How legal.
"You stupid Greeks, I have known your cunning ways for long enough. The late Sultan was a lenient and conscientious friend to you. The present Sultan Mehmed is not of the same mind. If Constantinople eludes his bold and imperious grasp, it will only be because Allah continues to overlook your devious and wicked schemes. You are fools to think that you can frighten us with your fantasies and that when the ink on our recent treaty of peace is barely dry. We are not children without strength or sense. If you think that you can start go ahead. If you want to bring the Hungarians across the Danube, let them come. If you want to recover places that you lost long since, try it. But know this: you will make no headway in any of these things. All that you will do is lose what little you still have."
-Halilpaşa, vezir of Mehmed II, to the envoys of Konstantinos XI, 1451
"For ourselves, we shall not trouble you with specious pretenses - either of how we have a right to our empire because we overthrew the Mede, or are now attacking you because of wrongs that you have done us - and make a long speech which would not be believed; and in return we hope that you, instead of thinking to influence us by saying that you did not join the Lakedaimonians, although their colonists, or that you have done us no wrong, will aim at what is feasible, holding in view the real sentiments of us both; since you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must."
-Athenians to the Melians, demanding their surrender, 416 BC
"I'm as dead a man as Julius Caesar."
-Brig. Gen. Stephen Weed, one of the Federal commanding officers on Little Round Top, after being shot by a rebel sniper, July 2, 1863
