FORT SUMTER, S.C., March 5, 1861.
Col. S. COOPER, Adjutant-General:
COLONEL: I have the honor to report that parties are working to-day on the mortar battery at Fort Johnson, which they are making higher and stronger, and on the Morris Island batteries, numbered on Captain Seymour’s sketch Nos. 1, 9, and 10. They are filling the embrasures in this last battery, in which we see that one gun has been placed. They are also at work on the covered way connecting Nos. 9 and 7.
I presume, from the movements around us yesterday, that Brig. Gen. P. G. T. Beauregard assumed command and made an inspection of the forts, &c., in this harbor, which are garrisoned by the South Carolina troops.
I am, colonel, very respectfully, your obedient servant,
ROBERT ANDERSON,
Major, First Artillery, Commanding.
