The Roman cav charges into the Gauls whilst the legions continue to advance. The velites take the wood.
Even though it may have been to the advantage of the Romans to delay the mounted clash, in the rules you only cause casualties in your turn, so charging in gives you the first swing so must usually be considered to be a good idea.
On this basis the Carthaginian foot look to get stuck in. Due to the lines being at a slight angle, only the Spanish are in charge range with the Gauls and Libyans closing up.
In response the Romans get well stuck in - fighting is now general along the line.
Apart from the skirmishers who are shooting at each other. As the velites are in cover they only take half hits however - which leads me to the decision that my slingers will soon draw daggers and charge in.
With their first charge advantage the Romans mounted rout the Gauls. Units stay on the table with no ill effects until they reach 15 hits - when they are removed. This is not so bad for Carthage however as the Roman cav is badly worn and facing fresh enemy reserves.
And the Spanish charge in! As long as we can win one of the fights in the centre to draw the attention of the Triarii we should be able to collapse the Romans from the flank - all very Hannibal.
A few turns later - the exact same picture. Heavy foot fights do take several turns to resolve. As all units were committed - apart from the Triarii, who were waiting for something to happen there were no decisions take take here, we just took turns rolling dice. Which was however somewhat exciting, looking to see who would get the breakthrough.
And here we have it, the mounted Spanish hack down the Roman cav and start dreaming of Roman flanks!
Not for long however, as the Triarii do exactly what reserves are for and cover the gap. Still, no worries, win the first fight in the middle and the day would soon be mine.
Lose two units in the same turn however and it seems the only thing that would be mine is the pointy end of a Roman sword.
The Spanish, not wanting to throw themselves onto the spears of a fresh unit of Triarii pull back.
With the Romans advancing against them and also putting pressure on the flank of the gallic foot.
There are no rules for what constituted a flank charge but I ruled that it would need to start behind the target units flank. This is a standard ancients rules idea and seemed reasonable to me. So the legion just moved into a position to deliver the coup de grace.
Which was not needed as the Gauls went down without the help of a flank charge.
With the writing on the wall the Spanish Cav thought they would try to take down the battered legion before it was game over.
