As Bee advanced under a severe fire he placed the Seventh and Eighth Georgia Regiments under the chivalrous Bartow, at about 11 a.m. in a wood of second growth pines, to the right and front of and nearly perpendicular to Evans' line of battle; the Fourth Alabama to the left of them, along a fence, connecting the position of the Georgia regiments with the rectangular copse in which Sloan's South Carolina companies were engaged, and into which he also threw the Second Mississippi. A fierce and destructive conflict now ensued. The fire was withering on both sides, while the enemy swept our short thin lines with their numerous artillery, which, according to their official reports, at this time consisted of at least ten rifled guns and four howitzers. For an hour did these stout-hearted men of the blended commands of Bee, Evans, and Bartow breast an unintermitting battle-storm, animated surely by something more than the ordinary courage of even the bravest men under fire. It must have been indeed the inspiration of the cause and consciousness of the great stake at issue which thus nerved and animated one and all to stand unawed and unshrinking in such extremity. . .

. . . The Fourth Alabama also suffered severely from the deadly fire of the thousands of muskets which they so dauntlessly confronted under the immediate leadership of Bee himself. Its brave colonel (E. J. Jones) was dangerously wounded, and many gallant officers fell, slain or hors de combat. . . .

. . . . It was now that General Johnston impressively and gallantly charged to the front, with the colors of the Fourth Alabama Regiment by his side, all the field officers of the regiment having been previously disabled. Shortly afterwards I placed S. R. Gist, adjutant and inspector general of South Carolina, a volunteer aide of General Bee, in command of this regiment, and who led it again to the front as became its previous behavior, and remained with it for the rest of the day. . . . .

. . . . This part of the day was rich with deeds of individual coolness and dauntless conduct, as well as well-directed embodied resolution and bravery, but fraught with the loss to the service of the country of lives of inestimable preciousness at this juncture. The brave Bee was mortally wounded at the head of the Fourth Alabama and some Mississippians. . . .
