Scott ducks into a nearby rain squall and continues to close on the surface in conditions of poor visibility. Through the haze, he makes out a group of oilers and cargo ships.

[2] The Japanese claim a sinking, although USS TULLIBEE is now believed to have been sunk by one of its own torpedoes that made a circular run.

[3] Operation "Transom" was one of the first major offensive air raids in which aircraft of the British Pacific Fleet participated.
