Plummer enlisted on April 23, 1861, in Company C of the 6th Wisconsin Infantry, was promoted to 1st lieutenant just four days later, promoted to captain of Company G on October 23, and then major on April 12, 1864. He was killed in the Battle of the Wilderness on May 5, 1864. The 6th Wisconsin saw action in the Eastern Theater throughout the war and was part of the famous Iron Brigade. They fought at Second Bull Run, South Mountain, Antietam, Chancellorsville, Gettysburg, the Wilderness, Spotsylvania Court House, Cold Harbor, Petersburg, Weldon Railroad, and Five Forks. At Antietam where this pistol is identified as capture, the 6th Wisconsin Infantry was heavily engaged and led a charge through the woods and into a cornfield. After the charge, 150 of the 6th's 280 men had been killed or wounded, and the Iron Brigade suffered 343 of its 800 officers and enlisted men wounded or killed in the battle. May 5, 1864, was the opening of the Battle of the Wilderness. The 6th Wisconsin Infantry Regiment suffered nearly 50 casualties in a matter of minutes when the Iron Brigade's exposed flank was attacked by the Confederates led by Brigadier General George P. Doles during the fighting at Saunders Field.
