I just wonder, what happened to Annael? It is told in the Silmarillion that he was the leader of the Grey Elves who harboured Rian after Nirnaeth Arnoediad and then he became a foster father of her son Tuor. And then he tried to lead his people away from the Caves of Androth and to go to the Havens of Sirion. During that journey Tuor was taken captive by the Easterlings. But what about Annael? Was he killed? Or did he flee, and if so, did he finally reach the Havens of Sirion? What was his final fate? Is it possible that he could meet once more with Tuor after the fall of Gondolin?
I tried to find the answer to your question on the web. I did not have my books handy to look in them. I could not find anything on the web, so I went to the Tolkien Society and posed your question to them. I should have an answer in a day or so, and will let you know what they have to say. I will also continue to seach my books.
