Item Description
Original Item: Only One Available. This is a fantastic rare French World War 58mm Trench Mortar known as the Crapouillot or "Little Toad". This example is dated 1917 meaning due it being post-1898 it is not legally considered an antique. Therefore, a hole the size of the bore has been made in the barrel with a bar inserted to obstruct loading rendering it inert and totally legal to own within the United States.
The Mortier de 58 mm type 2 or Mortier de 58 mm T N°2, also known as the Crapouillot or "little toad" from its appearance, was the standard French medium trench mortar of World War I.
A similar example can be found in the collection of the renown Australian War Memorial at this link.
French spigot mortar used by the French Army during the First World War. The original designs were conceived in February 1915 and put into production in April 1915. It could fire a finned 16kg projectile 600m, or a similarly finned 45 kg projectile 350m.
French 58 millimeter mortar designed to fire a finned projectile. The mortar is made from cast steel, and is smooth-bored and has a simple elevating mechanism built onto the carriage. The elevation is controlled using an horizontal handwheel mounted under the barrel. The barrel is mounted on a carriage, which consists of two cast iron cheeks, each of which has a slotted guide for elevation locking bolts.

The majority of military planners before the First World War were wedded to the concept of fighting an offensive war of rapid maneuver which before mechanization meant a focus on cavalry and light horse artillery firing shrapnel shells at formations of troops in the open. The problem facing the combatants was that their light field guns were designed for direct fire and only had limited angles of elevation and weren't capable of providing the high-angle indirect fire needed to deal with enemy troops in dug-in positions.
The simple expedient was to elevate the guns by having them fire from pits but the size and weight of the guns were excessive and pack animals couldn't move the guns in the trenches or across the shell-pocked quagmire of no man's land. What the theorists hadn't foreseen was that land mines, trenches, barbed wire, and machine guns would rob them of mobility and as the Western Front stagnated into trench warfare the light field guns that the combatants went to war with began to show their limitations.
Often defenders would wait out a preparatory artillery bombardment in reinforced dugouts and once the bombardment had lifted they would man their trenches and machine-gun nests in anticipation of an enemy attack across no man's land. Barbed wire was often used to channel attackers away from vulnerable areas of the defender's trenches and funnel attackers into predefined kill zones where overlapping fields of machine-gun fire could be brought to bear or to hold attackers at a safe distance to call in defensive artillery fire. The machine-gun nests could be constructed of sandbags, timber, corrugated metal, and concrete with overhead protection. For infantry advancing across no man's land, all they may see is a small horizontal opening at waist level, with just the top of the gun shield showing. Attacking infantry would have to close on these positions while under fire and destroy them with rifle fire, grenades, and flamethrowers.
The problem for the French Army was they lacked light, portable, simple, and inexpensive firepower that could be brought with them to overcome enemy machine gun nests and wire entanglements. Early on they experimented with crossbows, catapults, and slingshots to propel hand grenades with limited success. Unlike the Germans the French lacked portable mortars like the 7.58 cm Minenwerfer, 17 cm mittlerer Minenwerfer or 25 cm schwere Minenwerfer. The mortars that the French did have the Obusier de 155 mm C modèle 1881 and Mortier de 220 mm modèle 1880 were siege artillery designed to arm France's forts that were much heavier than their opponents and not designed to be mobile.[
History
In 1914, Commandant Duchêne of the Engineers (of the 33rd Corps belonging to X Army) began experimenting with a simple improvised tube mortar made from discarded Canon de 75 mle 1897 cases at the end of a pole. He found he was able to build a simple high-explosive fragmentation projectile that could be used as an anti-personnel weapon and to clear barbed wire entanglements. On November 7, 1914, Commandant Duchêne was sent to the Bourges pyrotechnics school by order of General Joseph Joffre to develop a mortar under the direction of General Dumézil, inspector of artillery studies and testing.
