Spanish forces overwhelmed the colonists by their superior numbers, when the veteran troops became seized with a panic. They made a precipitate retreat, the Highlanders following reluctantly in the rear. After passing through a defile, Lieutenant MacKay communicated to his friend, Lieutenant Southerland, who commanded the rear guard, composed also of Highlanders, the feelings of his corps, and agreeing to drop behind as soon as the whole had passed the defile. They returned through the brush and took post at the two points of the crescent in the road. Four Indians remained with them. Scarcely had they concealed themselves in the woods, when the Spanish grenadier regiment, the _elite_ of their troops, advanced into the defile, where, seeing the footprints of the rapid retreat of the broken troops, and observing their right was covered by an open morass, and their left, as they supposed, by an impracticable wall of brushwood, and a border of dry white sand, they stacked their arms and sat down to partake of refreshments, believing that the contest for the day was over. Southerland and MacKay, who, from their hiding places, had anxiously watched their movements, now from either end of the line raised the Highland cap upon a sword, the signal for the work of death to begin. Immediately the Highlanders poured in upon the unsuspecting enemy a well delivered and most deadly fire. Volley succeeded volley, and the sand was soon strewed with the dead and the dying. Terror and dismay seized the Spaniards, and making no resistance attempted to fly along the marsh. A few of their officers attempted, though in vain, to re-form their broken ranks; discipline was gone; orders were unheeded; safety alone was sought; and, when, with a Highland shout of triumph, the hidden foe burst among them with levelled musket and flashing claymore, the panic stricken Spaniards fled in every direction; some to the marsh, where they mired and were taken; others along the defile, where they were met by the claymore, and still others into the thicket, where they became entangled and perished; and a few succeeded in escaping to their camp. Barba was taken, though mortally wounded. Among the killed were a captain, lieutenant, two sergeants, two drummers and one hundred and sixty privates, and a captain and nineteen men taken prisoners. This feat of arms was as brilliant as it was successful. Oglethorpe, with the two platoons, did not reach the scene of action, since called the "Bloody Marsh," until the victory was won. To show his sense of the services rendered, he promoted the brave young officers who had gained it on the very field of their valor. But he rested only for a few minutes, waiting for the marines and the reserve of the regiment to come up; and then pursued the retreating enemy to within a mile and a half of their camp. During the night the foe retreated within the ruins of the fort, and under the protection of their cannon. A few days later the Spaniards became so
