You're not wrong. In fact it was well known by everyone in the Colt Officers Mess that it was not a burner. Without specific orders it would never have been touched. C'est la vie.
In fairness he may not have specifically been aware that the JPs were picking up the tab since I can't be sure anyone ever told him that it needed paying for. However, the burning was preceeded by a very obvious confrontation between said VSO and OC Admin witnessed by many so there should never have been any doubt who had called for the bottle of Brandy and matches.
