Need some information about Mantinea 207 BCE

[hoplite14gr]

After beating the Phokians he "broke all their weapons".
The Phokians were mainly well equiped peltasts.
They appear as such later in Chaeronea and at the sack of Thebes by Alexander. Which begs the question: what weapons Philip broke?

By that time Greeks knew the gastrafetes and Phokians with the delphic money hired lots of mercenaries. Assuming they had artillery it might have been an enlarged gastrafetes cabable of throwing stones but not the size of Later hellenistic artillery. Just a thought.

Kind regards
