n the early 1800s more traders arrived from the east to sell their goods in Santa Fe, among them Jean Baptiste La Lande from Illinois and a Kentuckian, James Purcell. La Lande successfully sold his goods and settled in Santa Fe, but Purcell was arrested and incarcerated until 1824. In 1806 the United States government sent Zebulon Pike on an exploring and military spying expedition to Colorado. He and his men traveled part of the Santa Fe Trail, first following the Republican River in Kansas, then the Arkansas into Colorado where they were taken into custody by Spanish troops and marched to Santa Fe. In 1810 he published an account of his journey, giving the first published report of a possible route to Santa Fe. In 1807 a French trader from St. Louis, Jacques Clamorgan, successfully sold his goods in Santa Fe and Chihuahua. Later American traders were not so lucky; in 1812 at least 12 of them, led by Robert McKnight and James Baird, reached Taos, were arrested and taken to Santa Fe where their goods were confiscated and sold at auction. They were later taken to Chihuahua, jailed for conspiracy and not released until 1821. Two other French traders from St. Louis, Auguste Chouteau and Jules de Mun, had their goods confiscated and sold in 1817.
