To the left we were slower in finding the enemy. They had been compelled to travel some distance to get out of gunboat range. Nelson moved his division about the same time Wallace opened on the Rebel battery, forming in line of battle, Ammon's Brigade on the extreme left, Bruce's in the centre, and Hazen's to the left. Skirmishers were thrown out, and for nearly or quite a mile the division thus swept the country, pushing the outlying Rebels before it, till it came upon them in force. Then a general engagement broke out along the line, and again the rattle of musketry and thunder of artillery echoed over the late silent fields. There was no straggling this morning. These men were better drilled than many of those whose regiments had broken to pieces on the day before, and strict measures were taken, at any rate, to prevent the miscellaneous thronging back to places of safety in the rear. They stood up to their work and did their duty manfully. It soon became evident that, whether from change of commanders or some other cause, the Rebels were pursuing a different policy in massing their forces. On Sunday the heaviest fighting had been done on the left. This morning they seemed to make less determined resistance here, while toward the centre and right the ground was more obstinately contested, and the struggle longer prolonged. Till half-past ten o'clock, Nelson advanced slowly but steadily, sweeping his long lines over the ground of our sore defeat on Sunday morning, and forward over scores of Rebel dead, resistlessly pressing back the jaded and wearied enemy. The Rebels had received but few reinforcements during the night, their men were exhausted with their desperate contest of the day before, and manifestly dispirited by the evident fact that notwithstanding their well-laid plans of destruction in detail, they were fighting Grant and Buell combined. Gradually, as Nelson pushed forward his lines under heavy musketry, the enemy fell back, till about half-past ten, when, under cover of the heavy timber and a furious cannonading, they made a general rally. Our forces, flushed with their easy victory, were scarcely prepared for the sudden onset, where retreat had been all they had been seeing before. Suddenly, the Rebel masses were hurled against our lines with tremendous force. Our men halted, wavered, and fell back. At this juncture, Captain Terrill's regular battery came dashing up. Scarcely taking time to unlimber, he was loading and sighting his pieces before the caissons had turned, and in an instant was tossing shell from twenty-four pound howitzers into the compact and advancing Rebel ranks.
