At two o'clock P.M., March 5th, General Curtis received intelligence that Van Dorn had begun his march. Orders were immediately sent to the divisions and detachments to concentrate on Davis' division. Carr moved at 6 P.M., and arrived at 2 A.M. Sigel deferred moving till two o'clock A.M., and at Bentonville halted, himself with a regiment of infantry, the Twelfth Missouri, Elbert's light battery, and five companies of cavalry, till ten o'clock, two hours after the rear of his train had passed through the place. By this time Van Dorn's advance guard had arrived, and before Sigel could form had passed around to his front, at the same time enveloping his flanks. By the skilful disposition of his detachment, and the admirable conduct of the men, Sigel was able to resume and continue his march, an unbroken skirmish, rising at times into engagement, from half-past ten o'clock till half-past three, when he was joined by reinforcements which General Curtis had hurried back to him. The line was formed, facing to the south, on the crest of the bluffs overlooking the Valley of Sugar Creek, Sigel being on the right, next to him Ashboth, then Davis, and Carr being the left. The position was entrenched, and the approaches were obstructed by felled timber. One foraging party of 250 men and one gun did not return till after the battle, so that Curtis' force engaged was just 10,250 men and forty-eight guns. Van Dorn did not assault that evening. By dawn next day it was ascertained that he had made a great detour by the west, and was coming up on the right and rear. Curtis faced his line to the rear and wheeled to the left, so that his new line faced nearly west; the original right flank, now the left, was scarcely moved, and Carr's division had become the right. Colonel Osterhaus, with three regiments of infantry and two batteries, was despatched from Sigel's division to aid a regiment of cavalry and a flying battery that had been quickly sent to retard the enemy's centre and give Carr's division time to deploy. Osterhaus met the cavalry returning, and threw his detachment against the advancing line. The picket posted at Elkhorn tavern, where Carr was to deploy, was attacked and driven back, and Carr's division had to go into line under fire. Osterhaus found himself opposed to the corps of McCulloch and McIntosh, and was about being overwhelmed when Davis' division moved to his support. Pea Ridge is in places covered with timber and brush, in places intersected by deep ravines, and a portion of it was a tangle of fallen timber, marking the path of a hurricane. Manoeuvring was not easy, and detours were required in reinforcing one part of the line from another. The contest on the field, where Davis and Osterhaus were opposed to McCulloch and McIntosh, was fierce and determined until McCulloch and McIntosh were killed. Their numerous, but partially disciplined followers lost heart and direction, and before the close of
