In spite of these agreements, continued encroachment by settlers onto Indian lands prompted reprisals, which primarily came from hostile Chickamauga Cherokee and Creek Indians. The Spanish, who controlled Florida along the Gulf of Mexico coast and still disputed the southern borders of the United States, fifteen years after the end of the Revolutionary War, encouraged and armed the southern tribes. These attacks persisted throughout 1792 and 1793, with the Mero settlements bearing the brunt of the hostilities. Ziegler's Station near modern Hendersonville was destroyed, and Mero defenders had to rally to thwart a large invasion at Buchanan's Station near Nashville. In spite of growing impatience from frontiersmen, Secretary of War Knox refused to authorize an invasion of Indian territory.
