The Young Earl of Essex's Victory over the Emperor of Germany
The Young Earl of Essex’s Victory Over the Emperor of Germany is Child Ballad 288.
The earl takes to sea—despite, in some variants, the pleas of his love and her reminder of the fate of Benbow -- and meets up with ships of the emperor of Germany. They hail each other, and the earl's proud greeting causes the emperor's son to ask for ships to go against him. They fight, and the emperor's son is defeated and captured. The emperor tries to ransome him, but the earl insists on bringing him prisoner before the queen.
