Congress passed a joint resolution, approved January 15, 1811, to provide for the temporary occupation of the disputed territory and declaring that the territory should remain subject to future negotiation. On March 11, 1811, rebellious elements again raised the Lone Star flag of the West Florida Republic, forcing Governor Claiborne to dispatch troops to enforce his authority. Spain did not agree to relinquish its title to any of the West Florida territory occupied by the United States until 1819, upon the signing of the Adams–Onís Treaty.
