The 3rd Anti-Aircraft Division was an air defence formation of the Territorial Army, part of the British Army, created in the period of tension before the outbreak of the Second World War. It defended Scotland and Northern Ireland during the early part of the war.

Origin

Large numbers of Territorial Army (TA) units were converted to anti-aircraft (AA) and searchlight roles in the Royal Artillery (RA) and Royal Engineers (RE) during the 1930s, and higher formations were required to control them. The 3rd AA Division was the first division-level headquarters created de novo (earlier ones being converted infantry divisions). It was formed at Edinburgh on 1 September 1938 within Scottish Command, transferring to Anti-Aircraft Command when that formation was created on 1 April 1939. It was responsible for the AA defences of Scotland, including Northern Ireland and the Orkney and Shetland Defences (OSDEF). It operated with No 13 Group of RAF Fighter Command, covering Scotland and the North of England.[2][3]

Order of battle

The composition of the 3rd AA Division on the outbreak of war was as follows:[3][4]

Mobilisation

Mobilisation in the last week of August 1939 was difficult for the 3rd AA Division, which had the task of moving troops, guns and stores by road and by sea to remote and inaccessible sites in Orkney to defend the fleet anchorage at Scapa Flow, which had high priority.[34]

At this point the division had a strength of 111 HAA guns, while in the LAA role there were 18

Bofors guns, and 340 light machine guns (LMGs), together with 159 searchlights.[35] The HAA guns were deployed in the defended areas as follows:[36]

Shortly afterwards, Tyneside and Teesside became the responsibility of a new the 7th AA Division, and the 3rd AA Division was able to concentrate on defending Scotland.[35]

Phoney War

Unlike most of Britain's defence forces, the 3rd AA Division was frequently in action during the so-called Phoney War that lasted from September 1939 to May 1940. The first action occurred unexpectedly on 16 October 1939, when nine enemy aircraft suddenly appeared out of cloud and dived on warships off Rosyth Dockyard, close to the Forth Bridge. No warning had been given, but gun positions of the 71st HAA Rgt hastily loaded for a 'crash' action under individual gun control, normal prediction being impossible against diving and turning targets. A total of 104 rounds were fired and one aircraft had its tail shot off (fighters accounted for another two). HMS Southampton was damaged. The following day, 14 hostile aircraft in three waves attacked warships lying in Scapa Flow. The 226th Battery of the 101st HAA Rgt was able to engage and claimed one shot down. Among the vessels damaged in this raid was the Jutland veteran HMS Iron Duke, acting as a base ship and floating AA battery.[37]

These attacks led to calls for strengthened AA defence for the naval bases at Scapa Flow, Invergordon, Rosyth and the Clyde anchorage, and the 3rd AA Division was given priority for new guns. Starting in January 1940, the division was to receive 64

Gun layers were blinded by gun-flashes in the half light. No enemy aircraft were brought down. A subsequent inquiry concluded that the low level attack had evaded radar, the gun lay-out still left gaps in the perimeter, and guns were out of action awaiting spare parts.[38]

There were three more attacks on Scapa Flow the following month. On 4 April, a formation estimated at 12 Ju 88s carried out a series of medium- and low-level runs, dropping bombs and machine-gunning AA positions, and escaped without loss. Four days later, 12

Norway and France and the Low Countries[39]

In November 1939, the 3rd AA Brigade HQ and some of its units were sent to France with the British Expeditionary Force, defending the lines of communication.[40][41][42] The 3rd AA Brigade HQ returned to Northern Ireland after the Dunkirk evacuation.[43][44]

Battle of Britain

On 11 July 1940, at the start of the Battle of Britain, the guns of the 3rd AA Division under the command of Maj-Gen Leslie Hill were deployed as follows:[45]

  • Belfast – 7
  • Clyde – 28
  • Ardeer
    – 4
  • Kyle of Lochalsh – 4
  • Aberdeen – 4
  • Scapa Flow – 88
  • Shetlands – 12
  • Airfields – 8
  • Vulnerable Points – 119 (mainly Bofors gun)

The 3rd AA Division was now cooperating with Fighter Command's No 14 Group, recently reformed to cover Scotland.

In 1940, the Royal Artillery's AA regiments were designated 'Heavy AA' (HAA) to distinguish them from the newer Light AA (LAA) units. (Prior to that, some of the Regular Army and Supplementary Reserve regiments had included both HAA and LAA batteries.) Also during 1940, all the searchlight units, whether AA battalions of the RE or still forming part of their parent infantry regiments, were transferred to the RA. The units of the 52nd AA Brigade were therefore redesignated as follows:

  • 51st (Highland) Searchlight Regiment, RA – from January 1940[46][47]
  • 52nd (Queen's Edinburgh, Royal Scots) Searchlight Regiment, RA – from August 1940[48][49]
  • 56th (Cameronians) Searchlight Regiment, RA – from August 1940[20][50]
  • 57th (Glasgow) Searchlight Regiment, RA – from August 1940[22][51]

