That "Damned, Jammed Chauchat"

Issued to American Doughboys and Marines during World War I, the Chauchat automatic rifle was plagued with problems.


The French called it Le Fusil Mitrailleur 1915 CSRG. The Doughboys and Marines of the American Expeditionary Force called it “Show-Show” or “Shoo-Shoo”—or several other names that cannot be printed in this magazine. Few arms evoke such negativity from American servicemen of World War I, and no other firearm used in combat by U.S. troops has ever been as badly derided as the crude Chauchat. Yet, foreign and ugly as it was, the Chauchat was an important addition to Uncle Sam’s arsenal in the early days of 1917, and served our troops until peace was hard-won in November 1918.

The Fusil Mitrailleur 1915 (CSRG stood for Chauchat Sutter Ribeyrolles Gladiator) was well ahead of its time. When finally deployed in useful numbers in the autumn of 1916, Col. Louis Chauchat’s automatic rifle delivered a level of man-portable infantry firepower that was unrivalled in any other army. The M1915 CSRG heralded a new era of automatic arms as it could be carried, loaded and fired by just one man. But the Chauchat’s story is an unfortunate one because Col. Chauchat’s ingenious design was clearly let down by manufacturing standards that could be described as nothing short of criminally negligent.

A soldier’s first glance at a Chauchat indicated that there was something wrong or, at the very least, not right. The exposed metal parts appear rough, as does the slab wood buttstock, and the entire gun looks as if it is an unorganized conglomeration of sheet metal stampings and scrap parts. The Gladiator factory in Paris (where almost all of the manufacturing was conducted) appears to have had no affinity for quality workmanship, and reports of substandard materials and improper heat treatment haunted the CSRG throughout the war. From the moment of its introduction to American troops, the Chauchat’s awkward appearance did not inspire confidence in men used to handling well-finished arms.

Introduced into combat during the height of static trench warfare, the Chauchat suffered from the prevailing outmoded tactics of the time, as well as the harsh physical environment of the Western Front. One of the Chauchat’s greatest flaws was its flimsy magazine, which had a maximum capacity of 20 rounds of 8 mm Lebel ammunition. Unfortunately, the magazine springs were not strong enough; so most Chauchat gunners “short-loaded” their magazines for increased reliability. Even worse, the magazine was almost completely open on its right side (to provide gunners with a quick view of available ammunition), and this exposed the gun and its ammunition to all the mud, slime and grime that the trenches could provide. Too, the magazine feed lips were easily bent, and the entire magazine itself could be easily crushed or deformed.

With all of those problems considered, the Chauchat was not just prone to jamming, it was almost guaranteed to jam. Canvas covers were eventually provided for the magazines, and while this helped a little, the horrible magazine design was not corrected by the end of the war. While it may seem like an easy remedy to a completely predictable problem, it was not addressed in time to make the Chauchat a more dirt-proof design, and many French and American gunners paid for that fact with their lives.

Easily portable automatic arms were in short supply on both sides of the line on the Western Front. German troops were used to lugging around the MG08/15, in those days considered a “light machine gun” at only 40 pounds. Small wonder that the Kaiser’s men were keen to use any 28-pound British Lewis gun they captured. Not so, however, with the 20-pound Chauchat. Despite the large numbers of captured Chauchat machine rifles available to them, the Germans apparently made no attempt to use them. I have many photos in my collection of Germans using captured Lewis guns, but I have never seen an image of a German using a Chauchat in World War I.

Each time a Doughboy attempted to fire the Chauchat from the prone position he was painfully reminded that it was not a shooter-friendly design. To avoid a punch in the eye or cheekbone (the French called this “la gifle”), the shooter must position his cheek well forward of the plug end of the long-recoil mechanism. At the same time, the shooter must also hold the short buttstock tight to his shoulder to provide enough resistance for full cycling of the recoil system. As if the rifle were not already fraught with problems, the shooter must subordinate his natural instincts and fire it with awkward positioning of his eye, cheek and shoulder. Coupled with a spindly, unstable bipod and poorly aligned sights, accurate combat shooting beyond 100 meters with a Chauchat was quite an achievement. Hits at more than 400 meters were next to impossible.

Jamming the Chauchat was not limited simply to dirt entering through the open magazine. Overheating of the long-recoil action was unavoidable, but the burning question in the minds of Chauchat gunners was how many rounds would it take to jam it? Considering that a clean, well-oiled Chauchat (where would you find one of those in 1918?) would seize up after only 300 rounds of rapid fire, a dirty rifle could be maddeningly locked up after only 100 rounds. It would often take more than 10 minutes for the barrel and sleeve to cool off enough to allow the recoiling barrel to slide forward and lock in the firing position. No amount of kicking, hammering or cursing (in English or French) would release the jammed mechanism.

