"Then, when you run out of ammunition and the enemy continues to advance - to the bayonet, when they break your knife - to your hands, when they break both of your hands - to your teeth, when you get the last tooth knocked out, as long as you move, as long you are there - attack! When they mortally wound you, see to it that you fall in their way, so they have to go around you, jump over you or move you - bother them even in death!" speech of lieutenant Tasic before battle of Cer 1914.
