Unionism—opposition to the Confederacy—was widespread, especially in the mountain regions of Appalachia and the Ozarks. Unionists, led by Parson Brownlow and Senator Andrew Johnson, took control of eastern Tennessee in 1863. Unionists also attempted control over western Virginia but never effectively held more than half the counties that formed the new state of West Virginia. Union forces captured parts of coastal North Carolina, and at first were welcomed by local unionists. That changed as the occupiers became perceived as oppressive, callous, radical and favorable to the Freedmen. Occupiers engaged in pillaging, freeing of slaves, and eviction of those refusing to take or reneging on the loyalty oaths, as ex-Unionists began to support the Confederate cause.
