During these years the fort was not without service, however. In 1702 and again in 1740 San Augustin was attacked by English forces from the English colonies to the north, and Fort San Marco, even while not complete, bore the brunt of these attacks. The second expedition against San Augustin was under the leadership of Governor Oglethorpe, of Georgia, and arose to the dignity of a siege of the city. For weeks the English forces lay beyond the city walls and were then driven off by reinforcements brought from Cuba. With the construction of Fort San Marco the erection of city walls was undertaken, too. The walls of old San Augustin ran from Fort San Marco around the city and were constructed of “coquina.” Only the so-called “City Gate” remains of these walls to-day. In 1763 the warrior which had withstood armed assault fell to the attack of diplomacy, for it was in this year that England made its trade with Spain whereby Spain was given back Cuba, which England had wrested by force of arms from that country, and England was given Florida. The flag of Castile and of Aragon was hauled down from the wall of the old fort and the British lion was raised in its place. Fort San Marco became in British hands Fort St. Mark. During the American revolution Florida was the only one of the fourteen British colonies which remained loyal to the Mother Country. The fervor of the northern coasts found no kindred spark in old St. Augustine. The town became a haven for Tories. She opened her gates and an oddly-assorted throng came flocking in. There was the Tory colonel Thomas Browne, of Georgia, tar and feathers still sticking to his skin from his experience with the Liberty Boys, of Savannah. There was Rory McIntosh, always attended by Scotch pipers, who paraded the narrow streets breathing out fire and slaughter against the colonies. The Scopholites, so-called from Scophol, their leader, marched down, 600 strong, from the back country of North Carolina, burning and killing in their course through Georgia. With such additions, St. Augustine was not content with passive loyalty and became a centre for military operations against the southern colonies. Many a council did the rooms of Fort St. Mark witness, which had as its result death and privation to the rebellious Americans. Two expeditions were attempted by the colonists against Fort St. Mark. The first under General Charles Lee fell short because of mismanagement. The second advanced as far as the St. John’s River. Consternation in St. Augustine reigned supreme; slaves were impressed to help strengthen the fortifications; citizens ran hither and thither with their valuables. But the Americans were menaced by fever at the St. John’s and faced the prospect of a midsummer encampment in Florida, so they turned about and went north. Fort St. Mark was not to leave English hands by force.
