"my kingdom for a horse!..."See in text(Act V - Act V, Scene 4)
The arrogant and pathetic hunchbacked King Richard III refuses to withdraw, even though his horse has died.

For example, satirist John Marston (a contemporary of Shakespeare) frequently imitated the line: "A boat, a boat, a boat, a full hundred marks for a boat!"
