General,—Before leaving, on my return to
Charleston, I think it advisable to leave with you a summary of the additions and changes I have ordered to the works intended for the defence of this city, and which ought to be executed as promptly as practicable, commencing with those on the river and at Caustine's Bluff:
1. The magazines of several of the river batteries must be thoroughly drained at once, and repaired.
They are now unfit for use, on account of their dampness, and the one at Battery Lawton has not yet been commenced.
The position selected for it is too far to the rear.
It should be closer to the battery, and well drained.
Not a moment should be lost in its construction.
The service magazine should have its entrance enlarged and strengthened at the top. The magazine doors at Fort Jackson do not open freely.
This defect must be corrected.
2. Good and strong traverses must be constructed, as directed, in the Naval Battery, to prevent enfilading.
3. The two 8-inch columbiads on Fort Jackson must be separated, and one of the barbette 32-pounders (removed, for a traverse to be constructed in its place) must be put in position outside, in rear of the glacis, to fire down the river.
4. Those river works, when garrisoned, must always be provided with several days' provisions on hand.
5. The mortar-chamber in Capt. Lamar's battery is too small.
The mortars should be mounted as soon as practicable, and the men drilled to it.
6. It would be important, if possible, to lay a boom obstruction across the river, at or near Hutchinson's Island, under the guns of its battery, and of Fort Boggs, and a three or four gun battery should also be constructed at Screven's Ferry Landing.
7. Caustine's Bluff must be made an enclosed work, with two mortars and four heavy guns added to its armament.
Two of these guns must be placed so as to bear up the Augustine River.
8. A three-gun battery must be constructed at Greenwich Point, on
