General Arnold, frustrated by the sound of fighting he was not involved in, rode off from the American headquarters to join the fray. Arnold, who some claimed was in a drunken fury, took the battle to the British position. The right side of the British line consisted of two earthen redoubts that had been erected on Freeman's Farm, and were manned by Brunswickers under Heinrich Breymann and light infantry under Lord Balcarres. Arnold first rallied troops to attack Balcarres' redoubt, without success. He then boldly rode through the gap between the two redoubts, a space guarded by a small company of Canadian irregulars. Learned's men followed, and made an assault on the open rear of Breymann's redoubt. Arnold's horse was shot out from under him, pinning him and breaking his leg. Breymann was killed in the fierce action, and his position was taken. However, night was falling, and the battle came to an end. The battle was a bloodbath for Burgoyne's troops: nearly 900 men were killed, wounded, or captured, compared to about 150 for the Americans.
