I read about Thingol's "bravery" last night. Morgoth gets back to M/E and sets up camp in Angband. Some time goes by, the Sun and Moon get put into place and Morgoth decides it is time to send his bands of critters out to ravage the countryside.
Thingol puts up a good fight at first. In fact he routed one orc host, with the help of the dwarves of course. However the second host of orcs had gotten the best of the other elves (Teleri?).
So does Thingol race back to help the Teleri? NO! He runs back to his fortress and has his wife raise the mountains up around it so no one can get in. Nice guy to have watching your back.
And Jen wanted everyone to read Silmarillion? Hehehehe
