"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 warre blows in our eares,
Then imitate the action of the tyger:
Stiffen the sinews, conjure up the blood,
Disguise fair nature with hard-featured rage,
Then lend the eye a terrible aspect;
Now set the teeth, and stretch the nostrill wide,
Hold hard the breath, and bend up every
Spirit to his full height! On, on, you noble English!"

(A note tells us that the word 'breach' in the first line refers to a gap in the wall)
