A Continuous Roar

We heard the guns start up, and we knew this was going to happen, I understand there's 2200 guns firing, that's everything from anti-aircraft guns to the heavy's and so on. And you hear the guns start off then you hear the shells come over, and they whistle different sounds for different shells, different noises and so on. You got so you pretty well pick out what was coming. The German shells had a different noise too. Like the 88's they come in with "zip-bam!" They were very fast, where as the other ones there whistle as they come in you know. And if you got like a twenty-five pounder you hear just a slow whistle coming over, you got into say, a 55 it was a maybe a bit faster whistle, it was a bigger projectile. And the guys who cleared out Calais, the coastal guns there said that they turned the guns onto them like that, and they fired and said it sounded like a freight train coming through a tunnel when it come through the air. I never saw that. But you get the noise you can hear the guns firing, you can hear the shells going over you, you hear them explode. And after they got going it was just continuous roar you know. And I don't say you could see the shells but you could feel them going over like you know, there was air motion and so on. In fact on a twenty-five pounder, I know if your standing about twenty-five, thirty feet from the muzzle look out, but 20 feet past the muzzle you can see that projectile taking off. Heading for nine miles away they went that far. But you can see the projectiles when they take, first take off. I guess it's the same with the bigger guns too, I don't know. But it was an awful noise, just shook, everything shook, you know, vibrations and so on.
