William Strong, Planters' Bank v. Union Bank — Opinion of the Court
“ And it is by no means to be admitted that a conquering power may compel private debtors to pay their debts to itself, and that such payments extinguish the claims of the original creditor. It does indeed appear to be a principle of international law that a conquering state, after the conquest has subsided into government, may exact payment from the state debtors of the conquered power, and that payments to the conqueror discharge the debt, so that when the former government returns the debtor is not compellable to pay again. ”
