World War I
The South African Irish was formed at the outbreak of World War I in August 1914 when three officers (Major George Twomey, Captain J. Jeoffreys and a Captain MacDonald) met at the Irish Club in Johannesburg to raise an Irish regiment from among the citizens of Johannesburg and its surrounding areas.
After a request to The Union Defence Force (UDF) Headquarters, authority was granted to form the regiment and Lieutenant-Colonel Brennan was appointed as its first commanding officer. Major Twomey was appointed as its recruiting officer. The wife of General Louis Botha (a lady of Irish descent with the maiden name of Emmett) was appointed as the regiment's first honorary colonel.
Sources are not clear on the official date of formation of the South African Irish, but it is either 9 September or 1 December 1914. In any case, the battalion, consisting of six companies, first formed up at Booysens Camp in Johannesburg on the former date.
After training, the regiment was made part of 4 South African Infantry Brigade (part of the Northern Force) and embarked from Cape Town to the (then) German South-West Africa on 21 December 1914. On 25 December 1914, the Force landed at Walvis Bay and went into action immediately. The Regiment itself first came into contact with their German enemy on the following day, barely three months after it was raised.
At the end of the campaign in South-West Africa, Active Citizen Force regiments were by law not permitted to proceed to other theatres of war as such. Special war service units were thus created to fight in East Africa and Europe. Volunteers from the South African Irish Regiment were formed, together with members of other units, into the composite 9 South African Infantry Regiment. 9 SAI campaigned in East Africa, where it earned the honours Kilimanjaro and East Africa 1916–17.
The SA Irish were formally disbanded on 31 December 1919.
On 29 January 1921, at a ceremony in Johannesburg, the regiment was posthumously presented with the King's Colour by Prince Arthur of Connaught, the (then) Governor-General of the Union of South Africa, in recognition of its service in South-West Africa.
World War II
Mobilisation
At the outbreak of World War II in 1939 the 1st South African Irish Regiment was reformed through the efforts of Major Twomey, Captains Jeoffreys and Cullinan (the latter was the son of Sir Thomas Cullinan, of diamond fame).
Although the unit was designated as the 1st South African Irish a second battalion was never formed as the men intended for this second battalion were drafted to the first. In practice, the usual designation for the regiment was thus the South African Irish Regiment.
The South African Irish Regiment initially consisted of a regimental HQ, a Support Company and three infantry companies; a pipe band was later added.
After a period of training, the regiment was mobilised on 16 June 1940 under the command of Lieutenant-Colonel D.I. Somerset. It was grouped together with 2 Regiment Botha and 3 Transvaal Scottish to form the 5th South African Infantry Brigade. In July of the same year, the brigade was shipped to Kenya via the port of Durban to become part of 1st South African Infantry Division.
East Africa
After concentrating at the town of Gilgil in Kenya, the regiment took part in the invasion of Southern Abyssinia on 1 February 1941, part of the East African campaign; it distinguished itself during the fighting at El Gumu, Hobok and Banno in early February as well as during the capture of Mega on 18 February.
5 Brigade, including the South African Irish, then returned to Kenya and embarked at Mombasa on 18 April. The Brigade reached Suez in Egypt on 1 May.
Western Desert
In November 1941 Operation Crusader, the invasion of Libya and relief of Tobruk, began. 5 South African Infantry Brigade, together with the Transvaal Horse Artillery Regiment, took part in the fighting at Sidi Rezegh culminating on 23 November 1941 with the German armour overwhelming the Allied forces, destroying 5 Brigade, and breaking through to the Eighth Army's rear areas on the Libyan border with Egypt. The casualties of the South African Irish were extremely heavy (only 140 men of all ranks survived), including its commanding officer, Lieutenant-Colonel Dobbs who was wounded in the early stages of the battle (he was replaced by Major C. McN. Cochran). [1] : 263 Major Cochran then led the remnants of the battalion, along with the remaining five guns of 9th Field Battery eastwards towards the lines of the Scottish (these were the only guns in 5 Brigade which were not captured!), in an attempt to escape. [1]
In addition, several members of the unit drowned while on their way to Italy by ship as prisoners of war. The survivors of the regiment served with New Zealand forces until the end of November when they rejoined the remnants of the decimated Brigade at Mersa Matruh.
Due to their heavy losses, the South African Irish and 3 Transvaal Scottish ceased to exist as independent infantry units. In February 1942, the survivors of these two battalions joined together to form a composite battalion and it was later reconstituted as 2nd Regiment Botha under command of Lt-Col Boerstra. 2nd Regiment Botha was then further reinforced with replacements coming from the 2nd Witwatersrand Rifles after which, the battalion moved by rail and in New Zealand troop carriers from Mersa Matruh to El Adem. [2] : 179 In this form, the remnants of the South African Irish were once again in action during September 1942, during the fighting at El Alamein.
