"To carry the spirit of peace into war is a weak and cruel policy. When an extreme case calls for that remedy which is in its own nature most violent, and which, in such cases, is a remedy only because it is violent, it is idle to think of mitigating and diluting. Languid war can do nothing which negotiation or submission will do better: and to act on any other principle is, not to save blood and money, but to squander them."
