Capt. David C. Van Buskirk served with the 27th Indiana from the start of the war until April 1864 - prolonging a national fitness scandal year after year. Every minute he remained in uniform, he disgraced it - by today's standards.

What was his two-mile run time? How many sit-ups could he do in a minute?
Those were the dark ages for fitness standards.
