During the American Civil War the trade with the South dwindled, as New Albany was boycotted by both sides, by Confederates because it was in a Union state and by the North because it was considered as too friendly to the South. Indianapolis overtook New Albany as Indiana's largest city in 1860 and across the river Louisville's population grew much faster, New Albany never regained its original stature. The once robust steamboat industry ended by 1870, with the last steamboat built in New Albany named, appropriately, the "Robert E. Lee".
