BATTERY WAGNER, August 21, 1863.

I have the honor to make the following report as to the present condition of Battery Wagner:

The parapets this work are in as good condition to-day as at any time since I have been on duty at the post. I consider all the magazines and bomb-proofs secure from direct or vertical fire, the guns all in working condition, with the exception of 10-inch columbiad in northernmost chamber. It requires a working party of 200 men, every night, and 1,000 sand-bags to keep the fort up to its present standard.

I have the honor to be, captain, very respectfully, your obedient servant,

J. W. GREGORIE,

Captain of Engineers, in Charge Defenses Morris Island.

Captain P. K. MOLONY,

Assistant Adjutant-General.

BATTERY WAGNER, August 22, 1863.

CAPTAIN: The engineer works were pushed forward last night with 100 men.

I repaired sea face, which was sadly torn up by the Ironsides, also traverse over southeast magazine, which was nearly cut through; repaired embrasure on salient, and erected merlons for the protection of the men at the guns. Commenced on traverse before the door of southwest magazine.

I have the honor to be, captain, very respectfully, your obedient servant,

J. W. GREGORIE,

Captain of Engineers.

Captain MOLONY,

Assistant Adjutant-General.
