The heavy loss of life during the Civil War led to the first organized system of marking graves. Wooden headboards were used at first, and changed to marble or other stone in the 1870s. This tombstone was at the grave of Corporal George B. Clark of Shakopee, Minnesota. Clark was in Company A of the First Minnesota. He was captured at Antietam, released, and wounded at Bristow Station before re-enlisting and being captured again at Petersburg. During the eight months he spent in prison, Clark nearly starved and lost his teeth due to scurvy. He never really recovered and died in 1887 at the age of 45. This original headstone was replaced in 1985 by a newer stone of the same design.
