After secession, some North Carolinians refused to support the Confederacy. Some of the yeoman farmers in the state's mountains and western Piedmont region remained neutral during the Civil War, while some covertly supported the Union cause during the conflict. Approximately 2,000 North Carolinians from western North Carolina enlisted in the Union Army and fought for the North in the war. Two additional Union Army regiments were raised in the coastal areas of the state, which were occupied by Union forces in 1862 and 1863. Numerous slaves escaped to Union lines, where they became essentially free.
