Baldwin's brigade, leaving the intrenchments at 6 A.M., marched by the right flank out a narrow and obstructed byroad, crossed the valley in front of the works, and, while ascending the slope beyond, encountered what they supposed to be a line of pickets. But Oglesby's hungry men had slept little that cold night, and by simply rising to their feet were in line of battle. Baldwin's brigade, in attempting to deploy, was thrown into confusion, repeatedly rallied, and was thrown into disorder and pushed back before its line was established. Colonel Baldwin, in his report, says that deployment forward into line would have brought his men into such an exposed situation that he threw his regiment first into column of company, then deployed on the right into line, and admits that practising tactics with new troops under fire is a different thing from practice on the drill-ground. The movement that Colonel Baldwin attempted with his leading regiment, the Twenty-sixth Mississippi, is the same that General Sigel accomplished at Pea Ridge with such brilliant effect, where he had by artillery fire to drive back the enemy's line to gain room for each successive deployment. The firing sufficiently notified General McArthur where he was, and, without waiting for orders, he formed his brigade into line on Oglesby's right. Pillow's division, continually filing out from the intrenchments, continually extended his line to his left. McArthur, to gain distance to his right, widened the intervals between his regiments, refused his right, and prolonged it by a skirmish line. Oglesby brought into action Schwartz's battery, then commanded by Lieutenant Gumbart, and the batteries in position in the besieged intrenchments joined in the combat. A tenacious fight, face to face, ensued--so stationary that its termination seemed to be a mere question of endurance and ammunition. General Pillow moved the Twentieth Mississippi by wheeling its left to the front. In this position the regiment suffered so severely that it withdrew and took shelter behind a rising ground. A depression was found by which General B.R. Johnson's brigade could find comparative protection while moving to their left and gaining distance to their front. General McArthur found his right flank turned and his ammunition nearly exhausted, and withdrew his brigade to a new position several hundred yards to his rear. Oglesby moved the Eighteenth Illinois to the right, to partially fill the vacated line, and brought up the Thirtieth Illinois from its position in reserve to take the place left by the Eighteenth. Colonel Lawler, of the Eighteenth, was wounded early in the engagement. Captain Brush, who had succeeded to the command, was wounded while carrying out this movement. The ammunition of the Eighteenth being now nearly gone, it retired in good order to replenish, leaving 44 of its number dead, and 170 wounded on the ground where it had stood.
