 She hung a black petticoat on her clothesline at Strong Point in Setauket, which was easily visible by Brewster from a boat in the Sound and by Woodhull from his nearby farm after he began to operate from Setauket.She would add a number of handkerchiefs for one of six coves where Brewster would bring his boat and Woodhull would meet him.Historian Richard Welch writes that the tradition of the clothesline signal is unverifiable but it is known that the British had a woman at Setauket who fits Anna's profile under suspicion for disloyal activities.
