Dating George Washington’s Receipt of a Samuel Culper Letter to Benjamin Tallmadge

Abraham Woodhull (alias Samuel Culper), a farmer and Patriot spy on British-controlled Long Island, wrote Maj. Benjamin Tallmadge (alias John Bolton) a letter from Setauket, N.Y., on August 16, 1780 that is in the Papers of George Washington at the Library of Congress. Although the editors at The Papers of George Washington do not know precisely when George Washington received that letter, we can make a reasoned guess.

A “New” Samuel Culper Letter

One of the most enjoyable aspects of documentary editing at The Washington Papers is making annotated transcriptions of relatively inscrutable manuscripts readily available, manuscripts like spy letters with incomplete decryptions. On Sept. 9, 1780, Maj. Benjamin Tallmadge (alias John Bolton) wrote Gen. George Washington from North Castle, N.Y., and forwarded two letters addressed to him that he had received from Abraham Woodhull (alias Samuel Culper), a farmer and spy on British-controlled Long Island, New York. A preliminary transcription of Tallmadge’s letter to Washington, dated September 9, can be found on Founders Online. No transcription, however, is currently available of the enclosed Woodhull letters, which are among Washington’s papers at the Library of Congress.
