"From the colouring on it, he sure did not run short of tobacco during his imprisonment. :D"
Actually during much of his imprisonment Davis was chained and deprived of tobacco for his pipe. Quoted from the article Kevin linked above:
"Davis was manacled for much of his two-year incarceration until U.S. Army physician Lt. Col. John Craven, ordered the chains to be removed for the prisoner’s health. It was during this time that Craven, who had been assigned the Davis case, walked into the cell and was astonished at Davis’s distressing physical condition."

"When the doctor mentioned the pipe, he also noticed that Davis was apparently suffering from acute tobacco withdrawal. Until that day, his captors had prevented him from smoking. In response, the young doctor sent an aide to find a stash of tobacco and allowed Davis to fire up his lovely meer."
