North Carolina soldiers proved their loyalty to the CSA by their blood shed on the battlefields. In recent years, the total deaths have been reduced by about 5 or 6 thousand, but it is still larger than for any other Confederate state.
"One-fifth of the Confederate losses in the Seven Days' battles near Richmond in 1862, one-third at Fredericksburg and Chancellorsville, and one-fourth at Gettysburg were North Carolinians. Of the twenty-seven regiments suffering the highest casualties at Gettysburg, thirteen were from North Carolina; the twentieth-six North Carolina regiment suffered casualties of 86 percent, the highest of all regiments on either side during the war. General William R. Cox's brigade fired the last shots of the Army of Northern Virginia, and at Appomattox one-fifth of those who surrendered with Lee were from North Carolina. In the entire war, 19,673 North Carolinians were killed in battle - more than one-fourth of the total Confederate battle deaths and 20,602 died of disease. North Carolina's total loss in battle and from disease was 40,275, which was greater than any other Confederate state."
