Kitchener's Army battery that had originally been raised for the 11th (Northern) Division. The division was warned to prepare for embarkation to the Western Front. On 17–18 May the artillery brigades were converted to the establishment adopted by the BEF: 2/VIII Bde was numbered CCCIII Brigade (303 Bde), 2/21st London Bty left to become D (H) Bty in CCC (formerly 2/V London) Bde, and 2/22nd London Bty became D (H) Bty in CCCII (formerly 2/VII London) Bde. 3/1st, 3/2nd and 3/3rd Wessex Btys, which had earlier joined the other brigades in the division, became A, B and C Btys, and the former 4/LX Bty became D (H). The BACs were also abolished before the division went overseas. CCCIII Brigade therefore had no remaining London units in its organisation: A (formerly 3/1st Wessex) Bty – 4 x 18-pdrs B (formerly 3/2nd Wessex) Bty – 4 x 18-pdrs C (formerly 3/3rd Wessex) Bty – 4 x 18-pdrs D (H) (formerly 4/LX) Bty – 4 x 4.5-inch Western Front On 14 June 1916 orders arrived for 60th (2/2nd L) Division to embark, and the artillery units made the crossing from Southampton to Le Havre between 22 and 26 June, with CCCIII Bde under the command of Lt-Col N. Bayley. The division concentrated in the area behind Arras by 29 June. It relieved 51st (Highland) Division in the line on 14 July, with the artillery moving into position over the next three nights. The line held was facing the same strong German positions along Vimy Ridge that 47th (2nd L) Division had faced, and there was constant mine warfare and trench raiding. The artillery was mostly engaged in suppressing troublesome German trench mortars (Minenwerfers) by firing short concentrated bombardments on specific sectors of the enemy line. Some trench raids were preceded by local wire-cutting bombardments, or by a barrage, others were 'stealth' raids. On 30–31 August the divisional artillery underwent the same reorganisation into six-gun batteries that was going on throughout the BEF. In CCCIII Bde this meant half batteries joining from CCC Bde, which was being broken up. However, orders arrived on 1 November for the division to transfer to the Macedonian front (Salonika), where the four-gun establishment was still in force, and the batteries reverted to their original organisation; the former sections from CCC Bde left and formed a composite B/CCC Bty, which remained in France as an instructional battery at First
