The Schneider Mle1914 “mortar” ’s development started for the 1912 trials of Otchakoff, and with the gun being subsequently adopted by the Russian army. As WW1 started, France was lacking -among other things- heavy siege guns- as they were still waiting for their own 1913 order to be delivered. Russia and France instead agreed to share the current 16 produced units between them. At the end of the war, 165 were in French service, including 25 that were being fitted on tracked chassis.
