This is basically why Kale didn't bring it up to anyone: he just previously sent out urgent "Come to our aid against Asylon!" and when we learned Aurvandil was coming (only a few days prior to their landing) it was way to late to get help and any aid that did come would arrive weeks after they were sitting back at home in Aurvandil.
My char knew Aurvandil was comming, and I am pretty sure he told several Terranese nobles, in his "strange" attempt to save lives.
