  • Artillery Circular, March 1864

    Some very interesting information just prior to the Wilderness. Especially note the new type of canister.



    O.R.-- SERIES I--VOLUME XXXIII [S# 60]

    UNION CORRESPONDENCE, ORDERS, AND RETURNS RELATING TO OPERATIONS IN NORTH CAROLINA, VIRGINIA, WEST VIRGINIA, MARYLAND, AND PENNSYLVANIA, FROM JANUARY 1 TO APRIL 30, 1864.--#16

    [CIRCULAR.] ARTILLERY HDQRS., ARMY OF THE POTOMAC,

    March 14, 1864.

    I. You will at once take the necessary steps to put your brigade in condition to take the field, and for this purpose direct requisition for the necessary number of horses and other materials to be made out.

    II. Should you consider it advisable, the number of horses in a six-gun battery may be carried up to 116, and for a four-gun battery 88, but the number of spare horses should not be carried beyond the possible wants, as the supplies for the number we have are limited.

    III. The ammunition Should, so far as practicable, be made to conform to the proportions directed in General Orders, No. 5, of 1863, from these headquarters, viz, 12 to 16 solid shot, 12 to 8 shrapnel, 4 shell, 4 canister to each chest for 12-pounders; 25 to 30 shell, 20 to 15 shrapnel, 5 canister to each chest for rifle guns.

    IV. Care should be also taken that both Hotchkiss and Schenkl shell, or Hotchkiss and Schenkl shrapnel, should not be used in the same battery. Where such mixtures have taken place the batteries should exchange with each other and with the train, and reduce so far as possible the kind of ammunition which they do not habitually use.

    There is scarcely any occasion on which the percussion-fuse is not superior to the time-fuse shell. It would be a good rule to use only the percussion. Every effort is now being made to provide a concussion shell for the light 12-pounder to supersede the time-fuse.

    V. When requisitions are hereafter made for one kind of ammunition another kind will not be received until it is ascertained that the Artillery Reserve train cannot furnish it, nor even then, except in very urgent cases, will a different kind of ammunition be received than that asked for.

    VI. By a circular from these headquarters, dated December 17, 1863, paragraph I, you were notified that a supply of new canister for light 12-pounders had been ordered (72 3-ounce balls to the canister), and you were requested to make requisition for it at a rate not to exceed 10 rounds per gun. Will you please state in your report of your train if such canister has been received, and call special attention to it with a view of obtaining a report as to its efficiency in our next battles?

    VII. When proper ground can be found in the vicinity of a corps, a course of target practice should be entered upon, of which careful records should be kept and a copy sent to these headquarters. (See Article XI, page 16,Revised Regulations.) In this practice batteries should use only the kind of ammunition they use in battle. Application must be made to the chief of artillery for permission to practice, stating the day and hour at which it is to commence, in order that notice may be given to the other corps and to prevent alarm.

    VIII. The trains will be immediately inspected, and a report of their condition and that of the ammunition made to the chief of artillery, in order, if there are deficiencies, that steps be taken to supply them.

    The allowance of wagons is as follows: Brigade headquarters, two wagons; brigade medical department, one wagon; brigade transportation of subsistence for sales to officers, one wagon; each four-gun battery, four wagons; each six-gun battery, five wagons; to every twenty-five ammunition wagons, five additional ones for transportation of forage for the teams.

    By command of Brigadier-General Hunt:

    JNO. N. CRAIG,
    Assistant Adjutant-General.

    (To chiefs of corps artillery, artillery reserve, and horse brigades.)

    While I am not an artillery expert, this statement draws out my curiousity:

    "There is scarcely any occasion on which the percussion-fuse is not superior to the time-fuse shell. "

    I am familiar with the time-fuse shell, but have not heard of a "percussion-fuse," which I am assuming is a shell that explods on impact. Can somebody clue me in? How common were these rounds?

      Tad,
      Percussion fuses were very common on rifled ammunition. Throughout the war there were many complaints of the poor quality of the time-fuse (see the OR for after action reports).

          Thank you for the excellent links. I had always been of the false assumption that the majority of Civil War-era shells were time fused and designed to explode above the target. How were concusion and percussion fuses generally deployed for anti-personel uses? Were they aimed directly at the column of troops? Does this mean that the hollywood groundcharge used is so many Civil War films is an accurate representation of field artillery at work?

          My world has been rocked, what can I say? :)

            More interesting information as to the reliability of various projectiles and fuses. These observations were made during the Seige of Petersburg, which would probably be the closest that one could come to a scientific field evaluation of ammunition:

            O.R.--SERIES I--VOLUME XLVI/1 [S# 95]

            JANUARY 1-APRIL 3, 1865.--The Richmond (Virginia) Campaign.
            No. 9.--Reports of Bvt. Brig. Gen. Henry L. Abbot, First Connecticut Heavy Artillery, commanding Siege Train, of operations January 1-March 31.


