An attempt to assault the city was frustrated by the six galliots in the harbor. They, if any, were the heroes in the engagement. The English garrison left at Fort Moosa was cut to pieces by Montiano. Oglethorpe's plan for an assault now gave way to a siege.1 [Note 1 For English accounts of Oglethorpe's attack on San Agustin, see Stevens, History of Georgia, I, 171-179; Wright, Memoir, 243-260; Harris, Voyages and Travels, II, 339-340; Jones, History of Georgia, I, chs. 20-21. For the Spanish version, see Montiano's correspondence with Guemes, Ga. Hist. Soc. Col., vol. VII, Pt. I, 54-65.] Batteries on Santa Anastasia Island bombarded the town, but without effect. Starvation promised to be a more deadly weapon, but Spanish supply ships eluded the besiegers and relieved the famine. The task of the English was hopeless now, and on July 20 they raised the siege. Oglethorpe had repeated Moore's failure of forty years before. In old San Agustin there was rejoicing.
