Mobilisation Units of the East Lancashire Division had been on their annual training when war came: on 3 August they were recalled to their drill halls and at 17.30 next day the order to mobilise was received. The men were
billeted within reach of their drill halls while the mobilisation process went on.
1/II East Lancashire Brigade On 20 August the East Lancashire Division moved into camps around
Bolton,
Bury and
Rochdale, and on 5 September it received orders to go to
Egypt to complete its training and relieve Regular units from the garrison for service on the
Western Front. It embarked on a convoy of troopships from
Southampton on 10 September, the first TF division to go overseas. However, only two brigades of its divisional artillery accompanied it, and 1/II East Lancs was one of those left behind, spending the next few months in Manchester. 1/II East Lancs Bde did not reach
Alexandria until 14 June 1915, by which time the rest of the East Lancashire Division (now designated 42nd (East Lancashire) Division) had been landed at
Cape Helles on the
Gallipoli Peninsula. The brigade remained in Egypt until the remnants of the division returned from the
Gallipoli campaign in January 1916. 42nd (EL) Division concentrated at Mena Camp on 22 January before moving into the southern sector of the
Suez Canal defences. On 27 February the brigade was rearmed with modern
18-pounder guns handed over by
29th Division as it left for the Western Front. On 31 May 1916 1/II East Lancs Bde was numbered
CCXI (211) Brigade, RFA, and the batteries designated A, B and C. The canal defences were situated east of the waterway, with a string of self-contained posts, each garrisoned by an infantry battalion and an artillery battery. The division did much of the construction and trained in the desert, the gunners carrying out field firing with their new guns. The gun wheels were fitted with 'ped-rails' to assist movement across soft sand, for which 12 rather than 6 horses were harnessed to gun-carriages and limbers. In late July the division was ordered north, where a
Turkish column was advancing on the defences. CCXI Brigade was stationed at El Ferdan. The Turkish force was defeated at the
Battle of Romani near
Pelusium on 4–5 August, after which 42nd (EL) Division set off in pursuit. The men and horses suffered badly from lack of water, but the Turks lost heavily. The division then returned to the canal posts, with A Bty of CCXI Bde at Pelusium. For the next few months the division was part of the
Desert Column covering the extension of the railway and water pipeline into the
Sinai Desert to permit the
Egyptian Expeditionary Force to mount an offensive into Palestine. The head of the Desert Column reached
El Arish, near the Palestine frontier, on 22 December. On 25 December 1916 CCXI Bde was renumbered CCXII (exchanging numbers with the former 1/III East Lancs (Bolton Artillery)) and was reorganised, with C Bty being split between A and B to bring them up to six guns each. The two Manchester batteries fought with their new brigades in 42nd (EL) Division for the rest of the war on the Western Front, including the operations on the Flanders coast in 1917, the defence against the
German Spring Offensive in March 1918, and the
Allies' final
Hundred Days Offensive.
2/II East Lancashire Brigade The 2nd Line units of the East Lancashire Division were raised in September and October 1914, with only a small nucleus of instructors to train the mass of volunteers. Training was slow because the 2nd Line artillery lacked guns, sights, horses, wagons and signal equipment. The
2nd East Lancashire Division, now numbered 66th (2nd EL) Division, began concentrating in
Kent and
Sussex in August 1915. 2/II East Lancs Bde was given four old
French De Bange 90 mm guns for training, but passed these on to
69th (2nd East Anglian) Divisional Artillery in October and it was not until December that it received its 18-pdrs. In September Lt-Col Francis Hill transferred from the
IV East Lancashire (Howitzer) Bde to take command of the 2/II. In early 1916 the division moved into the East Coast defences, with its artillery at
Colchester. In May 1916 the brigade was numbered as
CCCXXXI (331) Brigade and the batteries designated A, B and C. The division's howitzer brigade (2/IV East Lancs) was broken up, and 2/1st Cumberland (Howitzer) Bty joined CCCXXXI Bde as D (H) Bty, equipped with
4.5-inch howitzers. 66th (2nd EL) Division's training suffered long delays caused by having to find reinforcement drafts for 42nd (EL) Division. Supplying one draft of 250 gunners in 1916 considerably delayed the whole division; these then had to be replaced by drafts from the 3rd Line (in the case of 2/II East Lancs Bde these came from 3/II East Lancs Bde at
Southport and later
