This evidence points to a Uesugi victory, though it is impossible to say whether the clearly biased Takeda document (which IIRC states that they lost equal numbers of soldiers) is correct that they won tactically or if Kenshin won and the Takeda were just covering up a shameful battle that few living people had actually been in.
