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.

William Shakespeare (1564-1616): King Henry V. Act iii. Sc. 1.