In September 1940, the 3rd AA Division formed the 3rd AA Z Regiment, equipped with Z Battery rocket projectiles.[52]

In November 1940, at the height of

III AA Corps,[53] and the 3rd AA Division's commander, Maj-Gen Hugh Martin, was promoted to command the new higher formation.[3]

Blitz

From November 1940 and during The Blitz, the 3rd AA Division's order of battle was therefore as follows:[54][55][56][57][58]

  • 36th AA Brigade Edinburgh & Forth
    • 71st HAA Rgt – as above; left October 1941
    • 114th HAA Rgt – formed November 1940[57][59]
    • 31st LAA Rgt – as above
    • 32nd LAA Rgt – as above
  • 51st AA Brigade NE Scotland
  • 52nd AA Brigade Searchlights
    • 51st S/L Rgt – as above
    • 52nd S/L Rgt – as above
    • 56th S/L Rgt – as above
  • 3rd AA Z Rgt
  • 3rd AA Divisional Signals, RCS
  • 3rd AA Divisional RASC
    • 195th and 225th Companies
  • 3rd AA Divisional Company, Royal Army Medical Corps
  • 3rd AA Divisional Workshop Company, RAOC
  • 3rd AA Divisional Radio Maintenance Company, RAOC (joined during 1941)

Mid-war

After December 1941 the division's order of battle was as follows:[63][64]

36th AA Brigade

51st AA Brigade

52nd AA Brigade

  • 51st S/L Rgt – left and became the 124th (Highland) LAA Regiment February 1942[47][57][66]
  • 52nd S/L Rgt – became the 130th (Queen's Edinburgh, Royal Scots) LAA Regiment March 1942 and remained with brigade[49][57][67]
  • 56th S/L Rgt – left and became the 125th (Cameronians) LAA Regiment in February 1942[20][57][68]
  • 147th HAA Rgt – formed February 1942[57]
  • 67th LAA Rgt – joined from the 51st AA Brigade Spring 1942; left June 1942
  • 135th LAA Rgt – joined from the 36th AA Brigade Spring 1942

'Mixed' indicates that women of the Auxiliary Territorial Service (ATS) were integrated into the unit.

The increased sophistication of Operations Rooms and communications was reflected in the growth in support units, which attained the following organisation by May 1942:[64]

  • 3rd AA Division Mixed Signal Unit HQ, RCS
    • HQ No 1 Company
      • 2nd AA Division Mixed Signal Office Section
      • 403rd AA Gun Operations Room Mixed Signal Section
      • 7th AA Sub-Gun Operations Room Mixed Signal Sub-Section
      • 8th AA Sub-Gun Operations Room Mixed Signal Sub-Section
      • 36th AA Brigade Signal Office Mixed Sub-Section
      • 203rd RAF Fighter Sector Sub-Section
      • 341st AA Gun Operations Room Mixed Signal Section
      • 8th AA Line Maintenance Section
    • HQ No 2 Company
      • 51st AA Brigade Signal Office Mixed Sub-Section
      • 210th RAF Fighter Sector Sub-Section
      • 343rd AA Gun Operations Room Mixed Signal Section
      • 52nd AA Brigade Signal Office Mixed Sub-Section
      • 204th RAF Fighter Sector Sub-Section
      • 336th AA Gun Operations Room Mixed Signal Section
      • 3342nd AA Gun Operations Room Mixed Signal Section
      • 340th AA Gun Operations Room Mixed Signal Section
      • 9th AA Line Maintenance Section
  • HQ 3rd AA Div RASC
    • 192nd, 255th Companies
  • 3rd AA Div Workshop Company, RAOC
  • 3rd AA Div Radio Maintenance Company, RAOC

The RAOC companies became part of the new Royal Electrical and Mechanical Engineers (REME) during 1942.

Disbandment

In August 1942 the Divisional HQ moved south to join

I AA Corps and assist in controlling the large number of AA units brought in to defend against Luftwaffe 'hit and run' attacks on the South Coast of England.[69] It was given control of the 27th (Home Counties), 47th and 64th AA Brigades, but this lasted only for a short time, because AA Command underwent a major reorganisation at the end of September 1942, resulting in the disbandment of all the AA Divisional HQs.[2][54][64][70][71] In October 1942, the 3rd and th12 AA Divisional Signals re-merged to form the 6th AA Group Signals.[33]

General Officers Commanding

The commanders of the 3rd AA Division were as follows:[3][72]

  • Major-General Lancelot Hickes, from formation until 23 September 1939
  • Major-General Leslie Hill, 24 September 1939 – 13 August 1940[73]
  • Major-General Hugh Martin, 14 August–10 November 1940 (promoted to command III AA Corps)[74]
  • Major-General John Younger, 15 November 1940 (from the 4th AA Division) to 7 January 1942 (posted to Washington)[75]
  • Major-General William Wyndham Green, DSO, MC*, 7 January 1942 until disbandment (posted to the 5th AA Group)[76]
