The year 1743 opened with fresh alarms of a new invasion, jointly of the French and Spanish. The Governor of Cuba offered to invade Georgia and Carolina, with ten thousand men, most of whom were then in Havanna. Oglethorpe, with his greatly reduced force, was left alone to bear the burden of defending Georgia. Believing that a sudden blow would enhance his prospects, he took his measures, and accordingly, on Saturday, February 26, 1743, the detachment destined for Florida, consisting of a portion of the Highlanders, rangers and regulars, appeared under arms at Frederica, and on March 9th, landed in Florida. He advanced upon St. Augustine, and used every device to decoy them into an ambush; but even failed to provoke the garrison. Having no cannon with him, he returned to Frederica, without the loss of a man. This expedition was attended with great toil, fatigue and privation, but borne cheerfully. A few slight eruptive efforts were made, but each party kept its own borders, and the slight conflicts in America were lost in the universal conflagration in Europe. The Highlanders had borne more than their share of the burdens of war, and had lost heavily. Their families had shared in their privations. The majority had remained loyal to Oglethorpe, and proved that in every emergency they could be depended on. In later years the losses were partially supplied by accessions from their countrymen. With all the advantages that Georgia offered and the inducements held out to emigrants, the growth was very slow. In 1761 the whole number of white inhabitants amounted to but sixty-one hundred. However, in 1773, or twelve years later, it had leaped to eighteen thousand white and fifteen thousand black. The reasons assigned for this increase were the great inducements held out to people to come and settle where they could get new and good lands at a moderate cost, with plenty of good range for cattle, horses and hogs, and where they would not be so pent up and confined as in the more thickly settled provinces. The Macintoshes had ever been foremost, and in the attempt to consolidate Georgia with Carolina they were prominent in their opposition to the scheme. Forty years in America had endeared the Highlanders of Darien to the fortunes of their adopted country. The children knew of none other, save as they heard it from the lips of their parents. Free in their inclinations, and with their environments it is not surprising that they should become imbued with the principles of the American Revolution. Their foremost leader, who gained imperishable renown, was Lachlan Macintosh, son of John Mor. His brother, William, also took a very active part, and made great sacrifices. At one time he was pursued beyond the Alatamaha and his negroes taken from him.
