I'm sorry that I don't know anything about the strength of the 71st Ind before Richmond, Ky, but I do know a lot about Korff in Germany, his military and political associations there, his service with the 10th Ohio, and some of his life after the war. . Buell sought to court martial him. He was an associate of Marx & Engels in Koln in 1848. He died in Chicago. E mail me for more info. If you have data on him at Richmond I would like to Know.
