The return for January, 1863, is taken from a captured Confederate plan showing position of the guns at that date, concerning which Captain M.D. McAlester, U.S. Engineers, says that he found some changes, but not material, when he inspected the works within a week after the surrender, and while nothing had yet been disturbed. January, 1864, is from reports of deserters to officers of United States fleets verified by reconnoissances from tugs on clear days and by reports of spies. The indications seem to be that the lighter guns were partially withdrawn, perhaps for the landward defences of Mobile, and their place supplied by heavier and rifled guns. The estimate in the text gives for all the forts one hundred cannon, including flank howitzers. General Grant's report as Commander-in-Chief, December, 1864, says one hundred and four pieces of artillery were taken; there were a few field pieces.
