The Orkney Heavy Regiment was a Territorial Army unit of Britain's Royal Artillery raised in the Orkney Islands just before World War II. During the war it was greatly expanded to defend the vital naval base of Scapa Flow. It was reformed postwar and later became an air defence battery.
There had been previous volunteer artillery units in the Orkney Islands: the Kirkwall Gunners during the Napoleonic Wars, and the 1st Orkney Artillery Volunteers (OAV) formed in 1860. By 1914 the OAV had become the Orkney Royal Garrison Artillery tasked with defending the new naval base at Scapa Flow, but during the war this role was taken over by the Royal Marine Artillery, and although the Orkney RGA was reformed postwar it was short-lived and disbanded in 1922.[1] [2] [3] [4] [5]
In 1926 it had been decided that the responsibility for coast defences in the UK would rest solely with the part-time Territorial Army (TA). After the Munich Crisis in 1938 there was a rapid expansion of the TA, particularly for coast and air defence.[6] [7] [8] With the Royal Navy's Home Fleet due to be based at Scapa Flow once more if war came, defences for the anchorage were an urgent requirement. The Lord Lieutenant of Orkney and Shetland, Alfred Baikie, took the lead in raising batteries of anti-aircraft and coast artillery and fortress engineers in the islands.[9]
A new Orkney Heavy Regiment, RA was formed on 1 November 1938, comprising regimental headquarters (RHQ) and 190 Heavy Battery at Kirkwall, under the command of Lieutenant-Colonel F. Buchanan. The new unit manned the coast guns at Stanger Head, Flotta, Ness Battery and Stromness, and was supported by the Orkney Fortress Royal Engineers formed at the same time, which were responsible for the searchlights (S/Ls) and generators. Recruiting for these units was good, and they had all attended summer training camps before war broke out on 3 September 1939.[2] [5] [10] [11] [12] [13]
On the outbreak of war the Orkney Heavy Rgt was mobilised to man four 6-inch guns and one 4.7-inch gun.[14]
The entrances to Scapa Flow were supposed to be closed by blockships and booms,[15] but on the night of 14 October 1939 the German submarine U-47 commanded by Günther Prien slipped on the surface between two blockships unseen by the coastal defences and sank the battleship HMS Royal Oak lying at anchor. As a result, the Home Fleet left Scapa Flow until the booms and defences had been improved (including the Churchill Barriers).[16] [17]
After the sinking of Royal Oak the increase in defences of Scapa Flow became a priority. 190 Heavy Bty was split into two units. Then with the threat of invasion after the Dunkirk evacuation, the coastal artillery defending the whole United Kingdom was greatly increased.[6] While the majority of coast defence units were under the local corps or district HQ, the Orkney & Shetland Defences ('OSDEF') came under the control of Anti-Aircraft Command, which had a strong presence on the islands.[18] By July the Orkneys had the following guns emplaced:[19]
On 5 September 1940 the Orkney Heavy Rgt was split into three to man these guns, designated 533rd to 535th (Orkney) Coast Rgts. Later the independent batteries stationed on Shetland were regimented as 1st Coast Artillery Group (later 541st Special Coast Rgt).[2] [12] [5] [20] [21] [22] Given the small local population, most of the manpower for this expansion came from the UK mainland. They were stationed in remote locations on Orkney and Shetland, and during 1941 a programme of rotating batteries with other parts of the UK came into effect.[23]
Responsible for the southern defences in Flotta Fire Command, formed with A, B and C Coast Btys, later organised as:[5] [21] [24] [25] [26] [27]
Responsible for the western defences in Stromness Fire Command, formed with A, B and C Coast Btys, later organised as:[5] [21] [24] [25] [26] [28]
Responsible for the eastern defences in Kirkwall Fire Command, formed with A, B, C and D Coast Btys, later organised as:[5] [21] [24] [25] [26] [29]
There were few changes in the organisation of the Orkney coast defences during the middle years of the war.[30] [31] Then in the spring of 1943 there was another round of exchanges with regiments in the rest of the UK:[21] [32] [33]
533rd (Orkney) Rgt:
534th (Orkney) Rgt:
535th (Orkney) Rgt
