There is no mistake; there has been no mistake; and there shall be no mistake.

All the business of war, and indeed all the business of life, is to endeavour to find out what you don't know by what you do; that's what I called 'guess what was at the other side of the hill'.

The whole art of war consists in getting at what is on the other side of the hill.

Nothing except a battle lost can be half so melancholy as a battle won.

Next to a battle lost, the greatest misery is a battle gained.

Next to a lost battle, nothing is so sad as a battle that has been won.
