"The enemy having forced the centre line to fall back nearly half way from their camps to the Landing, at a late hour in the afternoon a desperate effort was made by the enemy to turn our left and get possession of the Landing, transports, etc. This point was guarded by the gunboats, Tyler and Lexington, Captains Gwin and Shirk commanding, with four twenty-four-pounder Parrott guns, and a battery of rifled guns. "As there is a deep and impassable ravine for artillery or cavalry, and very difficult for infantry at this point, no troops were stationed here except the necessary artillerists and a small infantry force for their support. Just at this moment the advance of Major-General Buell's column and a part of the division of General Nelson arrived, the two Generals named both being present. An advance was immediately made upon the point of attack, and the enemy was soon driven back. In this repulse, much is due to the presence of the gunboats Tyler and Lexington, and their able commanders, Captains Gwin and Shirk. "During the night the divisions under Generals Crittenden and McCook arrived. General Lew. Wallace, at Camp Landing, six miles below, was ordered, at an early hour in the morning, to hold his division in readiness to move in any direction it might be ordered. At eleven o'clock, the order was delivered to move up to Pittsburgh, but owing to its being led by a circuitous route did not arrive in time to take part in Sunday's action. "During the night all was quiet, and feeling that a great moral advantage would be gained by becoming the attacking party, an advance was ordered as soon as day dawned. The result was the gradual repulse of the enemy at all points of the line, from nine until probably five o'clock in the afternoon, when it became evident the enemy was retreating. Before the close of the action the advance of General T. J. Wood's Division arrived in time to take part in the action. "My force was too much fatigued, from two days' hard fighting and exposure in the open air to a drenching rain during the intervening night, to pursue immediately. Night closed in cloudy and with a heavy rain, making the roads impracticable for artillery by the next morning. General Sherman, however, followed the enemy, finding that the main part of the army had retreated in good order.
