On April 10 Wilson's command started for Montgomery. A negro regiment of 800 men[99] was organized at Selma and accompanied the army, subsisting on the country. Before reaching Georgia there were several such regiments. On April 12 Montgomery was surrendered by the mayor. The Confederates had burned 97,000[100] bales of cotton to prevent its falling into the hands of the enemy. The captors burned five steamboats, two rolling mills, a small-arms factory, two magazines of stores, all the rolling stock of the railways, and the nitre works, the fire spreading also to the business part of the town.[101] Here, as at Selma, horses, mules, and valuables were taken by the raiders. The force was then divided into two columns, one destined for West Point and the other for Columbus. The last fights on Alabama soil occurred near West Point on April 16, and at Girard, opposite Columbus, on the same day. At the latter place immense quantities of stores, that had been carried across the river from Alabama, were destroyed.[102] Croxton's force reached Tuscaloosa April 3, and burned the University buildings, the nitre works, a foundry, a shoe factory, and the Sipsey cotton mills. After burning these he moved eastward across the state, destroying iron works, nitre factories, depots, and cotton factories. Before he reached Georgia, Croxton had destroyed nearly all the iron works and cotton factories that had been missed by Rousseau and Wilson.[103] Destruction by the Armies For three years north Alabama was traversed by the contending armies. Each burned and destroyed from military necessity and from malice. General Wilson said that after two years of warfare the valley of the Tennessee was absolutely destitute.[104] From the spring of 1862 to the close of the war the Federals marched to and fro in the valley. There were few Confederate troops for its defence, and the Federals held each community responsible for all attacks made within its vicinity. It became the custom to destroy property as a punishment of the people. Much of the destruction was unnecessary from a military point of view.[105] Athens and smaller towns were sacked and burned, Guntersville was shelled and burned; but the worst destruction was in the country, by raiding parties of Federals and "tories," or "bushwhackers" dressed as Union soldiers. Huntsville, Florence, Decatur, Athens, Guntersville, and Courtland, all suffered depredation, robbery, murder, arson, and rapine.[106] The tories destroyed the railways, telegraph lines, and bridges, and as long as the Confederates were in north Alabama they had to guard all of these.[107] Along the Tennessee River the gunboats landed parties to ravage the country in retaliation for Confederate attacks. In the counties of Lauderdale, Franklin, Morgan, Lawrence, Limestone, Madison, and Jackson nearly all property was destroyed.[108]
