Absolutely, Kat. I was hoping somebody would reach that conclusion. Imagine the amount of ammunition that would be required to cut a wire obstacle 1,000 yards long and 50 yards deep, not counting the stuff that was rewired each night. (The 50% zone for the 18-pounder was 30 yards at about 3000 yards range.)

There had to be a better way, but imagine how many bangalore torpedoes would be needed for a divisional attack with four battalions up, each with two companies up with two platoons up. And by 1917 infantry did not march forward like Waterloo, they used fire and movement behind an artillery barrage that could be 700 yards deep.

Mods, sorry for the hijack. I'm a gunner; that's what we do.
