Continuing the rather off-topic issue of cavalry behaviour....

It's annoying when they charge into a Chevaux De Frieze or a square - and saying if you want to order them to do it they should is missing the issue.

Chevaux de frieze existed so cavalry couldnt approach that way - not so they would pile up dead on them.

The simple fact is that horses are not humans and they will NOT charge at long thick lines of pointy things. hence the Schiltrom formation for example (and like the square, great against cavalry, disastrous if the cavalry keep you in the formation while the longbowmen or successors kill you all)

As an example the (stupid) repeated mass-charges of the French Cavalry ordered by Marshal Ney at Waterloo - they swept up through and around the Allied positions - but for the most part just made good targets for the Infantry formed into squares.

When Napoleon wanted to do the right thing and make a combined attack to have the cavalry force the allied infantry into squares to be smashed by French Infanty columns - he couldn't do it, the horses were 'blown' by the stupid charges.

As for the LI - usually three lines deep, cannons interspersed between units - which brings up another totally nerfy thing - when the enemy got too close to the cannon they fired off their last grape/canister then legged it behind the infantry (or into the squares as at Waterloo) - they didn't engage in melee if they could possibly avoid it.

When the immediate danger passed they went back to their guns and got back on with their job, I have seen them get into melee then among the scrum - assuming any survive - I have to find them and get them to go back to the guns - bah humbug

As for manoeuvre - as has been said where at all possible Envelope the enemy from both flanks till they run away then micromanage your horse till they have killed as many as possible

On the upside, I haven't had CTD's lately - since choosing Shader 2 and turning off all cpu's except CPU1 on my quad-core
