[Legate of Amon Lanc]

Well, it probably also took them a while to get to that place first, and also, maybe after an exhausting "battle of wills" and other stuff (trying to figure out what is happening, what is the forest doing, and what is the general situation since I've just returned from the dead a couple of days ago) Gandalf wasn't so keen to rightaway go and pursue some random Orc warband (of which there might likely have been more around, e.g. some random wood-gatherers or scouts).

Yes, that was the one I meant. Thanks for providing that.

And, yes, it's true that Fangorn is quite big, 100 miles from east to west and even more north-south: as big as the whole Shire, and nearly the size of all of Mirkwood south of the Narrows. It's a bit like saying "They were both in Denmark, surely they must have seen each other."

And yes, basically that was what I had in mind. We tend to see Fangorn as "oh, one forest, like the one near my house, where I take a walk for half an hour every afternoon". But Fangorn was essentially the size of a whole (smaller) country.

And Inzil's point is also quite a good observation, I'd say.
