So the officers were relieved of their duties for what reason?
Yeah, the mountain pulled right out in front of the San Fransisco and didn't even have it's clearance lights on.
From the article:
The Navy has placed the blame on the captain and the crew, and Commander Mooney says, "I accept full responsibility." He acknowledges several critical mistakes, including going too fast, taking insufficient depth soundings and failing to cross-check the route with other charts.

Looking at a picture of that moment, Commander Mooney speaks with pride of the way his crew brought the boat home. But an image discovered on the voyage back also remains seared in his mind, he says, one that helped seal his dismissal and spark broader questions about the Navy's navigational training and support.
That image is a small, light-blue circle on a white background. It signifies a potential hazard two to three miles from where the San Francisco crashed - close enough, Commander Mooney says, that if he had known about it, he would have tried to skirt the area or asked for a new routing. Charting experts now believe that hazard was the mountain, and that its location was imprecisely reported in the days before satellites made navigational fixes more precise.
Commander Mooney said he first heard about the hazard from his boss onshore a few hours after the grounding. It is, in fact, on every chart of the area except for the one that the boat was using - the one that usually provided the most detailed picture of the seabed contours.
