor: his own and his companions' freedom in exchange for vaccinating the populace. During his six month trip up the coast from San Diego to Fort Ross, just north of today's San Francisco, Pattie claims to have vaccinated nearly 22,000 Mexicans, missionaries, Indians, and settlers.Pattie found it hard to stay out of trouble, however. In Monterey he joined a revolt against the governor, but then switched sides again. The governor (either grateful or just hoping to get rid of him) finally gave Pattie a passport to Mexico City, where Pattie met with officials and tried to obtain restitution for his jail time and lost furs. In 1830 Pattie sailed for New Orleans, arriving home again in August, six years after he and his father had headed West. He dictated his story to newspaperman Timothy Flint, and the book came out a year later. History loses track of Pattie after that. He probably died in a cholera epidemic that began near Augusta, Kentucky, in June 1833. But we will always have The Personal Narrative of James O. Pattie.
