In the meantime, the undaunted Oglethorpe had once more decided to challenge the Spanish neighbor in Florida, and encouraged by the British authorities marched upon St. Augustine. He had six hundred regular troops, four hundred militia from Carolina and two hundred Indians, and set out on his expedition in January, 1740. But the garrison of the old town, under the command of the able Monteaco, was prepared and had also secured reenforcements. Five weeks lasted the siege; the troops of Oglethorpe lost patience and courage, failure staring them in the face. When they threatened to abandon him, he retired without even being pursued by the enemy. After this provocation the Spanish authorities felt forced to retaliate and decided upon an invasion of Georgia. A large fleet with troops from Cuba joined the forces of the Florida settlement. They arrived at the mouth of St. Mary's, where Oglethorpe had built Ft. William, in the first days of July. But Oglethorpe succeeded in retaining his hold upon that place, though his forces had to retire. The Spanish took possession of their abandoned camps, but on the seventh of July, when they were attempting to advance towards the town on a road which skirted a swamp on one side and a dense wood of brush-oak on the other, they were surprised by Oglethorpe and the fight which ensued was so fierce, and caused such a great loss of life, that the spot has ever since been known as Bloody Marsh. Another attack was made upon Fort William, but being again repulsed, the Spanish forces retired, abandoning a quantity of ammunition. When Guemez of Cuba was promoted to the vice-regency of New Spain, he had been succeeded by Field Marshal D. Juan Antonio Tines y Fuertes, who was inaugurated on the twenty-second of April, 1746, but died on the twenty-first of July of the same year. In spite of his very brief term of service, he is remembered according to Valdes for having been the first governor to whom it occurred to do something for the confinement and possible reform of dissolute women. He is said to have founded for that purpose the Casa de Resorgimento, which seems to have been both a home and a reform school. He was temporarily replaced by Colonel D. Diego de Penalosa. About the name and exact date of his interim administration there seems to exist some confusion, some historians placing him immediately after Martinez de la Vega. Valdes says he was Tenente-Rey in 1738, assumed the functions of provisional governorship at the death of Fuentes, and upon the arrival of the newly appointed governor, was sent to Vera Cruz as Brigadier General. Blanchet, too, calls him Penalosa; but Alcazar gives his name as Penalver. However, Penalosa or Penalver enjoyed during his brief administration the privilege of proclaiming the ascension of Fernando VI. to the throne of Spain.
