I try to make history readable and interesting, warts and all. We must look to the past to understand the present and confront the future.
Worse Than Poison Gas? Ask the Moro
Having been the first to unleash unrestricted submarine warfare, poisonous gas and the flammenwerfer, a one-man flamethrower, on their enemies, the Germans finally found a weapon too horrific for use during the Great War. It was the shotgun that American troops brought to the front in 1918.
In 1900, during the Philippine Insurrection, Captain John Pershing saw combat against the Juramentados, fanatical Islamic Moro swordsmen who sought martyrdom while killing their enemies. The Army Colt .38 didn't stop their suicidal attacks and even the Springfield rifle didn't always do the job. In such close quarter fighting, the Model 97 Riot Gun, a pump-action shotgun, usually gave the Juramentados their desired martyrdom.
Captain John Pershing
General Pershing Remembers the Moros
As commander of the American Expeditionary Force in France, then General John “Black Jack” Pershing, saw the need for close-range firepower when fighting in the trenches and remembered the Juramentados. He had the Ordinance Department work with the Winchester Repeating Arms Company to modify their Winchester Model 1897 shotgun.
Original Civilian Version
The Weaponized Shotgun
What evolved was the Model 97 Trench Gun, a pump-action 12-gauge shotgun with a 20-inch barrel, a sling swivel and a bayonet adapter with a perforated metal heat shield over the barrel. Without the heat shield, the barrel could get too hot to hold when using the bayonet. With one “in the spout” (chambered) and five in its tubular magazine, the Trench Gun could hold six shotgun shells. Normal cartridges made of a brass base with a cardboard tube were unfit for the terrible conditions at the front. The cardboard, when wet, swelled up and jammed, so all-brass cartridges were issued. Each 2-3/4 inch shell contained nine 00 (double-aught) buckshot pellets, each with a diameter of 8.4mm (.33 inch).
The Winchester shotgun also had a slamfire mode. With an ordinary pump-action shotgun, the shooter ejects any spent cartridge and chambers a shell by pulling back on the pump (the sliding forearm handle) and pushing the pump forward. Then the shotgun can be fired by pulling the trigger. By squeezing and holding the trigger while pumping, the Trench Gun would fire every time the pump was pushed forward. A trained soldier could fire six shotgun blasts with devastating effect against unarmored targets in less than two seconds. A canvas pouch held an additional 32 shells, but, if he couldn't reload, he still had his bayonet.
Trench Brooms and Sweepers
By June 1918, there were only enough to supply each division with 50 Trench Guns, but they were put to devastating use. When soldiers equipped with Model 97 Trench Guns jumped into an enemy trench, they were able to clear it quickly in both directions using the slamfire mode. The relatively short barrel length allowed them to quickly swing in either direction in the narrow, confines of the trench. In a matter of seconds, 54 8.4 mm balls of buckshot with an effective range of up to 50 yards tore up anyone in the way. Such firepower, restricted to close-in fighting, had a greater hit probability than any available automatic weapons of the time. They became known as trench brooms or trench sweepers.
General John J. Pershing
Soldiers With Trench Guns Will be Executed
The enemy didn't like the trench broom one bit. In September 1918, the German government issued a diplomatic protest, complaining that the Model 97 Trench Gun was illegal because “it is especially forbidden to employ arms, projections, or materials calculated to cause unnecessary suffering” as defined in the 1907 Hague Convention respecting the Laws and Customs of War on Land. When the Americans rejected this, the German high command then threatened to execute any soldier caught with a Trench Gun or even just Trench Gun shells. General Pershing replied that, henceforth, any Germans caught with flamethrowers or saw-bladed bayonets would be lined up and shot. As far as is known, no American or German POWs were executed under such circumstances.
Sergeant Fred Lloyd?
There are many references to an American soldier single-handedly clearing a German-held French village on September 27, 1918. Supposedly, Sergeant Fred Lloyd methodically moved through the village pumping and firing his Trench Gun and routing thirty German soldiers until he finally collapsed with exhaustion from the effort. Many of the references are identically worded. Until corroborating sources are found, this shall remain a questionable sidebar.

Questions & Answers
Question: Excellent article. May I add that soldiers armed with shotguns were picked strategically for their skills of blue rock shooting? They were strategically placed in the battlefield to shoot German grenades out of the air. I won't waste my time beating the dead horse of how hypocritical the Germans were, but interesting history nonetheless. It seems funny to me how leaders can expect men in the front lines to follow rules of engagement or codes of conduct.
