Light gun for inshore duties – 12-pdr, or 3.4-inch, Dahlgren Rifled Boat Howitzer

On September 15, 1864, Brigadier-General Rufus Saxton made a request for naval support to help picket the backwaters behind Morris and Folly Islands:

I have the honor very respectfully to request that, if consistent with the interest of the service, a navy launch, manned and armed with a rifled 12-pounder howitzer, may be placed on picket service in the creeks opposite Long Island and in Stono and Folly Rivers.  Such a boat will be of very great service there.

Although the Army’s forces had long patrolled and picketed the marshes in that sector, recent reductions in the force left them short of personnel.  Shifting light artillery to other sectors (such as guarding the 600 Confederate prisoners) meant the Army had few field pieces –  which were unsuited for duty in the marshes to begin with.  Aside from the little mountain howitzers, the Army’s system of artillery lacked anything light enough for handy operation in the boats used in the backwaters and bays.

The 12-pdr rifled howitzers were used often around Charleston during the war.  I’m of the mind these weapons were valued due to greater accuracy at long range when compared to the smoothbore howitzers.  Let me reach back to some charts posted several years back to demonstrate the characteristics of these rifled boat howitzers.  First comparing the different types of Dahlgren Boat Howitzers:

The Navy introduced the 12-pdr rifle (next to last column on the right) in 1861.  The rifle used the same bronze casting as the 12-pdr Heavy Boat Howitzer (second column from the left), but with a 3.4-inch rifled bore.  Early rifles had three groove rifling.  That was later increased to 12 grooves.  The smaller bore diameter translated to a slight increase in weight of the weapon to 870 pounds.  That meant the rifle was slightly heavier than a standard Army 12-pdr field howitzer.  But because the rifle used the Dahlgren carriage, overall weight remained lower than the Army type in action.

The 12-pdr rifle fired shot, shell, and case shot (shrapnel).  The Navy Ordnance Instructions of 1866 credit the 12-pdr rifle with a range of 1,770 yards at 5º elevation using a 1 pound powder charge (time of flight was 6 seconds).    That compared to 1,085 yards for the same powder charge and elevation for the smoothbore 12-pdr Heavy Boat Howitzer.

During the Civil War, the Navy received 423 of these 12-pdr Rifled Boat Howitzers.  The rifles saw frequent use during the war, particularly around Charleston.  Aside from the Army’s request, the 12-pdr rifles were used from the decks of the monitors to fire upon grounded blockade runners.

Having established the weapon’s importance at this time 150 years ago, let me turn to a pair of the fifteen survivors for a walk-around.  Two 12-pdr Rifled Boat Howitzers are on display today at Battery Jameson, part of Fort Lincoln, in Brentwood, Maryland… allowing me to bridge wartime activities at Charleston back to Washington, by way of John Dahlgren and the Washington Navy Yard!

Bladensburg 110

The two howitzers are registry numbers 211 and 250, both produced by the Navy at the Washington Navy Yard.  (Ames Manufacturing also produced 26 of this type in 1862.) From a distance, the rifles have the same appearance as the 12-pdr heavy smoothbores:

Bladensburg 122

Notice the location of the fixtures, particularly the lock-piece mount, rear sight base, and pierced knob.  Again much the same as with the smoothbore gun:

Bladensburg 111

The measure of axis for the lock-piece was the same as on the smoothbore:

Bladensburg 116

Looking at the muzzle, we see the difference with the rifle:

Bladensburg 121

Yes, 12-groove rifling:

Bladensburg 119

The rifle retained the front sight base.

Bladensburg 114

Markings on the barrel also give away the type:

Bladensburg 113

In this case – Rifled 12 pdr // Boat Howitzer // 1863 // J.A.D.  The later being Rear-Admiral John Dahlgren’s initials.  There are other markings on these howitzers, and some are rather interesting in regard to the “administrative” history of the guns.  But due to the years of exposure, many have been obliterated.

There are some interesting variations among surviving 12-pdr rifled boat howitzers.  Some were bored out from rifles to be standard 12-pdr smoothbore weapons.  The assumption is the Navy learned, as did the Army, that bronze was not good for rifled guns.  There are a few of the steel versions around, which I’ll show in a walk-around at a later date.  At least one 3-groove rifling version has survived.  At least one was converted to brechloading, either for experiments or as a saluting piece.  Also there were several steel guns cast by Norman Wiard.  Those should not be confused with Wiard’s “puddled wrought iron” rifles of the same caliber produced for the Army’s “Marine Artillery” and used in North Carolina.

Dahlgren’s 12-pdr Rifled Boat Howitzer was mentioned on several occasions in correspondence and reports.  All indications are the weapon served its purpose well.  But as with all bronze pieces of the era, it was eventually rendered obsolete with the arrival of steel breechloading weapons.

James Pike – Soldier and POW? Or Sabatour and spy?

At the end of the Civil War, James Pike, of the 4th Ohio Cavalry, wrote an account of his exploits, titled “The Scout and Ranger: Being the Personal Adventures of Corporal Pike.” The front piece plug is perhaps the best argument for adding this to your reading list:

As a Texan ranger, in the Indian wars, delineating western adventure; afterwards a scout and spy, in Tennessee, Alabama, Georgia, and the Carolinas, under General Mitchell, Rosecrans, Stanley, Sheridan, Lytle, Thomas, Crook, and Sherman. Fully illustrating the secret service.

Lots of names dropped… and secret service!  But caution is always the approach with post-war accounts.  As any Civil War enthusiast knows, there’s enough post-war accounts of the Civil War to make up a couple of wars.  And not all of it squaring up nicely.

