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.

To what extent the Darien Highlanders espoused the cause of Great Britain would be difficult to fathom, but in all probability to no appreciable extent. The records exhibit that there were some royalists there, although when under British sway may have been such as a matter of protection, which was not uncommon throughout the Southern States. The record is exceedingly brief. On May 20, 1780, Charles McDonald, justice of peace for St. Andrew's parish (embracing Darien), signed the address to the King. Sir James Wright, royal governor of Georgia, writing to lord George Germain, dated February 16, 1782, says:

"Yesterday my Lord I Received Intelligence that two Partys of about 140 in the whole were gone over the Ogechee Ferry towards the Alatamaha River & had been in St. Andrews Parish (a Scotch settlement) & there Murdered 12 or 13 Loyal Subjects."[93]

The Highlanders were among the first to take action, and had no fears of the calamities of war. The military spirit of their ancestors showed no deterioration in their constitutions. During the second week in January, 1775, a district congress was held by the inhabitants of St. Andrew's Parish (now Darien), at which a series of resolutions were passed, embodying, with great force and earnestness, the views of the freeholders of that large and flourishing district. These resolutions, six in number, expressed first, their approbation of "the unparalleled moderation, the decent, but firm and manly, conduct of the loyal and brave people of Boston and Massachusetts Bay, to preserve their liberty;" their approval of "all the resolutions of the Grand American Congress," and their hearty and "cheerful accession to the association entered into by them, as the wisest and most moderate measure that could be adopted." The second resolution condemned the closing of the land offices, to the great detriment of Colonial growth, and to the injury of the industrious poor, declaring "that all encouragement should be given to the poor of every nation by every generous American." The third, animadverted upon the ministerial mandates which prevented colonial assemblies from passing such laws as the general exigencies of the provinces required, an especial grievance, as they affirmed, "in this young colony, where our internal police is not yet well settled." The fourth condemned the practice of making colonial officers dependent for salaries on Great Britain, "thus making them independent of the people, who should support them according to their usefulness and behavior." The fifth resolution declares "our disapprobation and abhorrence of the unnatural practice of slavery in America," and their purpose to urge "the manumission of our slaves in this colony, upon the most safe and equitable footing for the masters and themselves." And, lastly, they thereby chose delegates to represent the parish in a provincial congress, and instruct them to urge the appointment of two delegates to the Continental Congress, to be held in Philadelphia, in May.

Appended to these resolutions were the following articles of agreement or association:

"Being persuaded that the salvation of the rights and liberties of America depend, under God, on the firm union of the inhabitants in its vigorous prosecution of the measures necessary for its safety, and convinced of the necessity of preventing the anarchy and confusion which attend the dissolution of the powers of government, we, the freemen, freeholders, and inhabitants of the province of Georgia, being greatly alarmed at the avowed design of the Ministry to raise a revenue in America, and shocked by the bloody scene now acting in the Massachusetts Bay, do, in the most solemn manner, resolve never to become slaves; and do associate, under all the ties of religion, honor and love of country, to adopt and endeavor to carry into execution, whatever may be recommended by the Continental Congress, or resolved upon by our Provincial Convention that shall be appointed, for the purpose of preserving our Constitution, and opposing the execution of the several arbitrary and oppressive acts of the British Parliament, until a reconciliation between Great Britain and America, on constitutional principles, which we most ardently desire, can be obtained; and that we will in all things follow the advice of our general committee, to be appointed, respecting the purposes, aforesaid, the preservation of peace and good order, and the safety of individuals and private property."