Answer: You raise an interesting point. The reason I didn't mention Americans shooting grenades out of the sky is because I couldn't find verification that this was effective. I've seen videos where expert marksmen (and markswomen) attempted to do this and it is extremely difficult to even hit a moving grenade when (unlike a skeet shot round with many tiny pellets) the combat round had only 9 large pellets. I have no doubt the troops did this but it probably was relatively ineffective. But many thanks for bringing this up and addressing this use of the shotgun!
Question: "The weaponized shotgun". Do you mean "militarized"?
Answer: Both terms are correct but I do believe "militarized" is a more accurate term.
Question: Isn't it now called The Philippine-American war, not the Philippine Insurrection?
Answer: Actually, there are several names for the war: the Philippine–American War, the Filipino–American War, the Philippine War, the Philippine Insurrection or the Tagalog Insurgency.
Question: Did the Model 10 shotgun see similar successes to the Model 97 or was it overshadowed for a reason?
Answer: The Remington Model 10 shotgun did indeed see service in WW1 along with Winchester's Model 97 but the Model 97 was first (proving the concept) and many more of them were used during the war. When Winchester could not keep up with demand, the government asked Remington to militarize its Model 10. Because of patent infringement (business trumps war) Remington had to devise a different bayonet mount and used a wooden heat shield. Both shotguns employed the slam fire mode. The Model 10 did have an advantage in that both the loading and ejection of cartridges was through the underside opening. The Model 97 had an opening on the underside for loading, an ejection opening on the side and a hammer-cocking opening at the back-- three places where dirt and mud could foul the weapon instead of just one.

What an interesting read. Thanks for posting the article, it would be great to hold of an 1897 winchester one day!
Bearclaw Chris on May 05, 2019:
I sent you an email by mistake, I meant it as a comment.
I thoroughly enjoyed this article. However there is an interesting fact that was left out.
Aside from being really good at clearing trenches, 1897's were given to strategically picked soldiers, who showed skill in blue rock/clay bird shooting. They were strategically placed throughout a trench to deter German grenades from entering a trench. I have personally shot blue rock with buckshot, I can tell you it is challenging compared to a standard 8shot target load.
The more I learn about this shotgun, the more I love mine.1897s are pretty easy to find, despite most of them being originals. Mine was produced in 1906, and is all original numbers matching.

Great article! Detailed and fascinating.
Hurley T. MacMaster on February 18, 2018:
Read about this in The American Rifleman. I love the greater detail of the story.
David Hunt (author) from Cedar Rapids, Iowa on January 09, 2018:
True, the French used gas in August 1914, but it was tear gas. The first major use of poisonous gas was by the Germans in 1915.
Jeff on January 09, 2018:
The French were the first to use gas in August 1914, not the Germans. The French were also the first to use the flamethrower at Vauquois.
Although the Germans were the first to use gas on a large scale, it was used as a defensive strategy. Keep in mind, phosgene gas made up the vast majority of gas casualties in WW1, and it was invented by the French. Germany also used the flamethrower in far greater numbers at Verdun, but they were not the first to use it.
Protesting the M1897 was not an unreasonable thing at all. Unlike poison gas (which was used as a defensive weapon), buckshot was designed to kill. The wounds were incredibly hard to treat and caused unnecessary suffering. The same goes for the sawtooth bayonet. Those weapons were unnecessarily brutal.
Jimbo on January 07, 2018:
Great stuff! I have seen photos of civil war dragoons and light cavalry from both sides armed with double barrel shotguns. They were also used in the war of 1812 and the Mexican war. US forces have always used shotguns. Even the Army of the Republic of Texas used them against both the Mexicans and the Comanches. Maybe Europe found them unusual, but the US is always going to use them.
David Hunt (author) from Cedar Rapids, Iowa on September 11, 2017:
The Declaration of St. Petersburg of 1868 (which predates the Hague Convention of 1899) prohibited the use of exploding bullets (small arms projectiles designed to explode inside human flesh), considered to be inhumane.
