The First Battle of Bull Run

150 year ago this week.  Largest battle up to that point in the Civil War.

Bull Run Battle was lost by us not from want of combination, strategy or tactics, but because our army was green as grass. ... [It] was one of the best planned battles of the war, but one of the worst-fought. Both armies were fairly defeated, and whichever stood fast the other would have run.--General William Tecumseh Sherman
