Although it is not true today, I do believe that during the Civil War, wounded men had to pay for the their train rides to from from hospitals. This was true if you rode on civilian trains or military trains. If you were expected to recover at home, or be on medical leave, you paid those transportation costs as well. One Michigan captain was wounded at Gettysburg and not able to provide the paper work explaining how he lost such a large number of weapons, equipment and uniforms. Most of his company was killed and capture. The resulting cost ruined him and his family was still typing to get the Army to clear this up decades after his death.
I went to a military school at an Army base which cost the government $40,000. For some reason my graduation certificate was lost in the mail and the proper people never got it I had thus spent the money without cause and I receive a letter telling me the military had issued a warrant for my arrest. I had a copy of my graduation certificate but they needed the original and the original was lost. They were nice enough to give me 24 hours to come up with the money. I sure had to pull in a lot of favors to clear this up. I still had to deal with the fact that a warrant for my arrest had been issued for years. I can verify that special agents who pull you secret clearance have no sense of humor what -so-ever. Try explaining this type of thing on a job application, the why were you arrested box is not nearly big enough to explain it.
