Historic and technical information
Denomination :     M 220 Mle 1916 TR Schneider Origin :       ( Schneider)          

Historic context :

The Schneider Works in Le Creusot developed between 1914 a modern and complete artillery system for Russia. Just before the war outbreak, the talented company had the opportunity to demonstrate that experience and the quality of the related materials to have several of these weapons adopted in emergency (after some adaptations including the adaptation of the calibres to metric dimensions compatible with the existing ammunition standards) by the French army in desperate need of heavy artillery weapons.

Less numerous than the famous '155 C Mle 1915' coming from the same family, the 'Mortier Schneider de 9 pouces' (9 inches Scheider mortar) designed for Russia was transformed into the 'Mortier de 220 mm TR Mle 1915 Schneider and adopted by the French army as the winner of the January 1913 contest organized for the selection of a new modern siege and fortress weapon hanving the 220 mm calibre already present within the old de Bange system, and able to fire on its wheels the ammunitions of the old 1880 mortar, 40 such mortars were delivered to the army at the end of 1916 and arrived on the battlefield in March 1917.

A heavier model equipped with rubber wheelbands was then introduced with the 'Mortier de 220 mm TR Mle 1916 Schneider. The plants were long to produce this new weapon, so that it could only equip the batteries massively from 1918.

Although one can consider this weapon as a French answer to the brilliant 21cm German mortars, the very good ballistic properties of the French mortar against field fortifications were somehow compensated by a mediocre mobility because of its heavy weight, the need to transport it into 2 separate loads (barrel and carriage), and its difficult setup in position (2 hours needed).

The French army was aligning 376 such guns in May 1940.
