CONFEDERATE CORRESPONDENCE, ETC.--#10
CHARLESTON, September 25, 1863.
Lieut. Col. J. R. WADDY,
Chief of Ordnance Department:
COLONEL: On the 24th instant I inspected the ordnance and ordnance stores at the following batteries: Haskell, Tatom, Ryan, and Redoubt No. 1, eastern lines, all under the command of Maj. Edward Manigault, and have the honor to submit the following report:
[excerpt]
I beg leave to entail upon you the trouble of reading the following remarks in reference to the alteration of guns from smooth to rifled, the banding of guns, weight of projectiles, the wear and tear of carriages, which is deemed important to the economy of ordnance, and of your consideration. The conclusions arrived at are based on the evidence of facts and experience in the field, and will be placed before you as concisely as a clear expression will admit.
First. Some manufacturers of ordnance deny the fact that a gun is weakened by rifling, and attribute their frequent bursting to the heavier projectiles used. While there is some truth as regards weight of projectiles, it is a fact that the fractures in rifled guns follow the edge of the groove exactly as ice and granite fracture in lines cut upon the surface. It is known that acute re-entering angles upon the surface of guns are the usual lines of rupture, hence the present external form of guns without moldings. From these facts, no rifled guns should have acute or sharp-edged grooves, but a flattened curve thus /¯¯¯¯¯¯\ as a Parrott, which, though it does not remedy the injury from rifling, has been proved to be the least injurious form.
Second. Banded guns, facts and experience prove, to be weaker at the breech than at the re-enforce, as of four which I have examined on the front of our defenses, all have fractured square at the vent, throwing the breech to the rear. If the breech is strengthened, explosions would not be so frequent. It would be economical, therefore, to use the wrought-iron shackles of Captain Brooke, although the expense of banding would be double. Some suppose this arrangement weakens the trunnion, but it is a mistake. A trunnion that is not previously fractured is never torn off by the recoil, which shock it is only subjected to, and to which the additional weight of the shackle would add but little momentum. An improvement on this plan would be to cast or turn off a hemispherical breech, over which fit a wrought-iron band accurately adjusted, and over this the trunnion shackle, or any other method that would secure the breech in a wrought-iron shell in close or firm contact with the cast iron.
Third. We are certainly in error as regards weight of elongated projectiles, which requires immediate correction for effective service, as well as on the score of economy. We must have some safe, fixed limit determined for the weight of shot, beyond which weight it should be made penal to serve, for we cannot afford experiments in the field, excepting at the cost of dismantling our works, and this it would be more judicious, as well as economical, to leave to the prowess of the enemy.

HEADQUARTERS ORDNANCE DEPARTMENT,
Charleston, October 14, 1863.
Respectfully forwarded to department headquarters.
The defects referred to in the Blakely projectiles have been before reported upon, and I am informed by the commanding officer of the arsenal that they are the same projectiles sent from England with the guns. Some of this officer's ideas on rifling guns are good. Other suggestions are approved.
J. R. WADDY,
Chief of Ordnance.

As far as Parrotts being rifled or not -- this may support the facts that the Parrotts were rifled.

CONFEDERATE CORRESPONDENCE, ETC.--#1
RICHMOND, VA., April 29, 1861.
Col. R. S. GARNETT,
Adjutant-General, Virginia Army, Richmond, Va.:
SIR: I have the honor to report that there are three light artillery batteries now together at the artillery barracks, Baptist Seminary, viz: Randolph's (of six pieces, called the Howitzer Battery), Cabell's (four pieces of light artillery), and Latham's (four pieces of light artillery). Two pieces will be added to Randolph's battery, he having two hundred and twenty-five drilled men in his company. I propose that these two pieces should be Parrotts rifled cannon, as being more nearly the weight of Randolph's howitzers, which are of the Dahlgren pattern.
I have to request that the battery of rifled cannon (Parrotts), now in charge of Captain Walker, and some forty men, not mustered into service, and now at Fredericksburg, Va., be ordered to the artillery barracks near this place, and, after turning over their cannon and implements, that Captain Walker's company (if it can be made up to its proper complement) be received into the artillery service and drilled, so as to be ready for service with any battery that may be prepared for it.
