Ken I have an account of an officer who served in that regiment. He was very unflattering about Ritchie as I recall and seems to have had the same opinion of Scharte which he called Col. Shortey -

Col. William A. Phillips, appointed Samuel Houston Benge, Sr. as a Captain in the 2nd IHG. When Benge reported Phillips introduced Benge to the 2nd IHG Colonel. The colonel invited Captain Benge to his quarters, and after passing around the canteen freely the Colonel became officious and desired to show his authority, calling out the officers of his regiment to drill. The abuse and curusing they received from their drunken superior caused Captain Benge to leave his commission at Headquarters with Col. Phillips. Benge went directly to Co. A, third Indian Home Guard Regiment, and enlisted as a private soldier. After one week's service he was pormoted to th rank of First Lieutenant of his regiment and served in that capacity for three years.

I have a picture of Benge in a officers uniform and full bio.
