griffin's division and the v corps artillery under colonel and brevet brigadier general charles s. wainwright, which had to carry their four guns forward through the mud, finally stopped the confederate advance short of crossing gravelly run. the confederates fell back about 400 yards from the run when they met the fire from griffin and wainwright, although historian ed bearss states that the confederates only meant to make a forced reconnaissance at the run, not to cross it.
