At Port Republic Battlefield, General Stonewall Jackson, with 6,000 Confederates, attacked James Shields' 3,000-man vanguard under E.B. Tyler, which had marched down Luray Valley to join General J.C. Frémont's army. Jackson's first attack by General C.S. Winder's brigade, bolstered by the 7th Louisiana, was repulsed, and in a counterattack the Federals captured one Confederate cannon. Jackson was then reinforced by units from General R.S. Ewell's division, and General Dick Taylor's Louisiana brigade swung east, charged, and captured six guns emplaced at the intersection of U.S.340 and Route 569. The Federals counterattacked and recovered the guns, but after reinforcement by Colonel W.S. Scott's command, Taylor's Louisianians pressed forward again and drove the Federals once more from the cannons. Tyler's troops abandoned the field and retreated toward Conrad's Store, while General I.R. Trimble's and Colonial J.M. Patton's brigades retired across North River and burned the bridge, preventing Frémont from coming to Tyler's assistance.
