Query - infantry in column surrounding cavalry

[phoenix]

Can anyone more experienced than I help here - I'm wondering about the desirability of house rules to cover this.

It's possible to surround, isolate and trap even quite strong cavalry formations with infantry columns. Say a cavalry stack of around 400 horse surrounded by infantry in column, each infantry unit around 700 strong. Once cut-off the cavalry can't really do much against 700 men in column and even with limited fire from the columns surrounding them they quickly become disordered, isolated etc. It can take a long time to eliminate them with ONLY column fire, but it's possible.

Substitute a strong cavalry stack for one of the surrounding infantry stacks and then you can melee into the trapped cavalry stack with your own cavalry stack and eliminate it much quicker, and meanwhile, because of the column infantry pinning it, it can't escape.

I've never myself done this because it seems ahistorical to me - to surround cavalry with infantry in column. But it's happened to me a few times in H2H play. I don't mind cavalry surrounding cavalry - but infantry? Did it happen? Wouldn't infantry in column have a little more respect for a mass of 400 or so horse? Does anyone think this is ok - to use column infantry this way - or should there be some kind of house rule to encourage respect for the cavalry?  

Thanks.
