If you meant what were they doing during the attack, then using their inefectual AA weapons to try to impede the attack, but to no avail. After the sinkings they rescued all those that survived.
And while I am here I would just like to take this opportunity to qualify my previous statement as to M & M's "Battleship" book as being the best published account so far hands down (by a country mile), as I have owned (mostly) and or read every, and I mean every, book published on the subject since Browns' "Suez to Singapore" in 42 up to Kostums latest, inc the other books mentioned in this thread, and all other books that had a chapter or more on the subject. And in all that reading over the many years I have still found nothing to surpass M and M's. Some of the others are good, inc the two others mentioned in this threaad, but none have the scope (i.e. from both the Jap and British sides) and intensity of "Battleship".
But each to his own, that's just my opinion having read extensively on the subject.
