During his temporary absence on this pressing emergency, Captain Antonio Barba, and two other Captains with one hundred grenadiers, and two hundred foot, besides Indians and negroes, advanced from the Spanish camp into the savannah with drums and huzzas, and halted within an hundred paces of the position where the troops left by Oglethorpe lay in ambuscade. They immediately stacked their arms, made fires, and were preparing their kettles for cooking, when a horse observed some of the concealed party, and, frightened at the uniform of the regulars, began to snort. This gave the alarm. The Spaniards ran to their arms, but were shot down in great numbers by their invisible assailants; and, after repeated attempts to form, in which some of their principal officers fell, they decamped with the utmost precipitation, leaving the camp equipage on the field. So complete was the surprise, that many fled without their arms; others, in a rapid retreat, discharged their muskets over their shoulders at their pursuers; and many were killed by the loaded muskets that had been left on the ground. Generally the Spaniards fired so much at random, that the trees were pruned by the balls from their muskets.[1] [Footnote 1: McCALL's _History_, I. 185.] The General, returning with all expedition, heard the report of the musketry, and rode towards it; and, near two miles from the place of action, met some platoons, who, in the heat of the fight, the air being so darkened by the smoke that they could not see where to direct their fire, and a heavy shower of rain falling, had retired in disorder. He ordered them to rally and follow him, apprehending that immediate relief might be wanting. He arrived just as the battle ceased; and found that Lieutenant Sutherland, with his platoon, and Lieutenant Charles Mackay, had entirely defeated the enemy. In this action Don Antonio de Barba, their leader, was made a prisoner, but mortally wounded. "In both actions, the Spaniards lost four captains, one Lieutenant, two sergeants, two drummers, and more than an hundred and fifty privates. One captain, one corporal, and twenty men were taken prisoners. The rest fled to the woods, where many of them were killed by the Indians, who brought in their scalps."[1] [Footnote 1: From the great slaughter, the scene of this action has ever since been called "the bloody marsh."]
