I was on camp guard all last night, on the second relief. Troops were coming in all night. This morning about daylight the Sixth Division was ordered out, and marching out about two miles to the northwest, we met the rebels in force and formed a line of battle. Our pickets having been attacked about sunrise, the battle now commenced in earnest and lasted all day. There was some hard fighting in the afternoon, particularly off on the right, and our men soon fell back to the first line of breastworks. About 3 p. m. the Iowa Brigade was flanked and had to fall back to the second line of breastworks, but the brigade, with the exception of the Fifteenth Regiment, did not get into the thick of the fight.1 The fighting continued till dark, and after that there was some very heavy cannonading.
1 The record of the losses of our brigade is as follows: The Fifteenth, eleven killed, sixteen wounded; the Thirteenth, one killed, fourteen wounded; the Sixteenth, one killed, twenty-one wounded; the Eleventh, three killed, eight wounded. — A. G. D.
