His 1st wife died while he was in MO or there abouts, and he took the train home for for a week or so (I'd have to look that up again to be exact). He resigned his comish on Sept. 2nd (as you had) while he was in New Orleans, Louisiana. He had a funny entrie in his diary (or could have been a letter) where he watch a military review down their where Grant was so drunk he fell off his horse! I've heard various things about William and drinking from him being strictly against it, to where he drank a lot after the civil war."
