 Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.
 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. The two warships were found at a depth of about 60m/200ft, 90 miles north of Bawean Island, about 350 nautical miles from Sunda Strait. EXETER lays on her starboard. Her faithful consort ENCOUNTER rests about two miles away. About 50 of EXETER's crew were killed, while 650 were made prisoners of war. Of these, 152 died in Japanese PoW camps. About eight of ENCOUNTER's crew were killed and 149 were made PoWs, of whom 38 died in captivity.
 On 3 March 1942, destroyer INAZUMA returned to the scene and rescued 151 of POPE's crew from life rafts and a lone whaleboat. Only one of POPE's crewmen was lost in the battle. INAZUMA landed the POWs at Makassar, Celebes. Earlier, on 1 March, INAZUMA had rescued 376 of EXETER and ENCOUNTER's crewmen.
 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’. The wreck has been heavily damaged by the salvors using explosive charges.
