June 28, 1878, marked the centennial of the battle of Monmouth, and the anniversary did not pass without commemoration in the town of Freehold, New Jersey, the original location of Monmouth Courthouse. Local newspapers reported that over 20,000 people attended the various ceremonies, orations, and performances that were held, with local and state politicians, and veterans of the War of 1812, Mexican-American War, and the recent Civil War in attendance. George B. McClellan, former commanding general of the Union Armies and the Army of the Potomac, then serving as New Jersey’s governor, reviewed state troops and participated in the cornerstone laying of the Monmouth Battle Monument. The ceremony was the center of the commemorations that day. Although the 94-foot-tall monument crowned by a statue of “Colombia Triumphant,” would not be completed and dedicated until November 1884, those who attended the centennial events understood the significance of what it would represent. After all, it had only been thirteen years since the end of the previous war—one that was fought to save the republic that those who had bled at Monmouth fought themselves to establish. The symbolism was not lost on Enoch L. Cowart, a veteran of the 14th New Jersey Volunteers, which was trained at Camp Vredenburgh around the old battlefield. On July 4, 1878, an original poem he had written, “Centennial of the Battle of Monmouth,” was published in the Monmouth Democrat. Here is that poem below:
Emerging Revolutionary War welcomes back guest historian Karl G. Elsea
If you want to know the process of how field guns were fired in a battle such as Trenton or Monmouth, watching the National Park Service or re-enactors fire a cannon, you will only get part of the story. Important parts of the procedure are almost always missing. Here is a more complete presentation of the process; and, how leveling, pointing (aiming), and elevating a field gun were performed.
Major William Congreve said it best in his instructional training works at the Royal Military Repository in the late 1700’s: “It is of the utmost Consequence to the Service to fire so as to do Execution, for Shot flying over the Enemies head only hardens them and discourages your own Troops.” “Rounds must never be fired with-out pointing the Gun carefully each time and paying great attention to the Elevation.”[i]
After the commands, unlimber piece (un-attach the gun from the limber), take off apron (remove the vent cover), take out tompion (remove the “plug” at the muzzle of the gun), the gunners would perform the following activity with-out a specific command. This was a critical function and is not usually shown when firing a gun. It was to level the piece. As stated in their training, “and which ever Wheel stands too high, the Earth must be loosened in the rear, and the Gun drawn gently back until the Bubble rest in the Center of the Tube.”[ii] The science was simple, the trunnions on the barrel must be level or the barrel will move in a non-vertical plane and thus be off target. Leveling the gun was of great importance. The Artillerist’s Companion 1778 states it was an artillerist’s function, “Quadrating a piece [barrel] mounted, is to see whether it be directly placed, and equally poised in the carriage, which may be found by a gunner’s instrument called a level or perpendicular.”[iii]
The following picture shows what was called the Gunner’s level or the Spirit Level. It was the quintessential instrument carried by gunners to level the gun. In a cylinder in the middle of the gunner’s level was a vial and when the trunnions are level the bubble in the vial will be in the middle. At that point the gun was leveled.
The next activity was sometimes required to point the gun and it also required the Gunner’s Level. The level could be used to place a noticeable mark indicating the top of the base ring and the top of the muzzle ring. These two marks constitute what was called the “centre” [center] line of the cannon. The activity of marking the “centre” line was performed immediately after leveling the cannon unless the points or the line were already marked on the cannon. This line on the barrel was called the “gun metal line.” On many of the guns of the period the metal line marks were discretely engraved into the design on the barrel. For example, on this patriot cast Byers’ gun the base ring line, touch hole, and liberty pole mark one end of the “gun metal line.”
