KIRK: It's not a rescue mission, listen, it's an attack.
SPOCK: Based on what facts?
KIRK: That same anomaly, a lightning storm in space that we saw today, also occurred on the day of my birth. Before a Romulan ship attacked the USS Kelvin. (to Pike) You know that, sir; I read your dissertation. That ship which had formidable and advanced weaponry was never seen or heard from again. The Kelvin attack to place on the edge of Klingon space and at twenty-three hundred hours last night, there was an attack. Forty-seven Klingon warbirds destroyed by a Romulan, sir. It was reported that the Romulans were in one ship, one massive ship.
PIKE: And you know of this Klingon attack how?