It is difficult for us to imagine today but the battle-readiness of American armed forces in 1917 was woeful. Colonel Isaac Newton Lewis (inventor of the Lewis light machinegun), provided this testimony before the Senate Military Affairs Committee on December 22, 1917: “The equipment of our troops in France, the pitiful handful of men, hardly equal to the casualty lists of the British that we get week by week—the equipment of those men is an outrage and a disgrace to this country. They have neither machine guns nor a suitable supply of rifles; they have no field artillery except what we are begging and borrowing from France, which is stripped to the skin. We are not going to get armament to them in ten months from today, nor one year from today. We will not have one million armed men in the field, because America will be absolutely unable to supply the arms and ammunition required. Somebody is responsible for that; something is responsible; some system is responsible for it.”

While Col. Lewis was incorrect in his prediction of America’s ability to field a well-armed expeditionary force within a few months, his assessment provides an accurate snapshot of the situation in late 1917. That predicament was one of the primary reasons the AEF needed arms such as the Chauchat. The need was immediate, and brilliant designs such as the Browning Automatic Rifle (BAR) were still just concepts or prototypes at that point—while American troops were already fighting and dying in France.

In a letter dated Dec. 5, 1917, the French High Commissioner wrote to the U.S. Chief of Ordnance: “I beg to state that I am informed by my government that the factory manufacturing the 25,000 Chauchat rifles for the American Army expects to have the whole lot completed about March, 1918. Under these conditions I am directed to ask you whether you will be prepared to place a further order and what will be the importance of this order. This information is necessary to plan out the output of the factories concerned for 1918.”

Beginning in August 1917 and concluding with the November 1918 Armistice, the Gladiator factory in Paris was responsible for delivering approximately 16,000 Chauchats chambered in 8 mm Lebel (“Balle D”) and then in 1918, approximately 19,000 M1918 Chauchats chambered in U.S. .30 cal. (.30-’06 Sprg.). While the original 8 mm Lebel Chauchat was problematic, the revised Chauchat in .30 cal. was close to unusable.

Crippling extraction problems were caused by incorrect chamber measurements and the pathetic manufacturing standards at the Gladiator factory were even more manifest in the .30-cal. version. American ordnance inspectors rejected as much as 40 percent of the .30-cal. Chauchats. The M1918 did provide an improved bipod as well as a proper detachable box magazine design (holding 16 rounds). But the .30-’06 Sprg. cartridge overpowered the flimsy Chauchat, and the rifle was damned from the start. Very few were issued to AEF troops.

My grandfather carried a Chauchat and claimed his M1911 saved his lifed on many occasions because his rifle was always jamming when he needed it the most.

Paul, how does the CSRG do with blanks? Are BFA's available for this weapon? I am a new GWA member considering a CSRG purchase. Any info you could provide on use of this weapon for "the wars" would be appreciated!

I wonder from what vast reserve of experience the author can back up such claims? Or is he, like so many others, simply parrotting the same tired embellished 90 year old war stories about the CSRG? How many magazines has he actually fired from a Chauchat? How many miles has he actually carried one in the mud and brush? How many jams has he actually cleared? I own two. They work fine. I know three other guys who own CSRG's and they all work too. If you take the proper care of your equipment, it will do its job. In years past I carried mine through mud and slop up to my knees in the trenches of the Great War Association site in Pennsylvania, and in Army training areas all over. I've fired thousands of rounds through it, blank and live. Any rifle and magazine has to be kept clean for it to function and the CSRG is no different. If you store 20 rounds in an M-16 magazine, you're in for a nasty surprise, too. The crude appearance of the finish is the reason it got such a bad reputation. As far as it overheating, you fire 300 rounds rapid from a Lewis gun and you're just going to burn out the rifling. (I own and shoot one of them, too.)And if it was "almost guaranteed to jam", how did they manage to get it to deliver that unrivalled level of firepower you mentioned? Make up your mind! I've read many period doughboy accounts that praise the Chauchat for its light weight and utility in flanking and taking out fixed machine gun positions. The American soldier, once he got used to its appearance and maintenance requirements, used it heavily and well. So let's hear it from an experience point of view. Tell me what you really know about the CSRG and not just from the other side of a glass case in a museum. By the way, it's pronounced "Show shat"

According to "Small Arms of the World" 10th Revised Edition (pp 112 & 113) the Lewis machine gun was invented by Samuel Neal McClean. Isaac N. Lewis was the promoter of this weapon and made improvements to its design and operation.
