May 11, 1864, was the fourth day of almost continuous combat in the Battle of Spotsylvania, Virginia. Many men were so exhausted by May 11th that they collapsed and slept in the mud while enemy fire passed a few inches over their heads. The battle lasted from May 8-21, 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 at Spotsylvania during the entire Spotsylvania Campaign (May 8-21,1864). The 36th Infantry fought at Spotsylvania May 18-21,1864.
