The 5th Texas fought in the Second Battle of Bull Run on 28–30 August 1862. On the evening of the 29th, the brigades of Evander M. Law and Hood mounted a reconnaissance in force in which they defeated two Union brigades under John Porter Hatch. Because of the darkness and confusion, Hood's and Law's men were withdrawn to their original positions. The next day at 4:00 pm, James Longstreet and Lee launched a major assault at the Union left flank; it was led by the Texas Brigade. The 1st Texas on the extreme left drifted off and lost touch with the brigade. So the attack was made with the 4th Texas on the left, the 5th Texas on the right, and the 18th Georgia and Hampton's Legion in the center. Hood's brigade smashed Gouverneur K. Warren's 1,000-man brigade. Next, Martin Davis Hardin's Federal brigade tried to block the Texas Brigade's advance. The 300-strong 5th Texas turned Hardin's left flank and forced the Union brigade to flee. The 4th Texas and 18th Georgia overran a Union artillery battery. Next, Hood's brigade encountered Nathaniel McLean's Union brigade atop Chinn Ridge. At this time, the 4th Texas came under blistering fire and pulled out of the fight while the 5th Texas and the other units took cover in some woods. Nathan George Evans's brigade caught up with Hood's Texans, but their attack was repulsed. A further advance by the 5th Texas was stopped cold. It would take several more Confederate brigades to drive McLean's Federals from their position. The Texas Brigade lost 75 killed, 550 wounded, and 13 missing at Second Bull Run.
