Gibson’s brigade begins to fall back about this time.  Some regiments maintain that they stayed on the line until after dark, which is undoubtedly the case.  However, the brigade’s assault was pressed just as hard as Hazen’s, and they have suffered even more casualties.  But in half of an hour, the effectiveness of the brigade is spent.  The ravine is chocked with soldiers taking cover wherever they can.  The section of Key’s Battery firing down the length of the ravine devastates the Union troops there.  Singly, in pairs, and in small groups, many of Gibson’s brigade falls back to their starting point.  Just as many probably remain in the ravine waiting for nightfall.

          Wood finally orders his last brigade under Colonel Knefler into the fight.  However, assaulting the Confederate position is out of the question.  They have orders not to charge the Confederate position, but to maintain the Union line until nightfall so that the wounded and trapped can safely make their way to the rear.  The 86th Indiana is left behind to guard the right rear of the brigade

          Scribner’s regiments make it to the top of the ridge near the Pickett House and stop.  They deploy skirmishers a short distance ahead, but they do not go very far.  Probably no farther than the stream at the bottom of the hill.  Had the brigade made it his far an hour earlier they might have been able to help Hazen’s men in the cornfield.  As it is, they are far too late.

          Walthall's Brigade forms a supporting line behind Granbury.  The 4^th Louisiana retreats from the woods and falls in between the 8^th & 19^th Arkansas and the 33^rd Alabama.
