Operation Jaywick
From Wikipedia, the free encyclopedia
Operation Jaywick was one of the most daring and celebrated special operations undertaken in World War II. In September 1943, 15 Allied commandos from Z Force raided Japanese shipping in Singapore Harbour, sinking seven ships.

[edit] Background
Special Operations Australia (SOA), a joint Allied military intelligence organisation, was established in March 1942. SOA operated under the over name Inter-Allied Services Department (or IASD). It contained several British SOE officers who had escaped from Japanese occupied Singapore, and they formed the nucleus of the IASD, which was based in Melbourne. In June 1942, a commando arm was organised as Z Special Unit (which was later commonly known as Z Force). It drew its personnel primarily from the Australian Army and Royal Australian Navy.
In 1943, a 28-year-old British officer, Captain Ivan Lyon (of the Allied Intelligence Bureau and Gordon Highlanders), and a 61-year-old Australian civilian, Bill Reynolds, devised a plan to attack Japanese shipping in Singapore Harbour. Commandos would travel to the harbour in a vessel disguised as an Asian fishing boat. They would then use collapsible canoes to attach limpet mines to Japanese ships.
Bill Reynolds was in possession of a 21.3 metre Japanese coastal fishing boat, the Kofuku Maru, which he had used to evacuate refugees out of Singapore. Lyon ordered that the boat be shipped from India to Australia. Upon its arrival, he renamed the vessel MV Krait, after the small but deadly asian snake.
[edit] The attack
Im mid-1943, the Krait travelled from a training camp at Broken Bay, New South Wales to Thursday Island. Abaord was a complement from Z Special Unit of four British and eleven Australian personnel, comprising:
- Major I Lyon (Mission commander)
- Lieutenant H E Carse (Krait's captain)
- Lieutenant D M N Davidson
- Lieutenant R C Page
- Corporal A A Crilly
- Leading Seaman K P Cain
- Leading Stoker J P McDowell
- Leading Telegraphist H S Young
- Able Seaman W G Falls
- Corporal R G Morris
- Able Seaman M Berryman
- Able Seaman F W L Marsh
- Able Seaman A W Jones
- Able Seaman A W G Huston
On August 13 1943 the Krait left Thursday Island for the US Naval Base at Exmouth Gulf in northern Western Australia where it was refuelled and repairs were undertaken.
On September 2 the Krait left Exmouth Gulf and departed for Singapore. The team's safety depended on maintaining the disguise of a local fishing boat. The men stained their skin brown with dye to appear more Asiatic and were meticulous in what sort of rubbish they threw overboard, lest a trail of European garbage lead arouse suspicion. After a relatively uneventful voyage the Krait arrived off Singapore on September 24. That night six men left the boat and paddled 50 kilometres to establish a forward base in a cave on a small island near the harbour. On the night of September 26 they paddled into the harbour and placed limpet mines on several Japanese ships before returning to their hiding spot.
In the resulting explosions, the limpet mines sank or seriously damaged four Japanese ships, comprising over 39,000 tons between them. The commandos waited until the commotion over the attack had subsided and then returned to the Krait, which they reached on October 2. The return to Australia was mostly uneventful, except for a tense incident in the Lombok Strait when the ship was closely approached by a Japanese patrol boat; however the Krait was not challenged. On October 19, the ship and crew arrived safely back at Exmouth Gulf.
The raid was later dramatised in an acclaimed Australian telemovie, The Heroes (1988).
[edit] Repercussions of the raid
The Japanese authorities in Singapore were completely surprised by the raid. Never suspecting such an attack could be mounted from Australia, they assumed it had been carried out by local saboteurs, most probably pro-Communist Chinese guerillas. In their efforts to uncover the perpetrators, a wave of arrests, torture and executions began. Local Chinese and Malays, as well as interned POWs and European civilians were targeted in this program. The incident became known as The Double Tenth, for 10th October, the day that Japanese secret police began the mass arrests.
Given the misery visited upon the local population by the Japanese, criticism has arisen as to whether Operation Jaywick was justified, especially with its relatively limited strategic results. In the aftermath of the raid, the Allies never claimed responsibility for the attack on shipping, most likely because they wanted to preserve the secret of the Krait for future similar missions. Therefore the Japanese did not divert significant military resources to defending against such attacks, instead just using their secert police to enact reprisals against civilians.
