Robert E. Lee
It is well that war is so terrible - otherwise we would grow too fond of it.
You cannot be a true man until you learn to obey.
To be a good soldier, you must love the army. To be a good commander, you must be willing to order the death of the thing you love.
True patriotism sometimes requires of men to act exactly contrary, at one period, to that which it does at another, and the motive which impels themthe desire to do rightis precisely the same.
