At Vicksburg, during the whole six weeks of the siege, the men in the trenches worked steadily, advancing the coils about the city. Grant received reenforcement and before the end of the siege his army numbered over seventy thousand. Day and night, the roar of artillery continued. From the mortars across the river and from Porter's fleet the shrieking shells rose in grand parabolic curves, bursting in midair or in the streets of the city, spreading havoc in all directions. The people of the city burrowed into the ground for safety. Many whole families lived in these dismal abodes, their walls of clay being shaken by the roaring battles that raged above the ground. In one of these dens, sixty-five people found a home. The food supply ran low, and day by day it became scarcer. At last, by the end of June, there was nothing to eat except mule meat and a kind of bread made of beans and corn meal.

It was ten o'clock in the morning of July 3d. White flags were seen above the parapet. The firing ceased. A strange quietness rested over the scene of the long bombardment. On the afternoon of that day, the one, too, on which was heard the last shot on the battlefield of Gettysburg, Grant and Pemberton stood beneath an oak tree, in front of McPherson's corps, and opened negotiations for the capitulation. On the following morning, the Nation's birthday, about thirty thousand soldiers laid down their arms as prisoners of war and were released on parole. The losses from May 1st to the surrender were about ten thousand on each side.

Three days later, at Port Hudson, a tremendous cheer arose from the besieging army. The Confederates within the defenses were at a loss to know the cause. Then some one shouted the news, “Vicksburg has surrendered!”

The end had come. Port Hudson could not hope to stand alone; the greater fortress had fallen. Two days later, July 9th, the gallant garrison, worn and weary with the long siege, surrendered to General Banks. The whole course of the mighty Mississippi was now under the Stars and Stripes.
