The 11th Medium Regiment was a Royal Artillery unit, formed in the British Army during World War II. First raised in 1940 as infantry of the Essex Regiment, it was converted to the medium artillery role in 1942 and fought in the campaign in North West Europe. It was disbanded after the war.

9th Essex Regiment

On 4 July 1940, as part of the rapid expansion of the British Army after the Dunkirk evacuation, a new 9th Battalion was formed at the Essex Regiment 's depot at Warley Barracks. (A previous 9th (Service) Bn of the Essex Regiment had been formed during World War I as part of 'Kitchener's Army'.)Frederick, pp. 233–5.

After initial training, the battalion (together with 8th Essex Regiment) joined a home defence formation, 210th Independent Infantry Brigade (Home), when it was formed by No 10 Infantry Training Group in V Corps in Southern England on 10 October 1940. On 28 February 1941 the two Essex battalions transferred to 226th Independent Infantry Brigade (Home). At the time this brigade was temporarily attached to 3rd Infantry Division, but on 24 April it was attached to Dorset County Division when that formation became operational in V Corps. As the name implies, the division served in coast defence in South West England. Dorset County Division's brigades were broken up in November 1941, and on 23 November 9th Essex Regiment joined 203rd Infantry Bde in 77th Infantry Division. This division had been formed from Devon and Cornwall County Division as a 'lower establishment' home defence division in VIII Corps in South West England.Joslen, pp. 100, 109, 366, 373, 389.Collier, Maps 17, 20, 27.

On 17 September 1942, the battalion transferred to 219th Independent Infantry Brigade attached to 43rd (Wessex) Infantry Division, but at the end of November that brigade was broken up, and its infantry battalions converted to medium regiments of the Royal Artillery.Joslen, p. 382.

11th Medium Regiment, RA

On 1 December 1942, 9th Essex Regiment officially became 11th Medium Regiment, Royal Artillery with Regimental Headquarters (RHQ) and P & Q Batteries, the batteries being numbered as 85 and 86 Medium Batteries from 1 January 1943. Each battery consisted of eight guns divided into two troops. At the time the RA's medium regiments were re-equipping with new 5.5-inch guns.Ellis, Normandy, Appendix IV.Farndale, Annex M.Farndale, p. 4.Frederick, pp. 722, 731.10th Medium Rgt at RA 1939–45. The new regiment's training was carried out by the experienced 59th (4th West Lancashire) Medium Rgt, by cross-posting half of the personnel of each regiment for three months. 59th Medium Rgt was stationed at Hunmanby in North Yorkshire at this time, with 11th Medium Rgt five miles away at Rudston.Anon, History, pp. 103–7.

After training, the new regiment was assigned to 9th Army Group Royal Artillery (9th AGRA) when that was formed on 1 May. (An AGRA was a brigade-sized group of medium and heavy artillery operating at Corps level.) 11th Medium Rgt attended a practice camp at Redesdale Training Area with 9th AGRA in late May and early June. The AGRA then concentrated in the Northampton area for training, culminating in a series of night marches to Sennybridge Training Area for Exercise Scamper in October. Up to this time, 9th AGRA with its inexperienced regiments had been affiliated to II Corps in Home Forces, but in October 1943 it was assigned 21st Army Group preparing for the Allied invasion of Normandy (Operation Overlord) and moved to Felixstowe. 9th AGRA moved around England as training intensified, to the Brighton area in November 1943, where it trained on the Alfriston ranges on the South Downs, then to Yorkshire in April 1944, where it was training on the Fylingdales ranges when orders arrived to go to its 'Overlord' concentration area in the New Forest.9th AGRA at RA 1939–45.9th AGRA.

Normandy

On 6 July, 9th AGRA was ordered to move next day to London Docks for embarkation. 11th Medium Rgt sailed from South West India Dock under the command of Lieutenant-Colonel M. Yates and landed at Arromanches on 12–15 July. On 17 July 9th and 11th Medium Rgts were sent to Putot-en-Bessin to come under XII Corps, where they fired 9th AGRA's first rounds in support of 43rd (Wessex) and 53rd (Welsh) Divisions' continuing attacks against Évrecy, Maltot and Hill 112 following Operation Jupiter. The regiments were soon firing almost 24 hours a day.

On 28 July, 9th AGRA was ordered to move across to the eastern flank the Normandy beachhead and come under the command of II Canadian Corps. It supported the Canadian attacks south of Caen with fire tasks on enemy strongpoints, counter-battery (CB) and counter-mortar (CM) fire, harassing fire (HF) and defensive fire (DF) tasks. On 8 August the Canadians launched the second phase of Operation Totalize to break out from the beachhead. By 11 August the regiment was at Craménil, firing on Quesney Wood, which was holding up the Canadians, with 11th Medium Rgt working with 4th Canadian Armoured Division. Captain M.A. Searle was the regiment's Forward Observation Officer (FOO) with 28th Armoured Regiment (The British Columbia Regiment (Duke of Connaught's Own)) when he and the squadron commander were ambushed; Searle returned to the regiment three days later, after three failed attempts to escape from the woods in which he was hiding. On 14 August II Canadian Corps launched a new assault (Operation Tractable) and by 16 August the leading troops reached the outskirts of Falaise. 11th Medium Rgt moved up to positions near Sassy on 18 August, firing at targets trapped in the Falaise pocket. By 22 August the whole AGRA was advancing along the corps axis past Vimoutiers as the German defences collapsed. Three days later the guns were pulled out and harboured at Saint-Julien-le-Faucon as the pursuit to the River Seine continued.Buckley, pp. 169–77.Ellis, Normandy, pp. 420–5, 431–2, 441–2, 446–8.Stacey, pp. 222–5, 230–1, 238–43, 248–51.

