Arnold led the American chase, and then led Poor's men in an attack on the Balcarres redoubt. Balcarres had set up his defenses well, and the redoubt was held, in action so fierce that Burgoyne afterwards wrote, "A more determined perseverance than they showed … is not in any officer's experience". Seeing that the advance was checked, and that Learned was preparing to attack the Breymann redoubt, Arnold moved toward that action, recklessly riding between the lines and remarkably emerging unhurt. He led the charge of Learned's men through the gap between the redoubts, which exposed the rear of Breymann's position, where Morgan's men had circled around from the far side. In furious battle, the redoubt was taken and Breymann was killed. Arnold's horse was hit in one of the final volleys, and Arnold's leg was broken by both shot and the falling horse. Major Armstrong finally caught up with Arnold to officially order him back to headquarters; he was carried back in a litter.
