The fiercest fighting in the Battle of Spotsylvania occurred in pouring rain on May 12, 1864. For 23 hours the two sides fought hand-to-hand along lines known as the Bloody Angle. When the battle ended, the trenches were filled with bodies. Colonel Rufus Dawes of the 6th Wisconsin Infantry left of this day’s fighting. The Battle of Spotsylvania, Virginia, lasted from May 8-21, 1864, and pitted 100,000 Union troops against 52,000 Confederates. When the two weeks were over, about 11,000 Union soldiers had been killed or wounded without any clear victory for either side. The 2nd, 5th, 6th and 7th Wisconsin Infantry regiments fought during the entire Spotsylvania Campaign (May 8-21,1864); the 36th Infantry fought at Spotsylvania May 18-21,1864.
