Mobilisation The East Anglian Division was a week into its fortnight's annual training at
Clacton when the order to mobilise arrived on 4 August 1914. The units immediately proceeded to their designated war stations defending the East Anglian coast, with 7th Essex at
Felixstowe. They were relieved on 9 August to return to Walthamstow to mobilise, and by 10 August the division was concentrated around
Brentwood, Essex, with 7th Bn HQ at the
Golden Fleece Inn. The 7th later moved to the cavalry barracks in
Norwich, and then
Costessey Hall. In August 1914 the Essex Brigade formed a Service Battalion of volunteers from all four battalions. This was put at 24 hours' notice for service in France, but was stood down in November and the men returned to their battalions. Meanwhile, all TF units were forming '2nd Line' units composed of recruits and those men who had not volunteered for Overseas Service. The Essex recruits were only asked to volunteer for overseas service after they were attested, and many opted for Home Service only. Thus the 2/7th Bn (as this reserve unit became known) was fully up to strength whereas the parent battalion (designated 1/7th) remained below establishment. The East Anglian Division was designated the
54th (East Anglian) Division in May 1915, and its brigades were numbered, the Essex Brigade becoming
161st (Essex) Brigade. The 2nd Line units were assigned to duplicate formations, the 2/7th Essex joining
206th (2nd Essex) Brigade in
69th (2nd East Anglian) Division. During the war, 161 Brigade adopted shoulder flashes coloured red and black, divided vertically, with the red worn to the front on each arm. Each battalion adopted a distinctive shape for this patch, the 1/7th Bn wearing a square.
1/7th Battalion The 54th Division was part of
Central Force, the mobile force organised for Home Defence, and was employed on coast defence with 1/7th Bn at
Colchester until May 1915, when the division concentrated around
St Albans to prepare for overseas service. On 8 July it heard that it was to be employed at
Gallipoli. 161st Brigade sailed from
Devonport, Devon, with two companies of 1/7th Bn embarked in
HMT Southland departing on 24 July and the remainder in the SS
Braemar Castle on 26 July. The two vessels rendezvoused at
Imbros on 10 August and the battalion landed on 'A' Beach at Suvla Bay after midnight on 11/12 August.
Gallipoli The Gallipoli Campaign had been in progress for several months and had reached stalemate. A fresh
Landing at Suvla Bay on 6 August 1915 was intended to turn the flank of the Turkish positions on the Gallipoli Peninsula and drive inland. The operation was bungled, and 54th Division, as the last remaining reserve, was landed to drive through, but was used merely to shore up the position. The Essex battalions arrived still understrength, and armed with obsolete long
Lee–Enfield rifles – many soldiers exchanged these for modern
SMLE weapons picked up from casualties. 1/7th Essex went straight into the reserve line when 161 Bde relieved
163rd (Norfolk & Suffolk) Brigade for an attack. 161 Brigade's participation was cancelled, but on the afternoon of 14 August the brigade advanced over open ground to relieve the Norfolks and Suffolks after their disastrous attack. The Essex Brigade's historian records that 'Though they were met with a fusillade as they advanced steadily over the plain there was no hesitation'. They reached the line and spent all night consolidating the position, the 1/7th having suffered 25 casualties during the advance. On 17/18 August the brigade relieved the
10th (Irish) Division at Kiretch Tepe, the 1/7th Bn taking over 'Jephson's Post'. Intermittent shellfire on these positions caused considerable casualties before the battalion was relieved on 22 August. The brigade then moved to the Lala Baba sector, and from 1 to 10 September interchanged with parties of the
4th Australian Brigade. A Company of 1/7th was attached to Australian troops at 'Table Top', B Company went to 'Rhododendron Spur', and the remainder of the battalion worked on a new communication trench. Next the battalion moved to the
Hill 60 sector, described by one of the officers as 'notoriously one of the most unpleasant spots on the peninsula'. It was attached to 163 Bde to prepare for an attack to capture the rest of the hill, where opposing trench lines were only 17 yards apart and sappers on both sides were digging
mines. The operation was repeatedly postponed: even though the 1/7th Essex was the strongest battalion in 163 Bde, its battle casualties were running at about 50 a month and a much higher proportion were sick in hospital. 1/7th Battalion did receive a draft of 2 officers and 70 other ranks in early November, but it was not enough. The already debilitated brigade was too weak to mount even a smaller attack. The British mines were finally fired on 14 November and a 100-strong party of the 1/7th Bn was tasked with seizing the crater, but the trenches were obstructed by debris and the attack was called off. On 24 November a Turkish mine exploded under 'Essex Barricade', killing 8 and wounding 10 of the battalion. On the night of 26/27 November, the Essex were relieved by
Gurkhas and the
New Zealand Mounted Rifles Brigade, the relief being delayed by a severe rainstorm that flooded the trenches. After a few days in the rest area, 54 Division marched down to the beach and embarked for
Mudros on 4 December. It did not return to the peninsula, which was later evacuated, and instead the division sailed to
Alexandria.
