and forced to withdraw to his base at Fort Strother. In January, Floyd's force of 1,300 state militia and 400 Creek moved to join the United States forces in Tennessee, but they were attacked in camp on the Calibee Creek by Tukabatchee Muscogees on 27 January. Jackson's force increased in numbers with the arrival of United States Army soldiers and a second draft of Tennessee state militia, Cherokee, and pro-American Creek swelled his army to around 5,000. In March 1814, they moved south to attack the Red Sticks. On 27 March, Jackson decisively defeated a force of about a thousand Red Sticks at Horseshoe Bend, killing 800 of them at a cost of 49 killed and 154 wounded. Jackson then moved his army to Fort Jackson on the Alabama River. He promptly turned on the pro-American Creek who had fought with him and compelled their chieftains, along with a single Red Stick chieftain, to sign the Treaty of Fort Jackson, which forced the Creek tribe as a whole to cede most of western Georgia and part of Alabama to the U.S. Both Hawkins and the pro-American Creek strongly opposed the treaty, which they regarded as deeply unjust. The treaty also demanded that the Creek cease communicating with the British and Spanish and trade only with United States-approved agents. British aid to the Red Sticks arrived after the end of the Napoleonic Wars in April 1814 and after Admiral Alexander Cochrane assumed command from Admiral Warren in March. Captain Hugh Pigot arrived with two ships to arm the Red Sticks. He thought that some 6,600 warriors could be armed and recruited. It was overly optimistic at best. The Red Sticks were in the process of being destroyed as a military force. In April 1814, the British established an outpost on the Apalachicola River (Prospect Bluff Historic Sites). Cochrane sent a company of Royal Marines commanded by Edward Nicolls, the vessels and and further supplies to meet the Indians in the region. In addition to training them, Nicolls was tasked to raise a force from escaped slaves as part of the Corps of Colonial Marines. In July 1814, General Jackson complained to the governor of Pensacola, Mateo González Manrique that combatants from the Creek War were being harboured in Spanish territory and made reference to the British presence on Spanish soil. Although he gave an angry reply to Jackson, Manrique was alarmed
