Spring 1918
The heavy casualties suffered by the BEF necessitated a major reorganisation in early 1918. On 1 February, 1/21st Bn was transferred within the division to 140 Bde, where it came under the command of its former CO, now Brig-Gen H.B.P.L. Kennedy. At the same time it received a draft from the disbanded 2/11th London Regiment (Finsbury Rifles) in 58th (2/1st London) Division.[17][20][46][47][48]

The German spring offensive opened on 21 March. The First Surreys had just taken over the 'Welsh Ridge' section of the front at Villers-Plouich, with two companies holding a chain of outposts rather than a continuous trench. After a heavy bombardment and a day of skirmishing with German probes, the battalion was ordered to fall back to 'Highland Ridge' after dark. The following day the battalion's Lewis gun teams fought a delaying action from Welsh Ridge to Highland Ridge. The main German breakthrough had been to the south, and over the next few days the whole division had to fall back because of pressure from this flank. The First Surreys now got separated, part retiring with the rest of the brigade, the remainder with battalion HQ and details of other battalions digging in at Four Winds aerodrome at Lechelle. Later, Brig-Gen Kennedy, organising a mixed force from 47th and 2nd Division had two FSR companies under his command, while battalion HQ and the other companies were part of another mixed force holding the brigade's front line. These outposts were slowly pushed in as the enemy infiltrated between them, and it was not until the evening of 24 March that the battalion was once more concentrated, at Bazentin Wood on the old Somme battlefield. On 25 March the battalion occupied an old trench and caused heavy casualties to German troops pushing past in the direction of Pozieres. Towards evening the enemy infiltration forced the brigade back once more. On 26 March the battalion retired across the River Ancre past fresh troops and ceased to be in the front line. For the next few days the First Surreys were engaged in digging defences, coming under heavy bombardment on 4 April when the rest of 47th Division was attacked once more. The battalion was finally relieved on 8 April.[49][50]
