I didn't say otherwise. I said this: "
Whatever battles he may or may not have fought in during the First Age aside,
Celebrimbor does not appear in
Tolkien's
Quenta Silmarillion.
Celebrimbor appears relatively briefly in the twelve volumes series
as the son of Curufin, because,
as I said, Tolkien didn't imagine him as being Curufin's son until later-ish -- and he published the "descendant of
Feanor" detail in the
Second Edition [1960s] of
The Lord of the Rings.
And after that [later 1960s, or even later] again as I noted, Tolkien re-imagined Celebrimbor as a
Sindarin Elf rather, or a Telerin Elf as well, because he'd apparently forgotten what he'd published.
This is not stated in [the twelve volume]
The History of Middle-Earth series.
What Tolkien stated, as I already posted above, was that Celebrimbor
was a refugee in
Nargothrond, and thus, I guess it's certain people who make web sites who are taking that much to mean that he
"fought" with his father at this war . . .
. . . did he fight?
I'm not arguing either way, all I'm reporting is what Tolkien actually wrote, and that Celebrimbor does not appear in Tolkien's
Quenta Silmarillion.
He was edited in there by Christopher Tolkien, based on his father's note. Christopher Tolkien's edit reads:
"In that time Celebrimbor the son of Curufin repudiated the deeds of his father, and remained in Nargothrond; yet Huan followed still the horse of Celegorm his master."

I'm just agreeing with
Tar-Elenion, and reporting what Tolkien actually wrote versus what you seem to have read on line.
