Charles J. Mellberg enlisted in 1861 when he was 30 years old. He was 6 feet tall, with auburn hair, gray eyes, and a light complexion. He was single, a farmer, and resided at Mendota, LaSalle County, Illinois. When he reenlisted in March of 1864, he gave his residence as Chicago. He was born at Sandskrona, Sweden.
From August 25 to November 25, 1863, Mellberg was sick in the hospital at New House of Refuge in St. Louis, Missouri, along with his battery-mates, Samuel Garst and Hiram Scutt. He was promoted to corporal on Sept. 10, 1864, but then at the end of the battery’s service, was designated “supernumerary non-commissioned officer” on account of “the Battery having been reduced to four guns” in early August, 1865. He was mustered out with the rest of the battery on Sept. 4, 1865 at Springfield, Illinois.
