It was a feverish time among the pilots. Some were for the Union--others would go with the Confederacy. Horace Bixby stood for the North, and in time was chief of the Union river-service. A pilot named Montgomery (Clemens had once steered for him) went with the South and by and by commanded the Confederate Mississippi fleet. In the beginning a good many were not clear as to their opinions. Living both North and South, as they did, they divided their sympathies. Samuel Clemens was thoughtful, and far from bloodthirsty. A pilothouse, so fine and showy in times of peace, seemed a poor place to be in when fighting was going on. He would consider the matter. "I am not anxious to get up into a glass perch and be shot at by either side," he said. "I'll go home and reflect." He went up the river as a passenger on a steamer named the "Uncle Sam." Zeb Leavenworth, formerly of the "John J. Roe," was one of the pilots, and Clemens usually stood the watch with him. At Memphis they barely escaped the blockade. At Cairo they saw soldiers drilling--troops later commanded by Grant. The "Uncle Sam" came steaming up to St. Louis, glad to have slipped through safely. They were not quite through, however. Abreast of Jefferson Barracks they heard the boom of a cannon, and a great ring of smoke drifted in their direction. They did not recognize it as a thunderous "Halt!" and kept on. Less than a minute later, a shell exploded directly in front of the pilot-house, breaking a lot of glass and damaging the decoration. Zeb Leavenworth tumbled into a corner. "Gee-mighty, Sam!" he said. "What do they mean by that?" Clemens stepped from the visitors' bench to the wheel and brought the boat around. "I guess--they want us--to wait a minute--Zeb," he said. They were examined and passed. It was the last steamboat to make the trip through from New Orleans to St. Louis. Mark Twain's pilot days were over. He would have grieved had he known this fact. "I loved the profession far better than any I have followed since," he long afterward declared, "and I took a measureless pride in it." At the time, like many others, he expected the war to be brief, and his life to be only temporarily interrupted. Within a year, certainly, he would be back in the pilot-house. Meantime the war must be settled; he would go up to Hannibal to see about it. XVIII. THE SOLDIER When he reached Hannibal, Samuel Clemens found a very mixed condition of affairs. The country was in an uproar of war preparation; in a border State there was a confusion of sympathies, with much ignorance as to what it was all about. Any number of young men were eager to enlist for a brief camping-out expedition, and small private companies were formed, composed about half-and-half of Union and Confederate men, as it turned out later.
