As far as the command structure actually used at Waterloo by the Emperor, that is another story. Here I have used only those that were available. I would have had Soult or Ney as commander of the left and drafted Davout in to command the right. There is little point in leaving arguably your best fighting commander at home minding the shop because if you lost, it was all over anyway.

As Berthier was dead, the post as Chief of Staff would go to Bailly de Monthyon. The only problem I can see here is that as only a General de Division he was subordinate in status (not rank) to both wing commanders who were Marshals. Bailly de Monthyon so long understudy to Berthier, who was a good teacher, was a natural successor since he had years of watching the master at work and would have known what was required of him. He would certainly have adopted Berthiers tried and trusted methods and as a result communications would have been very much better.

Marshal Louis-Gabriel Suchet, following his successes in Spain would have been a better choice than Grouchy. Instead of leaving him away from the main action as Commander of 7th Corps of Observation, really l'Armee des Alpes.

That was another tongue in cheek item really, which will hopefully draw response from far and wide. Poor old Grouchy seems to cop it everywhere, although in fairness he did have his strong points and indeed his supporters.
