12. The Reserve Artillery Brigade in England had already been reorganised in December 1916. The 18 pounder batteries were reorganised in January. Because the divisions were each a howitzer battery short, the reorganisation of howitzer batteries had to await the arrival of the new 116th, 117th, 118th, 119th and 120th Field Artillery (Howitzer) Batteries in March. These were then disbanded, and the last of the howitzer batteries reorganised by 2 April 1917.
