Thought i would repost this tactic in this thread since it seems the most appropriate.
Hands down the most effective cavalry tactic i have ever used !
I got a complete wrap on the enemy, tried it on a large Fierdsvane and it worked so well it boggles the mind.
A foward wedge of your toughest cavalry, and a spread line of lancers up the rear. Send them in at the same time, order the wedge a waypoint behind the enemy so they charge straight through and split the formation then order them to charge, they will likely get surrounded quickly by a large force but this is good. The secondary wave will be close behind, so the heavy cavalry that were in the wedge will receive backup as quick as possible. Order the line to pass through the enemy, once the line has passed many will have stopped already and started combating the enemy. Order the line to charge once they have passed and the enemy force that is surrounding the initial wedge will be surrounded themselves, likely most knocked down in the process.
The beauty of this is that the tactic can be employed quickly with cavalry, so their cavalry wont have even left the formation before all your forces hit, and when the secondary wave hits the enemies attention will be completly on the wedge, so your line of heavy hitters can start striking at their backs and scattering the enemies attention everywhere.
If the formation is thin enough, the enemy will be split completely into 2 groups. I found Hero adventurers in the wedge especially effective because once they're in melee they will try to get away and use horse archery so are far less likely to die in the process.
* Moment before the charge
* Enemy formation split completly and quickly surrounded. Enemy cavalry doesn't even know what to do.
* Another battle, Fierdsvane shield wall completly split by wedge passing through, then flanked by lancers with their backs turned.