            HEADQUARTERS SIEGE ARTILLERY,

            Broadway Landing, Va., March 5, 1865.


            GENERAL: In obedience to the circular of July 29, 1864, I have the honor to submit the following report of my operations during the month of February, 1865:

            I was absent on leave of absence until February 27.

            The following table exhibits the amount of firing during the month on these lines: Coehorn mortar, 357; 8-inch siege mortar, 509; 10-inch siege mortar, 103; 30-pounder Parrott, 609; 4-inch gun, 63; 100-pounder Parrott, 1; field guns, 3 rounds; making a total of 1,645 rounds, weighing about 32 tons, or at a rate of about 1.1 tons daily, an amount less than in any preceding month.

            There has been so much discussion of late as to the merits of the different kinds of guns and ammunition now in use in our service that 1 have decided to report upon certain records which I have been accumulating here, remarking that it is possible that future firing may modify the results obtained:

            First, as to endurance. The only failures have been the bursting of a 24-pounder Sawyer (rifled), and the blowing off of the muzzle of a 30-pounder Parrott, caused by the explosion of a shell in the bore. The gun was not destroyed; the face was cut smooth with a cold chisel, and its accuracy seems not impaired. The following table shows the extent of the tests, the record of a few guns showing the largest amount of firing being selected:

            One hundred-pounder Parrott.--No. 11, fired 302 times; No. 13, fired 533 times; No. 15, fired 304 times; No. 20, fired 458 times. All old guns; fired an unknown number of times before coming into my possession.

            Thirty-pounder Parrott.--No. 100, fired 1,210 times; No. 101, fired 1,404 times: No. 121, fired 970 times; No. 255, fired 1,487 times; No. 256, fired 1,472 times; No. 259, fired 1,392 times; apparently uninjured.

            Four and one-half inch ordnance.--No. 41, fired 457 times; No. 89, fired 578 times; No. 96, fired 499 times; No. 97, fired 519 times. All rendered dangerous from not being bouched when made; this is a great defect in these guns which should be removed.

            Eight-inch siege mortars.--No. 20, fired 1,530 times; No. 24, fired 1,614 times; No. 25, fired 1,521 times; No. 26, fired 1,536 times; No. 32, fired 2,015 times; No. 36, fired 2,016 times. Apparently uninjured, the vents, even, not showing much wear.

            Second, as to ammunition. The following tables explain themselves; they include February:



            A Number fired. D Took grooves.

            B Uncertain. E Tumbled.

            C Number tested. F Per cent serviceable.

            These figures are too simple and convincing to require remark, other than to explain that every possible care has been taken to secure accuracy. They are taken from the daily reports of the batteries, where men are specially detailed, under the close supervision of the battery commander, to note the effect of every shot. If any uncertainty exists the shot is entered "uncertain," and is not included in the final ratio. I believe that such records have never before been attempted in actual service, and therefore regard them as extremely valuable.

            I am, general, very respectfully, your obedient servant,

            HENRY L. ABBOT,

            Capt. of Engineers, U.S. Army, Bvt. Brig. Gen. of Vols., Comdg.

              Tad,
              A couple of good books to read about artillery are "GRAPE AND CANISTER, THE STORY OF THE FIELD ARTILLERY OF THE ARMY OF THE POTOMAC" by L. Van Loan Naisawald and "A DIARY OF BATTLE, THE PERSONAL JOURNALS OF COLONEL CHARLES S. WAINWRIGHT".

              About 10 years ago, I was invited to work on the Paulson's 30 pdr parrott mounted on a metal barbette carriage and fire 25 rounds of shell with percussion fuses at an APC at 2000 yards. It was hard work, from greasing the shells and inserting the fuses, to working on the gun but well worth the experience.

                Tad:

                Yes, the common upward ground explosion that one sees in Hollywood films depicting 18th and 19th century combat (Rev War and Civil War, mostly) is false. Rarely did artillery shells explode like that, unless mortars were used, though some were in use in the later-war period of the Civil War.

                Artillery shell and case shot would have exploded in the air above troops or in and amongst the troop formations (air bursts). Artillery solid shot would have hit men like a bowling ball cutting through pins and would tear up the ground as it bounced and careened. The only time I ever saw Hollywood use solid shot correctly was in the movie "The Patriot." It one scene it shows a cannon ball bounce along the ground and take off the leg of a soldier. That was well done. The constant ground explosions in "Gettysburg" and "Gods and Generals" made me, an artillery aficianado, sick to my stomach- though there were some air bursts throughout those films. Canister was shown correctly in the "Pickett's Charge" scene in "Gettysburg," displaying 1st Sgt. Frederick Fuger of Battery A, 4th US Artillery pulling the lanyard on his last serviceable gun, spraying double canister into the faces of the enemy.

