day gave way before the persistent and orderly attack, and finally broke and left the field. Carr's division was opposed to Price's corps, and Van Dorn gave his personal attention to that part of the field. Gallantry and determination could not prevail against gallantry and determination backed by superior numbers. Bit by bit, first on one flank, then the other, he receded. Curtis sent his body-guard, then the camp-guard to reinforce him, and then a small reserve that had been guarding the road to the rear. Carr had sent word he could not hold out much longer. Curtis sent word to persevere, and went in person to the left, where Sigel with his two divisions had not yet been under fire, and hurried Ashboth over to Carr's relief. Carr had been gradually pushed back nearly a mile; Van Dorn had been concentrating upon him, resolved to crush him. Curtis, returning with Ashboth, met the Fourth Iowa marching to the rear, in good order. Colonel Dodge explained that ammunition was exhausted, and he was going for cartridges. "Then use your bayonets," was the reply, and the regiment faced again to the enemy and steadily advanced. It was about five o'clock P.M. when Ashboth reached Carr's line and immediately opened fire. The combat continued till dark set in. As it was evident that Van Dorn was throwing his whole force upon the position held by Carr, General Curtis took advantage of the cessation during the night to re-form his line. Davis and Osterhaus were brought to join Carr's left, and Sigel was ordered to form on the left of Osterhaus. When the sun rose, Sigel was not yet in position, but Davis and Carr began attack without waiting. General Curtis, riding to the front of Carr's right, found in advance a rising ground which gave a commanding position for a battery, posted the Dubuque battery there, and moved forward the right to its support. Sigel, coming up with the divisions of Osterhaus and Ashboth on Davis' left, first sent a battery forward, which by its rapid fire repelled the enemy in its front, and then with its deployed supports wheeled half to the right. Another battery pushed forward repeated the manoeuvre with its supporting infantry. The column thus deployed on the right into line, bending back the enemy's right wing in the execution of the movement--each step in the deployment gaining space for the next succeeding step. The line as now formed, from the Dubuque battery on the right to Sigel's left, formed a curve enclosing Van Dorn's army. Under this concentric fire Van Dorn's entire force before noon was swept from the field to find refuge in the deep and tortuous ravines in his rear. Pursuit was fruitless. McCulloch's command, scattering in all directions, was irretrievably dispersed. Van Dorn, with Price's corps and other troops, found outlet by a ravine leading to the south, unobserved by the national troops, went into camp ten miles off on the prairie, and sent in a flag of truce to bury his dead.
