The 140th Regiment Pennsylvania Volunteer Infantry was a Union Army regiment in the American Civil War, serving in the Eastern Theater. Recruited in late 1862, it fought from the Battle of Chancellorsville through the war until the Army of Northern Virginia's surrender at Appomattox Court House.[1] Its losses during the war were among the highest of any Union regiment.[2]
