Commanded by Col. Hugh T. Reid, (Wounded).
This regiment arrived at Pittsburg Landing on the morning of April 6, 1862. It disembarked, formed on the bluff, and there received its first ammunition. It remained in this position about an hour, when under the orders of General Grant, and conducted by one of his staff officers, it marched to join McClernand's (1st) Division. It entered the field to the right of this monument near Oglesby's headquarters and while crossing it was fired upon by artillery and musketry. It formed line of battle and advanced under fire into the woods. Its colonel commanding officially reported that the regiment held its position from 10 o'clock in the forenoon until 12 o'clock noon, and then under orders retired to a new line. Portions of the regiment fought with other divisions later in the day and on Monday. Present for duty 760. Its loss was 2 officers and 19 men killed; 7 officers and 149 men wounded; 2 officers and 6 men captured or missing; total 185.
