The Culper Spy Ring: How it Helped the American Revolution

You may have not known that there was a spy ring, let alone spies, during the American Revolution. Unlike other aspects of the American Revolution, women could help spy on the British. It was actually pretty easy for the women to spy because no one would have ever expected that they were spying on the British. The Culper Spy Ring was a very important thing for the Patriots during the Revolution, but not many people know about it. 

The Culper Spy Ring was an American spy network during the American Revolution that provided George Washington with important information about British troops. The Culper Spy Ring was created in November of 1778, when George Washington appointed Major Benjamin Tallmadge as director of military intelligence, and was in charge of creating a spy ring in New York. In the 5 years when the Culper Spy Ring operated, no spy was ever unmasked. Tallmadge’s informants consisted of friends he made at school on Long Island. That included Austin Roe, Caleb Brewster, Abraham Woodhull, and Anna Strong. Robert Townsend was also a significant informant. Robert Townsend posted as a Loyalist shop owner and merchant while working as a society reporter for an American newspaper.

The Culper Spy Ring — Spies of the American Revolution 

Nathan Hale was a captain of The Continental Army during the battle of Long Island when he disguised himself as a loyalist schoolmaster and went into British territory on September 12. He gathered information about the British before he was captured on the evening of September 21. He was executed as a spy on September 22, 1776 with his reported last words, “I only regret that I have but one life to give for my country” (American Spies of the Revolution, Mount Vernon). He is one of the people that inspired the Culper Spy Ring to be formed.

Benjamin Tallmadge founded the spy ring in 1778, in New York. He recruited friends to work as his informants. Tallmadge served as the main handler of the Culper Spy Ring until the war ended.

Austin Roe was a tavern owner and was closely tied to the other members of the Culper Spy Ring. Roe served as the courier, transporting materials from Robert Townsend’s shop in New York all the way to Setauket, Long Island. Roe’s position was very dangerous, traveling for more than fifty miles with the possibility of getting caught.

Robert Townsend was a Patriot who publicly presented himself as a Loyalist, even writing for a Loyalist newspaper to gain trust. Because of that, Townsend was trusted with sensitive information, even if it was from British military officers. Townsend relayed the information to Austin Roe to transport materials.

Abraham Woodhull was a farmer and was essentially the leader of the Culper Spy Ring. He decided what information was transmitted throughout the group, and eventually to George Washington. To evade British detection Woodhull would operate under the code name “Culper Senior”(The Culper Gang, University of Michigan). 

Anna Strong used her farmstead on Long Island to help transfer information to the other members of the Culper Spy Ring. She would arrange clothes on a clothesline as a signal to Caleb Brewster, a fellow Culper spy, regarding the location of the hidden documents.

Caleb Brewster’s role in the Culper Spy Ring was to transport information across Long Island on a whale boat. After that Brewster would sail to Connecticut to deliver the information to Benjamin Tallmadge.

How they pulled it off

First, Robert Townsend would gather information. He usually got information through British soldiers who didn’t think that he was a spy because of his job working at an American Loyalist newspaper. After Townsend gathered information from British soldiers, Austin Roe would go to his store and get the letter. Then Roe would ride for more than fifty miles to deliver the information to Abraham Woodhull’s house. 

After Roe dropped off the letter, Woodhull would look across the bay to see where Anna Strong had placed her petticoat on her clothesline. When Strong placed her black petticoat on her clothesline, that would let Woodhull know that Caleb Brewster had arrived in the whaleboat to take across the bay. The number of handkerchiefs that Strong had put on the clothesline would tell Woodhull where Brewster was hiding. When it was dark outside, Woodhull would sneak to where Brewster was hiding and give him the message. Brewster would finally row back across Devil’s Belt to Fairfield, Connecticut and give the letter to Benjamin Tallmadge, who was waiting on his horse on the other side.

To pass letters, the informants used fake names and a numerical code book. The code book was called “the Culper Code Book”. The code book consisted of seven hundred and sixty-three numbers representing words, names, and places. The Culper Code Book was an essential part of protecting every aspect of the Culper Spy Ring. If they didn’t use the numerical codes, the British could have figured out what they were doing.
