the HAGURO group, still unaware of the British, enters the semi-circle.
Alerted, the Japanese begin zigzagging, but remain on their southerly
course and enter the center of the semi-circle. At about 0100, the range
is down to 12,000 yards. The destroyers turn north to attack. Within

The 26th Flotilla increases speed and pursues. At 0105, the HAGURO
group reverses course to the SE and the range drops to 6,000 yards.

British destroyers claim hits with their torpedoes at ranges from 1,200
to 2,500 yards. HAGURO is hit by gunfire and at least three Mark IX
torpedoes. She slows and takes on a 30-degree list to port.
At 0232, HAGURO sinks bow first 55 miles WSW of Penang at 04-49N, 99-42E. KAMIKAZE, although damaged, escapes to Penang.

Removed from the Navy List.
 Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.
 On 1 December 2002, a group of divers including Australian
diver/photo-journalist Kevin Denlay operating off MV EMPRESS out of
Singapore, using side-scan sonar discover DeRUYTER and JAVA at a depth
of about 225 feet off Bawean Island in the Java Sea.
 On 4 March 2003, a group of divers, again including Kevin Denlay,
operating off MV EMPRESS locate the wreck of HAGURO in about 220ft/67m
of water. She sits upright, covered in trawler nets with her hull
opposite her forward turrets buried in the seabed to about her original
waterline, but this level gradually reduces until at the stern her outer
propellers and shafts are actually up above the seabed! Her foremast
and the top half of the bridge structure are missing/collapsed. Her
mainmast is collapsed. Her funnels are missing. British hits are visible
in places. The bow section forward of No. 2 turret is decimated.
HAGURO's No. 1 turret and barbette are completely uprooted and now lay
across the wreck, the rear of the turret on the starboard sea bed and
the barrels pointing vertically towards the surface. Her No. 2 turret is
trained to starboard at approximately the 1 o’clock position, with its
roof collapsed and both barrels and breach’s missing (i.e. not replaced
after damaged by a bomb at Leyte Gulf). Her No. 3 turret's guns are
askew and trained to the port quarter, i.e. the 8 o’clock position. Both
her stern main turrets’ guns point almost directly astern. Just behind
the No. 5 turret, the wreck is broken completely in half, although the
very stern section is still ‘partially’ attached and heavily damaged on
the port side.
 On 21 February 2007, a group of divers operating from MV EMPRESS out
of Singapore, including Australian photo-journalist Kevin Denlay,
locate the wrecks of British heavy cruiser HMS EXETER and destroyer HMS
ENCOUNTER in the Java Sea, 350 nautical miles from Sunda Strait. EXETER
lays on her starboard side in 60m/200ft of water. Her faithful consort
ENCOUNTER rests about two miles away.
 In December 2008, the remains of USS POPE (DD-225) was located in
the Java Sea in approx 105 feet/32 meters of water by owner/skipper
Vidar Skoglie’s dive vessel MV EMPRESS operating out of Singapore. The
old destroyer appears to have been found earlier by Indonesian salvage
divers and very little remains but a rusted iron ‘skeleton’.
 In December 2010, Kevin Denlay and a group of divers returned to
the wreck of HAGURO. Diver Andrew Fock reports that they had the great
visibility and conditions on the site and that contrary to Note 
above, No. 2 ("B") turret is not pointing to starboard, but is facing
towards the bow.
