The occupation of Florida would have been a sound and justifiable policy for the United States, had the Government commanded a sufficient military force for the purpose, when the British troops took possession of Pensacola. General Jackson did expel the British from Pensacola, but restored the place to the Spanish authorities, in order to avoid a conflict with Spain while engaged in war with Great Britain. We know now that the Congress of the United States had, by secret acts passed before the beginning of the War, authorized the {25} President to occupy Florida _east_ of the Perdido temporarily. The President did not deem it wise, under the circumstances which prevailed, to make use of this power; but the readiness of the Congress to intrust the President with the authority to take possession of the territory of a friendly power certainly shows that a strong feeling existed among the representatives of the people that Florida must be acquired by the United States upon the first fair opportunity. [Sidenote: The hold of the Spaniards on Florida weakened by the War of 1812.] The occasion was destined soon to appear. The power of Spain upon the American continents was everywhere in rapid decline. At the close of the War of 1812, the Spanish occupation in Florida was confined substantially to three points--Pensacola, St. Mark's, and St. Augustine. The remainder of the province, by far the greater part of it, was a free zone, in which desperate adventurers of every race and land might congregate, from which they might make their raids for murder and pillage into the United States, and into which they might escape again with their prisoners and plunder. [Sidenote: The British troops in Florida during and after the War of 1812.] We have noticed the occupation of Pensacola by the British troops during the War of 1812, and their expulsion by General Jackson from this position in November of 1814. After this, they concentrated upon the Appalachicola and established a fort some fifteen miles above the mouth of this stream for their head-quarters and base of operations. The British commander, one Colonel Nicholls, pursued from this point the policy which he had already inaugurated at Pensacola. This policy was the collection and organization of fugitive negroes, Indians, and adventurers of every character, and their employment in raids into the territory, and attacks upon the inhabitants, of the United States. {26} It appears that Colonel Nicholls did not regard the Treaty between the United States and Great Britain concluding the War as putting an end necessarily to his hostile movements. He remained in command at his fort on the Appalachicola for several months after the ratification of the Treaty, and then went to London, taking with him the Indian priest Francis, for the purpose of securing a treaty of alliance between the British Government and his band of outlaws in Florida.
