— Confederate James Longstreet abandoned his attempted siege of Knoxville, Tenn., on Dec. 4, 1863, withdrawing from the area after his failed bid to weaken the Union’s growing grip on the state. The withdrawal of Confederate forces was closely watched by pursuing Union forces. Although the Confederate attempt to take Knoxville had ended, the fighting was not yet over in this corner of Tennessee. More skirmishing and battles would continue in the cold days of December 1863 as Longstreet’s forces clashed with Union forces at various sites. But then Longstreet would pull out of the area entirely and have his fighters settle into winter encampments as the Civil War dragged on 150 years ago this week.
