The agent reported that his party had had many adventures, but had finally reached St. Augustine, where Don Francisco, the governor, had welcomed them and given them letters for Oglethorpe, asking for an answer in three weeks.

The expedition returned to Frederica, where the governor read his men the contents of the Spaniard's letters. These were full of flattering phrases, but there was also complaint that the Creeks had attacked Spaniards, and requests that Oglethorpe should restrain his Indian allies. The governor suspected that these requests were only a blind to hide a future attack by the Spaniards on the English colonists, but he was very anxious to avoid such trouble if it was possible, so he sent a boat of twenty oars, fitted out with swivel-guns, to patrol the St. Johns River and keep any Creek Indians from crossing to attack the Spaniards. He also stationed scout boats at other places, and asked Tomochichi to send word to the Creeks that their ally, the governor of Georgia, requested them not to make raids into Florida, but to keep guard on the mainland in the neighborhood of the settlement at Darien.

Soon after Oglethorpe returned to Savannah he saw that trouble was brewing with the Spaniards. He heard that a large troop of soldiers had lately marched from St. Augustine. He knew that there was a garrison of three hundred foot-soldiers and fifty horse at St. Augustine, with reinforcements coming from Havana, and that he had not a single regular soldier with which to oppose them. Then word came that a fleet of strange ships had been seen at sea. He ordered his colonists to strengthen their fort at once, and set out in a boat for St. Andrews to learn exactly how matters stood.

From Fort St. George he crossed to the Spanish side of the St. Johns River, and climbing a hill, fastened a white flag to a pole, hoping the Spaniards would come to a conference with him. None came, however, but fires were seen on the Florida side that night, and the governor thought the Spaniards were planning an attack. He ordered two gun-carriages and two swivel-guns taken into the woods and placed at different points. The larger guns were to fire seven shots, and the smaller to answer with five. The latter would sound like a distant ship firing a salute, and the larger guns would resemble the noise of a battery returning the salute. In this way Oglethorpe hoped to make the Spaniards think that reinforcements were coming to the aid of the Georgians.

By this trick Oglethorpe escaped great danger. As a matter of fact the Spanish governor had arrested Oglethorpe's messengers, and had sent a strong force to attack the fort on St. Simons Island. The battery there, however, drove the Spaniards out to sea again, and when they tried to approach by another inlet they were driven off the second time by the garrison at St. Andrews. They then decided to attack St. George, but as they were planning this they heard the booming of the distant cannon, thought reinforcements must be arriving, as Oglethorpe had figured on their thinking, and decided not to make the attack at all then.

At the same time Oglethorpe lighted fires in the woods, thereby making his enemy believe that Creek Indians were coming to join the English. The Spanish commander, Don Pedro, gave the order to return to the walls of St. Augustine, and there, by his reports of the numbers of Oglethorpe's troops, induced the Spanish governor to send back Oglethorpe's two agents, and with them one of his own officers to urge the Englishman to keep his Indian allies from invading Florida.

Oglethorpe, however, did not know that Don Pedro had returned to St. Augustine, and so, with twenty-four men, crossed the St. Johns River to the Spanish side, hoping to get word of his agents. He saw a Spanish boat with seventy men on board. The boat headed away at sight of the English colonists. Then two Spanish horsemen appeared and forbade the English landing on the soil of the king of Spain. Oglethorpe said that he would do as they wished, but he invited them to land on English ground if they desired and offered them wine should they come.

The governor now learned that men in Charleston were selling arms and ammunition to the Spaniards, regardless of the fact that the latter meant to use them against the former's own English neighbors. He wrote to men in South Carolina urging them not to allow this, but in spite of his protests the men of Florida continued for some time to draw a large part of their supplies from the colony to the north of Georgia.

Then he returned to Fort St. George, taking with him Tomochichi and his men in their canoes, a large barge, and two ten-oared boats with fifty soldiers, cannon, and stores for two months. On the way he heard that his agents were coming back accompanied by two Spanish officers. He did not want the Spaniards to learn the strength of his garrison, so he gave orders that they should be entertained on board his ship the Hawk, on the excuse that the country was full of Indians who might otherwise attack the Spaniards.

Tents were set up on Jekyll Island, the Scotchmen dressed in their plaids, the whole garrison assumed its most martial air, and Oglethorpe, attended by seven officers, embarked for the Hawk, his purpose being to impress the Spaniards with the size of his forces. The Spaniards were impressed; they promised on their part to right the wrongs that Oglethorpe's Indian allies complained of, and gained a promise from him in return that he would do his best to keep the Creeks and other tribes from molesting the Spanish settlers. Later, on his return to Savannah, the governor made a treaty with the Spanish governor. More and more bickering arose, however, between the settlers of the two nations, and so Oglethorpe sailed for England in November, 1736, hoping to win aid for his colony from the British government.