Whitchurch, and from the brigade's administrative centre at Manchester). The division was finally ready for overseas service at the end of 1916. Before leaving England the brigade's batteries were made up to 6 guns each and a section of the former 2/2nd Cumberland (H) Bty joined from CCCXXXII Bde to bring D (H) Bty up to six howitzers, giving the final organisation of the brigade: • A Bty (2/15th Lancashire Bty) – 6 × 18-pdr • B Bty (2/16th Lancashire Bty) – 6 × 18-pdr • C Bty (2/17th Lancashire Bty) – 6 × 18-pdr • D (H) Bty (2/1st + half 2/2nd Cumberland (H) Bty) – 6 × 4.5-inch
Ypres 66th (2nd EL) Division was ordered to France on 11 February 1917 and CCCXXXI Bde entrained on 11 March for Southampton, where it embarked for
Le Havre. The division concentrated under
First Army and CCCXXXI Bde's batteries went into the line around
Cambrin. The artillery covered a number of trench raids by the division, but otherwise the front was quiet. In July the division moved to
Nieuport on the Flanders Coast where British troops were being concentrated for a planned thrust up the coast in conjunction with the
Third Ypres Offensive. However, the Germans launched a spoiling attack, and the expected breakthrough at Ypres failed to materialise, so the operation was cancelled. Lieutenant-Col Hill left the brigade in July and Maj H.B. O'B. Traill, a regular RGA officer, was transferred in and promoted to succeed him. 66th (2nd EL) Division was relieved by 42nd (EL) Division in October and went to the
Ypres Salient. The road congestion and the mud on the Passchendaele ridge was so bad that the batteries could not all get up to their intended positions: only C Bty got into action in time to support the division's attack on 9 October (the
Battle of Poelcappelle). The barrage was weak, and shells buried in the mud did no damage. The division's attack, in heavy rain, made little progress. After the infantry of 66th (2nd EL) Division were relieved on 11 October, the guns remained in position. They were regularly under fire, and the ammunition had to be brought up by pack-horses. CCCXXXI Brigade supported the attacks by
II ANZAC Corps on 12 October (the
First Battle of Passchendaele) and
Canadian Corps on 26 October (the
Second Battle of Passchendaele). The gunners were finally relieved by
2nd Canadian Division, who took over their guns in position on 27 October. 66th Divisional Artillery then rallied at the waggon lines, taking over the Canadian guns, and marched to rest billets at
Le Doulieu on 31 October. The brigade had suffered casualties of 8 killed and 65 wounded in the month. It went back into the line on 11 November, relieving Australian gunners. The final attack on Passchendaele had been made the previous day, but the guns remained under shell and gas attack on the open slopes. Major R.J. Adams was promoted to take command of CCCXXXI Bde at the end of the month. Next day the Germans again attacked under cover of mist, and were through the Brown Line by midday. The division withdrew towards the Green Line. By now some reinforcements had arrived, including
50th (Northumbrian) Division, which manned the Green Line as the 66th passed through. Lieutenant-Col J. Laird of CCCXXX Bde was now given command of 'Left Group' of field artillery covering the left half of
XIX Corps, consisting of what remained of 66th DA (two of his own btys, with A, C (3 guns) and D (5 howitzers) Btys of CCCXXXI Bde), and other nearby RFA and
Royal Horse Artillery units. Lieutenant-Col Adams with CCCXXXI Brigade HQ went back to the wagon lines to take charge of the withdrawal of the transport. That night the surviving units of XIX Corps, slipped away from the meagre defences of the Green Line and joined the 'Great Retreat' towards the
Somme Canal. The heavy artillery and transport began crossing the canal next morning, with Laird's group coming into action at
Cartigny and then
Le Mesnil to support the infantry rearguards before crossing itself and taking up positions at
Barleux. On 26 March the Germans forced their way across the canal and the retreat was resumed. On 28 March 66th DA crossed the
River Somme. Here the division's infantry were relieved, but 66th DA fired in support of 'Carey's Force', a scratch force of engineers that held the line at
Villers-Bretonneux, where the retreat ended on 29 March. 66th (2nd East Lancashire) Division disappeared from the war for many months, its surviving infantry units becoming training
cadres for newly-arrived American troops, but 66th DA continued as an independent artillery force. By now XIX Corps had assigned its available field artillery to cover particular sectors, regardless of the formation to which they belonged. On 30 March Lt-Col Adams took command of a group comprising C Bty of CCCXXXI Bde (6 guns) with C Bty (6 guns) and part of D Bty (2 howitzers) from CCCXXX Bde, with his HQ in Villers-Bretonneux and the batteries deployed around the station. Next day Adams' Group was joined by D/CCCXXXI Bty (4 howitzers) and A/CCCXXX Bty (4 guns), while the rest of his brigade was under Laird. During the
