Early in March, 1862, a National army commanded by Gen. John Pope moved down the west bank of the Mississippi against the position at New Madrid. A reconnoissance in force demonstrated that the place could be carried by storm, but could not be held, since the Confederate gunboats were able (the river being then at high water) to enfilade both the works and the approaches. General Pope went into camp two miles from the river, and sent to Cairo for siege-guns, meanwhile sending three regiments and a battery, under Gen. J. B. Plummer, around to a point below New Madrid, where in the night they sunk trenches for the field-guns and placed sharp-shooters at the edge of the bank, and next day opened a troublesome fire on the passing gunboats and transports. Four guns were forwarded promptly from Cairo, being taken across the Mississippi and over a long stretch of swampy ground where a road had been hastily prepared for the purpose, and arriving at dusk on the 12th. That night Pope's forces crowded back the Confederate pickets, dug trenches, and placed the guns in position. The enemy's first intimation of what was going on was obtained from a bombardment that opened at daylight. The firing was kept up through the day, and some damage was inflicted on both sides; but the next night, in the midst of a heavy storm, New Madrid was evacuated. The National forces took possession, and immediately changed the positions of the guns so as to command the river. On the 16th five Confederate gunboats attacked these batteries; but after one boat had been sunk and some of the others damaged, they drew off. On the 16th and 17th the National fleet of gunboats, under Commodore Andrew H. Foote, engaged the batteries on Island No. 10, and a hundred heavy guns were in action at once. The ramparts in some places had been weakened by the wash of the river, and the great balls went right through them. But the artillerymen stood to their work manfully, many of them in water ankle deep; and though enormous shells exploded within the forts, and one gun burst and another was dismounted, the works were not reduced. A gun that burst in the fleet killed or wounded fourteen men. The attack was renewed from day to day, and one of the batteries was cleared of troops, but with no decisive effect. At the suggestion of Gen. Schuyler Hamilton, a canal was cut across the peninsula formed by the bend of the river above New Madrid. This task was confided to a regiment of engineers commanded by Col. Josiah W. Bissell, and was completed in nineteen days. The course was somewhat tortuous, and the whole length of the canal was twelve miles. Half of the distance lay through a thick forest standing in deep water; but by an ingenious contrivance the trunks of the trees were sawed off four and a half feet below the surface, and a channel fifty feet wide and four feet deep was secured, through which transports could be passed.
