750 (0): This looks grim. Agedincum is doomed if the French choose to move in that direction, and Verulamium is at great risk too.
I whip Verulamium's walls, as suggested.
More foul RNG luck. The Arabs go four for four attacking Verulamium and take the city, though three of their four archers are regulars and all their attacks are cross-river (0-4).
730 (1): I evacuate Agedincum, which we can't possibly hold against the eight adjacent French units.
The French auto-raze Agedincum, and ride down an archer attempting to escape (0-5).
Alesia walls --> spearman.
710 (2): Entremont walls --> spearman.
690 (3): We try to found a town in the northwest and get the "too many cities" message. So we're stuck with the six cities we have, and the situation looks hopeless, though I'll play out the round.
670 (4): Lugdunum walls --> spearman.
650 (5): We're able to shoot down a French horseman outside Richborough (1-5).
We abandon Second Chance so as to found Bad Times on a better site in the northwest.
630 (6): Two French horsemen attack Lugdunum and retreat.
North Town barracks --> spearman.
610 (7): With the French now rather strung out between Entremont and Lugdunum, we're finally able to counterattack, killing three horsemen and a warrior (5-5).
We slay a horseman and lose a spearman as the French attack around Lugdunum (6-6).
590 (8): After several turns of quiescence, the Arabs appear in great strength in the north.
570 (9): Sixteen Arabian archers close in on North Town.
550 (10): We slay two French archers outside Lugdunum (8-6).
Two elite victories didn't produce a Great Leader this round.
