Big Brass Cannons – 24-pdr Field Howitzers

Prior to the Civil War, field artillery retained the type-classification and employment doctrine from the early 19th-century, leaning heavily on the European Napoleonic experience.  While emerging technologies would shift both the classifications and the doctrine during the Civil War, even in 1866, the Army stubbornly clung to the old ways.   Perhaps the best example of this adherence to classification and doctrine was the 24-pdr Field Howitzer.   The weapon class traced back to colonial and Revolutionary War period heavy field ordnance, but had evolved considerably with time.

In that age, ordnance designers built howitzers to loft explosive shells, at higher angles than the guns, onto targets at longer ranges than mortars.  During the Revolutionary War, the 8-inch caliber was popular, but I have found howitzers ranging from 4.62-inch and 5.5-inch calibers from that era.  These were somewhat stumpy bronze pieces.  Contemporary sources credit these weapons with effective ranges of around 750 to 800 yards, and maximum range out to 1300 yards.  (Apologies for the old 35mm photo)

During the early years of the United States, the Army made a switch to iron field pieces.  Initial developments continued the short, stumpy appearance.  However, with iron generally heavier than bronze, the smaller 24-pdr or 5.82-inch caliber was standardized for field pieces (the 8-inch caliber continued for siege and garrison weapons, though).  Unfortunately, the documentation regarding these early American 24-pdr Field Howitzers is almost non-existent.  About the only “facts” we know is from examination of a handful of examples surviving today.  Castillo de San Marcos, in St. Augustine Florida has three such weapons in its collection.  (Again apologies for the old 35mm photo, it has been some time since my last visit to the fort)

The second piece from the camera conforms to the “pattern of 1819” forms.  But the howitzer closet to the camera, and the third from the end are of unknown patterns.  The pattern of 1819 weapon is about 33 inches long overall, with a 29 inch bore – or roughly five calibers.  No shot tables exist, but likely these pieces inherited the short ranges of their predecessors.  In order to extend range, the most efficient option was to simply lengthen the bore.

Records indicate the Army experimented with several iron 24-pdr field howitzers from 1834 to 1841.  Columbia Foundry in the District of Columbia, Cyrus Alger of Boston, and West Point Foundry in New York delivered at least seventeen examples.  The Army tested several weapons imported from Europe.  Regardless, iron was found, as it was for the smaller 6-pdr field guns, unsuitable at that time.  Alger and N.P. Ames Foundries produced 56 bronze 24-pdr Field Howitzers from 1836 to 1838 to fill the Army’s requirements instead.  Unfortunately none of these are cataloged survivors.  The only particular known for these weapons is the weights of a select few – averaging 1320 pounds.  Quite likely, these conformed to established bronze patterns in use at the time, with breach and chase rings.

In fact, other than the handful of iron pieces mentioned above, the only field howitzers of the 24-pdr caliber surviving today are bronze types produced from 1841 to 1863, conforming to standards established in 1841 for exterior shape.  Of 69 tallied as delivered by Cyrus Alger and N.P. Ames, nearly two-thirds survive today.  Contemporary regulations listed a Model 1844, but with the production starting in 1841, the earlier date for the pattern is consistent.  I will, then, consider these Model 1841 24-pdr Field Howitzers.  From the standpoint of doctrine, the 24-pdr howitzers paired with the 12-pdr Field Guns, if employed to mixed batteries.  Artillerists planned to employ these howitzers supporting the main infantry line and the flying batteries, lobbing shells to break up enemy infantry and artillery covered by terrain or fortifications.

Model 1841 24-pdr Field Howitzer "No 1"

Of these surviving Model 1841s, numbers 1 and 2 from the Alger production batch stand side by side at Shiloh National Military park, representing Battery D, 1st Illinois Light Artillery (McAllister’s Battery).  The monument stands at the battery’s position in the morning fighting on April 6, 1862.  As part of McClernand’s 1st Division, Army of the Tennessee, the battery went into action with four 24-pdr howitzers near Review Field.  McAllister’s Battery was driven back during the afternoon eventually finding a place in line near Pittsburg Landing, losing two pieces in the process.  In the second day’s fighting, those two remaining 24-pdrs were used to support Marsh’s Brigade of McClernand’s Division.

