Concept note-1: -On July 21, 1861, Union and Confederate armies clashed near Manassas Junction, Virginia. The engagement began when about 35, 000 Union troops marched from the federal capital in Washington, D.C. to strike a Confederate force of 20, 000 along a small river known as Bull Run.
Concept note-2: -On the Confederate side, Gen. Robert E. Lee’s Army of Northern Virginia was organized into two “wings” or “commands” totaling about 55, 000 men: Maj. Gen.
Concept note-3: -Despite heavy Confederate casualties (9, 000), the Battle of Second Bull Run (known as Second Manassas in the South) was a decisive victory for the rebels, as Lee had managed a strategic offensive against an enemy force (Pope and McClellan’s) twice the size of his own.
