17. In February of 1736 Oglethorpe came back with a colony of three hundred. These were also Moravians, people of deep piety and fervent spirit. First among them was John Wesley, the founder of Methodism. He came to Georgia to spread the gospel and convert the Indians. But he was doomed to much disappointment in his work; and after a residence of less than two years he left the colony. His brother, Charles Wesley, came also as a secretary to Governor Oglethorpe. In 1738 the famous George Whitefield came, and preached with fiery eloquence through all the colonies. 18. Meanwhile, Oglethorpe, anticipating war with Florida, began to fortify. All of Georgia was embraced in the Spanish claim. But Oglethorpe had a charter for the territory as far south as the Altamaha. In 1736 he ascended the Savannah and built a fort at Augusta. On the north bank of the Altamaha, he built Fort Darien. On St. Simon's Island a fortress was erected and named Frederica. The St. John's was claimed from this time forth as the southern boundary of Georgia. The governor again visited England, and returned with a regiment of troops. [Sidenote: =War with Spanish Florida.=] 19. In October, 1739, England published a declaration of war against Spain. In the first week of the following January, Oglethorpe invaded Florida, and captured two fortified towns. Soon, with a force of more than a thousand men, he marched against St. Augustine, but after a siege of five weeks was compelled to withdraw. 20. The Spaniards now determined to carry the war into Georgia. In June of 1742 a fleet of thirty-six vessels, carrying more than three thousand troops, sailed from St. Augustine for the reduction of Fort William on Cumberland Island. But Oglethorpe reinforced the garrison, and then fell back to Frederica. The Spanish vessels followed. From the southern point of the island to Frederica, Oglethorpe had cut a road which lay between a morass and a forest. The Spaniards must pass along this path to attack the town. 21. The English general posted his men between the swamp and the forest. On the 7th of July the enemy reached the pass, were fired on from the thicket, and driven back in confusion. The main body of the Spanish forces pressed on into the same position, stood firm for a while, but were presently routed with the loss of two hundred men. The name of Bloody Marsh was given to this battlefield. Within a week the whole Spanish force reembarked and sailed for Florida. 22. The colony of Georgia was now firmly established. In 1743 Oglethorpe departed for England, after having devoted ten years to the colony. He had never owned a house nor possessed an acre of ground in the province.
