a good description of uncertainties when you don't know what's going on elsewhere (and you don't have an escape route).
I was really struck, when I thought about it, by how distant the siege and the battle for the Pelennor might have felt from the Houses and the Citadel, if the geography of MT really is as I (and to some extent PJ) have always pictured it. It clearly takes ages to trudge up from the First Circle to the Sixth, especially the way the gates are offset so you can't go straight up the hill. So I imagine the only messengers going to and fro during the siege would have been the strictly essential, strategic ones (to Denethor, later Gandalf and Imrahil, and possibly also to the Warden of the Houses, but not to all and sundry).
Great fun for fanfic authors, as we can play dramatic-irony games with who finds out what about the state of play elsewhere and when...
Good luck writing! I'm looking forward to the next chapter.
Thank you! So am I - I know what happens, RL just has to butt out of the way long enough to let me get a writing head on...
