Operation Scorpion (World War Two)

Last updated

Operation Scorpion was a proposed operation in World War II by Australia's Z Special Unit.

Contents

It was to be the first operation by Z Special Unit. Australian soldiers were to infiltrate the Japanese-controlled port at Rabaul in New Britain. The mission led to a practice raid on Townsville Harbour. The actual mission was called off but elements were used in the famous Operation Jaywick. [1]

Origins of the Plan

The plan was devised by Lieutenant Samuel Warren Carey, a Z Special Unit officer based at Z Experimental Station, Cairns, Queensland who had extensive experience of Papua New Guina. In January 1943 he approached General Thomas Blamey proposing a raid on Rabaul.

The raid would work as follows:

Blamey authorised the operation, and issued Carey a letter of authority to perform whatever actions he deemed necessary during the planning of the proposed operation. [1] Training began in March 1943 and involved selection of the team and intense training. [2]

Townsville Raid

Soldiers trained for this with a secret raid on Townsville Harbour on 19 June 1943 [3]

Carey and a team of nine men, including Bob Page, left a train at a river crossing just north of Townsville on 19 June 1943. They carried 45 sand filled limpet mines and dehydrated food for three days. They had no fuses and the mines could not be detonated.

It took them 30 hours to reach Magnetic Island. They left their base at Magnetic Island on 22 June and paddled by folboat through to Townsville Harbour. Despite the mouth of the harbour being heavily mined they managed to avoid these dangers.

Dummy limpet mines were attached to fifteen ships, including two destroyers, with three limpet mines on each. [2]

The men rowed into Ross Creek, dismantled and hid their folboats, then travelled into Townsville.

The limpets were discovered around 10:00 am the next morning. Panic ensued and it was felt that the mines were real. [4]

Carey was arrested, and only released on producing General Blamey's letter. The navy decided not to pursue legal action on the undertaking that Carey left Z Special Unit. [2] [5]

Result of Mission

Operation Scorpion was scrapped due to lack of available submarine transport and the fact that General MacArthur's island hopping strategy involved by-passing Rabaul. However lessons learned from the raid proved useful in planning Operation Jaywick and Operation Rimau. Carey's younger brother would be captured and executed in the latter. [2]

A folding kayak is a direct descendant of the original Inuit kayak made of animal skins stretched over frames made from wood and bones. A modern folder has a collapsible frame made of some combination of wood, aluminium and plastic, and a skin made of a tough fabric with a waterproof coating. Many have integral air chambers inside the hull, making them virtually unsinkable.

Operation Frankton was a commando raid on ships in the German occupied French port of Bordeaux in southwest France during the Second World War. The raid was carried out by a small unit of Royal Marines known as the Royal Marines Boom Patrol Detachment (RMBPD), part of Combined Operations inserted by HMS Tuna captained by Lieutenant-Commander Dick Raikes who, earlier, had been awarded the DSO for operations while in command of the submarine HMS Seawolf (47S). (The RMBPD would later form the Special Boat Service).

Operation Jaywick

Operation Jaywick was a special operation undertaken in World War II. In September 1943, 14 commandos and sailors from the Allied Z Special Unit raided Japanese shipping in Singapore Harbour, sinking six ships.

Z Special Unit Allied forces special unit in WWII

Z Special Unit was a joint Allied special forces unit formed during the Second World War to operate behind Japanese lines in South East Asia. Predominantly Australian, Z Special Unit was a specialist reconnaissance and sabotage unit that included British, Dutch, New Zealand, Timorese and Indonesian members, predominantly operating on Borneo and the islands of the former Dutch East Indies.

A limpet mine is a type of naval mine attached to a target by magnets. It is so named because of its superficial similarity to the shape of the limpet, a type of sea snail that clings tightly to rocks or other hard surfaces.

The name commando has been applied to a variety of Australian special forces and light infantry units that have been formed since 1941–42. The first Australian "commando" units were formed during the Second World War, where they mainly performed reconnaissance and long-range patrol roles during Australia's campaigns in New Guinea and Borneo, although other units such as M and Z Special Units performed more clandestine roles. These units were disbanded following the end of the war; however, in the 1950s it was realised that there was a need for such units again in the Australian forces. Today, the Australian Army possesses a number of units that perform more conventional direct-action type commando roles, as well as counter-terrorism response, long-range patrolling, and clandestine deep-penetration operations.

Operation Rimau

Operation Rimau was an attack on Japanese shipping in Singapore Harbour, carried out by an Allied commando unit Z Special Unit, during World War II using Australian built Hoehn military MKIII folboats. It was a follow-up to the successful Operation Jaywick which had taken place in September 1943, and was again led by Lieutenant Colonel Ivan Lyon of the Gordon Highlanders, an infantry regiment of the British Army.

Ivan Lyon

Lieutenant Colonel Ivan Lyon, was a British soldier and military intelligence agent during the Second World War. As a member of Z Special Unit Lyon took part in a number of commando operations against the Japanese and was killed during Operation Rimau while attempting to infiltrate Singapore harbour and destroy Japanese shipping there in 1944.

The "Double Tenth incident" or "Double Tenth massacre" occurred on 10 October 1943, during the Second World War Japanese occupation of Singapore. The Kenpeitai – Japanese military police – arrested and tortured fifty-seven civilians and civilian internees on suspicion of their involvement in a raid on Singapore Harbour that had been carried out by Anglo–Australian commandos from Operation Jaywick. Seven Japanese ships were sunk, but none of those arrested and tortured had participated in the raid, nor had any knowledge of it. Fifteen of them died in Singapore's Changi Prison.

A long-range penetration patrol, group, or force is a special operations unit capable of operating long distances behind enemy lines far away from direct contact with friendly forces as opposed to a Long Range Reconnaissance Patrol, a small group primarily engaged in scouting missions.
