Did the moon sink the Indianapolis? By a different mechanism?

No, I believe it was the rising sun that sank the Indy.
If I recall correctly, the clouds cleared at just the right time for the moon to illuminate the Indianapolis as the Japanese sub had lined up the perfect firing solution.
As with all man-made disasters, it wasn’t just one thing but a chain of events which determined the outcome.
Any one of the events going differently would have changed the outcome.
