33rd (Western) Anti-Aircraft Brigade
The 33rd (Western) Anti-Aircraft Brigade was an air defence formation of Anti-Aircraft Command of the Territorial Army, part of the British Army, formed shortly before the outbreak of the Second World War. It defended Merseyside and West Lancashire during The Blitz. Origin

Phoney War and Battle of Britain
During the early part of the war the brigade's searchlight regiments were transferred to other formations and were replaced by new HAA and Light Anti-Aircraft (LAA) regiments. By the end of the Battle of Britain 33 AA Bde had the following units under command:
 103 HAA Regiment – formed May 1940
 106 HAA Regiment – formed August 1940

The Blitz
While the Battle of Britain raged over the skies of Southern England by day, there were also night raids on industrial cities, and Liverpool was heavily attacked for four nights in a row from 28 August. The night raids continued into the following Spring, during which period the city and its docks along the Mersey became the most heavily bombed area of Britain outside London. The campaign became known as the Liverpool Blitz, with particularly heavy attacks at Christmas 1940 (the Christmas Blitz), in April 1941, and again in May (the May Blitz). Order of Battle 1940–41
By the end of the Blitz the brigade had the following units under command:

Mid-War

The Blitz ended in May 1941, but occasional raids continued. Newly formed units joining AA Command were increasingly 'mixed' ones into which women of the Auxiliary Territorial Service were integrated. Some of these were armed with Z Battery rocket projectiles that were partly manned by members of the Home Guard. At the same time, experienced units were posted away for service overseas. This continual turnover of units accelerated in 1942 with the preparations for Operation Torch and the need to relocate guns to counter the Baedeker Blitz and the Luftwaffes hit-and-run attacks against South Coast towns.

Order of Battle 1944
In March 1944 the number of brigade HQs in 4 AA Group was reduced, and 33 AA Bde HQ was temporarily given additional responsibilities until these units were redistributed, mainly to the south of England to cover the embarkation ports for Operation Overlord:

By October 1944, AA Command was being forced to release manpower to 21st Army Group fighting in North West Europe and 33 AA was reduced to one HAA regiment (157th; replaced by 169th – 566, 571, 576 (M) HAA Btys – in December) and its three AA Area Mixed regiments. At this date its own HQ establishment was 9 officers, 8 male other ranks and 25 members of the ATS, together with a small number of attached drivers, cooks and mess orderlies (male and female). In addition, the brigade had a Mixed Signal Office Section of 5 male other ranks and 19 ATS, which was formally part of the Group signal unit. War's end
As the war neared its end there was a continued run-down of AA Command: 4 AA Group was disbanded in mid-March 1945, and 33 AA Bde transferred to the command of 5 AA Group. By this time, the brigade consisted solely of the rocket batteries of the three AA Area Mixed Rgts, and as these were disbanded in April. were disbanded during March and April, the brigade HQ soon had nothing to command. In May 1945, after the end of the war in Europe (VE Day), it was given control of 12 Area AA Maintenance HQ to administer the demobilisation process, with 37th (Tyne Electrical Engineers) and 69th (3rd City of London) S/L Rgts added in June. By November it was commanding a number of returned Regular Army units, together with others awaiting demobilisation:

On 1 January 1947, 33 AA Bde's Regular Army units reformed 9 AA Bde in Wales, while the TA portion was renumbered as 59th Anti-Aircraft Brigade in the reformed TA, constituting  part of 4 AA Group based at Warrington:

AA Command was disbanded on 10 March 1955 and there was a series of reductions and mergers in the TA's AA units. 59 AA Brigade was itself placed in suspended animation on 31 October 1955 and formally disbanded  on 31 December 1957. A new brigade
A new 33rd AA Bde was formed on 1 November 1955 at Shepherd's Bush, London, by redesignation of X AA Bde (formerly 63 AA Bde). It had no links with Western Command or Merseyside. This brigade was reorganised on 1 May 1961, becoming 33 Artillery Brigade in 56th (London) Division. Foot
