There was a constant exchange of money and goods between fellow prisoners during prison life. Foote is constantly making brief notes in his diary of borrowing or lending money to fellow comrades. “Gave Beegle a Due-Bill for $50, the amount of my indebtedness to him (Aug 23rd).”
A sort of underground economy of barter, trade and purchasing was a major part of how prisoners existed in prison conditions. As such, soldiers were constantly exchanging goods and services for items, possessions, and in some cases money. On September 5th Foote states that he lent money to four different soldiers in one day.
