Fighting enemies with air superiority is an absolute nightmare, as Abramo well knows. Venezia-oltre-il-Mare did effectively nothing, except defend the Caucasus and the Strait, before fresh supplies of modern fighters arrived from the American factories. But to fight enemies who can fly, when you have literally no air force, not so much as a flak gun improvised by turning a machinegun upwards, and your army seems unfamiliar with the entire concept... that is new to him.
Well, first things first. He cannot do without Regill, his liaison with the Hellknights; or Irabeth, who commands the paladin orders; or Galfrey, technically the head of the state fielding his army. Woljif is reported to have run into the night, which is bad if accurate, but it's also one of those wild rumours that fly around any war camp and are reported as "eyewitness accounts" by people who did not see anything of the sort; he will not accuse a comrade of such a thing until he has at least checked the obvious alternative hypothesis that they were captured by the gargoyles along with the others.
It is an error to allow the enemy to force your hand, it is an error to attack a place the enemy knows you must take... but needs must when the demons drive. The alternative is that his army breaks apart on the spot.
He will march on the Lost Chapel.