After these tasks (leveling and marking) were complete the gun was ready for pointing (aiming). With regards to the Patriot’s drill, there was a distinct difference between the primary source drills of William Stevens and Louis de Tousard. Stevens records that “Take Aim” happens after the command “Prime.”[iv] In Tousard’s drill “Take Aim” takes place before “Prime.”[v] There was a reason for these differences, and it depended on how the gun was primed. The use of a priming tube, whether tin, reed, or quill, could potentially block the sighting line. Tousard’s drill avoided this problem by sighting before the priming tube was inserted. It should be noted the centre line passed over the touch hole. It was noteworthy that the British drill specifically mentions pointing before the tube was inserted into the touch hole. The British drills for a six-pounder stated, “The man who serves the Vent … not put the tube in until the Gun is pointed.”[vi] With regards to Steven’s drill, the priming likely consisted of using powder to touch off the charge, thus the “take aim” command could take place after priming. Using powder only to prime did not block the sighting line. Tousard’s drill assumed tubes were used in priming. British and Patriots used tubes as the preferred manor in priming field guns.
Last came the task of elevating the gun barrel. The need for proper elevation of the barrel was demonstrated by noting the psychological impact of cannon fire as shown in the following contemporary quote, “it having been often proved that Soldiers have been more alarmed and put in confusion, by seeing Shot hopping to them, than by having double the Number of their Comrades killed by their sides without seeing it.”[vii] That quote showed the importance for shot to land and bounce somewhat in front of the soldiers. Elevation was adjusted to accomplish that task.
For elevation the gunners would know their individual piece and the characteristics concerning how the various types of shot with varying powder charges would fall. The Officers would likely have some recordation measuring the needed elevation for the distance to first graze. First graze was the range at which the shot would first touch the ground. That recordation would allow the gunners to know what elevation to use for their barrel.
The gunners would also know what the dispart (half the difference between the diameter of the base ring and muzzle ring) was for their individual gun. Dispart was the key to understanding that aiming the gun on the centre line automatically elevates the barrel. Dispart could be quickly measured in the field by placing the vent pick into the touch hole until it reached the bottom, and then subtract that measurement taken at the muzzle from the bottom of the tube to the top of the muzzle ring. As noted above, when the cannon was aimed using the centre line (“gun metal line”) then the resulting cannon ball strike on level ground was called the “Common range.” Common range was different from “point blank range” which was the distance when a cannon ball first touches ground when fired from a level barrel on level ground.
There was an exception to aiming and elevating the gun. The exception was if a gun were to be overrun. British training materials stated, “Case Shot may be fired as quick as the Dragropemen can draw the Gun up to its proper Position in the Interval again, which will allow the Non Commissioned Officer a sufficient time to direct the Gun nearly to the Center of the Enemies Battalion and give a pretty good guess at the Elevation.”[viii]

Both titles are scheduled for a release later this year. Stay tuned for updates!
Bob Drury and Tom Clavin have spent years writing books, both individually and as a team. Between the two of them, they have explored topics ranging from baseball and golf to the old west and America’s 20th century wars. With Valley Forge (Simon & Schuster, 2018), Clavin and Drury have turned to the American Revolution. The result is another successful collaboration. (I’m biased as I have enjoyed several of their earlier books.)
Valley Forge tackles the Philadelphia Campaign, the winter encampment at Valley Forge (and elsewhere in truth), and the Continental Army’s emergence as a quality army capable of fighting the British on their own terms, which it demonstrated at Monmouth. The focus is on Washington and the main army with him. The reader sees both of them grow as Washington defeats political attempts to undermine his leadership and struggles to hold the army together in the face of harsh conditions and insufficient support from the rebelling states, Continental Congress, and local farmers. Meanwhile, the Army develops into a core of hard-bitten professionals suitably trained in European methods specifically adjusted for their circumstances. After undergoing Steuben’s training program, it had the military skills needed to match its fighting spirit. By and large, it marked a turning point in the war. Thus, at the end, the authors argue, “For those who survived, not least their inspired and inspiring commander in chief, the hardships they overcame had not so much transformed their innate character as revealed it.”[i]Continue reading “Book Review: Bob Drury & Tom Clavin, Valley Forge, Kindle ed., (New York: Simon & Schuster, 2018).”→
Emerging Revolutionary War is honored to welcome guest historian Scott H. Harris, Director of the James Monroe Museum.
It is one of the great exploits of the American Revolution. On the night of December 25, 1776, General George Washington led the Continental Army across the icy Delaware River to attack a Hessian garrison at Trenton, New Jersey. Young Lieutenant James Monroe held the flag behind Washington as they were rowed across the freezing river (standing up).
