Also called the Sandbag Battery, Confederate Redoubt No. 5 was originally commanded by Lt. Andrew Hargrove of Lumsden's Tuscaloosa Battery, Company F, 2nd Alabama Light Artillery Battalion. During the early stages of the battle, Lumsden's Battery was relocated 200 yards west of this location to strengthen the far left of the Confederate line. Afterwards, the same artillerists who manned Redoubt No. 4 also manned the Sandbag Battery. The redoubt was armed with four 3-inch ordinance rifles, while Lumsden's new position had three mortars and four 6-pounder cannons that the men jokingly called popguns. Capt. Thomas Perry's Marion, Florida, Light Artillery relieved Lumsden's Battery on April 6, 1865. During the Battle of Spanish Fort, Ector's Infantry Brigade occupied the earthworks on the Confederate left flank under the temporary command of Col. David Coleman. The 29th and 39th North Carolina Infantry Regiments held the brigade's right, while on the left were the Texas regiments of the 9th Texas Infantry and the 10th, 14th, and 32nd Texas dismounted Cavalry. At dusk on April 8, 1865, Lt. Col. William Bell's 8th Iowa breached the far left of the Confederate line. After this initial success, Union 3rd Brigade commander Col. James Geddes ordered Lt. Col. Andrew Rogers' 81st Illinois to support the assault. The North Carolina troops, along with 100 Provost Guards, launched a desperate counterattack that stabilized the Confederate line. Provost Marshall Capt. Alfred Clarke was mortally wounded while leading this counterattack. General Gibson then realized his garrison was in danger of being cut off from its only escape route to the Blakeley River, and he decided to evacuate the earthworks during the night.
