On July 18, 1862, Newburgh was the first town north of the Mason-Dixon line to be captured by the Confederate forces during the American Civil War. Colonel Adam R. Johnson, with a partisan band, crossed the Ohio River and confiscated supplies and ammunition without a shot being fired. The Confederates would have been unable to shell the city (as promised) had Newburgh put up a fight. The Confederates' 'cannons' were an assemblage of stove pipe, a charred log, and wagon wheels.
Newburgh grew steadily during the second half of the 20th Century with the increase of industry in the Evansville Metropolitan Area. Major area employers include Alcoa, Toyota Motors, Mead Johnson Pharmaceuticals, Atlas Van Lines, the University of Evansville, and the University of Southern Indiana. Today, Newburgh boasts a lively historic district, a high school (Castle) that competes in statewide competitions in both athletics and academics.
