Interesting blurb in the Nimitz Graybook about the Antares sighting a midget sub. That was not the first encounter between Antares and a Japanese midget sub; as Antares entered the channel into Pearl Harbor on the morning of December 7, 1941, she was trailed by a midget submarine that was sighted and attacked by USS Ward. The first shots fired by the United States in World War 2.
As I recall there was some skepticism that the Ward really had scuffled with a sub due to no sub and no debris. That was until a team located the sunken sub on the seabed outside Pearl.
