Within a year the Comanches regretted this agreement, and had destroyed their copy. When the United States annexed Texas in 1846, it inherited its problem with Comanche raiding and a boundary line between the settlements and Comancheria. An immediate step by the United States was to announce its authority and sign a treaty with the Comanches and other Texas tribes to replace the Texas treaty of the previous year. This was done in May 1846 on the upper Brazos River (Butler-Lewis Treaty). Signed by the Penateka/Hois Comanches (also Ioni, Anadarko, Caddo, Lipan Apache, Wichita, and Waco), the treaty promised, besides peace and friendship, trading posts, a visit by a Comanche delegation to Washington, D.C., and a one-time payment of $18,000 in goods. A boundary line was alluded to, but not defined.
