Night and day, Gillmore’s batteries maintained a “slow fire” against Fort Sumter throughout November and into December. On occasion the monitors assisted. Sumter could return merely “harmless musketry”; only telescopic rifle sights made even that much possible. But, the “rebels” seemed “snug in the ruins”; and if Sumter was without guns, Confederate batteries on James and Sullivan’s Islands kept up an irritating counterfire. [Illustration: Capt. John C. Mitchel. From Johnson, The Defense of Charleston Harbor.] [Illustration: Capt. Thomas A. Huguenin. From Johnson, The Defense of Charleston Harbor.] On November 6, the Confederate engineer at Fort Sumter reported the bombproofs (quarters) unhurt. Although the height of the mass of the fort was “diminishing visibly on the sides away from the city,” still, “when it gets down to the lower casemates [he wrote] it will have become so thick from accumulated debris as to resist further battering.” Two weeks later, Major Johnson found the fort stronger than ever, and casualties were “either among those carelessly exposing themselves, outside the bombproof, or obliged to do so when at work.” Indeed, casualties had been surprisingly low—only 2 men had been killed in the bombardment of August and only 22 more since the start of the second great bombardment; 118 had been wounded. Major Johnson did not “apprehend being run out by the big guns”; his chief anxiety was over “exposure to assault from barges at night.” In mid-November such an attack seemed to be forthcoming. During the early hours of the 18th, the defenders of the fort had “four distinct alarms” as small boats approached within hailing distance; “all hands out each time and expecting a fight.” On the following night, a force estimated at 250 men approached within 300 yards of the fort, only to be driven off by the muskets of the aroused garrison. But General Gillmore had merely ordered a “reconnaissance ... of the nature of a simulated attack, with a view to compel the garrison to show its strength.” Nor would he make another attempt. The next move remained up to the Navy.
