"Show us that it wasn't a war of attrition, with men being forced over the top at gunpoint and battle police there to execute them if they were too slow or decided not to go."

Come on then Jim give us substantive evidence of what you say there ever happening - no long rambling vast diatribes of class war crap just one single example from a conflict that lasted 4 years 3 months and 1 week - Just one.

But just to visualise it:

There are roughly 1,000 men in a battalion (10 Companies of roughly 100 men)

You have the Reserve, or "Stay Behind" Company so roughly 900 men armed to the teeth are going to be "forced" over the top - by whom?? - Ah by the "Battle Police" - Who are? - The "Stay Behind" Company possibly? In which case when it comes to arms they would find themselves outnumbered 9 to 1 (So they aren't going to force anybody it would be them that gets slaughtered pdq) By another Battalion brought in just to "force" the "attacking battalion" over the top? In which case it would be 1 to 1. Possibly by two or three Battalions in order to give them forcing the others over the top a bit of an edge? Improve their odds of survival? (Getting awfully crowded in that trench now isn't it?) Are you starting to see how ridiculous the whole idea is?

By the way who judges what is quick enough Christmas? Or is it entirely up to the individual? And all this because some ex-Docker came out this crap to you telling you things he thought you wanted to hear between sobs interspersed in the narrative for effect.

Prediction: Jim Carroll will not come up with a real live example of this ever happening, because he can't - it never did happen.
