Space Battleship Yamato 2199 - 1x11 - いつか見た世界- Followmy.tv

Melda Ditz, a Gamilan pilot under the custody of Yamato, claims that their attack on Earth was not unprovoked, and that it was the Earthlings who first fired without warning during the first contact between both races years before. Daisuke, whose father was killed in the attack, does not believe her at all until Yamazaki, the sole survivor of his father's ship, reveals to him the truth about what really happened that day.
