At dawn the cannonading began anew and lasted all day. Musketry, too, volleyed and rolled. The Federal ammunition never lacked, but the grey were in no position to spend with freedom. Every ridge of the besieging line belched saffron flame, thick smoke, and thunder; every point of vantage sent its stream of minies, horribly singing. On this day the blue began sap after sap. In the night-time the grey sent a detachment from Stevenson’s right out upon the river flats, their errand the constructing of an abatis against a possible blue approach that way. A Federal party came against them and there was a bitter skirmish. The gunboats, excitedly waking, thrust a duel upon the river batteries. The night flamed and roared. The grey won out upon the flats and returned with a hundred prisoners. The morning saw the river fight and the sinking of the Cincinnati. May shook and thundered toward its sulphurous close. The twenty-ninth, thirtieth, and thirty-first were marked by a continuous, frightful bombardment. By now the blue parallels were close, close to every main grey work. They were very close, indeed, to the Third Louisiana Redan. All night the grey engineers and their haggard men dug, dug to repair the daytime breaches, to make inner lines. On the first day of June fire broke out in the town. There threatened a general conflagration, but soldiers and civilians conquered the flames before there was disaster irretrievable. The weather was deadly hot. Fever became epidemic. There arrived a question of musket caps. Imperatively needed, they must be had. If it were possible for a few daring men to get down the river and across, behind the enemy, to Jackson, General Johnston would send the caps. There were volunteers. Captain Saunders, Lamar Fontaine, a courier named Walker, were the first chosen; later, a noted scout and Lieutenant Edward Cary. At midnight they drifted down the river on logs. The battery under whose shadow they had set out listened for a shout, looked for a leaping flame from some one of the gunboats they must pass. But the gunboats lay silent. There was always driftwood upon the rushing river. At dawn the mortars on the Louisiana side began to shell the batteries and the town beyond. Later the gunboats took a hand. Six days in succession this bombardment opened with the first light in the east and closed with the latest in the west. Vicksburg lost the last semblance of old times. The bombs ripped houses open as they ripped bodies. The blue began to drive double saps against the principal redans. The grey began to countermine. All the torn, sunbaked line knew that from now on it would stand over volcanoes. Désirée went into the town and to the hospitals, but when she found there were nurses enough she was glad—though, had there been need, she like all the rest would have worked there until she dropped.
