And last night I suddenly realised something that's been nagging me. I knew that the scene in TDTCB where Cnaiur is lying in the mud on the bank of the river Kiyuth and pretending to be dead reminded me of something. And then I realised - there's a similar scene in Karl E. Wagner's "Dark Crusade", where Jarvo, the general of a beaten army, is lying in the mud and his enemies think he's dead.
