The two forces engage in battle, with the Lancastarians having the upper hand. Lord Stanley (Laurence Naismith), whose loyalties had been questionable for some time, betrays Richard, and allies himself with Henry. Richard sees this and charges into the thick of battle, side by side with his loyal companion Sir William Catesby (Norman Wooland) to kill Richmond and end the battle quickly. Eventually Richard spots Richmond and they briefly engage in a duel before being interrupted by Stanley's men. Richard and Catesby are able to escape the oncoming forces, but, in doing so, Richard is knocked off his horse, loses his cherished crown, and becomes separated from Catesby, who is off seeking rescue. Searching desperately for Richmond, whom he has lost sight of, Richard cries out: "A horse! A horse! My kingdom for a horse!" Catesby finds the king and offers him withdrawal, but Richard refuses to flee. Catesby is then killed by Richmond's men without Richard noticing. Richard then spots Lord Stanley, and engages him in single combat. Before a victor can emerge, the Lancastarian troops charge Richard, and fatally wound him. The wounded murderous king convulses in spasms, offering his sword to the sky, and eventually dies of his wounds. Stanley orders Richard's body to be taken away and then finds Richard's crown in a thorn bush. He then proceeds to offer it to Henry, leaving the crown of England in safe hands once again.
