The first battle of Bull Run was fought July 21, 1861. This battle both were unprepared, both sides had about 18,000 poorly trained soldiers and the Confederate ended up with the victory of a disorganized retreat by the Union. In the movie The Blue and The Gray there was a scene when both sides marched into battle and many were killed and they blew up a house by where they were fighting and Jonas went back after the battle and saw countless bodies dead.
