General Longstreet formed his line of battle. Hood's corps included the Bushrod Johnson and the Sons of Erin were on the right flank and in the lead position. Mean while the famous gap in the union line was opened. All Confederates start the attack. The 10th Tennessee with Colonel Grace leaded them moved to the west and headed into a patch of woods. Coming out they met some incoming Union shells from the 1st Missouri Battery (U.S). Grace never backing down headed right for the guns which had very little infantry support. Union support came up  and the 10th Tennessee found themselves in hand to hand combat. The Confederates kept moving westward near Missionary Ridge; the Sons of Erin found themselves at Steedman's Hill there the headed down the north end and met the Union forces consisting of men from Ohio and Illinois. The 10th and 30th Tennessee came in contact with Lt. Colonel Darius Warner's Ohioans. In Charge Colonel Grace knowing his was out numbered withdrew to the original defensive line on the south side of the hill. Major O'Neill's sharpshooter repulsed the attack but were not enough. On the Eastern end Tennessains were driven off the hill; on the west end the Confederate forces had no chance. So Grace ordered retreat of the 10th and 30th Tennessee. During the fashionalbe withdrawal Grace who was mounted had his horse shot underneath him; he fell and became immoblized. Seeing this a Ohio skirmish line fired at the Irish. The Irish sharpshooter return fired while First Lieutenant Robert P. Seymour dragged the Colonel up on to his horse. The fight at Steedman's Hill was the last engagement for the 10th Tennesee, Sons of Erin during the Battle of Chickamauga