Egypt As soon as it arrived in Egypt, the battalion became involved in the
Senussi Campaign when 161 Bde marched out on 28 December to replace the
New Zealand Rifle Brigade guarding the coast railway from Alexandria to Da'aba. The Essex battalions were relieved from this duty on 4 March 1916 by the
2nd County of London Yeomanry and moved into the No 1 (Southern) Section of the
Suez Canal Defences. In August the battalion was moved northwards to counter a Turkish thrust at the canal, and was present at the
Battle of Romani, though not engaged.
Sinai and Palestine During 1916, the units of 54th Division were steadily brought up to strength by the arrival of drafts, and in mid-January 1917 the division assembled for the opening of the
Palestine Campaign. It took the whole of February for 161 Bde to cross the
Sinai Desert in stages. It was then involved in all three Battles of Gaza, in March, April and November 1917. At the
First Battle of Gaza (26 March 1917), the main attack was made by
53rd (Welsh) Division with 161 Bde in support. Towards the end of the day the Essex Brigade was ordered to take Green Hill: despite heavy fighting the attack was a complete success and the brigade held the whole position by nightfall. However, confusion set in, and 53rd Division withdrew during the night. The men of 161 Bde were enraged by the order to withdraw. The following day patrols showed that the Turks had not reoccupied the position; 1/7th Bn was sent up to support the patrols, but a violent Turkish counter-attack finished the battle. The battalion's casualties at Green Hill were 228, of whom 68 were missing after the fighting withdrawal. For the
Second Battle of Gaza (17–19 April 1917) 1/7th Bn was detached from 161 Bde and was assigned to the
Imperial Camel Corps (ICC), which was protecting the left flank of 54th Division. On 16 and 17 April the 1/7th Essex was escorting artillery. On 19 April the battalion remained with the Hong Kong and Singapore Battery in support of the ICC's morning attack, and then at 10.30 pushed forward to help the right flank of 3rd (Australian) Camel Bn when the Australian Light Horse retired. When the 1/7th Essex withdrew it had suffered casualties of only 2 killed and 7 wounded, while the rest of 54th Division was badly cut up in the failed main assault. During the summer months 161 Bde held the line without suffering serious casualties, and by the end of October the 1/7th Bn was fully up to strength for the forthcoming
Third Battle of Gaza (1–3 November 1917). On the morning of 2 November the 54th Division put in a holding attack at the El Arish Redoubt. The fighting was confused, but the division took all its objectives. However, the 1/7th Bn found that the fourth objective, 'John Trench', was a mere scrape in the ground and could not be held. The brigade commander considered that this battalion had the hardest time of all that day. At 04.00 on 3 November, 1/7th made a renewed attempt to take their objective, but were again held up by Turkish machine-gun fire. The battalion's casualties over the three days were heavy, at 281 all ranks. During the rapid pursuit after the fall of Gaza, 1/7th was left marching in the rear. As well as battle casualties, the whole brigade suffered considerably from
influenza during November–December 1917 and throughout 1918. The weakened brigade was mainly engaged in line-holding until September 1918. 54th Division was held in readiness to move to reinforce the
Western Front, but in the end was not sent. 54th Division returned to the offensive for the
Battle of Megiddo (19–25 September 1918), which finally broke the Turkish resistance. To support the breakthrough, 161 Bde was to secure the Es Zakur line and then form a defensive flank. The brigade formed up before dawn on 19 September, with 1/7th Bn in the second line. Covered by an overhead barrage from the machine gun companies, the first line took the two objectives successfully, with platoons of 1/7th close up in support. The main assault completely broke through the Turkish lines and opened the way for the cavalry to pursue the defeated enemy. 161 Brigade was left behind for a week on battlefield clearance before joining the pursuit. By the time the
Armistice with Turkey was signed on 30 October 1918, 54th Division had reached
Beirut.
