The regiment in which Paul enlisted was ordered to Cairo, in Illinois, where it joined several others. When the men were enlisted, they expected to march at once upon the Rebels, but week after week passed by, spring became summer, and summer lengthened into autumn, and there was no movement of the troops. The ardor of their patriotism died out. It was a monotonous life, waking early in the morning to answer roll-call, to eat breakfast of salt pork and hard-tack, drilling by squads, by companies, by battalion, marching and countermarching, going through the same manoeuvres every day, shouldering, ordering, and presenting arms, making believe load and fire, standing on guard, putting out their lights at nine o'clock at night,--doing all this, week after week, with the Rebels at Columbus, only twenty miles down the river. It was very irksome. Sometimes Paul's heart went back to New Hope, as the dear old times came crowding upon him; but he had learned to be patient. He knew that it was necessary for soldiers to become disciplined. He had enlisted for the war, he gave his whole attention to doing his duty, and received his reward by being made a sergeant. He kept his gun clean, his equipments in good order, and he was always in his place. So prompt was he, that his commander nicknamed him Sergeant Ready. He was as ready to play a game of football, or to run a race, as he was to appear in the ranks at drill. When off duty, instead of idling away his time, he was studying the tactics, learning not only his duty as a sergeant, but what it would be if he were a lieutenant or a captain. The camp of his regiment was near the town, on the bank of the Mississippi, where he saw the great steamboats pass down the Mississippi from St. Louis, and down the Ohio from Louisville and Cincinnati, with thousands of troops on board, with the flags and banners streaming, the bands playing, and the soldiers cheering. It was pleasant to stand upon the levee, and behold the stirring scenes,--the gunboats commanded by the brave and good Admiral Foote, the great eleven-inch guns peeping from the portholes,--but Paul longed for active life. He rejoiced when he heard that his regiment was ordered to leave the Ohio River and go down toward Columbus on a reconnoitring expedition. The soldiers were so happy that they threw up their caps and gave a loud hurrah. With their haversacks full of hard-tack and cold boiled beef, carrying their tin cups and plates, their cartridge-boxes full of cartridges, they embarked on one of the great steamboats, and floated down the river. They were exhilarated with the thought that they were to have new and untried experiences,--that perhaps there would be a battle. They paced the deck of the steamboat nervously, and looked carefully into the woods along the river-bank to see if there were any Rebel scouts lurking behind the trees.