Laurence Daley on September 11, 2017:
During the Cuban vs Spanish 1868-1878
both sides were using Remington explosive bullets
would that be considered inhumane
Adrian Popa Chris on January 23, 2017:
I got so deep in the information about shotguns and i never thought that shotguns were actually used in a war,WW1 was one of the most cruel wars ever.When i read that shotguns got baned cause of their affectiveness on close quarters combat i was like,nigga this is some big bullshit...Germans complaining about shotguns.I dont know why Germans complain in the first place,that they"cause unnecessary suffering" well hell they do,but it's not worse than Gas and Flamethrowers.Even in video games shotguns are underpowered,when you shoot them you feel like you shot paper balls out of it,not pellet's or slugs. And even Armies around the world dont use shotguns and i dont know why,maybe because of the reload speed? Cause i know for a fact that a 44. slug coming out of a 12 inch barrel can kill someone even in 200-300 yards away..that's pretty far i must say.
Great article,Maybe sometime soon shotguns will get the love that they deserve. I really enjoyed reading your article! Have a nice day/night
AI on June 12, 2016:
To be fair, as a common grunt in the trenches, I'd consider being on the receiving end of an American trench gun AND a german flamethrower to be quite inhumane...
David Hunt (author) from Cedar Rapids, Iowa on February 23, 2016:
Glad you liked it, Edward. Yes, the German objection to the shotgun was quite ironic. Apparently drowning with fluid-filled lungs and huge running blisters all over your body or being covered with burning napalm was preferred to having OO buckshot tear through your body. None for me, thanks.
Ed Palumbo from Tualatin, OR on February 23, 2016:
I found this very interesting. The Model 97 was still in use by the U.S. Marine Corps when I was a young M.P. in the mid-'60s, but has since been "retired" and replaced by Remington and Mossberg 12 gauge pump shotguns. To its credit, the Model 97 was well-built and reliable. A shotgun loaded with OO Buck is a formidable weapon, but I hadn't realized the Germans perceived it as inhumane and against the rules of warfare. That seems bizarre since the Germans were quick to rely on chemical weapons that were clearly against the 1899 Hague Declaration. Thank you for an interesting Hub!
FlourishAnyway from USA on February 07, 2015:
This was not only informative (given all that happened in both WWI and II who would imagine this?) but it also well written.
Kenneth Avery from Hamilton, Alabama on September 13, 2014:
You are more than welcome. Frankly, you DESERVE a lot more cudo's for such a fine work. I enjoyed reading this information that the documentaries about war times does not touch.
Thank you again for sharing this priceless information. Keep up the fine work and hey, thank you too for the following.
I will treasure that as long as I am alive.
David Hunt (author) from Cedar Rapids, Iowa on September 13, 2014:
Kenneth, I am speechless ( an unnatural condition) and humbled (again, unnatural) at such praise. Thanks for making my morning.
Kenneth Avery from Hamilton, Alabama on September 12, 2014:
I love this hub. And here are the reasons why:
1. This is an excellent piece of writing. Honestly, it is amazing.
2, I loved every word.
3. Graphics, superb.
4. This hub was helpful, informative and very interesting.
5. Voted Up and all of the choices.
You are certainly a gifted writer. Keep the great hubs coming.

David Hunt (author) from Cedar Rapids, Iowa on August 22, 2014:
Thanks for your generous comment, Michael. Irony abounds in war. I didn't know anything about the American shotgun until very recently and when I saw that the Germans declared it inhuman, I knew I had a hub.
Michael Kismet from Northern California - Follow me on Twitter! -> on August 22, 2014:
Wow, I always manage to learn something new and so interesting from your hubs. The Germans before world war 2 considering something "inhumane", that's some irony for you.. War is a bloody business, always has been, always will be, a sad truth indeed. Looking forward to more of your insightful and fascinating articles, great post!
David Hunt (author) from Cedar Rapids, Iowa on August 20, 2014:
Thanks for commenting, pmorries. Interesting about the "fish hook" gun. Never underestimate the ingenuity spurred by military need-- real or imagined.
pmorries from Golden, CO on August 20, 2014:
...Captain John Pershing saw combat against the Juramentados, fanatical Islamic Moro swordsmen who sought martyrdom while killing their enemies. The Army Colt .38 didn't stop their suicidal attacks and even the Springfield rifle didn't always do the job. In such close quarter fighting, the Model 97 Riot Gun, a pump-action shotgun, usually gave the Juramentados their desired martyrdom.
