The Culper Code Book was used by the Culper spy ring to send coded messages to George Washington's headquarters during the Revolutionary War.

Under the orders of General George Washington, Major Benjamin Tallmadge organized the Culper Spy Ring in 1778 to gather information on British troop movements, fortifications, and military plans in the New York area.

Informants used fake names and a numerical code book consisting of seven hundred and sixty-three numbers representing words, names, and places to communicate their information. Developed by Tallamadge, the Culper Code Book was essential in protecting the vital communications and identities of this important intelligence gathering group.
