Well, you didn't really get the chance to, did you? Your ally's virtually dead, in large part because nobody helped them. Not even their ally.
We considered helping them, but had Nivemus helped Fontan we would have just been clobbered by Perdan/Westmoor/Caligus. Besides, when the war started, we were still around 4 regions short of finishing our expansion and had fewer nobles than we had now, and our infrastructure was weaker.
It would have been Nivemus and Fontan(combined maybe 30K CS, and Fontan couldn't sustain that original 20K so less from there on out) against the Central Alliance(around 60K CS). We would have been a token force and not much else.
