For days there had been unusual activity in the camp. The Fourth of July was to be celebrated by a general bombardment; and if there were signs of yielding, a sharp assault and an attempt to capture the city would be made. The besieged party was not in ignorance of what was going on. The pickets and sharpshooters, and the soldiers at points where the fortifications touched each other, had given the whole programme of a grand Fourth of July celebration in boastful proclamations. Everything was at fever-heat on the 3d of July, though the firing was kept up at the usual rate till about one or two P.M. Suddenly all firing ceased. The silence could almost be felt. There had been pauses before, lasting an hour or more, during interviews under a flag of truce. But as the afternoon slowly wore away, and the firing was not resumed, the excitement became intense. Later, it was reported that General Grant and General Pemberton had met under a great spreading oak-tree just inside the Union lines, and that General Grant had made his terms known in the memorable phrase “_unconditional surrender_.” It was a sad hour for Pemberton. His army was starving; his ammunition and his fighting force were so diminished that to continue the siege seemed madness. And yet he had held out so long hoping help might come--it might now be near him--that it was hard to surrender. His was a fearful struggle. Not many words passed between these two men as they stood there, a little apart from their staff officers. Later, the time of the surrender was fixed at 9 A.M. on the Fourth of July, which was the next morning. The news flew through the camp at lightning speed. Soon everybody, sick and well, knew that Vicksburg had surrendered. The firing had ceased, but on both sides every man stood at his post. There was little sleep for any of us that night; the stillness was so unusual and impressive, and the excitement so intense, that sleep fled. The morning of the Fourth dawned fair and beautiful. Very early in the morning, in company with Dr. Maxwell and Mrs. General Stone, I drove out to General Logan’s headquarters, whence the army was to begin the triumphant march into the city.
