I read a fascinating report on trench warfare that the shells being used to bombard the trenches just weren’t effective like the entente believed them to be. Supposedly, the shells couldn’t penetrate far enough to do that much damage, thus the huge bombardments, like the one before the Marne, didn’t do what they were supposed to have. So that when the infantry went over the top at positions that had supposedly been “softened up” they were really charging into full strength defenses.

One of the tactics the Germans took to using was to “abandon” the forward positions during bombardments, and pull back out of range. Thus, the artillery ended up falling on noone, after the initial first few minutes. After the artillery stopped, the Germans would then rush back up front (into the handy new shell holes) to beat off an expected attack.
The Allies got wise to this, and would do bombardments in “bursts”, trying to catch the Germans coming back forward, or do attacks without artillery prep, and so forth. None of that really helped in solving the problems of overcoming a fortified defense… at least, not on it’s own.
Smaller unit tactics was found to be the key.
The generals (generally) were all tied up into thinking in terms of Division/Corp/Army, especially when they were put in command of a million men.
Since they honestly could not think of why their meticulus planning failed (with artillery timetables, jump off times, supply levels looked after, paths of advance for battalions all laid out), they tended to blame the grunts. Not enough fighting spirit, or lack of ammo, the weather, lack of reserves, whatever.
“Can’t be my plan. I have gone over it for months. I accounted for every conceivable detail. Must be some other fault not in my control.”
