fort after their flag had been planted at the top of the wall. After several bayonet charges, the Union attackers finally carried the works by sheer force of numbers and, after desperate hand-to-hand combat, forced the surviving defenders to surrender. Union veterans reported that the interior of the fort was a pool of blood with dead and dying men strewn about in its small area by the time the surviving Confederates finally surrendered. As the assault on Fort Gregg concluded, Turner's Third Brigade under Brigadier General Thomas M. Harris attacked Fort Whitworth, where Confederate Brigadier General Nathaniel Harris was in command. The defenders of Fort Whitworth had been shooting at the left and rear of the Union force gathered at the western fringes of Fort Gregg while the battle for that fort continued. Thomas Harris's troops fired into Fort Whitworth but did not try to storm it during the battle for Fort Gregg. Fort Whitworth fell soon after Fort Gregg was taken. As the battle for Fort Gregg was ending, Wilcox had ordered the defenders to retreat from Fort Whitworth. Only 69 or 70 Confederates were left to surrender by the time Brigadier General Thomas Harris's men finally charged Fort Whitworth and easily entered it, finding only two dead and two wounded Confederate soldiers with those who were left to surrender. About 15 other Confederate prisoners were taken outside the fort. Gibbon reported that 55 Confederates were killed at Fort Gregg and about 300 captured, many of them wounded, along with two guns and several flags. Gibbon's loss for the day, mostly at the two forts, was 122 killed, 592 wounded, for a total of 714. The entire attack on Fort Gregg took about two hours. Yet, the defenders of Forts Gregg and Whitworth bought some valuable time which allowed Field's division and a few other defenders to occupy the Dimmock Line defenses. As Confederate reinforcements arrived, Field's division of Longstreet's corps, two brigades from Gordon's corps and some of General Wilcox's men occupied the main Confederate works on the Dimmock Line. When the VI Corps advanced to Gibbon's left at the start of the attack on Fort Gregg, only Confederate artillery fire from Lieutenant Colonel William T. Poague's Battery, directed by Confederate staff officer Giles Buckner Cooke opposed them. The battery was operating from a position next to Lee's command post at the Turnbull House, also known as Edge
