Indian attacks became so serious as to cause the removal of the settlement to another site. One night, when Menéndez was absent on an exploring trip, yelling savages broke through the Spanish lines at St. Augustine, and set fire to the storehouse with flaming arrows, destroying precious powder and supplies. When Menéndez returned he called a council of his officers. “It was resolved that they should move from there and erect a fort at the entrance of the bar ... because there the Indians could not do them so much harm ... and there they could better defend themselves against the vessels of enemies that might want to enter the harbor.” Working in shifts, the Spaniards rushed the construction of a stockade and fort at the new location. During the summer of 1566, the lonely Florida settlers were heartened by the arrival of substantial reinforcements. A fleet of fourteen vessels under Sancho de Arciniega brought 1,500 persons and welcome supplies. Part of this force was assigned to bolster the Florida garrisons. Menéndez was ordered to employ the remainder against pirates, or corsairs, who were plundering Spanish shipping and colonies in the Caribbean. By this time, in accordance with the terms of his contract. Menéndez had established three fortified posts in Florida—St. Augustine in about its present location, San Mateo near the mouth of the St. Johns River, and Santa Elena still farther north on the coast of Carolina. He had thoroughly explored the Florida coasts, and gone up the St. Johns River almost to its source. He had traveled among the Indians of South Florida, and of _Guale_, or southeastern Georgia, endeavoring to win their friendship and subject them to Spanish authority. One of his lieutenants, Juan Pardo, had penetrated inland with a few soldiers a distance of 450 miles to the mountains of western North Carolina. Possibly always in the back of his mind lurked the hope that he might come upon some news of his lost son and once more embrace him in his arms. _Menéndez Goes to Spain_ In 1567 Menéndez deemed it necessary that he go back to Spain to render in person a report on the condition and needs of the Florida and West Indian colonies. The little garrison at St. Augustine continued to cling precariously to its narrow beach-head. In the spring of 1568 the settlement shuddered when a small French force under Dominique de Gourges, aided by Indians, wiped out the Spanish posts near the mouth of the St. Johns. Captured Spaniards were hanged from the limbs of the liveoaks in revenge for the Frenchmen killed at Fort Caroline and Matanzas three years before. _On the Brink of Failure_ During Menéndez’ continued absence in Spain, the condition and morale of Florida posts grew steadily worse. Supplies were dangerously low, clothing was worn to shreds, and the shelters thus far constructed afforded little comfort. Efforts to grow corn and other grains in the sandy soil resulted in discouraging failure.
