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.

Henry V (1599) act 3, sc. 1, l. 1
