The brigades of of the XX th Corps began to arrive on the field. The engagement ment turned into a hotly contested fight at close range, the outcome hanging in the balance.
Hardee halted his attack briefly to realine his units, the he advanced again, but much of the impetus from the orginal assault had
dissipated. As his men crossed the Goldsboro rd. they struck the fresh units of the XX th Corp and recoiled.
Holks advanced from his blocking position to join the attack , and once more the confederates gave away. Bragg however recalled Hokeand ordered him to focus on a frontal assault against a federal redoubt.
On parts of the field, the fighting was hand to hand, men clubed each other with muskets because there was no timeto reload. The confederates attacked fewer than five times, but each time the patch work federal line held. The firing petered out with falling darkness, and the confederates with drew to their orginal line.
That night Slocum brought up more reinforcements and it became clear that nuthing further could be accomplised on that particular battlefield.
Still Johnston refused to withdrawl. He changed his postion to defend against the expected arrival of Slocum's reinforcements, but he stubernly held his postion for two more days. By the afternoon of March 20th the federals had 4 corps on the field and they attacked the rebel lines several times without success. At one point a federal div. charged toward a weak point in the rebel line and Hardee sent a regiment to plug the hole.
Only days before before hardee had reluctantly given his own 16 yr old son permission to leave school and join a
cav. reg. It was that reg. whose charge now blunted the federal spearhead. The federals withdrew, but Hardee's son fell mortally wounded.
The next day Sherman sent a corp around Johnstons flank to cut off his line of retreat which left Johnston no option but to withdrawl , and that night he pulled the army back from Bentoville toward Raleigh.
Only on terms of its impact on moral can Bentonville be called a Confederate victory Shermon held the ground afterward and the attacking army suffered most of the casualties.
The Confederates lost a total of 260, Union loses were 1646. But Sherman's men learned that the war was not yet over and that the Confederate army was still dangerous.
