Arnold arrived in Schuyler's camp at Fort Edward, New York on July 24. On August 13, Schuyler sent Arnold with 900 soldiers to help soldiers at Fort Stanwix. There, Arnold used a trick win. Arnold had a Native American messenger go into the camp of British Brigadier General Barry St. Leger. The messenger said that Arnold's army was much larger and closer than it truly was. St. Leger's Native American soldiers abandoned him, so St. Leger and the rest of his soldiers had to leave too.
