The Sharpshooter Regiment trained through the Battle of Iuka without entering that battle. On October 3, 1862, the regiment was on the left flank of Phiffer's Brigade for the Battle of Corinth. Trained as skirmishers and sharpshooters, they would normally have spread out across the regimental front and preceded the regiment into battle. It is not known how they fought on the 3rd but Lt Col Henry Bridges was wounded in the arm and had to be helped from the field. On the 4th they were aligned as an Infantry Regiment on the left flank, and fought into the heart of Corinth. Peter Cozzens in his book on the Battle of Corinth, stated that Colonel Stirman planted the regimental flag in front of the Tishomingo Hotel which was past General Rosecran's headquarters. If this happened Stirman's unit had almost won the battle. Lack of ammunition and men soon caused Stirman to retreat. The next day, the regiment was the 4th unit to cross the Hatchie Bridge in Tennessee. Suddenly a Union blocking force opened up and cannon and rifle fire covered the area. The regiment reversed and raced across the bridge to assume firing positions. Along with the 6th Texas Cavalry Regiment (dismounted) they formed the base for a Confederate blocking force. Several units of Van Dorn's command had been lost, and many of Stirman's men had been killed or captured, but the regiment was a great factor in saving the day.