The summary of that battery’s activities at Shiloh brings up the logical question with regard to handiness of the 24-pdrs in action.  Compare the 24-pdr with the figures for the 12-pdr Field Howitzer, 12-pdr Light Field gun Model 1857 (Napoleon), and the 32-pdr Field Howitzer below:

24-pdr How Table

(Select image to zoom in) (See comments)

Just looking at the raw numbers, the 24-pdr Howitzer, while 100 pounds heavier than the Napoleon, could throw a projectile twice the size to the same range.  Arguably, for the fighting in wood thickets at Shiloh, the 12-pdr Field Howitzers were handier and possessed sufficient range for the action.  But certainly in open fields, one would prefer either the Napoleon or 24-pdr for range.  But the 32-pdr, even given increases in range and throw weight, was much too heavy.

On paper, the only disadvantage of the 24-pdr compared to the Napoleon was the 100 extra pounds of the gun tube.  But that is certainly not all the story.  The Napoleon used a slightly lighter carriage, further splitting the weight difference.  That seemingly small difference in weight required an eight-horse team for the 24-pdr, over the six-horse team of the Napoleon.  Lastly, consider the ready ammunition.  A standard 12-pdr Napoleon chest included 12 shot, 12 case, 4 shells, and 4 canister for a total of 32 rounds.  But the 24-pdr chest contained 12 shells, 8 case, and 3 canister – a total of nine less than the smaller gun.  Further amplifying the weight issue, a chest of 12-pdr ammunition weighed 484 pounds compared to 565 pounds for the 24-pdr.   Thus any commander was faced with a logistic problem – in order to keep the 24-pdr on line with the 12-pdr over a fixed period of time, he had to allocate more horseflesh to hauling more ammunition chests, in addition to animals with the guns.   Yes, in the real tactical world, seldom is an item’s weight a specification overlooked without consequence.

That explanation for the 24-pdr Field Howitzer’s limited use aside, a fair number of the pieces stand on the battlefields and town squares today as reminders of the Civil War.  And, at least the Federal version, is easy to identify from a distance.  The handles over the trunnions are the first indicator.

The piece above represents Battery F, 2nd Illinois Lt. Artillery (Powell’s Battery), on the defensive line near Pittsburg Landing,  close to the Shiloh visitor center.

The handles were somewhat the continued design practice from those old 18th century guns.  Functionally the adornment offered a purchase for ropes while the tube was mounted.  But as the metallurgical arts progressed, designers realized such features offered stress points and impediments to clean casting.  Early production 24-pdr Howitzers used handles with the half octagon profile shape seen above.  Alger models used a rectangular “pad” where the handle joined the gun tube.   Ames used an octagon shaped pad.  However, later production, in 1862-63, featured completely round handles.

Another visual indicator for the 24-pdr Field Howitzer is the recessed area over the chamber.

Alger 24-pdr FH, No. 2

Alger 24-pdr FH, No. 2

Going back to McAllister’s Battery, this time looking at registry number 2, the line of the recessed area is apparent just in front of the vent.  Since this is a howitzer, and by definition uses a sub-caliber chamber (in this case 4.62 inch diameter), there is less stress on the breech.  As such, the designers were able to save a little weight by removing metal from the casting form over the breech.  The difference in diameter is only about a half inch, but enough to change the weapon’s profile.

Chamber?  Yes indeed:

Note the lip of the chamber about where the leave sit in registry number 5, again from Shiloh.

Chase and muzzle rings completed the form of the 24-pdr Field Howitzer Model 1841.  So outside of the handles and recessed breech, these weapons look much like an enlarged 12-pdr Field Howitzer of the same model year.

