Researching a man from this battalion? See my WW1 Research page.

This battalion was formed on 7th September 1914 by Lieutenant Colonel Claude Lowther MP and Committee. The principal recruiting offices were located at:

Bexhill on Sea






Some 1,100 men enlisted in 56 hours.

All original enlistments were given an "SD" (South Downs) prefix to their regimental number.

The original composition of the Battalion was:

A Company : Eastbourne double company.

B Company : Eastbourne, Bexhill and Hastings.

C Company : Worthing, Herstmonceux, Horsham and Newhaven.

D Company : Bognor and Chichester.


Training took place at Cooden Camp, near Bexhill, from September 1914 until July 1915. At this stage the War Office took over direct control of the battalion and it moved to Detling Camp, near Maidstone in Kent. On 29th September 1915 the battalion moved to North Camp, Aldershot. In October it became part of 116th Brigade, 39th Division. This division had been formed at Winchester in August 1915, but concentrated at Witley via Aldershot in October/November 1915. From this date until March 1916, the battalion stayed at Witley Camp.

It crossed to France via Southampton on 5th/6th March 1916, landing at Havre.

It served on the Western Front with 116th Brigade, 39th Division until the Spring of 1918. Following heavy losses in the German Offensive of March/April 1918 the battalion was reduced to a training cadre on 23rd May 1918. It moved to Boulogne as part of the 25th Division on 30th June 1918, and then crossed to England. The battalion was reformed at Aldershot, moved to Deal (Kent) and absorbed other Royal Sussex Regiment personnel and the 13th Battalion Royal West Kents. At this stage it was part of the 75th Brigade, 25th Division. On 9th September 1918 this unit became the 236th Brigade and left the 25th Division, sailing from Dundee to North Russia on 17th October 1918. After service here, it returned to England in mid-1919 and was finally disbanded.
