I-19 conducted the most ‘successful’ torpedo attack in the history of naval warfare on that terrible day.

I don't know about that. I-19 needed 3 torpedoes to sink Wasp.

On 19 June 1944, IJN Taihō was sunk by USS Albacore (SS-218) with a single torpedo.

On September 15, 1942, while patrolling south of the Solomon Islands during the Guadalcanal Campaign under the command of Commander Narahara Shogo,[2] I-19 sighted and attacked the U.S. carrier Wasp, firing six torpedoes. Three of the torpedoes hit the Wasp, causing heavy damage. With power knocked out due to damage from the torpedo explosions, Wasp’s damage-control teams were unable to contain the ensuing fires. She was abandoned and scuttled.

The remaining three torpedoes from the same spread (torpedo salvo), often incorrectly attributed to a second Japanese submarine, hit the U.S. battleship North Carolina and the destroyer O'Brien, the latter of which later sank en route for repairs on October 19, 1942. Significant damage had been sustained by North Carolina, which underwent repairs at Pearl Harbor until November 16, 1942.

This single torpedo salvo thus sank an aircraft carrier and a destroyer, and severely damaged a battleship, making it one of the most damaging torpedo salvos in history.[3]

The single torpedo hit normally would not have sunk Taiho. In fact, she was still floating and conducting normal air operations six hours later. What finally killed her was inept damage control procedures when the poorly trained chief damage control officer vented fumes not overboard but into previously uncontaminated spaces where sources of ignition were.
