Shortly after this sighting, Yamamoto ordered the cruisers to turn north, away from their original course for Midway. "Tambor" soon sighted them again, at 0238. The sub was now in front of the Japanese ships, which changed heading again, to the northwest. At 0258, Murphy turned due west, hoping to put them between him and the moon so their silhouettes would make them easier to identify. After losing and regaining sight of the cruisers in the dark, Murphy made an educated guess, turning left again, and re-sighted the ships.
