1860s, Letter to James C. Conkling (1863)
Context: You dislike the emancipation proclamation; and, perhaps, would have it retracted. You say it is unconstitutional — I think differently. I think the constitution invests its commander-in-chief, with the law of war, in time of war. The most that can be said, if so much, is, that slaves are property. Is there — has there ever been — any question that by the law of war, property, both of enemies and friends, may be taken when needed? And is it not needed whenever taking it, helps us, or hurts the enemy? Armies, the world over, destroy enemies' property when they can not use it; and even destroy their own to keep it from the enemy. Civilized belligerents do all in their power to help themselves, or hurt the enemy, except a few things regarded as barbarous or cruel. Among the exceptions are the massacre of vanquished foes, and non-combatants, male and female.
