The First World War was unique in that it was the first war in which more men were killed as a result of the projectiles rather than from disease; and it was artillery that did the lion's share of the killing. This article appeared during the early months of the war when the world was shocked to learn of the astounding losses due to advancements in artillery. There is an illustration of an unidentified German howitzer (more than likely a 1911 model 210mm) and an account of the roll that German gunnery played during the siege of Liege and Fort Loncin in particular.
"The one big surprise for the military experts thus far developed in the European war is the effectiveness of the heavy guns of the German field artillery. Never before have such terrible engines of annihilation been carried by an invading army as those used in the assault upon the forts at Liege."
