Once more unto the breach, dear friends, once more,
Or close the wall up with our English dead!
In peace there’s nothing so becomes a man
As modest stillness and humility;
But when the blast of war blows in our ears,
Then imitate the action of the tiger:
Stiffen the sinews, summon up the blood,
Disguise fair nature with hard-favoured rage;
Then lend the eye a terrible aspect.
– William Shakespeare
Henry V, Act 3, Scene 1.