Battle of the Avre (4 April) 66th DA (temporarily commanded by Lt-Col Adams) supported
18th (Eastern) Division, and was heavily shelled. Communications were cut so runners had to be used, and some of the batteries had to be pulled back into Villers-Bretonneux, but they achieved good results, their SOS fire stopping one attack just short of the positions of
35th Australian Battalion attached to 18th (E) Division. CCCXXXI Brigade was now organised into three four-gun batteries (B, C and D) under the command of Maj Grice-Hutchinson. 66th DA was relieved on the night of 7/8 April. Between 21 March and 13 April CCCXXXI Bde had suffered casualties of 4 officers and 35 other ranks (ORs) killed, 6 officers and 96 ORs wounded, and 3 officers and 31 ORs missing (mainly
Prisoners of war). On 16 April 66th DA was sent north by train to
Second Army which was fighting the
Battle of the Lys. From 20 April it formed a single composite brigade under Lt-Col Laird, with C and D Btys manned by CCCXXXI Bde. It supported
36th (Ulster) Division until 26 April, then concentrated in the
Proven area to reorganise, with the batteries returning to their own brigades. With no infantry to support, the trench mortar batteries and the Small Arms Ammunition Section of the Divisional Ammunition Column were disbanded, releasing gunners and drivers to reinforce the gun batteries. By the end of the month all the batteries were back to their six-gun strength. From 14/15 to 22 May 66th DA was in action near Busseboom supporting counter-attacks by the 14th French Division, and in June and early July it covered small operations by various formations in Second Army. XIX Corps HQ then moved into the area and assigned 66th DA to support
27th US Division (which had no artillery of its own) under training in the East
Poperinghe Line or 2nd Position. After a short spell in the front line when 66th DA relieved
41st Divisional Artillery for an operation near
Kemmel, 66th DA returned to the East Poperinghe Line and briefly joined
30th US Division. By now 66th (2nd EL) Division had been reformed as a fighting division and had fought at the battles of
Cambrai and the
Selle in XIII Corps, covered by the artillery of other formations. It now came up from reserve and took up the advance. On 5 November A and C Btys of CCCXXXI Bde, each with a howitzer section from D Bty, crossed the canal at
Landrecies to provide close support to
198th (East Lancashire) and
199th (Manchester) Infantry Bdes respectively as they followed the retreating Germans. The rest of CCCXXXI Bde moved up over the next two days. On 9 November Fourth Army formed a pursuit force under the commander of 66th (2nd EL) Division,
Major-General Keppel Bethell. 'Bethell's Force' comprised
5th Cavalry Bde and the
South African Bde, with A, B and two sections of D (H) Btys from CCCXXXI Bde under Lt-Col Adams, together with
Royal Air Force (RAF) squadrons, armoured cars, anti-aircraft guns, cyclists, machine gunners, engineers and pioneers, and support services. While Bethell's force continued pursuing the beaten Germans, the remainder of Fourth Army halted to ease its supply problems. The rest of CCCXXXI Bde supported 199th Bde around
Avesnes. On 10 November Bethell's Force picked its way forward with single field gun sections accompanying the South African advance guard. Cavalry patrols found the enemy deployed just beyond
Hestrud. The South Africans attacked, coming under fire from artillery, machine guns and aircraft, but captured the high ground, while the RAF attacked the retreating German transport column. Following, CCCXXXI Bde HQ moved up to
Solre-le-Château, where the Germans had abandoned its ammunition trains and dumps. That night the Germans shelled the station, attempting to destroy the ammunition. Early next morning, 11 November, 199th Bde sent forward two battalions, each with two 18-pdrs, to drive off the enemy's screens. Hostilities ended at 11.00 that day when the
Armistice with Germany came into force. Having led the pursuit, 66th (2nd EL) Division was initially selected to form part of the Army of Occupation, and began its march to the
Rhine on 18 November. However, the march was halted on 1 December, when CCCXXXI Bde had reached
Philippeville in Belgium. On 14 December the division went into winter quarters around
Ciney while other formations went to form
British Army of the Rhine. CCCXXXI Brigade remained billeted at
Havelange while demobilisation began. This process was completed on 4 May 1919 when the brigade was disbanded. ==Interwar==
