Revolutionary War officer and New York City politician, Nicholas Fish (1758-1833), was born into a wealthy New York City family. He studied law at age 17 before becoming a soldier in the Revolution. As a law clerk, Fish formed a lifelong friendship with Alexander Hamilton, and was later executor of his will. In 1776, Fish enlisted as a second lieutenant in Colonel John Lasher's First Battalion of New York Independents, beginning his military career that would last the war. In August 1776, he became General John Morin Scott's brigade major, and saw action at Long Island. In 1778 Fish was appointed division inspector under Steuben and commanded an infantry unit at the battle of Monmouth. He joined John Sullivan's expedition against the Indians in 1779, fought with Lafayette from 1780 to 1781, and served as Colonel Hamilton's second in command at Yorktown.
After the war, Fish was appointed supervisor of the revenue for New York (1793). He became deeply involved in New York City and state politics, first as an alderman (1806-1817), then as an unsuccessful Federalist candidate for lieutenant governor in 1810. He also served as president of the New York chapter of the Society of the Cincinnati, as chairman of the Board of Trustees of Columbia College, and in many other charitable societies. Fish married Elizabeth Stuyvesant in 1803. He died in New York City in 1833.
