Uh no. Caligus didn't attack the city.
Sirion attacked Fontan city and looted it some times, but never damaging it too seriously. The city became seriously threatened once Sirion secured Karbala.
So with Sirion thinking about their next move after Karbala, Caligus declared war on Fontan, took over An Najaf (if that's the name), successfully breached Fontan city but then found itself with too few men to pull a takeover through, because Westmoor was in the meantime attacking Viseu - key region for Caligus - backed by Fontan's remaining army and there had been a rather poor coordination with Sirion's armies at that moment.
Fontan never really recovered from that, they RTO'd An Najaf but weren't able to stabilise it, with Sirion regularly roaming the Viseu/Oporto area, and neither were they able to garrison Fontan city decently again with Sirion making sure to clean the militia every time it appeared (Sirion was in control of Karbala at that time, not firmly but still had it).
The conclusion is that Sirion took over Negev and Fontan city, handing the latter over to Caligus, too busy on the southern front to claim the city on its own.
I don't think that caligus' attack broke Fontan's back, given that Sirion already controlled Karbala and vastly outnumbered Fontan already back then, but it certainly sped up incredibly their demise, adding a considerable amount of gold to Caligus' income as a consequence.
And to those who said Ibladesh should have tried to overpass Caligus in his relations with Sirion: Caligus saved Sirion's ass by declaring war on Perdan with unquestionable timing (the nice loophole in the treaty, Indirik you should remember that
). Ibladesh was rather friendly, but never did or thought about doing something vaguely similar. They bought some food from us, that's all. There was no match there.
