You charge your opponent!
6*
His horse rather easily continues galloping after your lance skewers the knight and sends him to the ground.
The battle, of course, continues - he was a minor man with big ego and definitely bigger confidence values.
5*
Your footsoldiers continue to press against the enemy forces till they break like a dam breaks under the constant pressure of water it tries to stop. But the Luthians do not surrender even if most of their mercenaries are now gone.
5*
Still, it only prolongs the battle and as the sun slowly moves past its zenith, the battle is resolved.
You have won against the Luthian Alliance's possibly biggest army so far!
By the next morning, your scouts nad horsemen return, bearing captives and boasts of their pursuits, plus reports from the countryside.
The remnants of Luthian forces have fled east and then north, finding safe haven in Luathbas. No one decided to fly and strengthen the garrison of the southern cities. As officers gather for a meal, you consider your options...
A) The best course of action would be to send some men to besiege Luathbas while the majority under your command goes 'diplomacize' the lesser cities into submission.
B) We should rest and recuperate while riders go south and north to ask for reinforcements and new recruits, respectively!
C) Such a big, victorious battle should be complimented by a big, victorious siege - to Luathbas!
