CUMMINGS POINT IRON BATTERY.
The nearest point of land to Fort Sumter is Cummings Point, distant 1,150 yards. On this point was the celebrated railroad iron battery, having a heavy framework of yellow pine logs. The roof was of the same material, over which dovetailed bars of railroad iron of the T pattern were laid from top to bottom—all of which was riveted down in the most secure manner. On the front it presented an angle of about thirty degrees. There were three port-holes, which opened and closed with iron shutters of the heaviest description. When open, the muzzles of the columbiads filled up the space completely. The recoil of the gun enabled the shutters to be closed instantly. The columbiad guns, with which this novel battery was equipped bore on the south wall of Sumter, the line of fire being at an angle of about thirty-five degrees.
The Fort Johnson batteries consist of two large sand works, containing mortar and siege-gun batteries.
