The United States enforced its claim by military occupation of the disputed district before the close of the War of 1812.

During the course of the war, the British forces had occupied Pensacola. The Spanish governor either could not, or would not, prevent them from doing so. Florida became thus, in spite of its nominal neutral status, a base of operations for the enemy of the United States. No more convincing evidence of the necessity for its annexation to the United States could have been offered. It was thus seen that not only the geography and the national growth of the Union demanded it, but that the safety of the Union, in case of war with any power, required it. The sea is the natural boundary of the United States on the south, and it was the "manifest destiny" of the Union to reach it.
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 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.

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.
