I have the book and read it; Covered With Glory: The 26th North Carolina Infantry at Gettysburg by Rod Gragg. It was the largest regiment in the Confederate Army with a little over 800 men and officers with the Colonel Henry Burgwyn Jr known as "The Boy Colonel", for he was the youngest Colonel in the Confederate Army.
They were part of Heth's division of Hill's Corps who attacked two regiments from the Iron Brigade on the 1st day. Their charge resulted in suffering 577 casualties but beat off the Federal troops off the field. Colonel Burgwyn Jr was mortally wounded, the colors fell more times than any other regiment North or South in a single battle in the entire war. In one company, all but one man were casualties.
Brigadier General Pettigrew galloped and shouted to them that they had covered themselves with glory!
The second day of the battle they rested but took part of Pickett's Charge on the 3rd day in Pettigrew's Division. They were among the few who made it over the stonewall penetrating further than any other Confederate regiments. After the charge failed, they withdrew back to the Confederate lines and at the roll call there were only 80 men left when the battle of Gettysburg was over.