Mortier de 58 T N°1
The basic specification was for a light, mobile, and inexpensive mortar which could fire a 10 kg (22 lb) projectile to a range of 200 m (220 yd) using a smokeless powder propellant charge. The requirement also specified a weapon that could be produced from non-strategic materials, using simple production methods and produced by companies not currently engaged in war work.
The launcher was a simple pole 58 mm (2.3 in) in diameter with a round weighted base at one end and a hollow cup that held the propellant charge at the other. An adjustable sleeve was attached to the pole that connected to a crescent-shaped elevation mechanism with holes for elevation. The elevation mechanism then fit into the center of an A-shaped bi-pod and elevation was set by pushing a bolt through the elevation hole. The 60 g (2.1 oz) propellant charge was then inserted in the muzzle and the projectile slid onto the end of the launch tube. The mortar was fired by pulling on a lanyard which was attached to a friction igniter embedded in the propellant.
The first 70 mortars were delivered in mid-January 1915 to troops in the Argonne region for testing. The tests were considered successful and General Joffre ordered another 110 mortars and the production of 4,000 projectiles a day. However, the tests revealed that the launcher was unstable and had a tendency to tip over when pulling on the firing lanyard. The launcher often fell over after being fired and had to be re-aimed between shots which limited its rate of fire. The troops also requested heavier projectiles with larger explosive charges to deal with enemy troops in dug-in positions and these factors led to the Mortier de 58 T N°1 being replaced in 1916.
Mortier de 58 T N°1 bis and Mortier de 58 T N°2
To address deficiencies in the design of the Mortier de 58 T N°1 Commandant Duchêne continued to work on the design of two new mortars concurrently with completely different bases. Where the N°1 was tall, thin, and top-heavy the N°1 bis and N°2 launchers were short, had a broad footprint, and low center of gravity. The long launch tube wasn't needed to elevate the projectiles past the lip of the trench so a shorter and sturdier launch tube was used instead. Both designs were much more stable which led to a higher rate of fire because they didn't need as much setup time between shots. Their short and fat appearance earned them the nickname "little toads".
The Mortier de 58 T N°1 bis weighed 181 kg (399 lb) and could fire the same projectiles as the Mortier de 58 T N°1 to 450 m (490 yd) at +45°. However, the projectiles were considered too light and the Mortier de 58 T N°1 bis were in turn replaced by the Mortier de 58 T N°2. The advantage of the Mortier de 58 T N°2 was that it could fire new heavier projectiles of similar design to a greater range but it weighed 410 kg (900 lb) so it wasn't as mobile but still light enough that it could be lifted by the crew and placed on a cart and towed by pack animals. The N°2 became one of the most widely used French mortars of the First World War with 276 operational in June 1915, 779 in March 1916, 1,268 in May 1917, 1,766 in January 1918, and 1,158 in November 1918.
Both the Mortier de 58 T N°2 and Mortier de 58 T N°1 bis were used by the Italian Army who gave the Mortier de 58 T N°2 the designation Bombarda da 58 A and the Mortier de 58 T N°1 bis was designated Bombarda da 58 B. Approximately 1,000 of both types were used by the Italian Army.[8]
Projectiles
3 types of bomb were available:
Light L.S. bomb - 18 kg (40 lb), containing 5.35 kg (11.8 lb) of explosive. 6 wings, hollow plugged tail.
Heavy D.L.S. bomb - 35 kg (77 lb), containing 10 kg (22 lb) of explosive. 6 wings, hollow plugged tail.
Medium A.L.S bomb - 20 kg (44 lb), containing 6.4 kg (14 lb) of explosive. 3 wings, unlike the other 2 it has a hollow tail which contained the propellant charge, placing thrust closer to center of gravity and increasing range and accuracy. Not yet in common use as at March 1918.
Examples of capabilities:
To destroy a 3 m (3.3 yd) x 3 m (3.3 yd) blockhouse, 60-80 D.L.S. bombs or 100-150 L.S. bombs were required.
To cut a passage through barbed wire defenses 40 m (44 yd) wide x 30 m (33 yd) deep, 120 D.L.S. bombs or 200 L.S. bombs were required.
