They will do their best to get that to him as well!
The losses aren't unusually bad, considering the circumstances, but that still translates to quite a number of casualties. Nenio is dead, albeit unlikely to stay that way for long; considering the Crusade's shortage of arcane casters, she's easily worth a Raise. A pair of elite paladin-archers, one of whom accompanied him on the trip to rescue the Hellknights, are likewise dead and expected to merit a Raise. But by far the majority of the dead will stay that way: the Bless-sorcerer he traded for, the person who wanted to know if it was an illegal order to order someone to join a paladin order, one of the Sarenrite clerics he got along well with, two of the lower-ranking embezzlers, and (of course) many others who had never particularly risen to his individual attention.
(They have the budget for the Raises, in the sense that the diamonds are already bought and paid for. Bringing back the dead costs more than a headband, more than a belt, but some people are useful enough to the war effort to be worth it, even with Mendev's ongoing budgetary woes.)
Materiel losses are thus far sustainable. They're going through cold iron arrows quickly, of course, but Garms was able to take Blai's advice about finding Chelish suppliers, and they're not in any danger of running short. They're having, if anything, the opposite problem with the demonsbane arrows; their archers tend to be reluctant to shoot them even in circumstances where it would be warranted. They have recovered the following items from the demons, most of which are pretty unimpressive but a few of which might be worthwhile (...probably due to being stolen from the Worldwound's defenders in years past, or at the very least it's not like they've got a better explanation for how the demons ended up with magical items).
