Turn 19: November, 263 BC
The Romans stayed and fought at Henna, and Hanno defeated them! Whereas, the previous engagement at Messana was also a victory, it was a minor skirmish and I actually lost a lot more than the Romans because my army retreated. However, this was a more substantial engagement, with three rounds of combat (one stalemate and two victories), many casualties, and the Romans retreated taking additional hits from the retreat.
I gained 1 NM for each of the victories, so now I'm up to 89 and I gained 42 VPs. The battle was very evenly balanced as you can see from the power tooltip (in spite of the fact I had a 2:1 numerical advantage!). I'm glad to see that I can actually win even combat. My early experience when Hiero led the battles was that I was doomed, but this is looking more encouraging...
The trouble is that the Romans withdrew to Tauromentorium and I can't afford to attack them there as it would unlock Syracuse. I can't afford to attack Messana because the frontage situation is terrible and gives the Romans a huge advantage. So the Romans basically have a safe haven to regroup. Their cheap replacements mean they'll be back up to full-strength whereas I can't afford to get replacements, so I need to head back to Lilybauem and rotate more units.
As I mentioned, the longer term problem is that I'm already at Hanno's CP cap whereas the Romans can still merge their consular armies.
Lastly, I make another gift to Tanit, so I'll be able to go up to 91 NM next turn. I'm edging closer to 95 NM. And the Africa army is now unlocked, so if I really need to I can rotate those troops as well in Hanno's army to keep it at maximum strength.