Profile of Alger No. 5

Alluded to above, there was a break of sorts in the production of 24-pdrs.  Collectively Alger and Ames delivered around twenty prior to 1848, filling requirements for the peacetime “mixed batteries” with two howitzers and four guns each.  Production resumed again in 1858 with 10 from Alger.  Then in 1862-63 the Federals received about forty more from Alger and Ames.

This of course begs the question, why at a time when the Models of 1841 were being phased out, were the 24-pdrs arriving from the factory?  My guess is the piece performed at least adequately in the field, and of course the type was useful in fixed fortifications also.  Certainly the 24-pdr bronze, at 1320 pounds, was more useful tactically than the 24-pdr Iron Siege and Garrison Howitzer at 1500 pounds.

The 24-pdr Field Howitzer, while not perhaps as popular as the Napoleon which I’ve compared it to, did see a fair amount service during the war.  In addition to Shiloh, western batteries used the type at Vicksburg and other battles up to 1864.  The type remained in the siege trains for Federal armies east and west, and was employed at Petersburg and during the Atlanta Campaign.  A 24-pdr “brass” howitzer featured prominently in the fighting at Monocacy in July 1864.  The crew incorrectly loaded the piece in the heat of combat, rendering it useless, however.  Even as late as 1877, Army manuals required accounting of the weapon and supporting tools.   The Confederates produced a small quantity of their own (which I will focus upon in another post), and also used captured examples.

The plaque in front of Alger foundry’s No. 11 states the Confederates used this particular piece to defend Morris Island, outside Charleston, South Carolina.  The howitzer was taken as a trophy for the Navy’s participation in the siege and reduction of the works, and today stands in Leutze Park, in Washington Navy Yard.  So these weapons were found useful by both sides during the war.   And as time permits, I’ll go into the Confederate use of these weapons, the imported foreign types in the caliber, and the use of the iron siege howitzer mentioned above.

But for now in summary, consider that while 100 pounds does not sound like a lot, it was enough to limit, tactically speaking, the 24-pdr Field Howitzer as a weapon system.

HMDB Civil War Updates – Week of October 26

Forty-three new entries this week in the Civil War category at Historical Marker Database.  States represent Alabama, Connecticut, Georgia, Indiana, Maryland, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Virginia, and West Virginia.

– A memorial stands near the grave of John Pelham in Jacksonville, Alabama, featuring a statue of the “Gallant” Confederate officer.  We have grouped a related set of entries that highlight the career of Pelham.

– A plaque in Ridgefield, Connecticut indicates a bell on display was captured by Colonel Alexander Warner and presented to the one of the state’s governors.  No indication of where the bell was captured, but it was cast in Cincinnati, Ohio in 1845.

– A state marker in Lawrenceville, Georgia details the story of Richard Dickinson Winn and family.  Richard Winn was a politician of note and a delegate to the state secession convention.  Four of his sons served the Confederacy, including Samuel who commanded the 13th Georgia Cavalry.

– Not often do we get an entry that explains the history behind another entry.  Such is the case with a wayside type marker in Vincennes, Indiana which references the nearby memorial dedicated to the veterans from the county.

Robert Moore added an entry from Clear Spring, Maryland which discusses Dam 5 on the Potomac River.  Recall this dam resisted the efforts of “Stonewall” Jackson in December 1861, as he attempted to disrupt the Chesapeake & Ohio Canal.

– A plaque in New York City highlights the service of the 9th New York State Militia (also known as the 83rd New York Infantry).  The regiment was headquartered at the spot.

Plato Durham, a Confederate officer and later political leader during the Reconstruction period, lived in Shelby, North Carolina.  The town also boasts the Cleveland County Confederate memorial.

– A state marker in New Bern, North Carolina indicates the site of Fort Totten, one of the defensive works built by Federals during the occupation of that city.  (Not to be confused with the fort by the same name that defended Washington, D.C.)

– A marker near Kinston, North Carolina provides details of the March 1865 battle of Wyse Fork.  It complements a nearby memorial to General Robert Hoke.

