William Slim quotes:

When you cannot make up your mind which of two evenly balanced courses of action you should take - choose the bolder.

Moral courage is higher and a rarer virtue than physical courage.

The dominant feeling of the battlefield is loneliness.

There is only one principle of war and that's this. Hit the other fellow, as quickly as you can, as hard as you can, where it hurts him most, when he ain't lookin'.
