Colonel Vandever held his line at the Elkhorn Tavern in the edge of thick timber on the main Fayetteville road until late in the afternoon, fighting desperately, when the enemy, taking advantage of the timber as a blind, by largely superior numbers, drove him back across an open field to a line of woods in his rear and in my rear, which he successfully held. I was not aware of his movement until the fire in that direction slackened, and I sent out my adjutant, Lieutenant James A. Williamson (afterwards a Brevet Major-General), who returned and reported that the enemy were in possession of that field; in fact, he ran right into them and received their fire, but got back to me safely. It was then nearly dark. The fire on my front had slackened, and my Brigade was almost entirely out of ammunition. I immediately ordered them to form in column and led them right out from the right, moving in the direction where Vandever's Brigade had formed in its new position. As I moved out I passed right in sight of a column of the Confederate forces, who evidently had come out of the hollow and were forming to again attack Vandever. They probably thought I was a portion of their force, for they made no demonstration towards me, and I passed right by them. As I passed out into the open I could see that General Asboth, who had been brought there by General Curtis, was forming to attack at the Elkhorn Tavern again; and I met General Curtis, who seemed astonished to find me with my force intact. He asked me where I was going. I told him that I was out of ammunition, and that I was bringing out my force to form it on the new line. Paying the command a high compliment, he immediately ordered me to fix bayonets and to charge on the enemy at the same time that Asboth with his reinforcement moved down the Fayetteville road towards the Elkhorn Tavern. I immediately did this, and passed right back over the field where I had been fighting, but found no enemy. They had evidently left my front at the same time I retired, and I returned and went into line on the right of Vandever's Brigade, probably 500 feet in the rear of the original line, and there we laid all night under arms.
Van Dorn's plan of attack was to throw the Arkansas forces under McCullough and McIntosh on Curtis's right, facing the Little Cross Hollow road, while at the same time General Price with his force moved around us by the Little Cross Timber road to our rear and attacked from the Cross Timbers.
When passing through Little Cross Timber Hollow Price struck the timber blockade, and, as he shows in his report, was held there for a long time before he could clear out the roads and get his forces and artillery through. This delayed his attack in the rear until nearly 10 o'clock in the morning. The two forces of McCullough and Price were separated by a high ridge by the name of Pea Ridge, over which it was impracticable for them to connect, and, therefore, the two attacks were separate and not in concert.
General McCullough, in attacking from the west, struck General Jeff C. Davis's Division. Davis had a Division of troops that had been thoroughly drilled. He was a very competent officer and handled them with great skill, and the attack of McCullough and McIntosh, though desperate, was without avail, both rebel commanders being killed in the attack, which took all the fight out of the Arkansas troops and made their attacks towards evening of very little effect. Davis pursued them so energetically that after the death of their commanders they straggled off towards Arkansas and no more fighting occurred on that flank.
General Siegel's two Divisions had remained facing Sugar Creek. General Curtis had endeavored to bring them forward, but without avail. A Brigade of General Osterhaus's Division aided General Davis during the latter part of the day, but the Brigade from Asboth's Division did not get into line to help Carr until nearly dark, although General Curtis went in person for them. Colonel Carr's troops had been marching two nights before the battle, and on the night of the 7th he asked General Curtis to relieve them, so they could get some sleep. General Curtis promised they should be relieved by one of General Siegel's Divisions, but they held the line all that night right where they were formed, and when we looked for our relief the next morning we learned that General Siegel and his troops were nearly a mile in our rear, taking their breakfast.
The general plan of General Curtis's attack on the morning of the 8th was for a combined movement on Price's Army by both of General Siegel's Divisions, and General Davis, who had been brought over to our front, holding Carr's Division in reserve. We waited a long time for General Siegel to get into position; and in fact before he got into position Colonel Carr had been brought out from the reserve and placed on the right of Davis. The enemy opened out upon us, and my Brigade holding the right I commenced swinging my line in over the ground I had fought over the day before, and discovered that the enemy were withdrawing from us; were not standing and giving battle; and the fighting on the morning of the 8th was merely a fight of Price's rear-guard to enable him to withdraw by the Huntsville road, he having received orders that morning from Van Dorn to do so, Van Dorn notifying Price that this was necessary, as the Arkansas troops, after the death of McCullough and McIntosh, had most of them retreated to the south, leaving Price's Army the only force intact in our rear, so that he now had the difficult problem of getting away from us.
The fighting lasted but a short time, mostly with artillery, and occasioned very little loss for that day. We soon discovered the rebels fleeing over the hills and down the White River Road, and being nearest to that road I immediately started my Brigade after them. I had not proceeded far when I received an order from General Curtis to return and hold the battle-field. I was a good deal astonished at this, as I could see the enemy demoralized in my front, with their baggage-trains and their artillery, and I had no doubt, (as I knew the country, having had a detachment stationed at Blackburn's Mills, at the crossing of White River, supplying our Army with forage and grain before the battle,) that I could capture this portion of the army before it could make a crossing of White River.
When I arrived on the battle-field General Curtis told me that General Siegel and his Divisions had gone to the rear towards Cassville; in fact, I myself heard him give one of the Brigades that was passing an order to halt there, which they did not obey, but kept on. General Siegel wrote back advising Curtis to form his new line in the rear of Cross Timbers, as Van Dorn might return to the fight, but Curtis instructed Colonel Carr's Division to remain on the field and hold it, which it did. General Curtis afterwards made very severe complaints to General Halleck of the actions of General Siegel, and in answer General Halleck wrote as follows:
I was by no means surprised at General Siegel's conduct before the battle of Pea Ridge. It was plainly in keeping with what he did at Carthage and Wilson's Creek. After your expedition started I received documentary proof from Captains Sturgis, Schofield, and Totten, and a number of other officers, in regard to his conduct on those occasions, which destroyed all confidence in him. It was for that reason that I telegraphed to you so often not to let Siegel separate from you. I anticipated that he would try to play you a trick by being absent at the critical moment. I wished to forewarn you of the snare, but I could not then give you my reasons. I am glad you prevented his project and saved your army. I cannot describe to you how much uneasiness I felt for you. You saved your army and won a glorious victory by refusing to take his advice.
Captain Kinsman, of Company B, Fourth Iowa, who was holding Pea Ridge, and witnessed the battle from that point, and could look down upon Carr's Division, described the battle in the rear as follows:
