The difficult strategic situation of the Federal armies after Chickamauga enabled Bragg to detach a force under Longstreet which aimed to drive Burnside out of East Tennessee and did shut him up in Knoxville, which he defended successfully. These views, taken after Longstreet's withdrawal on December 3, include one of Strawberry Plains, which was on his line of retreat. Barnard was photographer of the chief engineer's office, Military Division of the Mississippi, and his views were transmitted with the report of the chief engineer of Burnside's army, April 11, 1864.
