From May 31-June 12, 1864, more than 160,000 men clashed at Cold Harbor, Virginia, during the Wilderness Campaign. The 2nd, 5th, 6th, 7th and 36th Wisconsin Infantry regiments took part. On June 1, the 5th Wisconsin Infantry arrived after a long march, barefoot and exhausted. Nevertheless, they charged enemy lines and captured a number of prisoners. By the afternoon, the 36th Wisconsin Infantry lost 140 of the 142 men who tried to take an enemy position.
