William Pitt Riddell Confederate Records found on Footnote!

I was thrilled when I discovered that Footnote.com had digitized the Confederate records of William Pitt Riddell. He was the chief surgeon at the hospital at Houston Texas during the Civil War. He was captured and had to promise not to associate with the Confederates in New Orleans where he taught Chemistry at Louisiana State University. His brother John Leonard Riddell was the postmaster and Chemistry professor at Tulane University. William and John Leonard had another brother who was also a doctor: George Riddell who resided in Chippewa Falls, Wisconsin. George is my direct ancestral line.