11 Battery, 4 Field Regiment, South African Artillery, returned to the Union of South Africa in 1943 and was reconstituted as 4/22 Field Regiment, South African Artillery. This unit later returned to North Africa as a component of the South African 6th Armoured Division and also took part in the subsequent fighting in Italy.
The regiment received four battle honours (see below) for its service during World War II, but they were not awarded immediately because, at the time of the publication of the honours, the unit was an artillery regiment – artillery regiments in the South African Army do not carry any honours. However, when the regiment was later converted back to an infantry unit it became entitled to those honours and they were incorporated into the colour of the regiment.
Post-War
At the end of World War II, it was requested that the regiment be reformed as an infantry unit. However, as there was no intention at that time to establish additional Active Citizen Force infantry battalions, this request was refused. However, as a form of compensation, authority was granted for the formation of an artillery unit with the designation of 22 Field Regiment (South African Irish), South African Artillery. This unit was formed in June 1946 and it operated until 31 December 1959 as an artillery regiment. However, on 1 January 1960, the regiment was converted back to an infantry unit and regained its old nomenclature, the South African Irish Regiment.
The period from 1960 to 1974 saw the regiment entrenching its traditions as an infantry regiment and during this period received the Freedom of the City of Johannesburg (Nov 1966), and their Regimental Colours (Nov 68). During this period the regiment formed and trained the Hunter Group, a volunteer special force unit, which was the precursor to the Reconnaissance Regiments.
In 1971 members of the regiment and Regimental Association started the annual visit or "raid" to Barberton. In 1966 and 1971 the regiment participated in the 5th and 10th respective anniversaries of the Republic.
Citizen Force Divisions and the Border War
The period from 1974 to 1988 saw the regiment being part of 7th South African Infantry Division's 72nd Motorised Brigade and being re-established as a conventional force. During these years the regiment saw active duty in Angola during Operation Savannah and Operation Protea as well as undertaking operational duties during the Border war, together with internal security duties within South Africa; and exercises at the Army Battle School, e.g. Quicksilver and Thunderchariot. In 1987, the regiment underwent conversion from a motorised infantry regiment to a mechanised infantry regiment.
In 1979 the regiment was granted the Freedom of entry to the City of Barberton because of the WWII training period and the frequent "raids" to the town. In 1984 the regiment, as part of 72 Motorised Brigade, participated in the parade celebrating the 10th Anniversary of the brigade's Formation.
In 1989, due to the reorganisation of the forces within the conventional force brigades, the regiment was transferred to 8th South African Armoured Division's 81st Armoured Brigade. This year was also the 75th anniversary of the formation of the regiment and this event was celebrated by a battalion parade in Barberton.
In 1991 the regiment organised the National 50th anniversary of the battle of Sidi Rezegh Parade in Johannesburg. In the same year, due to further restructuring of the conventional forces the regiment was transferred to Northern Cape Command and reverted to a motorised infantry regiment. During this period the regiment successfully completed township unrest camps as well as training exercises at the Army Battle School.
Post 1994
From 1992 to 1998 the regiment went through a period of significant decline as the annual intake of national servicemen dried up with the ending of conscription. In 1998, the regimental muster was only four strong.
In 1999, the regiment began to recruit untrained members directly from the streets, training them on a part-time basis. At the completion of internal training, the recruits were then sent to a regular army training establishment for final assessment and evaluation. The success of this approach lead not only to the expansion of the concept, but also the transformation of the regiment, with not only the first black riflemen entering the ranks but black Officers and NCOs joining the unit.
By 2004, the regiment had grown back to two companies in strength and a Regimental HQ, the same size it had traditionally been during the 1950s and 1960s.
Deployments
By 2005, members of the regiment were being deployed in the Democratic Republic of Congo (DRC) in support of UN peace support operations. At the same time the regiment reached an active strength of 532 members.
2006 saw members of the regiment again deploying externally to the DRC, whilst domestically the regiment was tasked with executing conversion training for ex Commando members converting to the conventional reserve following the closure of the ATR.
In 2007 SAIR was again tasked with ATR/ACR conversion, while 2008 saw SAIR providing 50 members to the Witwatersrand Rifles company deploying to the Sudan. At the same time, the regiment received orders to prepare for further deployment to the DRC in 2009.
Name change
In August 2019, 52 Reserve Force units had their names changed to reflect the diverse military history of South Africa. [3] The South African Irish Regiment became the Andrew Mlangeni Regiment, and have 3 years to design and implement new regimental insignia. [4]
