Major Cavender moved his pieces, and then returned the fire with greater zeal. Through the forenoon the forests echoed the terrific cannonade, mingled with the sharp crack of the riflemen, close under the breastworks. At noon the infantry fight began. West of the town, in addition to the line of rifle-pits and breastworks, the Rebels had thrown up a small redoubt, behind which their batteries were securely posted. General McClernand decided to attack it. He ordered Colonel Wallace to direct the assault. The Forty-eighth, Seventeenth, and Forty-ninth Illinois regiments were detached from the main force, and placed under the command of Colonel Hayne, of the Forty-eighth, for a storming party. McAllister's battery was wheeled into position to cover the attack. They form in line at the base of the hill. The shells from the Rebel batteries crash among the trees. The Rebel riflemen keep up a rattling fire from the thickets. The troops are fresh from the prairies. This is their first battle, but at the word of command they advance across the intervening hollows and ascend the height, facing the sheets of flame which burst from the Rebel works. They fire as they advance. It is not a rush and a hurrah, but a steady movement. Men begin to drop from the line, but there is no wavering. They who never before heard the sounds of battle stand like veterans. The Rebel line in front of them extends farther than their own. The Forty-fifth Illinois goes to the support of Wallace. The Rebels throw forward reinforcements. There is a continuous roll of musketry, and quick discharges of cannon. The attacking force advances nearer and still nearer, close up to the works. Their gallantry does not fail them; their courage does not falter; but they find an impassable obstruction,--fallen trees, piles of brush, and rows of sharp stakes. Taylor's battery gallops up the road, and opens a rapid fire, but the Rebel sharpshooters pick off his gunners. It is madness to remain, and the force retires beyond the reach of the Rebel musketry; but they are not disheartened. They have hardly begun to fight. Colonel Birges's sharpshooters are sent for. They move down through the bushes, and creep up in front of the Rebel lines. There are jets of flame and wreaths of blue smoke from their rifles. The Rebel pickets are driven back. The sharpshooters work their way still nearer to the trenches. The bushes blaze. There are mysterious puffs of smoke from the hollows, from stumps, and from the roots of trees. The Rebel gunners are compelled to let their guns remain silent, and the infantry dare not show their heads above the breastworks. They lie close. A Rebel soldier raises his slouched hat on his ramrod. Birges's men see it, just over the parapet. Whiz! The hat disappears. The Rebels chuckle that they have outwitted the Yankee. "Why don't you come out of your old fort?" shouts a sharpshooter, lying close behind a tree. "Why don't you come in?" is the answer from the breastworks.
