Hi

Just to add to what Ironside wrote, there's a decent (but concise) description of Napoleon's employment of 'the strategy of the central position', with an illustration in the form of the Waterloo campaign, here: http://en.wikipedia.org/wiki/Military_strategy.

If you're up for some serious reading in this aspect of military strategy get a copy of 'Napoleon At Bay, 1814' by F. Loraine Petre. Talk about having your back against a wall and putting up a fight! IMHO this was Boney at his finest.

As for MTW battles, I rarely split my forces until late in the game when I'm (typically) waltzing around with +4 weapon and armour upgrades and hence confident my lads can beat the sh!t out of anything the AI can engage them with. Otherwise I find that, because I'm too slow at jumping from group to group, I sustain much higher casualties than I ought to. Which really annoys me.

The one exception to the above is in the use of skirmish-capable cav. I'll often create, say, a two unit detachment of HAs or similar and tell them to harass one of the AI's flank units, in the hope (regularly fulfilled) that the AI will send one or more units chasing after my boys, so (over)extending and/or disordering his line.

Best regards
Victor
