The negroes were principally exposed to the bombardment. The only time the few Confederate soldiers were exposed to danger was while they were putting the Chevaldefrise on the parapet at night. The "Chevaldefrise" is a piece of timber with wooden spikes pointed with iron, and used for defence on fortifications. In the late war between the Spaniards and the Americans, the former used barbed wire for the same purpose. If my readers could have been in Fort Sumter in the summer of 1864 they would have heard the sentinel cry, every five minutes, "Look out! Mortar!" Then they would have seen the negroes running about in the fort yard in a confused state, seeking places of safety from the missile sure to bring death to one or more of them. Another five minutes, and again the cry of the sentinel, "Look out," means a parrot shell, which is far more deadly than is the mortar because it comes so quickly that one has no chance to seek a place of safety. The next moment the survivors of us, expecting that it would be our turn next, would be picking up, here and there, parts of the severed bodies of our fellow negroes; many of those bodies so mutilated as not to be recognizable. DEBURGH, THE OVERSEER. Deburgh, the overseer, of whom I have spoken, was a small man, of light complexion, and very light hair. If my readers could have been in Fort Sumter in July, 1864, they would have seen Deburgh with a small bar of iron or a piece of shell in his hand, forcing the surviving portion of the negroes back into line and adding to these, other negroes kept in the Rat-hole as reserves to fill the places of those who were killed and wounded. They would also have heard him swearing at the top of his voice, while forcing the negroes to rearrange themselves in line from the base of the fort to the top. This arrangement of the negroes, enabled them to sling to each other the bags of sand which was put in the baskets on the top of the fort. My readers ask, what was the sand put on the fort for? It was to smother the fuses of such shells as reached the ramparts before bursting. After the bombardment of Port Sumter in 1863, by the Union forces, its top of fourteen or sixteen feet in thickness, built of New Hampshire granite, was left bare. From that time all through 1864, the shells were so aimed as to burst right over the fort; and it was pieces of these shells which flew in every direction that were so destructive. The fuses of many of these shells fired on Port Sumter did not burn in time to cause the shells to burst before falling. Now as the shells fell on the rampart of the fort instead of falling and bursting on the stone, they buried themselves harmlessly in the sand, which put out the fuse and also kept them from bursting.
