Oglethorpe had previously taken the precaution, lest the Highlanders might be apprehensive of an attack by the Spaniards, Indians, or other enemies, while their houses were in process of construction, to send Captain James McPherson, who commanded the rangers upon the Savannah, overland to support them. This troop arrived while Oglethorpe was yet present. Soon after they were visited by the Indians, who were attracted by their costume, and ever after retained an admiration for them, which was enhanced by the Highlanders entering into their wild sports, and joining them in the chase. In order to connect the new settlement with direct land communication with the other colonists, Oglethorpe, in March, directed Hugh MacKay, with a detachment of twelve rangers, to conduct Walter Augustin, who ran a traverse line from Savannah by Fort Argyle to Darien, in order to locate a roadway. It was during Oglethorpe's first trip to the Highland settlement that he encamped on Cumberland island, and on the extreme western point, which commands the passage of boats from the southward, marked out a fort to be called St. Andrews, and gave Captain Hugh MacKay orders to build it. The work commenced immediately, thirty Highlanders being employed in the labor. On March 26th Oglethorpe, visiting the place, was astonished to find the fort in such an advanced stage of completion; the ditch was dug, the parapet was raised with wood and earth on the land side, and the small wood was cleared fifty yards round the fort. This seemed to be the more extraordinary because MacKay had no engineer, nor any other assistance in that way, except the directions originally given. Besides it was very difficult to raise the works, the ground being a loose sand. They were forced to lay the trees and sand alternately,--the trees preventing the sand from falling, and the sand the wood from fire. He returned thanks to the Highlanders and offered to take any of them back to their settlement, but all refused so long as there was any danger from the Spaniards, in whose vicinity they were now stationed. But two of them, having families at Darien, he ordered along with him. The Highlanders were not wholly engaged in military pursuits, for, to a great extent, they were engaged in making their settlement permanent. They engaged in the cultivation of Indian corn and potatoes; learned to cut and saw timber, and laid out farms upon which they lived. For a frontier settlement, constantly menaced, all was accomplished that could be reasonably expected. In the woods they found ripe oranges and game, such as the wild turkey, buffalo and deer, in abundance. But peace and prosperity were not their allotted portion, for their lines were now cast in troubled waters. The first year witnessed an appeal to arms and a struggle with the Spaniards, which eventually resulted in a disaster to the Highlanders. Deeds of heroism were now enacted, fully in keeping with the tenor of the race.
