 Brant gained additional native followers during the war and was perhaps the only Indian to be commissioned as a British captain, but he was not, as has sometimes been claimed, the head war chief of the Iroquois.Brant took part in a joint British-Indian invasion of New York in 1777, which for the British ended in a disastrous surrender at Saratoga.Afterwards, he led numerous frontier raids, both before and after the massive American invasion of 1779, which left the Iroquois lands devastated.
