FREEMAN'S EXPEDITION was arranged to carry out President Thomas Jefferson's orders in 1805 to explore the Red River of Louisiana and Texas. With a party of twenty-five men and three boats, Thomas Freeman left Fort Adams, Mississippi, at the mouth of Red River, in April 1806. Forty-five miles above Natchitoches, Louisiana, the party left the last white settlement behind. At a point 635 miles from the mouth of the Red River, the group was turned back by a Spanish military party, having added little to American knowledge of the new Louisiana Purchase except for an accurate map of the lower Red River.
