As part of the 129th Brigade, both the 4th and 5th Wiltshires participated in the Battle of Normandy, landing in France on 24 June 1944. On arrival in theatre, the division became part of Lieutenant-General Sir Richard O'Connor's VIII Corps. Both battalions would be heavily engaged in many battles during the campaign across North-West France, the low countries, and Germany. During the Normandy Campaign, this included the Battle of Odom, the fight for Hill 112 (Operation Jupiter), and the capture of Mont Picon.
