 However, unlike, most Territorial divisions which formed an exact 'mirror' duplicate of 2nd Line units, the 43rd (Wessex) was instead split on a geographical basis.The units from Dorset, Wiltshire and Hampshire remained with the 43rd Division and units from Devonshire, Somerset and Cornwall joined the 45th Infantry Division.Therefore, the newly raised 7th Hampshire Regiment and the 4th Dorset Regiment were both transferred to the 130th Infantry Brigade.
