Drumfire: the sound of a massive WW1 artillery barrage

REUPLOAD
This is a very light attempt at making a somewhat realistic sound effect that conveys what World War One artillery barrages sounded like. No movie (exception maybe for the attack scene from Paths of Glory), sound effect, and certainly no video game, i have ever seen comes even close to representing the fury of thousands of guns turning an area into the moon. This is what the soldiers who fought at Verdun, Ypres and the Somme had to deal with for days on end; but i think this doesn't even come close. if it was fully realistic, you would only hear white noise, a constant crackling and rumbling that's more like the sound of the ocean, or being inside of an erupting volcano. That is exactly how many veterans put it.

Nobody would want to re-live that, not even as a videogame. The game Verdun is like uplifting slapstick comedy compared to the real thing. I mean, who would want to play a game where you die 50% of the time during the ten hour slog through corpse-mud-soup filled ditches that once were trenches, across a positively hellish landscape under permanent artillery fire, to the "front" (really a vaguely defined massive open-air mass grave whose geography and general appearance can only be described as Mordor); only to die 8 times out of 10 from an artillery shell, without ever seeing an enemy soldier, never mind shooting at one! No, really, if you were to make someone play a realistic WW1 game, he would never want to play it again after a few minutes.

This sound effect could also be accurate for supermassive Soviet artillery barrages during WW2 such as during the Battle of the Seelow Heights where they fired 500,000 shells and rockets in 30 minutes; the heaviest artillery bombardment in all of human history. Still; these barrages were spread over a much wider area, lasted for a short time, the frontlines moved and the troops were rotated; meaning you didn't have to endure this for weeks on end.

Painting is called "Hell", by George Leroux, an aptly-named nightmare of a painting depicting the battlefield of Verdun.

"In the course of the afternoon the firing increased to such a degree that single explosions were no longer audible. There was nothing but one terrific tornado of noise. From seven onward the square and the houses round were shelled at intervals of half a minute with fifteen-centimeter shells. There were many duds among them, which all the same made the houses rock. We sat all this while in our cellar, round a table, on armchairs covered in silk, with our heads propped on our hands, and counted the seconds between the explosions. Our jests became less frequent, till at last the foolhardiest of us fell silent, and at eight o'clock two direct hits brought down the next house.

From nine to ten the shelling was frantic. The earth rocked and the sky boiled like a gigantic cauldron.

Hundreds of heavy batteries were concentrated on and round Combles. Innumerable shells came howling and hurtling over us. Thick smoke, ominously fit up by Very lights, veiled everything. Head and ears ached violently, and we could only make ourselves understood by shouting a word at a time. The power of logical thought and the force of gravity seemed alike to be suspended. One had the sense of something as unescapable and as unconditionally fated as a catastrophe of nature. An N. C. 0. of No. 3 platoon went mad.

At ten this carnival of hell gradually calmed down and passed into a steady drum fire. It was still certainly impossible to distinguish one shell from another. " - Ernst Junger, "Storm of Steel"
