was stopped on August 6. As Herkimer marched through the forest at the head of a force of 800, they were ambushed by the Loyalists, who brought down heavy fire from their positions in the forest. The Americans stood their ground, and after six hours of fighting, the battle ended inconclusively, though the Americans losses, at about 250 dead, were much greater than the Loyalist losses. The Canadian historian Desmond Morton described Brant's Iroquois warriors as having "annihilated a small American army". Though Brant stopped Herkimer, the heavy losses taken by the Loyalist Iroquois at Oriskany led the battle to be considered a disaster by the Six Nations, for whom the loss of any life was unacceptable, making the 60 Iroquois dead at Oriskany a catastrophe by Iroquois standards. St. Leger was eventually forced to lift the siege when another American force approached, and Brant traveled to Burgoyne's main army to inform him. The Oneida, who had sided with the Americans together with the Tryon County militia sacked Canajoharie, taking particular care to destroy Molly Brant's house. Burgoyne restricted participation by native warriors, so Brant departed for Fort Niagara, where his family joined him and he spent the winter planning the next year's campaign. His wife Susanna likely died at Fort Niagara that winter. (Burgoyne's campaign ended with his surrender to the Patriots after the Battles of Saratoga.) Helping Brant's career was the influence of his sister Molly, whom Daniel Claus had stated: "one word from her [Molly Brant] is more taken notice of by the Five Nations than a thousand from a white man without exception". The British Army officers found Molly Brant to be bad-tempered and demanding, as she expected to be well rewarded for her loyalty to the Crown, but as she possessed much influence, it was felt to be worth keeping her happy. In April 1778, Brant returned to Onoquaga. He became one of the most active partisan leaders in the frontier war. He and his Volunteers raided rebel settlements throughout the Mohawk Valley, stealing their cattle, burning their houses, and killing many. The British historian Michael Johnson called Brant the "scourge of the American settlements of New York and Pennsylvania", being one of the most feared Loyalist irregular commanders in the war. Morton wrote the fighting on the New York frontier was not so much between Americans and the British as "a cruel civil war
