The headlong advance ended with the failure of
Operation Market Garden at
Arnhem, and emphasis shifted to bringing the port of Antwerp into use as a supply base. The planners envisaged a large Gun Defence Area (GDA) to deal not only with conventional air raids but also the threat of
V-1 flying bombs (codenamed 'Divers'). 76th AA Brigade's move to Antwerp finally occurred in mid-October, the brigade being relieved by 80th AA Bde at Boulogne, while 125th LAA Rgt and 1617th Platoon RASC temporarily left to join
107th AA Bde in the
Siege of Dunkirk. 76th AA Brigade's intended deployment area was still in enemy hands, so 112th and 113th HAA Rgts operated in the ground role supporting
II Canadian Corps in clearing the south side of the
Scheldt Estuary (the
Battle of the Scheldt), with the Canadian gun lines protected by 120th LAA Rgt and 557th S/L Bty. When the brigade had overcome flooding and minefields to take up its positions on the islands of
Walcheren and
South Beveland, its guns engaged German units escaping by boat from Walcheren, and supported
4th Commando Brigade's continuing operations on
North Beveland. Once secure, the GDA covering the whole area of Antwerp and the estuary was established, with 76th AA Bde responsible for the Scheldt North zone. HAA positions were established at intervals of 4–5000 yards along the waterway, interspersed with irregularly sited LAA positions.
2nd S/L Rgt arrived direct from England with the primary task of cooperating with the LAA guns against mine-laying in the channel. The brigade also formed a local warning radar troop from its own resources. By December, the brigade had the following units under command: •
98th HAA Rgt (joined 16/17 November) • 112th HAA Rgt • 113th HAA Rgt • 120th LAA Rgt •
124th (Highland) LAA Rgt (joined 16/17 November) • 125th LAA Rgt • 2nd S/L Rgt (joined 17 November) • 152 AAOR • No 1 Local Warning (Radar) Trp (formed 27 November) • 323 Artillery Coy RASC (1506, 1540, 1617, 1618, 1651 & 1652 Artillery Platoons) On 19 December, 98th HAA Rgt was transferred to the US 50th AA Artillery Brigade to assist in the 'Diver' defence belt, and the rest of the North Scheldt guns had to be redeployed to fill the gap. The only enemy aircraft seen in this period were on reconnaissance missions, usually flying very high, but on 8 December the brigade scored its first 'kill' since arriving in the area, when A Trp of 362/113th HAA Bty destroyed a
Junkers Ju 188 picked up on radar and then illuminated by searchlight. When the German Army launched its Ardennes offensive (the
Battle of the Bulge) aimed at breaking through to Antwerp, 76th AA Bde was ordered to take precautions against possible attacks by German airborne troops, as well as dealing with increased air activity at night. After that, enemy air activity was sparse, but on 9 January, four Bofors of 411/124th LAA Bty hit and sank a German
Biber midget submarine operating off South Beveland. Two others were destroyed later, one by Bofors, one by 3.7-inch guns of 113th HAA Rgt, together with a manned torpedo. In mid-February, 76th AA Bde HQ took over local administration of the Scheldt islands from 4th Commando Bde. Apart from coastal defence and occasional ground fire tasks, particularly against enemy positions on
Schouwen, much of the early part of 1945 was taken up with unit training to use the new
SCR-584 radar and No 10 Predictors (the all-electric
Bell Labs AAA Computer) for HAA guns, and new No 2 Mark VIII searchlight control (SLC) radar. The brigade also cooperated with the Royal Navy, using
GL Mk III gunlaying radar to direct landing craft making a raid on Schouwen on the night of 11/12 March. In March and April, the brigade lent a platoon of its
AEC Matador HAA gun tractors to 21st Army Group to assist in transporting engineering stores for the assault crossing of the
Rhine (
Operation Plunder). This included towing Bren carriers full of stores, and heavy sledges normally moved by
Armoured Vehicle Royal Engineers. As the war in Europe drew to its close, AA commitments in rear areas were reduced and units closed up to the Scheldt, where they were either sent forward into Germany (as AA or occupation troops) or prepared for disbandment. 113th and 146th HAA Regiments, 114th and 139th LAA Regts were all disbanded in April 1945, 98th HAA Rgt was converted into garrison troops, and 103rd HAA Rgt was converted into a driver training regiment. 76th AA Bde's order of battle in the final weeks of the war was as follows: •
86th (Honourable Artillery Company) HAA Rgt • 99th HAA Rgt • 120th LAA Rgt • 411/124th LAA Bty • 125th LAA Rgt •
1st S/L Rgt (less one bty) On 9 April 1945 Brig Benson left to become Commander RA (CRA) for
52nd (Lowland) Division and was replaced by Brig E.J.C. Chaytor, and later by Brig J.C. Friedberger, former CRA of
53rd (Welsh) Division. The brigade was ordered to cease fire on 3 May 1945 when a local truce came into effect to allow supplies to be sent to civilians in enemy-occupied Holland (
Operation Manna). This was followed on 4 May by the
German surrender at Lüneburg Heath and the end of the war in Europe (
VE Day). ==Occupation duties==
