Herkimer, Nicholas (1728–1777), an American Revolutionary War army officer. Herkimer was born in German Flats (now Herkimer), New York. During the Saratoga campaign he collected about 800 county militia to relieve Fort Stanwix (at what is now Rome, New York), which was being besieged by forces under British General Barry St. Leger. The patriots were ambushed and defeated in the Battle of Oriskany, August 6, 1777. Herkimer, a brigadier general, directed his troops though badly wounded. He died a few days later. St. Leger lost so many men that he retreated when he learned that Benedict Arnold was approaching with American reinforcements.
