Since we get quite often the question - How to defeat Pyrrhos as the romans? I decided to share my experiences on this matter The tactics shown bellow have been tested numerous times and work best on medium difficulty. If you have fatigue turned on this might help as well.
So step 1 - Move Decius Mus and his army to this place west of Pyrrhos
Step 2 deploy your troops in a single long line. Set all hastati and principes to Fire at will - ON. Deploy the velites on your right flank and set skirmish mode and fire at will to OFF
When the enemy approaches he will be softened by the pila shower from your regulars. I usually put the slingers on the left flank where they first take care of the cavalry unit and then choose their targets as they will. your only cause of worries is that the velites might decide that they like animals and start throwing spears at the enemy infantry. This could be a problem with your thin red line but happens rarely.
When the elephants and the enemy left flank are gone, wheel your free troops and hit the phalanx. Soon they will start to rout, especially if Pyrrhos gets in trouble.
This time he was killed by a stone, sometimes he gets a javelin, others gladius.. Then just chase them like goats. Wait it's a barbarian speech. Well just chase them down till they are all dead and that's the step number 3.
Unfortunatelly this time the skirmishers didn't kill all elephants with javelins and had to chase them while the beats were running amock. This is the reason for the heavier than normal casualties among the velites and some spearmen.
And then it's all over.
Right after the fisrt battle you get attacked by a second army, which is a walk in the park compared to the first and gets easilly defeated with the same tactics.
What are your experiences with this nice fellow?
