In 1939, 1 RHA was part of 51st (Highland) Infantry Division, and fought at Saint Valery. The Regiment was captured after severe fighting, but some batteries managed to escape after the Battle of Dunkirk. The Regiment reformed and was deployed to Northern Africa in late 1940. The Regiment then arrived with the Middle East Command in October 1940 and took a large part in Wavell's Campaign which opened on 9 December 1940. The most notable actions were those during the Siege of Tobruk and all the batteries fought during the fierce fighting just before El Alamein and then the First and Second Battles of El Alamein itself.[3]

1 RHA then joined 10 Armd Division in Aleppo and spent the next year training all over Syria, Palestine and the Suez Canal Zone. 1 RHA then landed in Italy from Palestine in May 1944 at Taranto, and were in action south of Rome on 15 May 1944 and thereafter played a full part in the remainder of the Italian Campaign and finished the war in Italy.[3]

The regiment saw service as follows:[4] 1 RHA was stationed in Palestine after the Second World War, during the period of terrorist activity that led to the creation of the State of Israel.[4] 1 RHA returned to England as part of 6th Armoured Division at Salisbury Plain in 1951.[4] in 1952 1 RHA moved to Münster in West Germany, where they remained until 1958 as part of the 20th Armoured Brigade of 6th Armoured Division.[4] In 1958, it moved to Hildesheim, where it was equipped with the M44 Self Propelled 155 mm Howitzer.[4]

In 1965, RHA deployed to Aden with three batteries (each split into three independent two-gun sections), where they supported British battalions in the Radfan, and South Arabian battalions on the Yemeni border. On returning from the region, the regiment was based at Kirkee Barracks, Colchester Garrison and subsequently renamed as 1st Field Regiment Royal Horse Artillery, and its batteries also taking the new designation. The regiment was then equipped with the 105mm Pack Howitzer, and assigned to the 19th Infantry Brigade.[4]

Elements of 1 RHA were deployed on Operation Banner in November 1969. As part of support to support 3rd Infantry Brigade, units were deployed to Long Kesh and Belfast City Centre. After returning from Northern Ireland, the regiment was granted the Freedom of the City of Nottingham. In May 1970 they moved to Hobart Barracks in Detmold and equipped with the new Green Archer Radar and joined CRA, 4th Armoured Division in support of the 20th Armoured Brigade.[4][5]

The regiment then deployed to Northern Ireland on Operation Banner three more times, Sep 72 - Jan 73 in Long Kesh, Mar - Jul 74 in Belfast (City Central), and Mar - Jun 76 Belfast (Grand Central/City Centre). In September 1976, the regiment was equipped with the new Cyberline Radar, and the batteries re-equipped with the FV433 Abbot SPG, and E Bty subsequently became an independent abbot bty. In March 1977 the regiment moved to Alanbrooke Barracks, Topcliffe and E bty remained for one year until joining the regiment again in March 1978. In 1979 the regiment was re-equipped with the new FH70 155mm Field Howizer and joined the 24th Airportable Brigade.[4][5]

In April 1982 the regiment moved to back to Germany, and was based at Haig Barracks, Hohne Garrison, re-equipped with the Abbot 105mm and joined CRA, 1st Armoured Division, and from 1988 in the close support role for the 22nd Armoured Brigade. Just after moving back to Germany, the regiment gained D Battery from 45th Regiment Royal Artillery, but in April 1984 the bty moved to 3rd Regiment Royal Horse Artillery.[4]

When the Cold War ended in 1990, the Options for Change reforms were published, and the regiment ordered back to England within the next two years. Another change was during the Gulf War, all three batteries, A, B, and E amalgamated to form A/B/E Bty for Gulf service. On returning from the gulf in April 1991, the batteries were separated into their independent identities again. In September 1992, the regiment moved to Assaye Barracks, Tidworth, renamed as 1st Regiment Royal Horse Artillery and re-equipped with the L118 light gun in CRA, 3rd (United Kingdom) Mechanised Division in support of the 1st Mechanised Brigade.[4]

In September 1993 the regiment was equipped with the new AS-90 and the observation parties equipped in the Warrior tracked armoured vehicle. In December of that year, L (Néry) Battery and O Battery (The Rocket Troop) joined the regiment after the disbandment of the 2nd Regiment Royal Artillery, and O Bty became O Headquarters Battery (The Rocket Troop) of the regiment. The regiment now controlled the following batteries after the recent reforms; A Battery (The Chestnut Troop), B Battery, E Battery, and L (Néry) Battery as field batteries, and O Headquarters Battery (The Rocket Troop). In April 1994 the regiment's radar troop deployed to Bosnia and the regiment then joined and deployed many times until 2002 when it ended its last deployment.[4]
