In 1917, an important change took place when many Royal Field Artillery Brigades were removed from the division under whose command they had been, to be converted into “Army Brigades”. This essentially created a pool of such units, which could be allocated to corps or divisions as operational needs required. It enabled a massing of artillery resources where needed and was an important element in the development of the war-winning army. For researchers, however, it makes life a little more difficult.
Although the war diaries of the Army Brigades have survived, they are at a detailed day-to-day level and it can be difficult to extract context: for example, in which battles did a given Army Brigade participate? The following tables will help the researcher identify the division and corps under which a brigade came at any time, and by reference to that division and corps pages on the Long, Long Trail it will be straightforward to identify the battles.
The tables are taken from document WO95/5494 at the National Archives (Crown Copyright)
If the brigade you are researching is not listed here, it is because it was not one of the units that converted into Army Brigades.
