Apropos of this the following memorandum of a staff-officer is interesting and informative:

“I know at the time it was currently reported that General Law said he might have made the attack successfully, but that Jenkins would have reaped the credit of it, and hence he delayed until the enemy got out of the way.”

This has been called a battle, by the other side, but it was only an artillery combat, little, very little, musket ammunition being burnt. The next day the enemy was safely behind his works about Knoxville, except his cavalry under General Sanders and his horse artillery left to delay our march. McLaws’s division reached the suburbs of the city a little after noon, and was deployed from near the mouth of Third Creek as his right, the enemy holding a line of dismounted cavalry skirmishers about a thousand yards in advance of his line of works. Alexander’s artillery was disposed near McLaws’s deployment. Jenkins got up before night and was ordered to deploy on McLaws’s left as far as the Tazewell road, preceded by Hart’s cavalry, which was to extend the line north to the Holston River. General Wheeler came up later and was assigned to line with Colonel Hart.

The city stands on the right bank of the Holston River, on a plateau about one and a half miles in width and extending some miles down south. At Knoxville the plateau is one hundred and twenty feet above the river, and there are little streams called First, Second, and Third Creeks, from the upper to the lower suburbs of the city,—First Creek between the city and East Knoxville, or Temperance Hill; Second Creek between the city and College Hill; Third Creek below and outside the enemy’s lines of defence. The plateau slopes down to the valley through which the railway passes, and west of the valley it rises to the usual elevation. The Confederates were posted on the second plateau, with their batteries of position. The line of the enemy’s works, starting at its lower point on the west bank of the river, was just above the mouth of Second Creek, lying at right angles to the river. It ran to a fort constructed by the Confederates, when occupied by them years before, called Fort Loudon, above the Kingston road, and about a thousand yards in front of the college. East from that point it was about parallel with the river, reaching to Temperance Hill, to Mabry’s Hill, and to the Holston, below the glass-works. An interior line extended from Temperance Hill to Flint Hill on the east, and another on the west, between the outer line and Second Creek. Dams were built across First and Second Creeks, flooding and forming formidable wet ditches over extensive parts of the line. Abatis, chevaux-de-frise, and wire entanglements were placed where thought to be advantageous for the defenders.

The heights on the northeast across the river are much more elevated than the plateaux of the city side, and command all points of the west bank. These were defended at some points by earthworks well manned. From the lower point of the enemy’s line the Confederates extended to his right at the river, conforming to his defensive lines. The part of our line occupied by the cavalry was a mere watch-guard.

Our move was hurried, and our transportation so limited that we had only a few tools in the hands of small pioneer parties, and our wagons were so engaged in collecting daily rations that we found it necessary to send our cavalry down to Lenoir’s for the tools captured there for use in making rifle-pits for our sharp-shooters.

When General Burnside rode to the front to meet us at Lenoir’s he left General Parke in command at Knoxville, and he and Captain Poe, of the engineers, gave attention to his partially-constructed works.

Upon laying our lines about Knoxville, the enemy’s forces in the northeast of his department were withdrawn towards Cumberland Gap, but we had no information of the troops ordered to meet us from Southwest Virginia.
