Among Satouriva’s tribe was a white child, a refugee from Laudonnère’s colony, who had escaped at the massacre at Fort Carolin, and been protected and reared as a son by the old chief, though the Spaniards had made strenuous efforts to secure possession of him or compass his death. This child, named Peter de Bré, whom Satouriva had so faithfully defended, he now brought to the French ships together with his warriors as he had agreed. Being joined by the Indians, De Gourges set out across the country under the guidance of the chief, Helecopile, to attack the two forts at the mouth of the river. The Indians had promised to bring the command to the fort on the north side of the river by daybreak, but, owing to the difficulty in following the intricate paths and fording deep creeks, they were nine hours marching four leagues, and the sun was rising as they reached the vicinity of the Spanish fort. This fort was built on Batton Island, near what is now Pilot-town. The other fort was nearly opposite, in the vicinity of the present village of Mayport. Both were armed with the cannon taken from the French at the capture of Fort Carolin. The Spaniards, not fearing a land attack upon the fort on Batton Island, had neglected to clear away the woods in the vicinity, so that the French were concealed until they were close upon the fort. As they rushed from their cover the Spanish sentinel fired twice, when he was pierced by the pike of Olotoraca, an Indian chief, nephew of Satouriva. The Spanish garrison were at breakfast, and before they could be summoned the fort was filled with the French and Indians. So complete was the surprise that there was but little resistance. “As many as possible were taken alive by command of Captain Gourges, in order to do to them as they had done to the French.” As soon as the Spaniards whose lives were spared in the attack could be secured, De Gourges embarked as large a portion of his soldiers as the boats at his disposal would carry, and hurried to cross the river and attack the fort at Mayport. The Indians, now wild with excitement, threw themselves into the water and kept alongside of the boats, swimming with their bows and arrows held above their heads. The Spaniards in the fort had by this time begun to realize the situation, and directed the fire of their guns upon the boats and Indians. Their excitement and alarm were so great that they did not perceive a difference between the French and Indians, and seeing so great a multitude approaching, they broke in terror and fled from the fort before the French reached its walls. The garrison of the two forts was near a hundred and forty men, all but fifteen of whom were either killed in the attacks or slain by the Indians as they attempted to reach the mainland.
