This is a completely different kettle of fish.
This a staged event in front of a Brigadier inspecting.
Then all of them refuse charges and request CM's then plead guilty. So as the Brigadier was a witness he couldn't have anything to do with the board and neither could anyone else in the regiment. So its a complete airing of the regiments dirty washing to division level. Isn't there a number of CM's before a regiment is deemed to have a discipline problem and Division then has to take an active role.
This is taking on the command chain up to Major-General level and to be quite honest winning. It might very well mean that the regiment is split up one division worth of men getting sent north and the other south to get split up.
That's planning way way above your squaddies pay scale and knowledge.
What's happen is that 16 men have taken on a regiment and possibly destroyed it. They didn't care if they got chucked out without pension. The only thing they could have done worse was if the Duke of York was present.
What on earth did the Brigadier do when it happened? Did he step forward and deal with it or did he turn his back and walk away. If he walked away that's him finished as well.
