After the failure of British attacks at Neuve Chapelle and the French in Champagne, the Germans attacked at the Second Battle of Ypres on 22 April. By this time the territorial battalions of the regiment had just landed in France with the 50th (Northumbrian) Division on 17–18 April. Without any 'nursery' period the brigades of the Division were deployed as needed in the northern part of the salient around St Julian and the Gravenstafl Ridge. Repeated German attacks throughout late April and May forced a withdrawal toward Ypres. Between 25 and 27 April, the 8th battalion was reduced to the effective strength of one company after being enfiladed at Boetleer's Farm with the 8th Canadian battalion and is credited with saving the flank of the 85th Brigade. In late May, the 5th, 7th, 8th and 9th battalions were part of the forces that slowed the German assault on the Bellewaarde Ridge the last battle of Second Ypres. Due to its losses, in June, the 8th battalion was merged with the 6th battalion to form the 6th/8th Composite battalion, which separated back into its components in August after reinforcement.
