Ruin of Doriath - Final Part

[Maédhros]

I will try and make my point again.

First, we have in the Quenta that for a brief time, the place where the battle took place and where the treasure was drowned was the same River. (Ascar)
Then, there is a change in which the battle took place in the ford over the River Gelion but it was drowned in the River Ascar.

Now in the Tale of Years, as Findegil has posted, in version B,C and D the battle takes place in the fords over the River Ascar, but the ones who slay the dwarves are not Beren and Co. but rather Celegorm and Curufin. Now, if we are going to use the Tale of Years alternative that the fight was over the ford of the River Ascar, we should take also the fact that it was Celegorm and Curufin who were involved in the fight and not Beren and Co. Can we justify using half a sentence from there but not the other part? Doesn't that make dubious that alteration?
