Turgon's sword

[Afrodal Fenyar]

Yes. But strangely, Gondolin was never really involved in any of the wars. It was carefully hidden and guarded secret. Its people never really fought until the armies of Morgoth came over the Encircling Mountains. Even when the city was invaded and being destroyed, Turgon himself never fought. He climbed to the top of his tower, with Glamdring, and watched. The tower was evetually thrown down whena dragon hit it.

Well, 10 000 soldiers from Gondolin fought in Nirnaeth Arnoediad, so it was involved in one war before it's ruin.

And is there actually any other writing where the tale of the Fall of Gondolin is told completely than The Book of Lost Tales(I think you took from it the fact that Turgon just sit in his Tower)? After all, Lost Tales must not be taken completely seriously, Tolkien changed some things many times. Though Turgon is said to have fallen with his Tower also on the Silmarillion..
