Exploring the Red | Arkansas Democrat Gazette

Exploring the Red | Arkansas Democrat Gazette recounts how the Red River shaped southwest Arkansas and the early U.S. push to map new territory after the 1803 Louisiana Purchase. The Great Excursion, led by Thomas Freeman and Peter Custis, was ordered by President Thomas Jefferson to ascend the Red River in search of its headwaters while documenting coordinates, climate, and ecology. Freeman, a 1784 Irish immigrant surveyor from Philadelphia, served as civilian leader, while Custis, a trained naturalist and University of Pennsylvania medical student, took on natural history work. Congress funded the 24-man party with $5,000, making it among the best equipped expeditions of the early 1800s. Departing Fort Adams on April 19, 1806, they reached Natchitoches on May 19, then battled the Great Raft for 14 days. By late July they met Caddo and Creek communities near the current Arkansas border and faced warnings about Spanish forces.
