Excellent. Something of the sort for Cirdan's participation in the War of Wrath, or even just answering the summons of Fionwë, would clinch the OP question.

You are assuming. And you are imagining a lot. Fanfic territory, not "The Works of J.R.R. Tolkien".We all know there's no 100% canon answer to that. We are just assuming based on his characterization.
Your assumption, interpretation, of track record. With a lot of your posts, I have to wonder if we've been reading the same books. But then I know this can happen. What JRRT called the reader's applicability; there are as many applicabilities as there are readers. To each his / her own; some of yours are definitely not mine....based on track record and characterization of Cirdan. I don't like to assume Cirdan broke character.
Hello olorgando, It is also written on the tolkien gateway that cirdan fought in the war of the last alliance.Excellent. Something of the sort for Cirdan's participation in the War of Wrath, or even just answering the summons of Fionwë, would clinch the OP question.
Long story, short: It's possible and even likely given his track record but there's nothing official saying he did. Everyone is on their own on this one.Your assumption, interpretation, of track record. With a lot of your posts, I have to wonder if we've been reading the same books. But then I know this can happen. What JRRT called the reader's applicability; there are as many applicabilities as there are readers. To each his / her own; some of yours are definitely not mine.
I disagree with you on this. Just because an elf isn't among the commanders doesn't mean he wasn't in that battle. So that's not all.😉Roll call of all named characters in the War of Wrath (source: Later Annals of Beleriand, Quenta Silmarillion):
Eonwe/Fionwe: Herald/son of Manwe
Ingwiel: son of Ingwe
Morgoth: the dark enemy
Ancalagon the Black: dragon
Thorondor: eagle
Earendil: the Mariner
That is all!

The War of the Last Alliance is not the War of Wrath. In LotR, Elrond tells Frodo at the “Council of Elrond” that he and Círdan were with Gil-galad at the penultimate battle on the slopes of Orodruin between Sauron, Gil-galad, and Elendil, while Isildur was with Elendil.
Citation, please. Círdan either “awoke” (which would make him one of the first Nelyar (“thirds”, the third tribe or clan, the forerunners of those who became the Teleri and Sindar, the most numerous of the three tribes (or clans) of Elves)) or was born (from Elven parents) at Cuiviénen. Nowhere does Tolkien write or imply that, “Cirdan is the first elf to awaken in Middle-earth.” That would make him the leader of the Nelyar, and though he is regarded by the Sindar as one of their lords, one of the chief of the Sindarin lords remaining in Middle-earth (Celeborn and Thranduil would be others), and there is reasonably good evidence that he is the oldest Elf (of the Elven nobility at any rate) remaining in Middle-earth, there is no evidence of which I am aware that he was the first Elf to awaken.Also, Cirdan is the first elf to awaken in Middle-earth.
[Círdan’s] name is mentioned in all wars in Middle-earth history except the War of the Ring and Dagor Bragollach. Why shouldn't such a character heed Eönwe's call for war?
Decent arguments, but contrary to the written material we have. Silmarillion says (“Of the Voyage of Eärendil and the War of Wrath”),Cirdan did answer to summons of GilGalad to go thousands of miles away from home. Why wouldn't he answer to summons of the chief demigod.
He always answered to summons. ...
I agree with you that absence of evidence is not evidence of absence, but I disagree with your conclusion that it justifies asserting that Círdan participated in the War of Wrath. He did not. Once again, Silmarillion plainly tells us, “None of those Elves who had dwelt and suffered in” Middle-earth went with the Host of the Valar to the War of Wrath. None of them. That includes Círdan. To the contrary: We have every indication he sat that one out.I disagree with you on this. Just because an elf isn't among the commanders doesn't mean he wasn't in that battle. So that's not all.
Alcuin, Alcuin, that is so old school. Haven't you heard / read of that tenet of, I can only guess, "new" logic?:I agree with you that absence of evidence is not evidence of absence,
Just looks like a bad hair day to me (very bad, to be truthful ...) 😁
