- Dutch submarine O-20
The "O-20" was a Dutch
O-19 classsubmarine in the Royal Netherlands Navythat saw service during World War II. "O-20" along with her sister ship "O-19" were the first boats in the world to be equipped with a "getrimd diesel systeem" or "snort system" that allowed the submarine to run its diesel engines while submerged.
"O-20" was laid down
June 151936 as the "K XX". After which at some point she was renamed "O-20". She was launched on January 311939, and on August 28of the same year she was commissioned and assigned to the command of Ltz. I A.J. Bussemaker.
She was put into a squadron that consisted of two submarines: "O-20" and "O-15", and the
sloop"van Kinsbergen". This squadron departed the Netherlands for the Netherlands West Indies on either October 2or 3rd 1939.
December 23 1939"O-20" reached the Netherlands West Indies via the Panama Canal.
World War II
May 10 1940Germany attacked the Netherlands
May 31 1941the "O-20" was put in the command of F.J.A. Knoopsfollowed by Ltz. I P.G.J. Snippein September 20 1941.
December 7 1941, the Japanese attack Pearl Harbor, brought the US into the war. The Netherlands follow suit hours later.
*By early December 1941, O-20 has been stationed at Singapore Submarine Base and is under the command of the
British Eastern Fleet.
The Sinking of "O-20"
December 14 1941"O-20" was under orders to patrol the South China Sea. On the 14th, two battleships and six cruisers were sighted, "O-20" and "O-19" were given orders to gain position on the enemy ships. The two subs would split paths en route to the target when 13 transports were spotted off Patani, Thailand and another 20 off Kota Bharu, Malaysia.
Given a new patrol route, "O-20" spotted Japanese destroyers off and on from
December 17to 19th. On the 19th at 7:00, she spied two Japanese transports being escorted by two destroyers. In a few hours a third destroyer joined them. These destroyers were the "Ayanami", the "Uranami", and the "Yugiri".
At 11:00, "O-20" was spotted by enemy planes which dropped two bombs on the submarine and alerted the destroyers to her presence. The submarine dove and was able to avoid the bombs, but the destroyers began to drop
depth charges which soon destroyed the sub's listening device and caused other minor damage.
The destroyers scanned the bay for "O-20", dropping eight depth charges every half hour. Some of these detonated directly above the submarine, but were set to detonate too shallow to badly damage it. (It turned out that the next deepest setting would have buried the charges in the mud)
In order to escape, the commander ordered full speed ahead with all planes set to rise, but "O-20" had become mired in the mud. An air tank was blown in an attempt to loose the submarine from the seabed, but also ended up alerting the destroyers to "O-20's" position by releasing bubbles.
That night, the commander attempted to surface to escape at full speed, but was detected by a new Japanese
sonar. Two more tanks were blown and the sub surfaced at a 25° angle and engines were set to full speed. Because of some pre-existing defects "O-20" began to take on water at the screw shafts.
The hatch was opened and with no enemy ships in sight, the machine guns were not manned or prepared. The commander decided to dump a fuel tank in order to escape even faster, which rose the sub even higher in the water exposing the diesel exhaust pipes. Due to more pre-existing damage coupled with damage from the depth charges, the pipes began to spark, giving away the "O-20's" position to anyone who looked in her direction. The commander decided to do nothing.
After 20 minutes of running in this manner, one of the destroyers (the "Uranami") closed in, spotted the "O-20" with her searchlight and opened fire. The shot missed. The commander now ordered the machine guns manned, and the ship turned about to fire the torpedoes. She couldn't get in position until after the fourth volley, which struck the Conn Tower and main hull. "O-20" returned fire with the 40 mm machine gun. The port side torpedo was ordered to be fired, but because of extreme vibrations due to the speed, both sides fired. Both torpedoes missed.
The sub badly damaged, the commander decided then that there was no hope for escape, and ordered all hands on deck. He then ordered the sub be scuttled by flooding all the main ballast tanks. The sub descended under the water, still running at full speed, as the crew floated above. "Uranami", apparently not noticing that the crew had abandoned ship, followed the sub, cutting through the stranded shipmates at convert|20|kn|km/h|0, and dropped depth charges on the now abandoned sub.
After daylight, "Uranami" rescued the 32 survivors, she had dropped depth charges throughout the remainder of the night to keep sharks away. Seven men, including the commander were found to be missing. The commander was known to not have been wearing his life vest, it is possible that this is how the other six perished as well. An alternative suggestion is that since the six men all worked in the engine room, they may have not been warned in time to evacuate the ship before it was scuttled.
June 12 2002a group of 7 Dutch divers associated with the [http://www.iahd.org/en/index.htm International Association for Handicapped Divers] participated in a dive expedition to locate the "O-20". The dive, led by IAHD CEO Klaas Brouwer, Dive Leader Michael Lim, and Mr H Besançon, also included three physically handicapped members.
The wreck is located approximately convert|35|nmi|km|0 NE of Kota Baru, Malaysia at a depth of about 144 ft (44 m). The divers report that the masts are no longer visible, the snort is gone, and that the bridge was shelled so badly it could be seen through easily. The divers retrieved a deck phone from the sub in order to positively identify it, but left the wreck alone, as it was likely the gravesite of six seamen.
