Depending on the sources, between 45 or 53 millions shell were fired for the battle of Verdun (it lasted 10 months). My great grandfather was wounded there and subsequently died from his wounds. I still have his medals. "The battle lasted for 302 days, the longest and one of the most costly in human history. In 2000, Hannes Heer and Klaus Naumann calculated that the French suffered 377,231 casualties and the Germans 337,000, a total of 714,231, an average of 70,000 a month. In 2014, William Philpott wrote of 976,000 casualties in 1916 and 1,250,000 in the vicinity during the war. In France, the battle came to symbolise the determination of the French Army and the destructiveness of the war." https://en.wikipedia.org/wiki/Battle_of_Verdun https://en.wikipedia.org/wiki/Battle_of_Verdun