Channel ports

9th AGRA now came under First Canadian Army and moved up to the coast for the attack on Le Havre (Operation Astonia), but 11th Medium Rgt was sent ahead to Montreuil on 7 September and did not take part. The AGRA then picked up 11th Medium Rgt as it moved to Boulogne for Operation Wellhit by II Canadian Corps, which took from 17 to 22 September. Next came Operation Undergo against Calais, with 11th Medium Rgt supplying a 'pistol gun' for 'sniping' targets. During this operation the German coast batteries at Cap Gris-Nez were firing in enfilade into 9th AGA's gun area, so 11th Medium Rgt was turned to engage them. On 29 September the AGRA supported a small operation by 9th Canadian Bde that swiftly captured the Cap Gris-Nez batteries. The FOO of 11th Medium Rgt captured the command flag of the Haringzelles Battery; this was later forwarded to the Mayor of Dover, which had often been shelled by this battery. Calais surrendered on 30 September.Buckley, pp 193–4.Ellis, Germany, pp. 13–6.Stacey, pp. 331–6, 338–43, 352–4.

Scheldt In early October, 9th AGRA moved across Belgium to join the Battle of the Scheldt. On 7 October its guns fired in support of 7th Canadian Bde establishing a bridgehead over the Leopold Canal (Operation Switchback), then on 9 October helped 9th Canadian Bde over the Savojaards Plaat. On 23 October the group moved to Lamswaarde from where it was possible to fire over the River Scheldt. But to open the vital Port of Antwerp for Allied shipping it was necessary to secure the islands of South Beveland and Walcheren. 9th AGRA supported an amphibious assault by 52nd (Lowland) Division on 26 October, 156th Brigade's attack meeting with initial success but then bogging down. On 28 September 9th AGRA's CB officer with 156th Bde brought down the group's firepower on enemy Flak 88 guns that were troubling the brigade HQ. By 29 October, when 156th Bde linked up with 2nd Canadian Division, which had crossed to South Beveland, 11th Medium Rgt was out of range. 9th AGRA then moved up to IJzendijke to support 155th Bde of 52nd (L) Division in its landing at Flushing (Operation Infatuate) on 1 November. For the next six days the medium guns fired concentrations on call, together with CB and HF tasks throughout the day. The medium guns found the enemy guns in concrete casemates too hard to destroy, while accuracy suffered from the guns being at different heights in the sand dunes. By 6 November the leading troops had entered Middelburg and the regiment was once more out of range.Ellis, Germany, pp. 111–23.Stacey, pp. 393–408, 416–22.

Low countries On 7 November, the whole of 9th AGRA moved just over to Budel to join XII Corps. After reconnaissance, 9th AGRA HQ and 11th Medium Rgt moved up to Weert ready for Operation Mallard to begin at 16.00 on 14 November. This was carried out by XII Corps to clear the enemy from the west bank of the River Maas and by 17 November there was only a small pocket left at Roermond. On the morning of 20 November all the guns of 9th AGRA fired their first rounds across the river onto German soil. On 30 November 9th AGRA went to Bilzen to join XXX Corps and then on 8 December moved to Munstergeleen, where the spread of the gun positions was such that 11th Medium Rgt was placed temporarily under the tactical command of 5th AGRA. XXX Corps was preparing for Operation Shears to breach the Siegfried Line, but this was cancelled when the Germans counter-attacked in the Ardennes (the Battle of the Bulge); instead the medium and heavy guns carried out a CB programme against all known enemy gun positions along the corps front. 9th AGRA remained in defensive mode under XII Corps during December while XXX Corps was diverted south to help block the German advance. At this time 11th Medium Rgt was deployed just inside the German frontier, about north east of Brunssum. The guns fired at targets of opportunity, such as small German counter-attacks that probed the front.Buckley, pp. 239–40, 259–61.Ellis, Germany, pp. 160, 179, 184.Essame, pp. 184–92.Horrocks, pp. 236–41.

In the new year, XII Corps carried out Operation Blackcock to clear the Roer Triangle between Roermond and Geilenkirchen. The start was postponed by bad weather, but it went ahead on 16 January 1945 with sequential attacks by 7th Armoured, 43rd (Wessex) and 52nd (Lowland) Divisions; 9th AGRA fired in support of all three divisions, firing concentrations on enemy defences and gun areas. Progress was slow because of strong resistance and the appalling weather (though some air observation post (AOP) flights were possible), but the triangle was virtually clear by 26 January, and by the end of the month there were no German troops west of the River Roer.Buckley, pp. 265–8.Ellis, Germany, pp. 241–7.Essame, pp. 195–201.Lindsay & Johnstone, pp. 108–23.
