Description: |
Reeling from their defeat at Champion Hill, the Confederates reached Big Black River Bridge, the night
of May 16-17. Lt. Gen. John C. Pemberton ordered Brig. Gen. John S. Bowen, with three brigades, to man the
fortifications on the east bank of the river and impede any Union pursuit. Three divisions of Maj. Gen. John A.
McClernand’s XIII Army Corps moved out from Edwards Station on the morning of the 17th. The corps
encountered the Confederates behind breastworks and took cover as enemy artillery began firing. Union Brig. Gen.
Michael K. Lawler formed his 2nd Brigade, Carr’s Division, which surged out of a meander scar, across the front of
the Confederate forces, and into the enemy’s breastworks, held by Vaughn’s East Tennessee Brigade. Confused
and panicked, the Rebels began to withdraw across the Big Black on two bridges: the railroad bridge and the
steamboat dock moored athwart the river. As soon as they had crossed, the Confederates set fire to the bridges,
preventing close Union pursuit. The fleeing Confederates who arrived in Vicksburg later that day were disorganized.
The Union forces captured approximately 1,800 troops at Big Black, a loss that the Confederates could ill-afford.
This battle sealed Vicksburg’s fate: the Confederate force was
bottled up at Vicksburg. |
