"Soon," says Greeley in his History, "the thunder of fifty heavy breaching cannon, in one grand volley, followed by the crashing and crumbling of brick, stone, and mortar around and above them, apprized the little garrison that their stay must necessarily be short." Says an eye-witness of the bombardment: "Shells burst with the greatest rapidity in every portion of the work, hurling the loose brick and stone in all directions, breaking the windows and setting fire to whatever woodwork they burst against. * * * The firing from the batteries on Cumming's Point was scattered over the whole of the gorge or rear of the Fort, till it looked like a sieve. The explosion of shells, and the quantity of deadly missiles that were hurled in every direction and at every instant of time, made it almost certain death to go out of the lower tier of casemates, and also made the working of the barbette or upper (uncovered) guns, which contained all our heaviest metal, and by which alone we could throw shells, quite impossible. "During the first day there was hardly an instant of time that there was a cessation of the whizzing of balls, which were sometimes coming half a dozen at once. There was not a portion of the work which was not taken in reverse from mortars. * * * During Friday, the officers' barracks were three times set on fire by the shells and three times put out under the most galling and destructive cannonade. "For the fourth time, the barracks were set on fire early on Saturday morning, and attempts were made to extinguish the flames; but it was soon discovered that red-hot shot were being thrown into the Fort with fearful rapidity, and it became evident that it would be impossible to put out the conflagration. The whole garrison was then set to work, or as many as could be spared, to remove the powder from the magazines, which was desperate work, rolling barrels of powder through the fire. * * * After the barracks were well on fire, the batteries directed upon Fort Sumter increased their cannonading to a rapidity greater than had been attained before." "About this time, the shells and ammunition in the upper service-magazines exploded, scattering the tower and upper portions of the building in every direction. The crash of the beams, the roar of the flames, and the shower of fragments of the Fort, with the blackness of the smoke, made the scene indescribably terrific and grand. This continued for several hours. * * * " "There was not a portion of the Fort where a breath of air could be got for hours, except through a wet cloth. The fire spread to the men's quarters on the right hand and on the left, and endangered the powder which had been taken out of the magazines. The men went through the fire, and covered the barrels with wet cloths, but the danger of the Fort's blowing up became so imminent that they were obliged to heave the barrels out of the embrasures."
