(FROM THE ARCHIVES OF THE USS ARIZONA & PEARL HARBOR REMEMBERED MESSAGE BOARD 2/11/01)
In answer to your questions, I'll breifly explain here. You can certainly e-mail me if you would like to discuss this further.
The National Geographic search for Midget A in November 2000 did turn up two torpedoes. They were not torpedoes from any of the submarines used in the attack on Pearl Harbor in December 1941. These two torpedoes were recovered by the U.S. Navy later in the war and dumped there. You can tell they were dumped because (1) they were found in the known dump site used by the Navy for that purpose and (2) The warheads were removed mechanically leaving the mounting flange clearly visible. They had not exploded nor had the warheads been knocked off in an attack on one of the midget submarines. Had that been the case the mounting flange without the attaching screws would not be so clearly visible and the break would not be so clean.
The same applies to the portion of the midget submarine they found (previously located by the way). That midget submarine was captured / recovered by the U.S. Navy later in the war and taken back to Pearl Harbor for inspection. It was then dumped. Note that the aft hull section was mechanically disassembled, not violently torn apart from the rest of the boat, and there is still a lifting sling lying on the hull from when they dumped it.
The 1960 midget submarine you refer to is known as Midget D, for lack of a better designation. It came from either the I-18, I-20 or I-22, although there is no way to know from which despite frequent and unfounded speculation. She was found in shallow water with both torpedoes intact. The conning tower hatch had been opened from the inside and no crew remains were found onboard. This led to much speculation in the media concerning the fate of the crew.
At least one hoax article (December 1967 "Our Navy" magazine) was written about this boat and it was recently cited as possible "proof" of the submarine's identity by the same people who brought us the fantasy about another midget submarine being in Pearl Harbor on December 7 1941. Their abysmal record for accuracy that began with their December 1999 Naval History magazine article was continued in their December 2000 Proceedings magazine article.
You cannot take anything they say at face value without seriously questioning all of it.
As far as the Breese sighting of two submarine conning towers on the morning of December 7 1941- Yes, one man on Breese did report seeing a second conning tower. However no one else on Breese saw it nor did anyone on any of the other eight ships who sighted the one actual submarine.
As a matter of fact, the Executive Officer on Breese reported seeing only one submarine in his report. This was Midget B (also known as the Monaghan midget). The second conning tower sighting was a combination of excitement, nerves, floating debris, or the same black cage buoy that Monaghan fired on moments later.
Hope this helps!
