Arthur Conan Doyle,
Sir Nigel — Chapter VI
(1906)
“ It is right that you should think so, Nigel. At your age a man should have a hot head and a high heart. I also had both and fought for my lady's glove or for my vow or for the love of fighting. But as one grows older and commands men one has other things to think of. One thinks less of one's own honor and more of the safety of the army. It is not your own spear, your own sword, your own arm, which will turn the tide of fight; but a cool head may save a stricken field. ”
