Confederate military units raised in Woodstock included Company F (the Muhlenberg Rifles) of the 10th Virginia Infantry (of whom 71% had German surnames) as well as Company C of the 33rd Virginia Infantry, part of the Stonewall Brigade led by Thomas "Stonewall" Jackson. While the area had an active Confederate population, it also was home to many reluctant secessionists, Unionists and families religiously opposed to slavery and war (Mennonites, German Dunkards.) In addition, traditional enmity between the slavery-based plantation society in eastern Virginia and the small farm populations over the rugged Blue Ridge and Allegheny mountains, where slavery was not as predominant an economic institution, meant that allegiances in the Shenandoah Valley and western Virginia were often divided. Many of German descent in the Shenandoah Valley were generally or religiously opposed to slavery, even as others with German ethnicity served in the Confederate Army.