– Greenlawn Cemetery in Columbus, Ohio contains a Franklin County Civil War Memorial; and another to the unknown dead buried in the cemetery.

– Doylestown, Pennsylvania features a memorial to the 104th Pennsylvania Infantry Regiment formed in Bucks County.  The monument provides a detailed history of the regiment’s service.  A nearby marker mentions Camp Lacey where the regiment trained.

– A state marker in Montgomeryville, Pennsylvania notes the birthplace of General Winfield S. Hancock.   Hancock was laid to rest in Norristown, but while we don’t have a marker indicating that entered as of yet, one of our frequent contributors added the Montgomery County Civil War Memorial which is in Norristown.

– Another state marker in Shohola, Pennsylvania notes the site of a July 1864 train wreck.  About 48 prisoners and 17 guards en route to Elmira Prison in New York were killed.

– The Kershaw House in Camden, South Carolina was used as a depot during the war.  The building has an interesting history, having also served as Lord Cornwallis’ headquarters for a time in the Revolution.

– The Civil War memorial in Marion, South Carolina features a statue of a soldier “at the ready.”

– Our correspondent in the Richmond area added a trio of entries from the Confederate capital.  The entries start with an overview Civil War Trails marker at the Tredegar, and continue with entries for the Confederate Navy Yard and Rocketts Landing.  While not specifically Civil War related, I would also call attention to the entry for the Great Ship Lock marker, also near the navy yard.

– The New Kent Road in James City County, Virginia, was used by Lord Cornwallis’ Army (twice in one week) in 1781, then witnessed marching armies again in 1862 during the Peninsula Campaign.

– The activity of horse stabling connects two churches in Virginia with marker entries this week.  The Olive Branch Christian Church near Williamsburg served as quarters for Federal troops, and their horses were stabled in the sanctuary.  The North Farnham Church, closer to Richmond, was also used for stabling.  The later also bears bullet holes from a British raid during the War of 1812.

– A simple set of memorials recalls the Confederate soldiers of Prince George County, standing on the grounds of the county court house.

– A set of markers entered over the last two weeks cover the Rich Mountain battlefield.  The victory there in July 1861 propelled George McClellan to higher command, and helped secure West Virginia for the Union.

– I am working on a set covering a battle which followed Rich Mountain, at Corrick’s Ford near Parsons, West Virginia.  Those should be complete over the next few days.

That’s all for this week.  There are at least ten more entries in the editors queue for next week, so I’ll have more Civil War stories to relate from the markers to follow.

My Take on the Goings at Gettysburg

Of late I’ve been involved with several “discussions” on other venues with regard to the reassignment of Gettysburg National Military Park superintendent John Latschar and the details behind this action.  I say discussion loosely as to some degree such expanded into a heated debate over peoples alleged conceptions of the world. I got rather long winded over on Eric Wittenberg’s blog, and said probably more on the subject than I normally would.

Sort of a violation of my own rule – never make more than two comments on a subject as that implies I should either be discussing it here or dropping it as off topic.  I really need to stick to my own rule.  Call it good blogging habits, or simply being kind to those who run those other blogs.  But I wince thinking of the time blown typing responses within what is really a topic none of us has any real sway over.  As one friend put it, “we don’t have a dog in that fight.”

But I feel I should clarify the statements as to avoid misunderstandings and misconceptions as to my stance.  While I recognize that Mr. Latschar accomplished much in his tenure at Gettysburg, I don’t think we should simply look the other way with regard to the negative aspects of that tenure.   When you take the measure of a man, you must consider the sum of all his parts.  In short, I don’t see Latschar as an example of how to “fight the good fight.”  And I think trumpeting his accomplishments without considering similar advances and improvements in other parks, is marginalizing the work put in by the respective leaders and staff of the other parks.

To further expand, consider for a moment the status of the National Parks, and in particular the Battlefield Parks in the early 1990s.  In those days I was an infrequent visitor to the parks, due to military deployments.  But even as occasional visitor I easily noted the impact of a sagging economy, limited funding, and, most disheartening, lack of public interest.  I recall issues with general upkeep of the parks – deteriorating cannons and monuments, aged interpretive markers, overgrown trails, worn out roads, and limited faculties.   Harder to accept, however, was the increasing encroachment by development at some of the battlefields (which I contend is more a function of that “lack of public interest” cited above).

