Eight Honorary Stars
When the Grayback carried out its final mission, the submarine was responsible for sinking a Japanese commercial vessel that weighed a remarkable 21,594 tons. During this journey, Moore was in command for the third time, and he was posthumously awarded a third Navy Cross in recognition of his actions at sea during the voyage. Following her service in World War II, the Grayback was given eight battle stars for her efforts on the battlefield.
One Vital Mistake
Despite the fact that the Grayback and her strong crew of 80 men had been missing for decades, it would be more than half a century before anybody could find out exactly what had happened. Initially, according to the United States Navy, she was believed to have sunk beneath the waves roughly 100 miles southeast of Okinawa, Japan, when she went missing. The difficulty is that this assumption was based on data that was later shown to have a vital mistake.
