CHAPTER 19: On Good Faith Between Enemies
"Good faith due to enemies of every description — Due even to pirates, and others of the same kind, in all treaties with them — A promise given to them, binding, when not extorted by fear — Oaths to be inviolably observed — The law of nations does not allow fear to be alleged as an exception to the above rules — Good faith to be observed even to a treacherous enemy — This obligation ceases, where one of the parties violates his engagements — Or refuses a just compensation — Even where the obligation arose from a different contract — From loss occasioned — Or from a penalty — Application of these principles to war."
