 At first, Woodhull had to return to Setauket to pass messages to Caleb Brewster, a Continental Army officer who spent most of his time operating whaleboats on Long Island Sound for secret military purposes, to take to Tallmadge or to receive messages from Tallmdadge via Brewster.By December 1778, Tallmadge set up couriers, at first Jonas Hawkins, then in the early summer mainly Austin Roe, who would take messages the between New York and Setauket to pass them to Brewster.Hawkins's task was to get the letters to Brewster who would pick up messages at Setauket and take them across the Sound to Tallmadge at Fairfield, Connecticut.
