Mistake Made

[Arrowhead]

Use mercs and lay ambushes near roads.

[Count Belisarius]

Make peace with your non-civil-war neighbors, form alliances wherever possible, encourage your allies to attack your enemies, and maybe even give away a rebellious/nonproductive province or two to sweeten the deals. Concentrate your field armies (even town watchmen can be useful in a pinch if you have superiority in cavalry and a good general to keep them from breaking), trade space for time, hit your enemies hard, and keep moving, always moving. Above all ATTACK ATTACK ATTACK, BANZAI!!!!! This kind of impossible scenario is what makes RTW so much FUN (even with the bugs)!!!
