The 1st East Anglian Division was employed on coast defence until May 1915, when it was concentrated at St Albans preparatory to going overseas as the 54th (1st East Anglian) Division. However, when the infantry departed for the Gallipoli Campaign, the divisional artillery was left behind. In August it joined the 2nd Line at Thetford and Brandon, Suffolk, rearmed with modern 18-pounder guns and handed over its obsolete 15-pounders to the 2nd Line batteries.
