Samuel Blatchford, Wood v. United States (107 U.S. 414…
“ Congress had the same right to change the claimant's rank and pay, by reducing them, that it had to change the rank and pay of Gen. Crawford, by section 1 of the act of 1875, by increasing them, the standard in both cases being the actual rank held by the officer at the time he was wounded. The offices of both were left untouched. The pay of retired officers is a matter entirely within the control of congress, and so is their rank. ”
