Captain Henry and the naval department were employed, from the 10th to the 13th, in conveying to Savannah part of the guns and ammunition of the Rose and Fowey, in vessels which General Prevost had sent down for that purpose. On the 13th, both frigates being much lightened, sailed over the Mud-flat to Five Fathom Hole, from which the remainder of their guns and ammunition were conveyed up to the town, which is only three miles distant. The Comet galley, Keppel brig, and some armed vessels, were so placed as to cover the passage of Colonel Maitland, with the forces under his command, from Port Royal, through Wallscut. On the 14th and 15th, the seamen completed the important business of landing the cannon and ammunition from the ships and small vessels: and they were appointed to the different batteries, under the command of Captains Henry, Brown, and Fisher, of the navy. Some masters of transports, and the master of a privateer, with their men,[99] made voluntary offers of their service; as did Mr. Manley; merchant of Jamaica. Their offers were accepted; and they had their posts assigned them. The marines were incorporated with the grenadiers of the 60th regiment. On the 16th, the Compte d'Estaing sent a haughty letter to General Prevost, summoning him to surrender the place to his Most Christian Majesty: informing him, at the same time, that among the troops which he had the honour to command, was the detachment which had stormed the Hospital Hill at the Grenades. He begged leave to recal this to his memory; and assured him, that he gave him this notice from motives of humanity, in order to spare the shedding of human blood. General Prevost, on receiving this message, called a meeting of the Governor, Lieutenant-Governor, and Field-Officers in the garrison, who authorised him to say, that he declined surrendering on a general summons, without specific terms; but that, if such were proposed as he could with honour accept, he would then give his answer. This drew a reply from M. d'Estaing, in which he affirmed, that it was customary, not for besiegers, but for those who were besieged, to propose terms of capitulation; stated, that he had no objections to allow the General every indulgence consistent with his duty; and informed him that, as it was his intention next day to form a junction with the army of the United States of America, if his answer was not immediately ready, he must in future treat with General Lincoln and him. General Prevost, in return, demanded a cessation of hostilities for 24 hours; as a time absolutely necessary for deliberation, and for the discussion of various interests. Towards the evening of the 16th, the Compte d'Estaing returned an answer, in which he consented to this demand. The two armies joined on the 17th, and formed separate but contiguous encampments.