                The American Civil War was one of the last wars in which direct fire artillery was used. In other words, during the Civil War, one had to be able to see the enemy to use the artillery against him and the rounds would be coming directly at him (very low trajectory). In later wars, especially in WWI and beyond, field artillery (and the advent of light/medium mortars attached to infantry companies) was an indirect fire weapon, stationed in the rear with a high trajectory that brought the rounds down on the enemy from high above - bringing about the ground explosions that we see all the time in movies.

                Hope this helps.

                  Re: Artillery Circular, March 1864

                  It all depends on what kind of gun you are using and what kind of ammunition it was firing.

                  From everything I can find there was never a percussion fuse devised for smoothbore weapons, due to the nature of the round ammunition and the need for an impact to detonate the fuse. So, smoothbore, shot and shell could be used in two ways, first with a wooden, paper, or bormann fuse as an "arial burst" to rain shrapnel down on advancing troops or those behind fortifications, or without a fuze as a cannister substitute known as rottenshot.

                  Rifled guns is where is gets really interesting. Rifled shot and shell could use paper, wooden, bormann, percussion, and combination fuses. The paper, wooded and bormann would produce an effect similar to that of the smoothbore projectiles. The percussion fuse requires an impact to detonate the charge, thus it would explode when it hit the ground. The combination fure was a fuse that could be used as a normal time fuse, or a percussion. Now the big problem with rifled guns and fuses are many. The nature of a rifled gun requires that the projectile expand into the rifling. This effectively cuts off the communication of flame from the discharge to the fuse, hence the high failure rate of time fuses in rifled guns. They just were not being ignited at discharge. Now for a percussion fuse to work the impact had to be great enough to force the slider back igniting the percussion cap and therefore the shell. A grazing shot would not be able to do this. You would need a direct impact into the ground or a fortification to accomplish the goal. The problem is that generallywith a good shot, the shell would bury itself in the ground and explode in the earth. I have references to this happening at numerous battles that I will find and post. So if the fuses even functioned properly (which was also a big problem) there were numerous issues that had to be delt with.

                  Sooooo, the short answer is yes there were things like "ground explosions", it just depended upon what you were using and how.

                    There wasn't an actualy "percussion" fuse for smoothbore guns, exactly for the reasons you mentioned. There was a fuse called a "concussion fuse" which was developed to be used mostly in smoothbores. It didn't rely on a direct impact upon the fuse to explode the shell, just the shock of hitting an object. To quote www.civilwarartillery.com:
                    the actual mechanics of the fuze system varied according to the manufacturer and inventor. Some systems employed chemical vials which, when shattered upon impact, caused a fire inside the fuze body and transferred to the powder chamber. Other systems relied upon plaster to separate the igniting material from the powder until the plaster shattered upon impact.
                    To comment on the new style of cannister, it was Henry Hunt who suggested the change after the battle of Gettysburg:

                    Originally posted by OR Vol 29, Part 2, p. 391
                    ARTILLERY HDQRS. ARMY OF THE POTOMAC,
                    Camp near Warrenton, October 26, 1863.
                    General W. F. BARRY
                    Inspector of Artillery, U. S. Army:
                    GENERAL: There is much complaint of the inefficiency, at close quarters, of the canister for the light 12-pounder gun, owing to the small number of balls it contains. This effect was made apparent at Gettysburg, and is complained of frequently now that the batteries of these guns in the horse artillery often come in close contact with the enemy’s cavalry and infantry. The present canister shot is so large as to be effective at long ranges, so long that it would be better to use shrapnel.
                    I respectfully request that canister with a smaller ball, say of 2 to 3 ounces—or if of smaller diameter than that of a 2-ounce iron ball, then one of lead—may be furnished at as early a day as practicable, in sufficient quantities to furnish at least the horse artillery with one-half their canister of the new pattern. These canisters would carry from 60 to 80 shots, and would probably be much more effective within 200 yards than the present 7-ounce ball of 28 to the canister.
                    HENRY J. HUNT,
                    Brigadier-General, Chief of Artillery.

                      Re: Artillery Circular, March 1864

                      From what I understand a concussion fuse is sort of a hybrid between a time fuse and a percussion fuse. To quote Gibbon's Artillerist Manual:

                      "A concussion fuze may be defined to be one which, taking fire like an ordinary fuze, when the gun is fire, continues to burn until the striking of the shell, when the shock, by producing some chance in the conditition of the fuze, transmits fire to the charge" (276).

                      I was always under the belief that the concussion fuze never really took on. Something more along the lines of a military odity. According to Abbot's report, of the 43,176 fuses used by the siege artillery around Petersburg, only 41 are of the concussion variety. Additionally, I have seen some late war battery battle reports that indicate that they were still using time fuses for smoothbores, by giving fuze time and occasionally barrel elevation.

                        Percussion rounds were used greatly against fixed fortifications as is shown by the high number of rounds fired during Petersburg. It was interesting to note that those, with the possible exception of the 20 lb Parrots, were not field pieces.

                        What the original post helped us with is answering questions during living histories or reenactments.
