On August 28, 1862, fewer than 100 men became casualties at the Battle of Thoroughfare Gap, a narrow notch in the Bull Run Mountains about 35 miles west of Washington. What happened there decided the Second Battle of Bull Run the next day, and what happened at Second Bull Run helped open the road for Lee's first invasion of the North. Brigadier General James Ricketts of the Union army made a defensive choice at the Gap that should have been made by his cavalry instead. The mistake cost the Union almost everything that month.
