Did L win against Light? Did L win against Light? Let me elaborate:

After L's death in episode 25, we assume that Light won. But in episode 26, L leaves a message in his computer (which Light deletes in the same episode).



Also, at the end of the episode, we see that some data is being sent from L's personal computer.

So, my question is: did he know/confirm that Light was Kira and sent the case data to Near?



Note:By "winning", I mean that L defeated Light in their mind game/battle. L had confirmed that Light is Kira( but could not prove it in front of the whole world). He was able to see that Light would come to kill him in the future and confirmed that Light is Kira (when Light smiles at L's dying body). This is purely a theory based on the possibility that the transmitted data can indeed be the case data stating Light as Kira.
It really depends on what you call winning.


L had been suspicious, strongly suspicious and just a tad less strongly suspicious of Light being Kira throughout the entire anime (or, well: those potions wherein he was alive).
L, however, wanted to prove that Light was Kira with evidence that would suffice to try him guilty. Collecting enough evidence to win a court case was also the police task force’s goal. They never achieved that or they would have arrested (and subsequently tried) Light.


In games like the board game Cluedo (or Clue, if you’re on the other side of the pond), you can essentially win by guessing correctly. In crime fiction or real-world criminal investigations, you don’t win by guessing correctly, you only win by proving you’re correct. Thus, applying the rules of Cluedo, L won; but he himself wouldn’t have considered him winning due to thinking in criminal investigation terms.



Since you now clarified what you mean by winning:

L did not win the mind game. We was on a good track, but he was short of the goal. If Rem hadn’t taken action, it probably wouldn’t have been too long before L had proven to himself that Light is Kira, at which point he would have also told the world about it. However, he was stopped just short of proof.
