Wilson's men were initially pushed back in some confusion, but Gregg had concealed a heavy line of skirmishers armed with repeating carbines in a brushy ravine. His men poured forth a destructive fire, halting the final Confederate advances, assisted by some of Wilson's men who turned the flank of the attacking column. Federal horse artillery made sure that the Confederate infantry no longer was a threat, and three mounted cavalry regiments skirmished with approaching enemy cavalry, turning them aside and protecting the rear. Brig. Gen. Gordon was mortally wounded in the fighting and died on May 18.
