63rd (2nd Northumbrian) Division

The 63rd (2nd Northumbrian) Division of the British Army was a second-line Territorial Force division, formed in 1914, which served on home defence duties during the First World War. The division was formed as a duplicate of the 50th (Northumbrian) Division in 1914, composed primarily of soldiers recruited in north-eastern England. It remained on home defence and training duties in the north-east and east of England until 1916, when it was disbanded. Several of its constituent units would later serve overseas, deployed for support and garrison duties in almost every theatre of the war.

History
The division was created as the "2nd Northumbrian Division", a second-line formation of the Northumbrian Division at the end of August 1914. At this time, Territorial Force soldiers could not be deployed overseas without their consent and the Territorial units were split into a "first line", with men who had volunteered for overseas service and a "second line", which was intended for home service only. The second line units also served to absorb the large number of new recruits who had joined the Territorial Force following the outbreak of war. The division's units formed through late 1914 and assembled in the Sunderland–Newcastle area, where it was responsible for coastal defence.

As with the original Northumbrian Division, the 2nd Northumbrian was organised into three infantry brigades. These were later numbered as the 188th (2/1st Northumberland) Brigade, composed of the 2/4th, 2/5th, 2/6th, and 2/7th Northumberland Fusiliers, the 189th (2nd York and Durham) Brigade, composed of the 2/4th East Yorkshire Regiment, the 2/4th and 2/5th Yorkshire Regiment (Green Howards) and the 2/5th Durham Light Infantry and the 190th (2nd Durham Light Infantry) Brigade, composed of the 2/6th, 2/7th, 2/8th and 2/9th Durham Light Infantry.

The 188th Brigade recruited from Newcastle and Northumberland, the 189th from the North and East Ridings of Yorkshire and the 190th entirely from County Durham. The division also raised second-line Territorial artillery, medical signal and engineer units from the same areas. While it did not contain any organic mounted units, it had two cavalry brigades attached at formation, the first-line Scottish Horse Mounted Brigade and the second-line 2/1st Welsh Border Mounted Brigade, as well as the first-line 1/1st East Riding of Yorkshire Yeomanry. The Officer Commanding was Andrew Becher, who had commanded a brigade of the original Northumbrian Division before the war.

Through the next two years, the 2nd Northumbrian, numbered as the 63rd Division in 1915, provided drafts of trained men for the 50th Division as well as carrying out home defence duties. On 20 May 1915, it was paraded at Newcastle to be inspected by King George V and Queen Mary. The following day, the East Yorkshire Yeomanry was moved south to join 1st Mounted Division. In July, the strength of its infantry battalions was set at a maximum of 600 men, with any more than this being transferred overseas, in August the Scottish Horse Brigade was shipped to Gallipoli, where it served as dismounted infantry. The division moved south to Nottinghamshire in November, where Major-General George Forestier-Walker, who had returned home after commanding a division on the Western Front, took command in February 1916. The 63rd began to disband in May 1916, and ceased to exist in July, with some units remaining independent for several months before being broken up or transferred to new divisions. Forestier-Walker formally remained in command until 8 September.

Four battalions were posted to overseas garrison duties, the 2/7th Northumberland Fusiliers to Egypt, the 2/4th East Yorkshires to Bermuda and the 2/5th and 2/9th Durham Light Infantry to Salonika. The remaining infantry units were transferred to the new 71st Division, 72nd Division and 73rd Divisions, all home-service units. The 2/7th Durham Light Infantry later served with the Allied force in the North Russia Intervention. The artillery was transferred to the Royal Naval Division in France, the engineers to the 15th Indian Division in Mesopotamia and the medical units to Salonika.

The divisional number was almost immediately reused for the 63rd (Royal Naval) Division, which was formed from the un-numbered Royal Naval Division on 19 July 1916 and its brigades were renumbered as the 188th, 189th and 190th Brigades. Prior to the Second World War, on the doubling of the Territorial Army, the second line duplicate of the 50th (Northumbrian) Infantry Division was numbered as the 23rd Division, after the Kitchener's army predecessor (as were the attached brigade, the 69th and 70th), not the 63rd, that division number and subsidiary brigades were not reused in the War.