What I fond interesting is that history repeats itself. American special forces have had to change their guns, because our guns are made to wound- not kill. The theory being you wound one soldier, and it takes another soldier to take care of him.
Terrorist on the other hand, keep on fighting even when wounded, so we have had to move to bigger or stronger rounds.
In closing, I have heard about a gun that fired a round that was similar to fish hooks (barbed rounds), but it was banned for being too cruel .

War is crazy, insane and illogical. We cannot expect the rules of war to be otherwise. Thanks for reading and commenting, Larry.
Larry Rankin from Oklahoma on May 14, 2014:
Great read. I have always been fascinated by the regulatory rules of war. Just seems like such an abstract concept to me. It also is strange to want to outlaw something like a shotgun when poisonous gas is being used. Fascinating stuff.
David Hunt (author) from Cedar Rapids, Iowa on May 06, 2014:
I know what you mean, Theresa. I sure wasn't thinking about writing a hub about a shotgun in WW1-- there were so many other technical "achievements" during that war. But when I read that the Germans protested about the humanity of such a weapon, I just had to write it. Thanks for reading, commenting and sharing!
Theresa Ast from Atlanta, Georgia on May 06, 2014:
Harald, how fascinating. I had never heard anything about this. What an amazing and unexpected weapon. And how unbelievable that the Germans, with flamethrowers no less, should have indignantly pronounced this an unacceptable and cruel weapon.! Great Hub. Sharing. Theresa
David Hunt (author) from Cedar Rapids, Iowa on April 24, 2014:
Graham, great to hear from you. I also thought the brass cartridges were interesting. There are some shown at the end of the video of the woman shooting the Trench Gun.
Graham Lee from Lancashire. England. on April 24, 2014:
Hi David. A fearsome weapon indeed. It must have taken time to develop the heat shield to do a worthy job. Interesting to note the brass cartridge requirement. Great research as usual.
David Hunt (author) from Cedar Rapids, Iowa on April 23, 2014:
CMHypno, the cynic in me has always wondered about the rules of war and what's really behind them. Violently inserted bits of metal into human bodies has been a time-honored tradition for a long time, but there are rules forbidding dum-dums (expanding slugs), non-jacketed slugs, use of .50 caliber machine-guns against individuals, etc-- all in the name of "humanity". War is hell on Earth, but I'm always left wondering... what else can you do when soldiers are attacking your town other than fight fire with fire? And it's not the soldier that starts a war, it's the boys in the back room. Thanks for commenting.

CMHypno from Other Side of the Sun on April 23, 2014:
Interesting but horrific. It makes you wonder what the world would be like if we employed our skills and intelligence to improve the world, rather than find ever more efficient ways of killing each other. I agree with Alastar it was ironic in the extreme that the Germans protested, but if they had come up with the idea first I have no doubt they would have used trench guns.
David Hunt (author) from Cedar Rapids, Iowa on April 22, 2014:
Hi Alastar. Ironic to the extreme. As a matter of fact, it was the irony of the German complaint about the shotgun that drew my attention and prompted me to dig deeper. Thanks for reading and commenting.
Alastar Packer from North Carolina on April 22, 2014:
What a great article on the topic. How ironic that the combatant that introduced the horrors of poison gas first in action should have a prob with the generally more merciful shotguns of the Americans. The 'trench gun' was an awesomely effective close in weapon in the closing months of WWI. Guess the Germans just didn't count on all those squirrel hunters showing up.
David Hunt (author) from Cedar Rapids, Iowa on April 21, 2014:
Thanks for the comment, Phillbert. The Model 97 Trench Gun was still used in World War 2, though by then there were other, improved military shotguns. Glad you liked it.
Phillip Drayer Duncan from The Ozarks on April 21, 2014:
Great article! Very interesting to see where shotguns fell int0 military use. Personally, I feel that shotguns are the best home defense weapons available, and for the same reason that they were useful in a trench.
David Hunt (author) from Cedar Rapids, Iowa on April 20, 2014:
Thanks, krillco. You're right. Pershing was concerned about the constant counter-attacks that all too often erased any hard-fought gains the original attacker made and the trench gun was used to great effect defending against them.
William E Krill Jr from Hollidaysburg, PA on April 20, 2014:
Very nice piece; looks to be a great defensive weapon.
