what is your favorite tactic on the battlefield?

well,if you are a horse archer,it'sa low possibility

But if you are a swordsmen, then the possibility is very great.

But swordsmen wouldn't run away, so let us say you are a very barbarian-type guy, like with a wooden shield, an axe and a narrow leather jacket.

I, myself would preferr an all-out charge with all the men who could be in every contition except against longbnows. If there would be longbows then i'd just not attack.

I see longbows as being the predecessor to the standard form of attack for western armies: massed infantry equipped with missile weaponry.

But to answer the question I like the entire structure of the Roman attack. Testudo formation to resist missiles, a well drilled and disciplined volley of pila to soften up the enemy completed with the man to man contest complemented by the tactical mobility afforded by manipular organisation. It was a thousand years before that type of discipline, imagination, sophistication and battlefield nerve re-emerged.