Let’s assume for a moment we had to grade each park on a scale of 1 to 100 in terms of quality – measuring the accessibility factors, appearance and upkeep, relevance of interpretation, preservation of resources, and overall experience.  I personally would have graded Gettysburg with a 60 or 70 score back in 1994.   Gettysburg still had the “tower” looming like some alien craft.  The park did not have a wide range of options for access – it was car or horse with a few foot paths.  But the visitor center was pretty good as far as the 1990s went, with that fabled electric map and excellent bookstore – heck I allocated at least an hour on every visit to browse the shelves.  And the park was generally well kept.

On the other hand Monocacy, a nearby and smaller battlefield, I’d have given a 35 or 40.  The park suffered from patchy coverage, with development threatening.  Interpretation was dated, in large part consisting of monuments erected by the veterans of the war.  The visitor center was stuffed into one of the park’s historic structures and was inadequate.  No trails offered the visitor a chance to see the battlefield up close.  The Washington Post even called the park a pork project,  lamenting $8.8 million was dropped in to support a backwater battlefield.  A poor state of affairs.

Now visiting both sites today, I would move up those scores.  Gettysburg, in my opinion would score between say 85 and 90.  There are areas to improve, to be sure.  The trail system at Gettysburg is still lacking (Antietam is the “gold standard” of eastern parks in this regard).  But the improvements with the tree line clearing and better interpretive markers are welcome.  I’ll keep my opinion about the new Visitor Center and Museum off the table for now, but will draw the comparison to the $100 million spent there and the $8.8 million at Monocacy in 1993.  But overall Gettysburg has indeed improved.

Now how about Monocacy?  I’d rate it at 70 to 75.  Visitor center moved to a better location, and is just the right size for a small battlefield.  Much more interpretation on site.  Very well crafted and maintained trail system.  AND an enlarged battlefield that, while still threatened, is not a patchwork of managed fields.  Yes, I-270 and the railroad cut through the heart of the battlefield, but in their defense, how do you move those things?  The park is working to mitigate such intrusions and of course, has a plan out for public scrutiny.

I know these are subjective measurements, and I’ll stand to for cross examination, but I think that Monocacy improved more, relatively speaking, than Gettysburg.  Monocacy had less resources, less funding, and less to start with.  And at the same time, got less attention from both the news media AND us Civil War enthusiasts.

Monocacy is not just an isolated case.  When I compare photos of Antietam from the 1990s, in some ways it seems to be a different battlefield and the interpretation (added this year BTW) is excellent.  I would argue the tree clearing at Manassas, have had a greater impact, visually, than that at Gettysburg.   The Fredericksburg-Spottsylvania Battlefield also received an interpretive “facelift” of sorts, with additional acreage added through alliances with local preservation groups (arguably not enough though).

We here in the east tend to forget about the parks like Shiloh, Chickamauga-Chattanooga, and Vicksburg, all of which are undergoing similar improvement cycles.  The Pea Ridge National Battlefield Park benefited in recent years from a strong “friends of the park” movement, restoring not only the wood lines but the fence lines.  If Monocacy jumped its score by 35 points, perhaps Pea Ridge improved by 40!

But, does anyone reading this (outside of those who work at those parks) recall the name of the superintendents of any of those parks?  When is the last major news article posted that mentioned any of them?  Yet have those other superintendents and park staff worked just as hard to improve their respective parks?  Do they not deserve attention?

Here’s my bottom line – I want to hear the stories of those out there “fighting the good fight” for preservation.  Those are the folks whom I’d prefer to uphold as examples.  If anything, what the Latschar incident has inspired me to do is seek out those such examples.  I’ll do my best to pass such examples along to those I meet – both in person and here in the blogosphere.
