Biography of Benjamin Tallmadge, Leader of the Culper Spy Ring
Benjamin Tallmadge was an officer in the Continental Army during the American Revolutionary War and was also the head of the Culper Spy Ring. Tallmadge was from New York and was offered a position in the Connecticut militia in June 1776. With that unit, he fought in the Battle of Long Island. Later that year, he was given a commission in the 2nd Regiment of Light Dragoons. In 1777, He was at the Battle of Brandywine and the Battle of Germantown. In 1778, General George Washington put Tallmadge in command of military intelligence and he was responsible for gathering information about British operations in and around New York City. Tallmadge set up a network — the Culper Spy Ring — which included Abraham Woodhull and Robert Townsend. In 1780, Tallmadge and the Culper Ring played a key role in revealing that Benedict Arnold was working with the British, which is known as Arnold’s Treason. A month later, on November 21, Tallmadge led an expedition that captured and burned Manor St. George and then burned 300 tons of hay the British had gathered for the winter. In 1781, Tallmadge moved to Washington’s headquarters and served there until the end of the war. After the war, he was a founding member of the Society of Cincinnati. He was active in politics and was elected to represent Connecticut in the United States House of Representatives.
After John Andre was captured, Tallmadge interrogated him, which helped uncover the Treason of Benedict Arnold. Image Source: New York Public Library Digital Collections.
