"The object of the great proportion of artillery the Germans employ is to beat down the resistance of their enemy by a concentrated and prolonged fire, and to shatter their nerve with high explosives before the infantry attack is launched. They seem to have relied on doing this with us; but they have not done so, though it has taken them several costly experiments to discover this fact. From the statements of prisoners, indeed, it appears that they have been greatly disappointed by the moral effect produced by their heavy guns, which, despite the actual losses inflicted, has not been at all commensurate with the colossal expenditure of ammunition which has really been wasted. By this it is not implied that their artillery fire is not good. It is more than good; it is excellent. But the British soldier is a difficult person to impress or depress, even by immense shells filled with high explosives which detonate with terrific violence and form craters large enough to act as graves for five horses. The German howitzer shells are 8 to 9 inches in caliber, and on impact they send up columns of greasy black smoke. On account of this they are irreverently dubbed 'Coal-boxes,' 'Black Marias,' or 'Jack Johnsons' by the soldiers. Men who take things in this spirit, are, it seems, likely to throw out the calculations based on the loss of _moral_ so carefully framed by the German military philosophers." Every word of this admirable official message is borne out by the men's own version of their experiences of artillery fire. "At first the din is terrific, and you feel as if your ears would burst and the teeth fall out of your head," writes one of the West Kents, "but, of course, you can get used to anything, and our artillerymen give them a bit of hell back, I can tell you." "The sensation of finding myself among screaming shells was all new to me," says Corporal Butlin, Lancashire Fusiliers, "but after the first terrible moments, which were enough to unnerve anybody, I became used to the situation. Afterwards the din had no effect upon me." And describing an artillery duel a gunner declares: "It was butcher's work. We just rained shells on the Germans until we were deaf and choking. I don't think a gun on their position could have sold for old iron after we had finished, and the German gunners would be just odd pieces of clothing and bits of accouterment. It seems 'swanky' to say so, but once you get over the first shock you go on chewing biscuits and tobacco when the shells are bursting all round. You don't seem to mind it any more than smoking in a hailstorm."
