Friends of Padre Steve’s World,

Another in my series of rather geek-like articles on Civil War artillery.

Have a great day.

The American Civil War was a transitional time for artillery technology, organization and tactics. The organization of the artillery service of the Army of the Potomac remained as it was up until the Overland or Wilderness Campaign, although “Corps brigades were increased to eight or nine batteries.” However, “having created a sound artillery organization and proven it at Gettysburg, the Union would have little immediate use for it” [1] as the changing conditions of war in the Wilderness changed how Grant and Meade organized the artillery.

The Artillery Reserve, a throwback to Napoleonic times, which had along with the rest of the Union artillery at Gettysburg performed so brilliantly in a defensive stand with wide open fields of interlocking fire would never again have such an opportunity to wreak destruction on advancing Confederate infantry in the open. Instead it was forced into the offensive in terrain that was seldom conducive to employing massed numbers of guns. During the campaign the Artillery Reserve consisted of “two field artillery brigades of twelve batteries each, one heavy brigade, which was largely employed as a guard and construction unit, and two brigades of horse artillery, which were on duty with Major Phil Sheridan’s cavalry corps.” [2] By the time of the Wilderness Campaign the size of the Army of the Potomac’s artillery numbered 274 cannon. [3] In terms of artillery types Hunt had 154 rifled guns and 120 Napoleons in the organic components of his army, of the rifled guns the majority were the 3” Ordnance rifles as Hunt had sent most of his Parrot batteries away due to their tendency to burst and their unpopularity with their gun crews. [4] The artillery was bolster with a battery of eight 24 pound brass Coehorn mortars. These were light weapons which weighed only 164 pounds and could be carried by two men. They “were fired at an angle of 45 degrees which permitted them to hurl a shell in a very high arch to a distance of 1,200 yards at full charge.” [5]

The campaigns of 1864 forced Union army commanders to change how they employed their artillery. This came first during the Wilderness campaign where the heavily wooded terrain, poor visibility, and an enemy dug in behind earthen walls and abattis limited the artillery’s effectiveness. The fighting between enemies that could barely see what they were shooting at resulted in close range firefights between infantry with few artillery pieces in direct support. When engaged, the artillery of both sides dealt death at close range in support of infantry, on the defensive the guns were dug in to protect them and their crews from the close range fire of enemy artillery and infantry. The heavy brush limited the ability of the artillery to move off the main roads as one artilleryman noted that they could do nothing “because no horses could have pulled a gun through the brush in which the infantry were fighting.” [6] One officer described the conditions of the Wilderness as “a wrestle as blind as midnight, a gloom that made manoeuvers impractical, a jungle where regiments stumbled on each other and the enemy by turns, firing sometimes into their own ranks, and guided only by the crackling of bushes or the cheers and cries that rose from the depths around.” [7]

With his guns finding little employment “Grant order that the Artillery Reserve be returned to Washington.” [8] To achieve the reduction in the number of guns without undoing his organization, Hunt recommended that the batteries be reduced from six guns to four. This was done but Hunt lost his Artillery Reserve as Meade had those reduced batteries reassigned to each of the infantry corps and the Reserve’s commander, Colonel Henry Burton, “appointed Inspector of Artillery.” [9] However, “most of the pieces ordered away were returned for the siege of Petersburg.” [10] Grant wrote:

“The Wilderness and Spotsylvania battles convinced me that we had more artillery than could ever be brought to action at any one time. It occupied much of the road marching, and taxed the trains in bringing up forage. Artillery is very useful when it can be brought into action, but it is a burdensome where it cannot be used. Before leaving Spotsylvania, therefore, I sent back to the defenses of Washington over one hundred pieces of artillery, with horses and caissons… and still left us with more artillery than could be advantageously used.” [11]

During the Wilderness Campaign the Confederate artillery suffered under similar conditions to Grant’s armies. Porter Alexander noted that when his artillery arrived that Lee, “directed me to send back all the artillery with our column to Parker’s Store, as there was no possibility of using it in the woods where we would be fighting, & it would be in the way.” [12] Where they were employed on the defensive the Confederate guns gave good account of themselves. Where they were not deployed attacking Union forces found their task easier, as when Winfield Scott Hancock’s massed attack at Spotsylvania succeeded, However, when the Confederates were able to deploy their artillery Union losses could be dreadful. This was the case at Cold Harbor where Grant ordered a frontal assault on well prepared Confederate defenders who had their artillery in positions where it had advancing Union forces in a crossfire.

