As soon as the camp of my brigade was pitched at Booneville, I began to scout in every direction, to obtain a knowledge of the enemy's whereabouts and learn the ground about me. My standing in drawing at the Military Academy had never been so high as to warrant the belief that I could ever prove myself an expert, but a few practical lessons in that line were impressed on me there, and I had retained enough to enable me to make rough maps that could be readily understood, and which would be suitable to replace the erroneous skeleton outlines of northern Mississippi, with which at this time we were scantily furnished; so as soon as possible I compiled for the use of myself and my regimental commanders an information map of the surrounding country. This map exhibited such details as country roads, streams, farmhouses, fields, woods, and swamps, and such other topographical features as would be useful. I must confess that my crude sketch did not evidence much artistic merit, but it was an improvement on what we already possessed in the way of details to guide the command, and this was what I most needed; for it was of the first importance that in our exposed condition we should be equipped with a thorough knowledge of the section in which we were operating, so as to be prepared to encounter an enemy already indicating recovery from the disorganizing effects of his recent retreat.
In the immediate vicinity of Booneville the country was covered with heavy forests, with here and there clearings or intervening fields that had been devoted to the cultivation of cotton and corn. The ground was of a low character, typical of northeastern Mississippi, and abounded in small creeks that went almost totally dry even in short periods of drought, but became flooded with muddy water under the outpouring of rain peculiar to a semi-tropical climate. In such a region there were many chances of our being surprised, especially by an enemy who knew the country well, and whose ranks were filled with local guides; and great precautions as well as the fullest information were necessary to prevent disaster. I therefore endeavored to familiarize all with our surroundings, but scarcely had matters begun to shape themselves as I desired when our annihilation was attempted by a large force of Confederate cavalry.
On the morning of July 1, 1862, a cavalry command of between five and six thousand-men, under the Confederate General James R. Chalmers, advanced on two roads converging near Booneville. The head of the enemy's column on the Blackland and Booneville road came in contact with my pickets three miles and a half west of Booneville. These pickets, under Lieutenant Leonidas S. Scranton, of the Second Michigan Cavalry, fell back slowly, taking advantage of every tree or other cover to fire from till they arrived at the point where the converging roads joined. At this junction there was a strong position in the protecting timber, and here Scranton made a firm stand, being reinforced presently by the few men he had out as pickets on the road to his left, a second company I had sent him from camp, and subsequently by three companies more, all now commanded by Captain Campbell. This force was dismounted and formed in line, and soon developed that the enemy was present in large numbers. Up to this time Chalmers had shown only the heads of his columns, and we had doubts as to his purpose, but now that our resistance forced him to deploy two regiments on the right and left of the road, it became apparent that he meant business, and that there was no time to lose in preparing to repel his attack.
Full information of the situation was immediately sent me, and I directed Campbell to hold fast, if possible, till I could support him, but if compelled to retire he was authorized to do so slowly, taking advantage of every means that fell in his way to prolong the fighting. Before this I had stationed one battalion of the Second Iowa in Booneville, but Colonel Edward Hatch, commanding that regiment, was now directed to leave one company for the protection of our camp a little to the north of the station, and take the balance of the Second Iowa, with the battalion in Booneville except two sabre companies, and form the whole in rear of Captain Campbell, to protect his flanks and support him by a charge should the enemy break his dismounted line.
While these preparations were being made, the Confederates attempted to drive Campbell from his position by a direct attack through an open field. In this they failed, however, for our men, reserving their fire until the enemy came within about thirty yards, then opened on him with such a shower of bullets from our Colt's rifles that it soon became too hot for him, and he was repulsed with considerable loss. Foiled in this move, Chalmers hesitated to attack again in front, but began overlapping both flanks of Campbell's line by force of numbers, compelling Campbell to retire toward a strong position I had selected in his rear for a line on which to make our main resistance. As soon as the enemy saw this withdrawing he again charged in front, but was again as gallantly repelled as in the first assault, although the encounter was for a short time so desperate as to have the character of a hand-to-hand conflict, several groups of friend and foe using on each other the butts of their guns. At this juncture the timely arrival of Colonel Hatch with the Second Iowa gave a breathing-spell to Campbell, and made the Confederates so chary of further direct attacks that he was enabled to retire; and at the same time I found opportunity to make disposition of the reinforcement to the best advantage possible, placing the Second Iowa on the left of the new line and strengthening Campbell on its right with all the men available.
In view of his numbers, the enemy soon regained confidence in his ability to overcome us, and in a little while again began his flanking movements, his right passing around my left flank some distance, and approaching our camp and transportation, which I had forbidden to be moved out to the rear. Fearing that he would envelop us and capture the camp and transportation, I determined to take the offensive. Remembering a circuitous wood road that I had become familiar with while making the map heretofore mentioned, I concluded that the most effective plan would be to pass a small column around the enemy's left, by way of this road, and strike his rear by a mounted charge simultaneously with an advance of our main line on his front. I knew that the attack in rear would be a most hazardous undertaking, but in the face of such odds as the enemy had the condition of affairs was most critical, and could be relieved, only by a bold and radical change in our tactics; so I at once selected four sabre companies, two from the Second Michigan and two from the Second Iowa, and placing Captain Alger, of the former regiment, in command of them, I informed him that I expected of them the quick and desperate work that is usually imposed on a forlorn hope.
To carry out the purpose now in view, I instructed Captain Alger to follow the wood road as it led around the left of the enemy's advancing forces, to a point where 'it joined the Blackland road, about three miles from Booneville, and directed him, upon reaching the Blackland road, to turn up it immediately, and charge the rear of the enemy's line. Under no circumstances was he to deploy the battalion, but charge in column right through whatever he came upon, and report to me in front of Booneville, if at all possible for him to get there. If he failed to break through the enemy's line, he was to go ahead as far as he could, and then if any of his men were left, and he was able to retreat, he was to do so by the same route he had taken on his way out. To conduct him on this perilous service I sent along a thin, sallow, tawny-haired Mississippian named Beene, whom I had employed as a guide and scout a few days before, on account of his intimate knowledge of the roads, from the public thoroughfares down to the insignificant by-paths of the neighboring swamps. With such guidance I felt sure that the column would get to the desired point without delay, for there was no danger of its being lost or misled by taking any of the many by-roads which traversed the dense forests through which it would be obliged to pass. I also informed Alger that I should take the reserve and join the main line in front of Booneville for the purpose of making an advance of my whole force, and that as a signal he must have his men cheer loudly when he struck the enemy's rear, in order that my attack might be simultaneous with his.
I gave him one hour to go around and come back through the enemy, and when he started I moved to the front with the balance of the reserve, to put everything I had into the fight. This meant an inestimable advantage to the enemy in case of our defeat, but our own safety demanded the hazard. All along our attenuated line the fighting was now sharp, and the enemy's firing indicated such numerical strength that fear of disaster to Alger increased my anxiety terribly as the time set for his cheering arrived and no sound of it was heard.