Where the Pike story gets my attention is his time as a prisoner in Charleston, 150 years ago from the summer of 1864.  He appears in correspondence between Major-General John Foster and Major-General Samuel Jones as they exchanged messages about the larger prisoner issue.  Some have tried to isolate specific portions of the POW dialog.  But I tend to group these as one important issue – how prisoners were handled in 1864 going into 1865 – policies and actions included.  The nature of Pike’s time as a prisoner is just part of a larger context.

Let me provide the short version of events leading to Pike’s capture (and I would point out, this was Pike’s second such capture!). Late in the spring of 1864, Pike and Private Charles Gray, of the 5th Iowa Cavalry, ventured into South Carolina opposite Augusta, Georgia.  Their aim was to burn the railroad bridge there. But they found it well guarded.  On the return to Federal lines they were discovered, chased, and captured (on or about June 5, if my math is correct) near Edgefield, South Carolina.  Dressed in civilian clothes, Pike and Gray confessed to being “scouts.”  Under the conventions of the war, they were, however, suspected of being spies.  The two spent 57 days confined in Augusta during which they “were so starved as to be mere shadows.”

In the first week of August, Confederates transferred the two men to Charleston where they would be some of the many prisoners then under Federal fire there.  These two men, however, were held in the tower of the Charleston Jail under close confinement and limited rations.  A month later, their case caught the attention of Foster, raising the subject in a September 5 letter to Jones:

I am informed by an officer recently arrived from Charleston that James Pike, of the Fourth Ohio Cavalry, and Charles R. Gray, of Fifth Iowa Cavalry, are held by you in close confinement at the jail tower in Charleston, and kept upon a prison diet of mush and water.  Also that these men have been informed that they are held and are to be tried as spies.  I further learn that they were captured on or about June 5 last, near the Hiwassee River, in Southwestern Tennessee or the northwestern part of South Carolina, and that, when taken, they were wearing our uniform and had arms in their hands.  If their claim in this respect is true, they are entitled to be treated as prisoners of war. I respectfully ask you to have their case investigated and extend to them the treatment usually accorded to prisoners of war among civilized nations.

Granted, the story related to Foster appeared to be incorrect in regard details of the capture. But the notion was set – the Confederates were not correctly handling prisoners of war.  That idea had ground to take root given the Confederate treatment of captured USCT.

Jones responded on September 10:

In reply to your letter of the 5th instant in regard to James Pike and Charles R. Gray, I have to say that they were arrested in Edgefield District of this State.  They were not in U.S. uniform when captured, and had about their persons certain papers which warranted the belief that they were spies.  They are confined, as usual in such cases, and will be accorded a fair trial.

Foster received this note a few days later, countering on September 13,

These statements are ad variance with information in my hands. I desire to acknowledge your assurance that they shall have a fair trial, and have the honor to request that when they are tried you will furnish me with a copy of the proceedings, and also of their sentence in case they are convicted.

Perhaps Foster had another “tit-for-tat” retaliation in mind.  Certainly the Federals had plenty of “spies” and other irregulars in hand.  And that seemed very likely as events played out into the fall.

In November, recently exchanged Acting Ensign Thomas Stokes (he’d been captured the previous spring at Plymouth, North Carolina) brought more information about the prisoners.  Stokes wrote to Pike’s father and to Major-General George Thomas, commanding the Army of the Cumberland.  Thomas responded in a tone very similar to Foster’s in regard to other prisoner issues at Charleston:

Respectfully referred to the Commissary-General of Prisoners, with request that two rebel prisoners of war be selected as hostages for the within-named men, viz, Corpl. James Pike, Company A, Fourth Ohio Volunteer Cavalry, and Private Charles R. Gray, Company D, Fifth Iowa Cavalry, two scouts sent by me into the country occupied by the rebel army in May last. I would also request that the rebel authorities be informed that hostages have been selected and will be subjected to the same treatment as they inflict upon the two soldiers named.

The War Department approved this request.

Eventually, Pike would gain his freedom (otherwise how would we have the book?).  When the Confederates evacuated Charleston in February, he and other prisoners were removed inland to Columbia, South Carolina and then forwarded to North Carolina.  Along the way, Pike managed to get away.

In relation to the prisoner-related affairs at Charleston, Pike’s experience is worthy of note. The Federals were willing to match “an eye for an eye.”  Even if where the offenses were perceived more than actual fact.  And this attitude was not restricted to Foster at Charleston… nor to abolitionist-leaning officers.  Three years of war has a way of hardening one’s sentiments.

Perhaps the last word on this should be from Pike himself, describing the conditions he survived:

But why add more relative to the horrors of this filthy pen?  He who has never experienced the torture of a Southern prison-house can form no idea of the wretchedness inclosed; while the tens of thousands who have been incarcerated therein, but who have been fortunate enough to escape death, need no words that they may appreciate the cruelties inflicted.

Star Spangled 200th at Fort McHenry

Today marks the 200th anniversary of the bombardment of Fort McHenry and the events which inspired our national anthem.  I am taking a break from my Civil War focus to attend this War of 1812 anniversary.  Fort McHenry National Monument and Historic Shrine plays host to a weekend packed with events to commemorate this defining moment in American history.  My aide-de-camp has already nodded approvingly of the airshow and tall ships.

If you cannot be at Fort McHenry, you can follow along by way of social media.  The park’s Twitter and Facebook pages are frequently updated.  The hashtag is #StarSpangled200.  There’s also a set of web-cams up.

I’ll be out at the fort most of the day.  So check Facebook and Twitter for updates!
