One of the absolute rules I learned in the war was, don't know anything you don't need to know, because if you ever get caught they will get it out of you.
When envoys are sent with compliments in their mouths, it is a sign that the enemy wishes for a truce. If the enemy's troops march up angrily and remain facing ours for a long time without either joining battle or removing demands, the situation is one that requires great vigilance and circumspection. To begin by bluster, but afterward to take fright at the enemy's numbers, shows a supreme lack of intelligence.
Nothing is more dangerous in wartime than to live in the temperamental atmosphere of a Gallup Poll, always feeling ones pulse and taking ones temperature. I see that a speaker at the week-end said that this was a time when leaders should keep their ears to the ground. All I can say is that the British nation will find it very hard to look up to leaders who are detected in that somewhat ungainly posture.
Never lead your soldiers to battle if you have not first confirmed their spirit and known them to be without fear and ordered; and never test them except when you see that they hope to win.
O shame to men! Devil with devil damned Firm concord holds, men only disagree Of creatures rational, though under hope Of heavenly grace: and God proclaiming peace, Yet live in hatred, enmity, and strife Among themselves, and levy cruel wars, Wasting the earth, each other to destroy: As if (which might induce us to accord) Man had not hellish foes enough besides, That day and night for his destruction wait.