(A number of these exchanges were either cancelled or short-term, the batteries returning later.[33])
By 1943 the threat from German attack had diminished and there was demand for trained gunners for the fighting fronts. A process of reducing the manpower in the coast defences began.[34] The manpower requirements for the forthcoming Allied invasion of Normandy (Operation Overlord) led to further reductions in coast defences in April 1944. By this stage of the war many of coast battery positions were manned by Home Guard detachments or in the hands of care and maintenance parties. Many personnel from the regiments on Orkney were transferred to the infantry or to the RA's garrison regiments who carried out occupation duties on the Continent.[35] On 1 April 1944 533rd (Orkney) Rgt lost three batteries:[21] [36] 199 (disbanded), 223 (to 534th (Orkney) Coast Rgt) and 246 (suspended animation)
After VE Day the coast defences were stood down. On 1 June 1945, RHQ of 534th Coast Rgt entered suspended animation at Stromness and its remaining batteries (141, 142, 144, 158, 223, 268) joined 538th (Clyde) Coast Rgt, which acted as a holding unit for Scottish coast batteries, while RHQ of 535th Coast Rgt went into suspended animation at Kirkwall with three batteries (148, 150, 151), the remainder (222, 329, 352) being disbanded.[21] [37] Finally, 533rd Coast Rgt and its remaining batteries (133, 136, 166, 169, 208, 224) were placed in suspended animation on 1 January 1946, together with the ex-Orkney batteries with 538th Coast Rgt.[21] [38]
Postwar discussions on the future shape of the TA had suggested two regiments of coast artillery for Orkney and Shetland, but when it was estimated that the maximum recruitment potential of the two sparsely populated island groups was only 600 men, this was scaled back to a single regiment.[39] Thus, when the TA was reconstituted on 1 January 1947, 534th and 535th Coast Regiments were formally disbanded, while 533rd was reformed as 430 (Orkney) Coast Rgt, RA, renamed 430 (Orkney & Zetland) Coast Regiment on 1 July 1951.[5] [12] [20] [21] [40] [41] It was to be organised as follows:[39]
It formed part of 105 Coast Artillery Brigade, which covered Scotland and Northern Ireland.[39] [41] [42] [43]
The regiment was commanded by Lt-Col J.B. Donaldson, a Regular gunner who was Garrison Commander in Orkney, with Major B.L. Swanney, a TA officer who had served in the Orkney Heavy Regiment, as his second-in-command. By 1951 Maj Swanney had been promoted to the command. At first recruitment was slow, and R and S Btys were not formed until December 1952. The only equipment available for training was the 6-inch guns at Ness Battery, near Stromness, and some twin 6-pdrs. By 1950 a decision had been made to equip some light semi-mobile batteries of coast artillery with the versatile 3.7-inch heavy anti-aircraft gun, which Q Bty trained to operate. By 1954 the regiment was training exclusively on the 3.7-inch gun, including 'landward firing' in a field artillery role.[39]
When the coast artillery branch of the RA was abolished on 31 October 1956,[44] the regiment converted to the light anti-aircraft role and was reduced into 861 (Orkney & Zetland) Independent Light Anti-Aircraft Battery, RA, with its HQ and two Troops at Lerwick, one Troop and the pipe band on Orkney. It trained on the modern L/70 version of the Bofors 40 mm gun, with the associated radar at Lerwick.[5] [12] [40] [41] [45] [46]
On 1 May 1961 the battery was incorporated into 540 (Lovat Scouts) LAA Rgt, becoming Q (Orkney & Zetland) Bty.[5] [12] [40] [41] [45]
From 1947 to 1956 the regiment wore a regimental flash consisting of a small red fouled anchor on a blue disc, derived from the wartime insignia of OSDEF. This was formally authorised in September 1952.[12] [39]
430 Regiment formed a pipe band in 1955, which was officially authorised in 1956 for 861 Bty (the only battery/company/squadron sized unit to be permitted a band). With the permission of Sir Charles Maclean, the band wore Dress Maclean tartan.[39]
Major Sir Basil Neven-Spence, Lord Lieutenant of Shetland, served as Honorary Colonel of 430 Regiment for several years. Unusually for a battery/company/squadron sized unit, 861 Battery was permitted an Honorary Colonel in 1957, and Sir Basil was re-appointed to the role.[46]
