Gaul

[Empedocles]

Ok, I'll edit this latter, this is my early version of the story.
Raise two armies and send them south to conquer those rebel provinces that separate your provinces!
Now that you have a continued empire, build forts at the fords of the Po River in north italy so you can keep romans at bay! They are soy difficult!! you should ally with all the roman factions so the Julli see you with better eyes (they will attack you in the future)
After you conquered the mid-france rebels and secured your south frontier, move north because the brits are going to attack you almost from the first time.
Move a diplomat east to ally with germany and try to make them attack the Brits.
Fighting the Brits it's not a big issue because their armies are made of warbands mainly. But you should build a navy in the english channel to keep them on their island.
After you have maintaned your income then you should hire some mercenaries (specially cavalry) and take the fight to their own lands.
They have a huge army near my northern city and started to siege it, but when I took London they retreated and know seems to have lost their path.

Get used to use Warbands, you will not have another unit for many years and they are good fighters if usen properly. Try yo upgrade their armour and weapons with blacksmith and shrines in Milan and Alesia

PS: one tip: raise mercenaries units and use them to face the enemy while your warbands flank them. After the battle you may want to disband them cause your financial situation is bad.
