Dropping down to Fernandina unmolested after this affair, we were kindly received by the military and naval commanders,--Colonel Hawley, of the Seventh Connecticut, (now Brigadier-General Hawley,) and Lieutenant-Commander Hughes, U. S. N., of the gunboat Mohawk. It turned out very opportunely that both of these officers had special errands to suggest still farther up the St. Mary's, and precisely in the region where I wished to go. Colonel Hawley showed me a letter from the War Department, requesting him to ascertain the possibility of obtaining a supply of brick for Fort Clinch from the brickyard which had furnished the original materials, but which had not been visited since the perilous river-trip of the Ottawa. Lieutenant Hughes wished to obtain information for the Admiral respecting a Rebel steamer--the Berosa--said to be lying somewhere up the river, and awaiting her chance to run the blockade. I jumped at the opportunity. Berosa and brickyard,--both were near Woodstock, the former home of Corporal Sutton; he was ready and eager to pilot us up the river; the moon would be just right that evening, setting at 3h. 19m. A. M.; and our boat was precisely the one to undertake the expedition. Its double-headed shape was just what was needed in that swift and crooked stream; the exposed pilot-houses had been tolerably barricaded with the thick planks from St. Simon's; and we further obtained some sand-bags from Fort Clinch, through the aid of Captain Sears, the officer in charge, who had originally suggested the expedition after brick. In return for this aid, the Planter was sent back to the wharf at St. Mary's, to bring away a considerable supply of the same precious article, which we had observed near the wharf. Meanwhile the John Adams was coaling from naval supplies, through the kindness of Lieutenant Hughes; and the Ben De Ford was taking in the lumber which we had yesterday brought down. It was a great disappointment to be unable to take the latter vessel up the river; but I was unwillingly convinced, that, though the depth of water might be sufficient, yet her length would be unmanageable in the swift current and sharp turns. The Planter must also be sent on a separate cruise, as her weak and disabled machinery made her useless for my purpose. Two hundred men were therefore transferred, as before, to the narrow hold of the John Adams, in addition to the company permanently stationed on board to work the guns. At seven o'clock on the evening of January 29th, beneath a lovely moon, we steamed up the river.
