Both armies had now reached the soil of Arkansas. The rebels being rapidly reinforced by regiments which had been stationed in that State and the Indian Territory, General Price was in a better position to give battle. Upon mature deliberation, General Curtis selected Sugar Creek as the best position he could take to withstand any attack which might be made upon him. The enemy had, in the mean time, taken up his position in the locality of Cross Hollow, which was peculiarly adapted to his mode of warfare. But this was not long permitted, for on learning that the Union troops were turning their flank by way of Osage Spring, Price’s followers again decamped in hot haste, leaving behind a considerable quantity of supplies and munitions of war. By this time the lines of the Union army extended nearly ten miles. The right was under General Sigel, resting at the Osage Springs, and the left under Colonel Carr, extending to Cape Benjamin. Colonel Carr’s headquarters were at Cross Hollows. Having abandoned Cross Hollows, General Price took up a fresh position in the Boston Mountains, a high range that divides the waters of the White Mountains and Arkansas, where every effort was made to rally the dispirited rebels and augment the ranks of his command. Here it was that he was reinforced by Generals McCullough, Pike and Van Dorn. These combined armies were estimated at thirty-five thousand men. Matters remained comparatively quiet until the 5th of March, when General Curtis received information that the rebels were advancing to give battle. The information proved correct, and the 6th, 7th and 8th will long be held in remembrance as the anniversary of one of the bloodiest conflicts of the war. Pea Ridge is in the extreme north-west part of Arkansas, situated in Benton, the corner county of the State. A range of hills—a spur of the Ozark Mountains—sweeps from Missouri into this corner of the State, and from thence branches into the Indian Territory, where the section known as the Boston Mountains is found. Sugar Creek, where the battle commenced, is situated close to Bentonville, the capital of the county on the north. Pea Ridge is also adjacent to the same town, and forms a part of the mountain range just described.
