Meantime a serious danger threatened the colony. In 1736, the Spaniards, who had long viewed Georgia with suspicion, made an armed reconnaissance, but nothing could be done, for there was at that time no war between the two countries in Europe. It was not until 1739 that Walpole was forced by popular demand to declare war against Spain, an act which he regarded with disgust as contrary to all his principles and desires. Georgia was in a particularly exposed position with regard to Spanish aggression, and Oglethorpe decided to take the offensive as a defensive measure and carry the war into the enemy's country. Reading the signs of the times and knowing what was hatching in Europe, the English Governor collected a force of about 600 volunteers and boldly marched for Florida in October 1738. He had been partly led to this action by the fact that news had been brought that the Spanish troops had been increased in St Augustine, and that the civil inhabitants had been turned out of their houses to give quarters to the royal forces. Oglethorpe's move was an unsatisfactory one, not through want of bravery on his part, but rather because he was a poor judge of men and his soldiers were wanting in the spirit of loyalty; some had even concerted a plot with the Spanish, while others had actually deserted to the enemy. Nothing daunted, Oglethorpe spent the summer of 1739 securing the alliance of most of the neighbouring Indian tribes, and when war was formally declared against Spain the Georgian Governor was in a better position for whatever fate might have in store.
