Question: When was the quick-firing field artillery piece adopted who's derivative was The Canon de 75 modele 1914 Schneider?
Context: The 12-pounder long gun was an intermediary calibre piece of artillery mounted on warships of the Age of sail.  They were used as main guns on the most typical frigates of the early 18th century, on the second deck of fourth-rate ships of the line, and on the upper decks or castles of 80-gun and 120-gun ships of the line.  Naval 12-pounders were similar to 12-pound Army guns in the Gribeauval system: the canon lourd de 12 Gribeauval, used as a siege weapon, and the canon de 12 Gribeauval, which was considered a heavy field artillery piece. The French 75 mm field gun was a quick-firing field artillery piece adopted in March 1898.  Its official French designation was: Matériel de 75mm Mle 1897.  It was commonly known as the French 75, simply the 75 and Soixante-Quinze (French for "seventy-five").  The French 75 was designed as an anti-personnel weapon system for delivering large volumes of time-fused shrapnel shells on enemy troops advancing in the open.  After 1915 and the onset of trench warfare, other types of battlefield missions demanding impact-detonated high-explosive shells prevailed.  By 1918 the 75s became the main agents of delivery for toxic gas shells.  The 75s also became widely used as truck mounted anti-aircraft artillery.  They were also the main armament of the Saint-Chamond tank in 1918. The Canon de 75 modèle 1922 Schneider was a field gun designed by Schneider in the early 1920s.  France didn't buy any as it had an enormous stock of surplus Canon de 75 modèle 1897 field guns on hand and it was offered for export.  Chamberlain and Gander claim that Finland bought some and used them during the Winter War, but this hasn't been confirmed by Finnish sources. The 78th Field Artillery Regiment is a field artillery regiment of the United States Army.  Initially activated on 1 July 1916, the 78th Field Artillery Battalion did not see action in World War I, but would later be reactivated at the start of World War II and participate in the campaigns for Algeria-French Morocco, Sicily, Normandy, Northern France, Ardennes-Alsace, Central Europe, and the Rhineland with the 2d Armored Division.  The 78th Artillery Battalion's six batteries were reorganized into separate battalions in 1957, with the 1st Battalion, 78th Field Artillery being the only remaining active unit of the 78th Field Artillery.  The 1st Battalion, 78th Field Artillery is assigned to the 428th Field Artillery Brigade, supporting the Fires Center of Excellence mission through the conduct of Initial Entry Training in order to provide the Army with combat ready Field Artillery Soldiers.  The 1st Battalion, 78th Field Artillery conducts Advanced Individual Training for the 13-series (Field Artillery) Military Occupational Specialties (MOS) of 13B (Cannon Crewmember), 13F (Joint Fire Support Specialist), 13J (Field Artillery Automated Tactical Data System Specialist), 13M (Multiple Launch Rocket System Crewmember), and 13R (Firefinder Radar Operator). The Canon de 75 modele 1914 Schneider was a French World War I piece of 75 mm artillery, designed and manufactured by Schneider et Cie in Le Creusot.  Similar to the earlier Canon de 75mm Modele 1912 Schneider and also a derivative of Canon de 75 modèle 1897, it featured a longer barrel and an extended firing range. The Canon de 8 Gribeauval or 8-pounder was a French cannon and part of the Gribeauval system developed by Jean Baptiste Vaquette de Gribeauval.  The Old French pound (French: "livre" ) was 1.079 English pounds, making the weight of shot about 8.6 English pounds.  The 8-pounder was the medium weight cannon of the French field artillery; the others were the light Canon de 4 Gribeauval and the heavy Canon de 12 Gribeauval.  Replacing the older Vallière system, the Gribeauval system was introduced in 1765 and the guns were first employed during the American Revolutionary War.  The most extensive use of Gribeauval guns was during the French Revolutionary Wars and the Napoleonic Wars.  The 8-pounder could be found in divisional reserves, advanced guards or army artillery reserves.  Emperor Napoleon began to phase out the 8-pounder by increasing the proportion of 12-pounders in his artillery.  The emperor began switching calibers to the handier 6-pounder piece, utilizing captured guns as well as newly designed French cannons.  The Year XI system began in 1803, but it only partly replaced the Gribeauval system which was not entirely suppressed until the Valée system was introduced in 1829. The Canon de 12 Gribeauval or 12-pounder was a French cannon and part of the system developed by Jean Baptiste Vaquette de Gribeauval.  There were 1.079 English pounds in the Old French pound (French: "livre" ), making the weight of shot nearly 13 English pounds.  The 12-pounder was the heaviest cannon in the French field artillery; the others were the light Canon de 4 Gribeauval and the medium Canon de 8 Gribeauval.  Superseding the previous Vallière system, the Gribeauval system was adopted in 1765 and its guns were first used during the American Revolutionary War.  The greatest use of Gribeauval guns came during the French Revolutionary Wars and the Napoleonic Wars.  During the latter wars, the 12-pounder was often employed in corps artillery reserves.  Because of their physical and psychological effect, Emperor Napoleon increased the number of 12-pounders in his artillery and fondly called the cannons his "belles filles" (beautiful daughters).  Gribeauval cannons fired canister shot for close-range work and round shot at more distant targets.  In 1803 the Year XI system was introduced, but it only partly replaced the Gribeauval system which was not completely replaced until the Valée system was set up in 1829. The Canon de 75 modele 1912 Schneider was a French World War I piece of 75 mm artillery, designed and manufactured by Schneider et Cie in Le Creusot.  It entered service with the French horse-mounted artillery in 1912 and a number were sold to the army of Serbia.  Until the end of the war, all guns in French service were replaced with the more successful and standardised Canon de 75 modèle 1897.  The remaining guns were then sold to Poland, where they were used in the Polish-Bolshevik War. The Canon de 240 L Modele 1884 started life as a coastal artillery piece for use in coastal fortifications.  However the events of 1914 dictated that it would soon see action inland as heavy field artillery and railway artillery during World War I. The Obusier de 6 pouces Gribeauval or 6-inch howitzer was a French artillery piece and part of a system established by Jean Baptiste Vaquette de Gribeauval.  The Old French inch (French: "pouce" ) was actually 1.066 English inches long so the weapon can accurately be described as a 6.4-inch howitzer.  The Gribeauval system included the 6-inch howitzer, the light Canon de 4 Gribeauval, medium Canon de 8 Gribeauval and the heavy Canon de 12 Gribeauval.  Superseding the older Vallière system, the Gribeauval system was introduced in 1765 and the guns were first used during the American Revolutionary War.  The most comprehensive employment of Gribeauval guns occurred during the French Revolutionary Wars and the Napoleonic Wars.  Two 6-inch howitzers were often added to four or six cannons to make up a battery of artillery in Napoleon's armies.  The 6-inch howitzer was capable of firing an exploding shell at long-range targets or a canister shot at close-range enemy personnel.  Starting in 1803, the Year XI system partly replaced the Gribeauval artillery, but it was not until 1829 that the Gribeauval system was wholly superseded by the Valée system.
