The Secretary of War later sought to appease the irascible major general by offering a wholly plausible explanation of the sudden reversal of the Government's policy; and the expenses of the troops on the return march were fully met out of the national treasury. But Jackson drew from the experience only gall and wormwood. About the time when the men reached Natchez, Congress definitely authorized the President to take possession of Mobile and that part of Florida west of the Perdido River; and, back once more in the humdrum life of Nashville, the disappointed officer could only sit idly by while his pet project was successfully carried out by General Wilkinson, the man whom, perhaps above all others, he loathed. But other work was preparing; and, after all, most of Florida was yet to be won. In the late summer of 1813 the western country was startled by news of a sudden attack of a band of upwards of a thousand Creeks on Fort Mims, Alabama, culminating in a massacre in which two hundred and fifty white men, women, and children lost their lives. It was the most bloody occurrence of the kind in several decades, and it brought instantly to a head a situation which Jackson, in common with many other military men, had long viewed with apprehension. From time immemorial the broad stretches of hill and valley land southwards from the winding Tennessee to the Gulf were occupied, or used as hunting grounds, by the warlike tribes forming the loose-knit Creek Confederacy. Much of this land was extremely fertile, and most of it required little labor to prepare it for cultivation. Consequently after 1800 the influx of white settlers, mainly cotton raisers, was heavy; and by 1812 the great triangular area between the Alabama and the Tombigbee, as well as extensive tracts along the upper Tombigbee and the Mobile, was quite fully occupied. The heart of the Creek country was the region about the Coosa and Tallapoosa rivers, which join in central Alabama to form the stream which bears the State's name. But not even this district was immune from encroachment. The Creeks were not of a sort to submit to the loss of their lands without a struggle. Though Tecumseh, in 1811, had brought them to the point of an uprising, his plans were not carried out, and it remained for the news of hostilities between the United States and Great Britain to rouse the war spirit afresh. In a short time the entire Creek country was aflame. Arms and ammunition the Indians obtained from the Spaniards across the Florida border, and Colonel Edward Nicholls, now stationed at Pensacola as provisional British Governor, gave them open encouragement. The danger was understood not only among the people of the Southwest but in Washington. Before plans of defense could be carried into effect, however, the war broke out, and the wretched people who had crowded into the flimsy stockade called by courtesy Fort Mims were massacred.
