Then Slim relates at one critical point in the retreat in a jungle clearing he came across a unit which was in a bad way. “I took one look at them and thought “My God, they’re worse than I supposed.” then I saw why. I walked round the corner of that clearing and I saw officers making themselves a bivouac. They were just as exhausted as their men, but that isn’t my point. Officers are there to lead. I tell you, therefore, as officers, that you will neither eat, nor drink, nor sleep, nor smoke, nor even sit down until you have personally seen that your men have done those things. If you will do this for them, they will follow you to the end of the world. And, if you do not, I will break you.”
This is why he is one of the best.
