Having thus given vent to his feelings of exultation, in obedience to orders, he commenced the removal of his battery on board the Trenton. It was two days' work to accomplish this, but Frank, who was impatient to see the inside of the fortifications worked with a will, and finally the battery was mounted in its old position. On the following day, the Trenton moved down the river, and came to anchor in front of Vicksburg. Shore liberty was granted, and Frank, in company with several of his brother officers, strolled about the city. On every side the houses bore the marks of Union shot and shell, and the streets were blocked with fortifications, showing that had the city been taken by storm, it was the intention of the rebels to dispute every inch of the ground. Every thing bore evidence to the fact that the fight had been a most desperate one; that the rebels had surrendered only when they found that it was impossible to hold out longer. In some places the streets ran through deep cuts in the bank, and in these banks were the famous "gopher holes." They were [ca]ves dug in the ground, into which a person, if he happened to hear a shell coming, might run for safety. Outside the city, the fortifications were most extensive; rifle-pits ran in every direction, flanked by strong forts, whose battered walls attested the fury of the iron hail that had been poured upon them. It was night before Frank was aware of it, so interested was he in every thing about him, and he returned on board his vessel, weary with his long walk, but amply repaid by seeing the inside of what its rebel occupants had called "the Gibraltar of America." During the next two days, several vessels of the squadron passed the city, on their way to new fields of action further down the river. One of them--the Boxer, a tin-clad, mounting eight guns--had Frank on board. He had been detached from the Trenton, and ordered to join this vessel, which had been assigned a station a short distance below Grand Gulf. As usual, he had no difficulty in becoming acquainted with his new messmates, and he soon felt perfectly at home among them. He found, as he had done in every other mess of which he had been a member, that there was the usual amount of wrangling and disputing, and it amused him exceedingly. All the mess seemed to be indignant at the caterer, who did not appear to stand very high in their estimation. The latter, he learned, had just made an "assessment" upon the mess to the amount of ten dollars for each member; and as there was no paymaster on board, the officers had but very little ready money, and were anxious to know where all the funds paid into the treasury went to. He also found that the caterer's authority was not as much respected as he had a right to claim, for during the very first meal Frank ate in the mess, a dispute arose which threatened for a time to end in the whole matter being carried before the captain.
