Having been apprized of this, the General, apprehending that the Spaniards had in view some formidable expedition against Georgia or Carolina, or perhaps both, wrote to the Commander of his Majesty's ships, in the harbor of Charlestown, urging him to come to his assistance. Lieutenant Maxwell, the bearer, arrived and delivered the letter on the 12th of June. Directly afterwards he sent Lieutenant Mackay to Governor Glenn, of South Carolina, requesting his military aid with all expedition; and this despatch reached him on the 20th. He then laid an embargo upon all the shipping in Georgia; and sent messages to his faithful Indian allies, who gathered to his assistance with all readiness. And now the design of the Spaniards was manifest. On the 21st of June the fleet appeared on the coast; and nine sail of vessels made an attempt on Amelia Island, but were so warmly received by the cannon from Fort William, and the guard-schooner of fourteen guns and ninety men, commanded by Captain Dunbar, that they sheered off. When the General was informed of this attack, he resolved to support the fortifications on Cumberland Island; and set out with a detachment of the regiment in three boats; but was obliged to make his way through fourteen sail of vessels. This was very venturesome, and, indeed, was considered as presumptuously hazardous. For, had a shot from one of the galleys struck the boat in which he was, so as to disable or sink it, or had he been overtaken by a gun-boat from the enemy, the colonial forces would have become the weakly resisting victims of Spanish exasperated revenge. But by keeping to the leeward, and thus taking advantage of the smoke, he escaped the firing and arrived in safety. After having withdrawn the command from St. Andrews, and removed the stores and artillery that were there, and reinforced Fort William,[1] where he left one of the boats, he returned to St. Simons. [Footnote 1: These two Forts were on Cumberland Island.] He now sent another express to the Governor of South Carolina, by Mr. Malryne, informing him of his situation, and urging the necessity of a reinforcement. This application was not promptly complied with, in consequence of an unfortunate prejudice arising from the failure of his attempt upon St. Augustine. But as Georgia had been a great barrier against the Spaniards, whose conquest of it would be hazardous to the peace and prosperity of South Carolina, "it was thought expedient to fit out some vessels to cruise down the coast, and see what could be done for its relief."[1] [Footnote 1: WILLIAMS's _History of Florida_, p. 185.]
