How many test 've you made (it's random seed) and it's possible, that Mav set 1-2 units more there. I 've won also, but there are no units to defend the town after capturing. And you need the cross or?
So long Mav builds no cats we should wait of the 1. reinforcement. A few cats more, make the injuries of our troops not so bad.
the 1. reinforcement has 1 cross (now build in Arc), 1 mace (in moment at old army point) and 2 cats, the 2 has 2 HA, Juno, a mace from Vega and cats (we 've 5 cats, 1 pike); in Vega and Arc we can whip to get big overlay and 2 units more for the 2. reinforcement (Nobody and EI 2).
btw
In the test I gave the units ** additional, for fortifying.
