In early April the Division was warned that it would go on overseas service and entrainment began on 16 April. By 23 April the Division had concentrated in the area of Steenvoorde. It had arrived just as the German army had attacked at nearby Ypres, using poison gas for the first time, and was rushed into the battle. The Division then remained in France and Flanders and took part in the following engagements:

The Silver War Badge was given to those invalided out, to wear as a reminder to others as to why they weren't actually serving. I.E. they weren't to be branded as cowards!
