Query - infantry in column surrounding cavalry

[agmoss99]

It's a difficult one.

Any house rule can be willfully misinterpreted. So saying something like x amount of cavalry cannot be surrounded except by y numbers of men per column is problematic. I doubt columns would advance on cavalry, at least from the front. So it is rather gamey to do it although I think most folks do. It's even more annoying if the cavalry Routs and with Isolation ON, can all be bagged before help arrives. Once trapped they are pretty lame ducks so charging forward without support is not advised.
I think you just have to accept that without pages of house rules, it's a game and not a historical simulation - and thus it's a case of 'do unto others - but do it to them first'.
