A horse! A horse! My kingdom for a horse!

Catesby:
Withdraw, my lord; I'll help you to a horse.

King Richard:
Slave, I have set my life upon a cast,
And I will stand the hazard of the die.
I think there be six Richmonds in the field;
Five have I slain to-day instead of him.
A horse! A horse! My kingdom for a horse!

William Shakespeare,
"The Tragedy of King Richard The Third"
Act Five
Scene 4

1592
