(1814–62) Union army officer, born in New York City. His division first saw combat during the 1862 Peninsular campaign, helping to prevent disaster at the battle of Williamsburg. At Second Bull Run (1862) he led the most successful Union attack of the battle but was killed during a subsequent encounter while retreating. He was considered one of the best division commanders in the Union army. Kearny had previously served on the staff of Gen. Winfield Scott, and during the Mexican War (1846–48) he lost an arm in the unsuccessful attack on Mexico City (1847).
