I have this noted in my regimental history of the 43rd Tennessee, CSA:

07 04 1863 [Saturday]

At 9 o'clock of the morning of the 4th, my division being one of the three selected to occupy the city, and the signal agreed upon having been displayed along the enemy's line, I marched in and took possession of the works in my immediate front. Several of these were well built, and from their strength could not have been carried by assault without heavy loss. (OR V24, pt. 2, p. 319 Herron’s report)
