(Jones) On the 12th, in the morning, the General sent into the fort a Spanish prisoner with terms for a possible surrender. The garrison agreed to surrender according to the terms set by Oglethorpe. They marched out; the garrison consisted of 50 men, amongst which was Don Diego Espinsoa. Lieutenants Dunbar and Sausere entered the fort and took possession, finding the place defended with nine Swivel Guns and two carriage mounted Two-Pounders. They then discovered that the fortification was known as "Fort Diego". The General ordered a ditch to be dug around Fort Diego. Then leaving a few troops to guard the place, he marched South to continue the assault on St. Augustine. Fort Moosa, located two miles North of St. Augustine, was found to be abandoned and the troops took possession of the place. Later the General placed Colonel Palmer in command.(The St. Augustine Expedition of 1740, The Colonial Records of South Carolina, (Columbia, South Carolina: 1954) The General then caused a battery of cannon to be placed on Anastasia Island and began shelling Fort San Marcos. The gunners complained, however, that each time they fired the guns, the carriages sank into the soft sand, making it necessary to realign the pieces before firing again.
