From the War Department tablet for Field’s Brigade number 349 on the Antietam battlefield:
Field’s Brigade left Harpers Ferry at 7:30 A.M. of September 17, reached this point about 3 P.M. and was put in position to guard the approaches to the field by Snavely’s Ford and the lower Antietam.
The Brigade was not actively engaged, and recrossed the Potomac early on the morning of September 19.
Commanded by Captain T. Edwin Betts.
|March 5||Brigadier General Henry Heth took command of the brigade and Colonel Brockenbrough returned to command of the regiment.|
|May 2||Assigned to Field’s-Walker’s Brigade, Heth’s Division, 3rd Corps, Army of Northern Virginia. General Heth was promoted to division command and Colonel Brockenbrough once again took command of the brigade as senior colonel.|
Lieutenant Colonel Cox was wounded, losing his eye. He would be absent through August recuperating. Captain Thomas E. Betts took command of the regiment.
At Gettysburg Captain Thomas E. Betts commanded the regiment while Colonel Brockenbrough commanded the brigade as senior colonel. The brigade was last in the line of march of Heth’s Division and did not arrive in time for the morning actions. In the afternoon fighting it was not particularly aggressive, losing only a hundred casualties in the otherwise fierce fighting on Seminary Ridge. Colonel Brockenbrough’s brother was killed at this time, which probably affected his effectiveness.
On the third day during Pickett’s Charge the brigade, under the temporary command of Colonel Mayo of the 47th Virginia Infantry, was placed on the extreme left flank of the assault. It was exposed to intense fire from both front and flank. They collapsed and ran to the rear, the first brigade in the attack to do so. Captain Betts was wounded and captured, and Captain R. B. Davis took command of the regiment.
From the monument to Brockenbrough’s Brigade on the Gettysburg battlefield:
July 1. Crossed the Run at 2 P.M. between Chambersburg Pike and Reynolds Woods. Engaged Union forces on McPherson ridge and with other troops on left drove them back to next ridge capturing two flags and many prisoners with some sharpshooters in the barn. Soon afterwards the Brigade was relieved by Pender’s Division.
July 2. Lay in the woods west of the Run. In the evening took position near here.
July 3. In Longstreet’s assault this Brigade was on the left flank of the column and as it approached the Union position was exposed to a severe fire of musketry on the left flank and artillery and musketry in front. It pushed beyond the Emmitsburg Road but was met by a heavy front and flank fire from the Union lines north of the Bryan Barn and compelled to fall back.
July 4. After night withdrew and began the march to Hagerstown.