The siege of Petersburg changed the way artillery was employed in the east yet again. “After Petersburg, field tactics were scarcely relevant, although concentrations of fire remained essential.” [13]

Many commentators after the war decried the effectiveness of the artillery by claiming that less than ten percent of casualties were caused by it. As J.B.A. Bailey notes, “This figure seems highly improbable, since the wound inflicted by a canister ball, which was the artillery’s most lethal projectile, would have been impossible to distinguish from that inflicted by a musket ball.” [14] However, even more important than the number of casualties inflicted on the enemy, but it was the shock power and deterrent effect that artillery had on the enemy, especially on the defensive. Colonel Jennings Wise, who chronicled the history of Lee’s artillery wrote:

“We often hear the sneering criticism that at such and such a battle but 1 or 2 per cent of the enemy’s loss was due to fire of the artillery. Any such test entirely erroneous. Not only do the guns exert a tremendous moral effect in support of their infantry, and adverse to the enemy, but they do far more. They often preclude heavy damage from the enemy by preventing him from essaying an assault against the positions the guns occupy. Then, again, by forcing them to seek cover, they eliminate their antagonisms to that extent… Let us hear no more of artillery efficiency as measured by the number of its victims.” [15]

Descriptions of the effect of the Union artillery on Pickett’s charge at Gettysburg bear this out. “The Confederate losses mounted at an alarming rate. The psychological impact of artillery casualties was great, for the big guns not only killed but mangled bodies, tore them apart, or disintegrated them.” [16] A survivor wrote his wife days later: “If the crash of worlds and all things combustible had been coming in collision with each other, it could not have surpassed it seemingly. To me it was like the “Magazine of Vengeance” blown up.” [17] A soldier of Kemper’s brigade recalled that “The atmosphere was rent and broken by the rust and crash of projectiles…The sun, but a few minutes before so brilliant, was now darkened. Through this smoky darkness came the missiles of death…the scene beggars description…Many a fellow thought his time had come…Great big, stout hearted men prayed, loudly too….” [18] Colonel Joseph Mayo of the 3rd Virginia regiment was heavily hit. One of its survivors wrote: “when the line rose up to charge…it appeared that as many were left dead and wounded as got up.” [19]

“This Fiery Line” The Triumph of Lieutenant Colonel Freeman McGilvery and the Artillery at Plum Run, Gettysburg July 2nd 1863

12 pound napoleon

Artillery at the Trostle Farm

The disaster that engulfed Sickles’ III Corps now threatened the Federal center. Meade and Hancock rushed reinforcements in the form of V Corps and much of II Corps. The tip of the Sickle’s salient at Sherfy’s Peach Orchard manned by Graham’s brigade of David Birney’s division was overwhelmed and retreated in disorder. Once “the angle had been breached, the lines connecting to it on the east and north were doomed.” [1] This exposed the left of Humphery’s division and it too was forced to retreat under heavy pressure sustaining heavy casualties. The final collapse of Humphrey’s division a large gap opened in the Federal lines between the elements of V Corps fighting along Devil’s Den and Little Round Top and II Corps along the central portion of Cemetery Ridge.

When Meade realized the seriousness of the situation he gave Sickles’ free reign to call for reinforcements from Harry Hunt’s Artillery Reserve as III Corps had only batteries organic to it. Those five batteries were in the think of the fighting providing invaluable support to Sickles’ hard pressed and outnumbered corps. Firing canister they cut swaths of death and destruction through the massed ranks of wildly cheering Confederates of Kershaw and Semmes and Barkdale’s brigades of McLaws’ division.

The Confederates believed that they had cut the Union line in half and advanced through the Peach Orchard and across the Wheat Field toward Cemetery Ridge.

mcgilvery

Among the artillery called into action was the First Volunteer Brigade under the command of Lieutenant Colonel Freeman McGilvery. McGilvery, a Maine native was a former sea captain who had organized and commanded the 6th Maine Battery at the beginning of the war. He commanded it with distinction in a number of engagements. Promoted to Major in early 1863 he assumed command of the Brigade and fought at Chancellorsville and was promoted to Lieutenant Colonel in June as the Army of the Potomac pursued Lee’s Army.

