Why did Saber reveal to Shirou and Rin that she has participated in the previous war?


![Not the first time for Saber](https://i.stack.imgur.com/Jpqhx.jpg)

Saber did not reveal her identity to Shirou for fear of her master giving it
away to enemies and thus exposing her strengths and weaknesses. But why, even
though in front of a rival master, did she reveal the fact that she has been
summoned to the previous Holy Grail War? Wouldn't that enable Rin to deduce
whatever advantage Saber has because of her memories of the previous war and
possibly even her real identity (Servants being summoned twice and retaining
their memories was unheard of)?




Because there's nothing to gleam from the fact that she was summoned
previously, infact in the Visual Novel she doesn't say that she was summoned
in the previous War but was _"summoned once before"_ , she doesn't mention
that she was in the previous Holy Grail War until later on the 4th day where
she and Shirou talk to one another before going to be where Shirou finds out
she made it to the war's finale and questions his worth as a Master to her
(since within the first night Saber had been in 3 fights and was badly injured
in 2)

Also, Rin mentions when Saber says she was summoned previously that it was
quite rare. given what we know about the previous Wars with the exception of 3
no hero has been _properly_ summoned twice under the Fuyuki System, the
exceptions are

  * The Hassan-i-Sabbah, AKA Assassin, as all 19 leaders of the Hashshashin share the same name and the name of the sect is the etymological root of the word "assassin" with the class name itself thus acts as the catalyst to summon the members of the organization.

  * Arturia because

> She isn't a clone of a Hero from the Throne of Heroes like every other
> Servant summoned

  * and Gilgamesh because

> he was never unsummoned in the 4th war, Angra Mainyu's corruption
> unnaturally boosted his Independent Action Class Skill to the point he could
> stay in the world indefinitely

I am not including the Looped Holy Grail War which is featured in Fate/Hollow
Atarxia as

In Fate/Strange Fake Jack the Ripper is summoned as a
[Berserker](http://typemoon.wikia.com/wiki/Berserker_\(Fate/strange_fake\))
for the False Holy Grail War in Snow Field and is a male (made sane by the Mad
Enchantment Class Skill) but in Fate/Apocrypha Jack the Ripper is a young girl
summoned as [Assassin](http://typemoon.wikia.com/wiki/Assassin_of_Black) for
the Black Faction.

Also, everyone who knew her identity she presumes had died as at the time she
hadn't seen Kotomine nor know that Gilgamesh was still around and finally,
given the normal procedure in the Holy Grail Wars to kill Masters to ensure
they can't contract another Servant later on, with Gilgamesh being the only
other Servant left to confront her she would assume Iskander and Waver are
dead (however we know Waver is still alive)

As for your comment

> Servants being summoned twice and retaining their memories was unheard of

Yes it's unheard of, mainly because every Hero summoned is not the real Hero
but a clone as such they should not have memories of a previous war as the
clone who has these memories is lost at the end. the bellow image and link
explains it quite well

If this was not the case then Servants who become corrupted by the Grail
particularly those in the Heaven's Feel Route would be corrupted in the Throne
as well.
