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.