McGilvery rode into the maelstrom of the retreating III Corps soldiers and broken guns. His horse was hit four times but he remained unwounded despite “exposing himself to enemy missiles on all parts of the field from Cemetery Ridge to the Peach Orchard.” [2] He noted that there was no infantry anywhere that could plug the gap and acted instantly on his own authority to make a decision that likely saved the Union line. In the confusion of III Corps disintegration three of his batteries had withdrawn leaving Captain John Bigelow’s 9th Massachusetts battery alone at the Trostle farm telling them they must “hold at all hazards.” [3] Bigelow later explained that McGilvery said that “for 4 or 500 yards in my rear there were no Union troops.” He was then instructed by McGilvery “For heavens [sic] sake hold that line…until he could get some other batteries in position…” [4] In another account Bigelow recorded “Captain Bigelow…there is not an infantryman back of you along the whole line which Sickles moved out; you must remain where you are and hold your position at all hazards, and sacrifice your battery if need be, until at least I can find some batteries to put in position and cover you.” [5]

The order could have been considered suicidal; the 21st Mississippi was nearly upon them and they were but one battery and barely one hundred troops. Bigelow did not hesitate to obey; he brought his guns into line at the Trostle house “facing one section slightly to the southwest and the other two sections directly into the path of the oncoming Confederates.” [6]

Bigelow’s artillerymen fought like demons he described the effect of his fire on Kershaw’s South Carolinians “the Battery immediately enfiladed them with a rapid fire of canister, which tore through their ranks and sprinkled the field with their dead and wound, until they disappeared in the woods on our left, apparently a mob.” [7] They poured a merciless stream of fire into the advancing Confederates until “they had exhausted their supply of canister and the enemy began to close in on his flanks.” [8] A German born gunner noted “we mowed them down like grass, but they were thick and rushed up.” [9] A hand to hand fight ensued among the guns but the Massachusetts men escaped losing 28 of its 104 men engaged,[10] the brave commander Bigelow was wounded and nearly captured but one of his men helped him to the rear.

Their sacrifice was not in vain. They bought McGilvery an additional 30 minutes to set up a line of guns along Plum Run. Hunt praised the battery “As the battery had sacrificed itself for the safety of the line, its work is specially noticed as typical of the service that artillery is not infrequently called to render, and did render in other instances at Gettysburg besides this one.”[11]

Bigelow’s Map of the Action at Trostle Farm

Barksdale’s brigade did not pause and continued in their relentless advance towards Cemetery Ridge, sweeping Union stragglers up as they moved forward led by their irrepressible Colonel. Before them was McGilvery’s new line, hastily cobbled together from any batteries and guns that he could find. Initially composed of 13-15 guns of four different batteries he was joined by two more batteries giving him about 25 guns in all. Subjected to intense Confederate artillery fire and infantry attacks his guns held on even as their numbers were reduced until only six guns remained operational. “Expertly directed by McGilvery a few stouthearted artillerymen continued to blaze away and keep the low bushes in front of them clear of lurking sharpshooters. Although they had no infantry supports, they somehow managed to create the illusion that the woods to their rear were filled with them, and they closed the breach until the Union high command could bring up reinforcements.” [12]

The reinforcements came in the form of Colonel George Willard’s “Harper’s Ferry” Brigade which was looking for revenge and redemption. This unit hit Barksdale’s now disorganized force which had reached its cumulating point hard. Willard was killed and Barksdale mortally wounded and captured in the violent clash which spelled the end of one of the greatest threats to the Union line of the entire battle. Philip Tucker in his book Barksdale’s Charge: The True High Tide of the Confederacy at Gettysburg, July 2, 1863 refers to Barksdale’s charge as the real “high water mark of the Confederacy.”

Plum Run Line

However it was McGilvery who recognized the emergency confronting the line and on his own took responsibility to rectify the situation. He courageously risked “his career in assuming authority beyond his rank” [13] and without his quick action, courage under fire and expert direction of his guns Barksdale’s men might have completed the breakthrough that could have won the battle for General Lee despite all of the mistakes committed by his senior leaders that day.

It was another example of an officer who had the trust of his superiors who did the right thing at the right time. It is an example of an officer used the principles of what we today call Mission Command to decisively impact a battle. McGilvery rose higher in the Federal service and was promoted to Colonel and command of the artillery of X Corps. He was slightly wounded in a finger at the battle of Deep Bottom in August 1864. The wound did not heal properly so surgeon’s decided to amputate the finger. However they administered a lethal dose of chloroform anesthesia and he died on September 9th, the Union losing one its finest artillerymen. He was buried in his native Maine and the State legislature designated the first Saturday in September as Colonel Freeman McGilvery Day in 2001.
