Second World War Early Commando units were all from the
British Army, but by February 1942, the Royal Marines were asked to organise Commando units of their own, and 6,000 men volunteered. No. 42 (Royal Marine) Commando was raised in August 1943, under the command of
Lieutenant Colonel Reginald Carteret de Mussenden Leathes from the 1st Royal Marine Battalion, as part of the expansion of the
commandos. They were assigned to the
3rd Special Service Brigade and served in
India and
Burma in 1943–45, including operations in the
Arakan and
Assam. It took part in the third Arakan campaign and carried out a series of amphibious landings down the Burmese coastline. Including the landings at
Myebon and the
Battle of Hill 170. It then returned to India to prepare for
Operation Zipper the invasion of
British Malaya. The war ended before the operation began and the commando was diverted to reoccupy
Hong Kong.
Post-Second World War Following the Second World War
1st,
2nd and
4th commando brigades disbanded leaving only one brigade – the 3rd (40(RM), 42(RM) and 45(RM)). The Commando was involved in operations during the confrontation with
Indonesia (Borneo). It was during this tour that the famous
Limbang raid was conducted by Lima Company. Throughout the following decade it was based in
Singapore at (RNAS Sembawang).
Return to UK After the return to the UK, the Commando was deployed to
Northern Ireland, the
New Hebrides in 1980 and exercised regularly overseas. More recently the Commando has seen operational service in
South Georgia,
Montserrat in 1995,
Iraq and
Afghanistan.

Argentine invasion of the
Falkland Islands, the Commando deployed on
Operation Corporate. On 21 May the Commando were

San Carlos under
Lt. Col. Nick Vaux RM. The unit was deployed to seize
Mount Kent in a night move by helicopter. By 4 June the unit had moved forward, mostly under cover of darkness, to positions west of high ground overlooking
Port Stanley and the last Argentine stronghold. After days of probing
reconnaissance, a Brigade assault took place on the night of 11/12 June in which the Commando's task was to
secure Mount Harriet on the Brigade right flank. By moonlight and in freezing temperatures, 42 Commando moved undetected through enemy minefields in a right-flanking movement to surprise the enemy in their rear. Consecutive assaults by "K" and "L"
Companies followed, up steep slopes onto company positions. Against strong resistance and continuous
artillery bombardment, the Marines prevailed. By first light more than 30 enemy had been killed and over 300 prisoners taken as 42 Commando consolidated on Mount Harriet. 42 Commando suffered two fatalities themselves – one on Mount Harriet and one on Wall Mountain. For the bravery shown in the attack on Mount Harriet, 42 Commando was awarded one
DSO, one
Military Cross, four
Military Medals and eight men were
