Once More Into The Breach

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.
"Henry V" (5.3.44-51)
