Nice catch - Battle of Gainesville was the other name for Brawner's Farm. My mistake.My understanding is that Brawner's Farm and Groveton are actually two different engagements, the first (Brawner's) occurring on Aug. 28 as the "run-up" and the second (Groveton) being the "other" Federal name for Second Manassas Aug. 29-30. Brawner's Farm was outside the Federal lines during the main battle and was where Jackson's divisions (including the Stonewall Brigade) had "ambushed" the Federal divisions of King (including the Iron Brigade) and Doubleday. Groveton was a tiny hamlet that wound up on the Federal far left flank behind Porter's Fifth Corps assaulting Jackson's line at the Unfinished Railroad. Although both were on the Warrenton Turnpike they were a distance apart from each other.
