He was the spy who gave America the victory in the revolution battle of Yorktown.
After successfully infiltrating British intelligence, Armistead floated freely between the British and American camps. As a double agent, he relayed critical information to Lafayette and misleading intel to the enemy. Oblivious to his true intentions, the British assigned Armistead to work under the notorious turncoat, Benedict Arnold. By helping Arnold maneuver his troops through Virginia, Armistead gained significant insight into the Redcoats’ movements.
Several of Armistead’s finest acts occurred in 1781, during a critical moment in the Revolution—the Battle of Yorktown. The spy informed Lafayette and Washington about approaching British reinforcements, which allowed the generals to devise a blockade impeding enemy advancements. This success resulted in the final major victory for the colonists when Lord Cornwallis surrendered on October 17, 1781.
Though Americans celebrated freedom throughout the United States at the end of the war, James Armistead returned to life as a slave. His status as a spy meant that he did not benefit from the Act of 1783, which emancipated any slave-soldiers that fought for the Revolution.
As a result, Armistead began the process of petitioning Congress to fight for his freedom. After several years without success, Armistead received help from an old comrade in arms, the Marquis de Lafayette. Upon learning that Armistead remained enslaved, Lafayette wrote a letter to Congress on his behalf. Armistead received his manumission in 1787.
Living off his annual pension fee, Armistead moved to his own 40-acre farm in Virginia, where he married, raised a family, and lived out the rest of his life as a freeman. Armistead added Lafayette to his name as a token of gratitude and a testament to the bond the former slave and French general shared.
The two crossed paths again during Lafayette’s grand tour of the United States in 1824, where the general picked James out of a crowd and cordially embraced him. James Armistead Lafayette died in 1832.
Biography:
The only direct reference to 355 in any of the Culper Ring's missives (1778–1780)[3] appears in a letter from Abraham Woodhull ("Samuel Culper Sr.") to General George Washington,[4] where Woodhull describes her as "one who hath been ever serviceable to this correspondence."[5]
The true identity of 355 remains unknown, but some facts about her seem clear. She worked with the American Patriots during the Revolutionary War as a spy, and was likely recruited by Woodhull into the spy ring.[1] The way the code is constructed indicates that she may have had "some degree of social prominence."[2] She was likely living in New York City at the time,[6] and at some point had contact with Major John André and Benedict Arnold.[7][8] One person who has been named as the possible identity of Agent 355 was Anna Strong, Woodhull's neighbor.[6] Strong allegedly helped the Culper Ring by signaling to its members the location of Caleb Brewster, who raided British shipments in his whaleboat around Long Island Sound after he was given a secure location by Strong.[3]
