USA HISTORY

Detailed explanation-1: -After two days of marching slowly in the sweltering heat, the Union army was allowed to rest in Centreville.

Detailed explanation-2: -Despite their victory, Confederate troops were far too disorganized to press their advantage and pursue the retreating Yankees, who reached Washington by July 22. The First Battle of Bull Run (called First Manassas in the South) cost some 3, 000 Union casualties, compared with 1, 750 for the Confederates.

Detailed explanation-3: -The Union army performed well that morning, but by early afternoon the Confederates had brought in reinforcements, forcing an intense battle over a space known as Henry Hill. When Union generals finally called retreat around 4:00 p.m., the frightened soldiers fled for their lives.

Detailed explanation-4: -Stuart captured the Union artillery, and Beauregard ordered a counterattack on the exposed Union right flank. The rebels came charging down the hill, yelling furiously, and McDowell’s line was broken, forcing his troops in a hasty retreat across Bull Run.
