Mobilisation When war was declared on 4 August 1914, the Denbighshire Hussars mobilised at their drill halls under the command of Lt-Col H.P. Sykes, a retired RegularArmy captain who had been in command since 21 December 1910. The regiment assembled with the WBMB and then went with it to its war stations in
East Anglia. In accordance with the
Territorial and Reserve Forces Act 1907 (
7 Edw. 7, c.9) which brought the TF into being, it was intended to be a home defence force for service during wartime and members could not be compelled to serve outside the country. However, on 10 August 1914 the TF was invited to volunteer for overseas service. On 15 August the War Office issued instructions to separate those men who had signed up for Home Service only, and form these into reserve units. On 31 August, the formation of a reserve or 2nd Line unit was authorised for each 1st Line unit where 60 per cent or more of the men had volunteered for Overseas Service. The titles of these 2nd Line units would be the same as the original, but distinguished by a '2/' prefix. In this way duplicate battalions, brigades and divisions were created, mirroring those TF formations being sent overseas. Later, the 2nd Line was prepared for overseas service and a 3rd Line was formed to act as a reserve, providing trained replacements for the 1st and 2nd Line regiments.
1/1st Denbighshire Hussars The 1/1st Welsh Border Mounted Brigade joined the
1st Mounted Division in September 1914. It was stationed around
Bungay, moving to
Beccles in February 1915. The brigade was dismounted in November 1915 and thereafter the regiments acted as infantry. Early in 1916 the 1/1st Welsh Border and 1/1st
South Wales Mounted Brigade left 1st Mounted Division and were sent to
Egypt, disembarking at
Alexandria on 15 March. As soon as they arrived, on 20 March, they were amalgamated to form the
4th Dismounted Brigade. At first this brigade was placed in the
Suez Canal defences under
53rd (Welsh) Division, with 1/1st Denbighshire Hussars at Moghara, but in April it came under the command of
Western Frontier Force (WFF). The brigade was with the
Suez Canal Defences when, on 14 January 1917,
Egyptian Expeditionary Force (EEF) Order No. 26 instructed that the
2nd,
3rd and 4th Dismounted Brigades be reorganised as the
229th,
230th and
231st Infantry Brigades. On 23 February, the
General Officer Commanding the EEF,
Lieutenant-General Sir A.J. Murray, sought permission from the
War Office to form the 229th, 230th and 231st Brigades into a new division. On 25 February, the War Office granted permission and the new
74th (Yeomanry) Division started to form. The 231st Brigade joined the division at
Khan Yunis on the border of
Palestine on 10 April.
24th (Denbighshire Yeomanry) Battalion, Royal Welch Fusiliers Meanwhile in February 1917 the dismounted Yeomanry regiments comprising the new division were converted into numbered battalions of an infantry regiment recruiting from the same area. Thus on 1 March 1/1st Denbighshire Hussars became
24th (Denbighshire Yeomanry) Battalion of the
Royal Welch Fusiliers. 74th (Y) Division took part in the
Sinai and Palestine campaign in 1917–18. It was in reserve for the
Second Battle of Gaza (17–19 April 1917) and then saw action at the
Third Battle of Gaza (27 October–7 November) including the
Capture of Beersheba (31 October), where 24th RWF led the attack on the Turkish positions, and the
Capture of the Sheria feature (6 November). It took part in the
Capture of Jerusalem (8–9 December) and its subsequent defence (27–30 December). Early in 1918 it fought in the
Battle of Tell 'Asur (8–12 March). The
German spring offensive in March 1918 led to an urgent call for the EEF to supply reinforcements for the
British Expeditionary Force (BEF) on the
Western Front,. On 3 April 1918, 74th (Y) Division was warned that it would move to
France and by 30 April 1918 had completed embarkation at Alexandria. 24th RWF landed at
Marseille in early May. The division then began training for the battle conditions of the Western Front. Due to a lack of replacements, British infantry divisions on the Western Front had been reduced from 12 to nine battalions at the beginning of 1918. To conform with this new structure, one battalion left each brigade of 74th (Y) Division, 24th RWF being the battalion selected from 231st Bde. On 21 June the three battalions were used to reconstitute
94th Brigade of
31st Division, which was renamed the 94th (Yeomanry) Brigade on that date. The battalion remained with 94th (Y) Bde in 31st Division for the rest of the war, taking part in the Action of Le Becque (28 June), the Capture of
Vieux-Berquin (13 August) and the Final Advance in Flanders, including the
Fifth Battle of Ypres (28 September–2 October) and the Action at
Tieghem (31 October). After a period in reserve, the division was pushing forward through
Belgium from
Avelghem to
Renaix when the
Armistice with Germany came into force on 11 November. On 31 March 1916, the remaining Mounted Brigades were ordered to be numbered in a single sequence and the brigade became
17th Mounted Brigade, still in Northumberland under
Northern Command. In April 1916, it left 63rd (2nd N) Division and moved with its brigade to
East Anglia where it joined the 1st Mounted Division, replacing its 1st Line, which had left (dismounted) for Egypt. By July it had moved with its brigade to the
Morpeth, Northumberland area. In July 1916 there was a major reorganisation of 2nd Line yeomanry units in the United Kingdom. All but 12 regiments were converted to
cyclists and as a consequence the regiment was dismounted and the brigade converted to
10th Cyclist Brigade in 1st Cyclist Division (the former 1st Mounted Division). Further reorganisation in October and November 1916 saw the division broken up and the brigade redesignated as
6th Cyclist Brigade in November, still in the Morpeth area. At this time the regiment departed for the
1st Cyclist Brigade at
Beccles in
Suffolk where it was amalgamated with the
2/1st Montgomeryshire Yeomanry as the
3rd (Denbigh and Montgomery) Yeomanry Cyclist Battalion. The regiment resumed its separate identity as
2/1st Denbighshire Hussars in March 1917. It moved to
Worlingham (near Beccles) in July, to
Aldeburgh in January 1918 and back to Worlingham in April. The battalion disbanded at Beccles on 29 October 1918.
3/1st Denbighshire Hussars The 3rd Line regiment was formed in 1915 and in the summer it was affiliated to a
Reserve Cavalry Regiment at
The Curragh. In the summer of 1916 it was dismounted and attached to the 3rd Line Groups of the
55th (West Lancashire) Division as its 1st Line was serving as infantry. The regiment was disbanded in about February 1917 with the personnel transferring to the 2/1st Denbighshire Hussars or to the 4th (Reserve) Battalion of the
Royal Welsh Fusiliers at
Oswestry. ==Interwar==