Demobilisation Soon after the Armistice, 54th Division moved back to Egypt by sea. By the end of the year, with men returning from hospital, the 1/7th Bn was well over its establishment strength. Preparations for demobilisation began, but civil unrest in Egypt meant that 161 Bde was engaged in peacekeeping duties from March to May 1919. After June the duties became very light and demobilisation proceeded. 1/7th Battalion was reduced to a
cadre on 9 July and absorbed by 1/5th Bn. It was formally disembodied on 29 August and the whole Essex Brigade was fully demobilised by Christmas 1919.
2/7th Battalion The 2/7th Essex Bn began forming at Walthamstow on 11 August 1914, initially comprising those members of the parent unit who had not volunteered for overseas service, together with recruits under training. At first the battalion only had
.256-in Japanese Ariska rifles with which to train. By December it was at
Peterborough, and in early summer 1915 at
Thetford. When the Home Service men were removed to form Provisional Battalions, the 2/7th was particularly badly hit and could barely raise a company of men available for overseas service. In 1916 it was brought up to strength with
Derby Scheme men and expected to be sent overseas, but instead it continued to provide drafts to other battalions. It served in
206th (2/1st Essex) Brigade in
69th (2nd East Anglian) Division on Home Defence at
Harrogate (July 1916), then from April 1917 at
Welbeck. This continued until 10 October 1917 when the battalion was transferred to
201st (2/1st Middlesex) Brigade in
67th (2nd Home Counties) Division, with the battalion quartered in
The Granville Hotel, Ramsgate. It was broken up on 25 March 1918, the remaining men going to the 4th Reserve Bn.
3/7th Battalion The 3/7th Bn was formed at Walthamstow on 7 May 1915 to act as a reserve for the 1st and 2nd Bns. It moved to
Windsor Great Park with the other Essex Regiment 3rd Bns in August that year, and then to
Halton Park in October. In April 1916 its title was altered to 7th Reserve Bn Essex Regiment, and on 1 September it was absorbed by the 4th Reserve Bn.
17th Battalion In 1915 the 'Home Service-only' and unfit men of the TF were formed into Provisional units for home defence. The Essex Regiment formed three such battalions, with the men of 7th Bn and some of 5th Bn forming 67th Provisional Battalion in
3rd Provisional Brigade. In 1915 3rd Provisional Bde was attached to
69th (2nd East Anglian) Division in the area around
Thetford,
Norfolk,
Newmarket and
Bury St Edmunds in
Suffolk. In March 1916 the brigade came under
Northern Army in Norfolk, where 67th Provisional Bn was stationed at
Cley next the Sea. When the
Military Service Act 1916 swept away the Home/Overseas Service distinction, all TF soldiers became liable for drafting overseas if medically fit, and the provisional battalions became numbered battalions of their parent regiments on 1 January 1917. 67th Provisional Battalion became
17th Battalion, Essex Regiment at
Sheringham, moving to
Weybourne by July, while 3rd Provisional Brigade was redesignated
223rd Brigade. The battalion was disbanded at
Holt, Norfolk, on 17 March 1919. ==Interwar==
