What sources are available on the 19th Mississippi Regiment's role during the Gettysburg campaign? Close examination of the Compiled Service Records fills in a lot of gaps, but I have uncovered only one detailed account of the 19th during this period, from the diary of A. L. Peel. Albert L. Peel writes that he received his commission as adjutant on 22 June 1863. On the previous day he mentions making out the field returns and felt the absence of Pryor, no doubt Private Samuel H. Pryor, who was detailed as the adjutant's clerk. Peel occasionally speaks of his brothers Add and Robert, who must be 5th Sergeant Addison Peel of Company I and Surgeon Robert H. Peel. The CSRs reflect the absence of the captains of company A, C, D and H, and I was not able to identify the captains of companies B and K. Company A must have been led by 1st Lieutenant Charles W. Burrage, who is mentioned by Colonel Nathaniel H. Harris in his official report. Frank R. Gregory, 1st Lieutenant of B, was killed by Private Richard G. Wilson of company K, 12th Mississippi in an altercation during the retreat. Although artillery fire typically accounted for one out of every four Confederates who fell at Gettysburg on the plain between Seminary and Cemetery ridges, the ten recorded wounds among the 19th's soldiers were all caused by gunshot, principally if not entirely inflicted by opposing Federal skirmishers. Overall casualties in the regiment were light; the regiment sustained only 34 or so total casualties. The regiment was fairly strong, with about 30 officers and some 340-360 enlisted men, not including approximately 42 men detailed away in the support services. The regiment also appears very well staffed with NCOs since nearly all the sergeants (First through Fifth) and corporals (First through Fourth) are readily identified in every company. Staff officers present included Colonel Harris and Major Thomas J. Hardin, but the status of Lieutenant Colonel Wood G. Vaughan is a mystery. Vaughan resigned from the regiment on 17 July 1863; whether he accompanied the regiment into Pennsylvania is unclear. Of interest among the ranks, Sergeant Major (appointed 2 May 1863) William P. "Willie" Meaders was the brother of Joseph P. Meaders, then commissary sergeant of the 42nd Mississippi. Seven musicians are identified in the regiment, including drummer Ellis M. Perkins of company E. Private John S. Williams joined company B after transferring from company H of the 17th Mississippi on 30 May 1863. Private Edward A. Williams of company E was captured on 5 July at Cashtown, where, if not a straggler, he may have been assisting the wounded at a field hospital; in any case it seems he passed himself off as an assistant surgeon, as noted in Federal POW records. Like other captured surgeons, he wound up at Fort McHenry and was soon exchanged.
