'Once more into 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 blowes in our ears, then imitate the action of the tiger;
Stiffen the sinews, summon up the blood, disguise fair nature with hard-favored rage;
Then lend the eye a terrible aspect.'
-William Shakespeare
