River crossing in Beleriand?
There's a whole myriad of rivers and streams in Beleriand .Is there any good map that includes all the crossings?
How do you get from Tol Sirion to Eglarest for instance? (Let's assume this is before Nargothrond build their bridge). You'd need to cross the Narog, the Ginglith and the Nenning (Edit: I guess you could do that at Eglarest though). Where are the logical places to do that?
On most Maps you have the ford of Brithiach, and the crossings of Teiglin, both close to Brethil. These appear to the main passage that a larger force can take to get down into Talath Dirnen. Where do you go after that? Do you have to find some way over the Narog and then go all the way north to the Nuath around Ginglith?
Morgoth send forces against the Havens two times. First time is arond the time of the First Battle of Beleriand. It's then said they went west in the plains between Sirion and Narog they plundered far and wide, and it's to be understood I guess that from there, they somehow crossed over Ginglith to reach the Sea, since, the orc-host in the west was victorious and had driven Cirdan to the rim of the Sea.
The other time is after the Nirnaeth. At that time they are said to have passed south through Hithlum and Nevrast. (There's the question how that was possible also, but it belong perhaps not to this topic.)
So how do they do it the first time? Do they have to head north-west after Teiglin, and across near the pools of Ivrin? Then along the southern feet of the Ered Wethrin, westwards, and then south between Nenning and Brithon?
Then there is the Battle of Tumhalad. It's said in the Children of Hurin that Orcs assualt Brethil, seeking to secure the Crossings of Teiglin for their further advance. So I'm guessing that's the way they take down to Talath Dirnen.
Also though, Glaurung came into the north vales of Sirion under the shadows of Ered Wethrin he defiled the Eithel Ivrin and thence passed into the realm of Nargothrond and burned the Talath Dirnen. Glaurung perhaps is large enough to cross most rivers without a bridge?
So does he pass down near the Ered Wethrin, while his troops head over to the crossings of Teiglin? Or does he have troops with him on the more western path? They'd have to cross several streams, including Lithir, Malduin, Glithui and Teiglin up north.
There are known to be passes over the Ered Wethrin, near Lithir and Glithui (These are used by Hurin and Turin), but I don't know if those passes emerge on the north or south side of their respective stream? Also they wouldn't help someone traveling east of the mountains going southwards. Are these streams smaller and therefore easier to cross?
After battle starts the Elves are driven back to the field of Tumhalad, so I assume this means they're driven across the Narog somewhere? They are then penned between the Narog and Ginglith, suggesting there was no way across the Ginglith for them? There seems to be a way across for Turin though, since he speeds back to Nargothrond.
There's also the stream Rivil, which I assume can be crossed somewhere since there are mentions of Orc hosts coming up from South being driven into the fens of Serech. Or do they cross the Sirion near Tol Sirion, and then head north under the feet of the Ered Wethrin, since Celegorm is coming down on them from Eithel Sirion?
