In the spring of 1818, General Jackson made his celebrated incursion into Florida, and by a series of energetic movements followed the Seminoles and Creeks to their fastnesses, and forever crushed the power of those formidable tribes for offensive operations.

In the latter part of 1817, a revolutionary party took possession of Amelia Island, and raised a soi disant patriot flag at Fernandina, supported mainly in the enterprise by adventurers from the United States; M'Gregor was assisted by officers of the United States army. An expedition was sent from St. Augustine by the Spanish governor to eject the invaders, which failed. One Aury, an English adventurer, for a time held command there; and also a Mr. Hubbard, formerly sheriff of New York, who was the civil governor, and died there. The United States troops eventually interfered; but negotiations for the cession put a stop to further hostilities.

The king of Spain, finding his possessions in Florida utterly worthless to his crown, and only an expense to sustain the garrisons, while the repeated attempts to disturb its political relations prevented any beneficial progress towards its settlement, gladly agreed, in 1819, to a transfer of Florida to the United States for five millions of dollars.

An English gentleman who visited St. Augustine in 1817, gives his impressions of the place as follows: "Emerging from the solitudes and shades of the pine forests, we espied the distant yet distinct lights of the watch towers of the fortress of St. Augustine, delightful beacons to my weary pilgrimage. The clock was striking ten as I reached the foot of the drawbridge; the sentinels were passing the alerto, as I demanded entrance; having answered the preliminary questions, the draw-bridge was slowly lowered. The officer of the guard, having received my name and wishes, sent a communication to the governor, who issued orders for my immediate admission. On opening the gate, the guard was ready to receive me; and a file of men, with their officer, escorted me to his Excellency, who expressed his satisfaction at my revisit to Florida. I soon retired to the luxury of repose, and the following morning was greeted as an old acquaintance by the members of this little community.

"I had arrived at a season of general relaxation, on the eve of the carnival, which is celebrated with much gayety in all Catholic countries. Masks, dominoes, harlequins, punchinellos, and a great variety of grotesque disguises, on horseback, in cars, gigs, and on foot, paraded the streets with guitars, violins, and other instruments; and in the evenings, the houses were open to receive masks, and balls were given in every direction. I was told that in their better days, when their pay was regularly remitted from the Havana, these amusements were admirably conducted, and the rich dresses exhibited on these occasions, were not eclipsed by their more fashionable friends in Cuba; but poverty had lessoned their spirit for enjoyment, as well as the means for procuring it; enough, however, remained to amuse an idle spectator, and I entered with alacrity into their diversions.

"About thirty of the hunting warriors of the Seminoles, with their squaws, had arrived, for the purpose of selling the produce of the chase, consisting of bear, deer, tiger, and other skins, bears' grease, and other trifling articles. This savage race, once the lords of the ascendant, are the most formidable border enemies of the United States. This party had arrived, after a range of six months, for the purpose of sale and barter. After trafficking for their commodities, they were seen at various parts of the town, assembled in small groups, seated upon their haunches, like monkeys, passing round their bottles of aque dente (the rum of Cuba), their repeated draughts upon which soon exhausted their contents; they then slept off the effects of intoxication, under the walls, exposed to the influence of the sun. Their appearance was extremely wretched; their skins of a dark, dirty, chocolate color, with long, straight, black hair, over which they had spread a quantity of bears' grease. In their ears, and the cartilages of the nose, were inserted rings of silver and brass, with pendants of various shapes; their features prominent and harsh, and their eyes had a wild and ferocious expression.

"A torn blanket, or an ill-fashioned dirty linen jacket, is the general costume of these Indians; a triangular piece of cloth passes around the loins; the women vary in their apparel by merely wearing short petticoats, the original colors of which were not distinguishable from the various incrustations of dirt. Some of the young squaws were tolerably agreeable, and if well washed and dressed would not have been uninteresting; but the elder squaws wore the air of misery and debasement.

"The garrison is composed of a detachment from the Royal regiment of Cuba, with some black troops; who together form a respectable force. The fort and bastions are built of the same material as the houses of the town, coquina. This marine substance is superior to stone, not being liable to splinter from the effects of bombardment; it receives and imbeds the shot, which adds rather than detracts from its strength and security.

"The houses and the rear of the town are intersected and covered with orange groves; their golden fruit and deep green foliage, not only render the air agreeable, but beautify the appearance of this interesting little town, in the centre of which (the square) rises a large structure dedicated to the Catholic religion. At the upper end are the remains of a very considerable house, the former residence of the governor of this settlement; but now (1817), in a state of dilapidation and decay, from age and inattention.

"At the southern extremity of the town, stands a large building, formerly a monastery of Carthusian Friars, but now occupied as a barrack for the troops of the garrison. At a little distance are four stacks of chimnies, the sole remains of a beautiful range of barracks, built during the occupancy of the British, from 1763 to 1783; for three years the 29th regiment was stationed there, and in that time they did not lose a single man. The proverbial salubrity of the climate, has obtained for St. Augustine the designation of the Montpelier of Forth America; indeed, such is the general character of the Province of East Florida.
