At this point, the Americans were joined by an unexpected participant. General Arnold, who was "betraying great agitation and wrath" in the American camp, and may have been drinking, rode out to join the action. Gates immediately sent Major Armstrong after him with orders to return; Armstrong did not catch up with Arnold until the action was effectively over. (A letter, written by a witness to proceedings in the camp, suggests that Arnold did in fact have authorization from Gates to engage in this action.)
