June 3. A welcome order from the headquarters of the Army of the Potomac transferred the Twenty-ninth Regiment from the Fifth to the Ninth Corps, and the regiment reported to General Burnside in the afternoon. On this day was fought the terrible battle of Cold Harbor, in which the Ninth Corps bore the brunt of the battle on the right, losing in the engagement over one thousand killed and wounded. Owing to the lateness of the hour on which the order of transfer reached the regiment, it did not arrive at Burnside’s lines in season to take a very active part in the battle; but it moved promptly, however, and lay in support behind some old breastworks. One of our batteries, which was posted in the rear of these works, engaged in shelling the enemy, wounded Lawrence T. Chickey and Conrad Homan of Company A. Sergeant Samuel C. Wright of Company E was also wounded here by a rifle-shot from the enemy’s lines.
