30th (Howitzer) Brigade Royal Field Artillery
It was originally formed with 128th, 129th and 130th (Howitzer) Batteries, each equipped with 4.5" howitzers, and attached to 3rd Infantry Division. In August 1914, it mobilised and was sent to the Continent with the British Expeditionary Force, where it saw service with 3rd Division until broken up.
In May 1916, the artillery brigades of infantry divisions were reorganised; the pure howitzer brigades were disbanded, and their batteries attached individually to field brigades, in order to produce mixed brigades of three field batteries and one howitzer battery. Accordingly, the brigade was broken up and the batteries dispersed; 128th to 29th Brigade, 129th to 42nd Brigade, and 130th to 40th Brigade.
- The basic organic unit of the Royal Artillery was, and is, the Battery. When grouped together they formed brigades, in the same way that infantry battalions or cavalry regiments were grouped together in brigades. At the outbreak of World War I, a field artillery brigade of headquarters (4 officers, 37 other ranks), three batteries (5 and 193 each), and a brigade ammunition column (4 and 154) had a total strength just under 800 so was broadly comparable to an infantry battalion (just over 1,000) or a cavalry regiment (about 550). Like an infantry battalion, an artillery brigade was usually commanded by a Lieutenant-Colonel. Artillery brigades were redesignated as regiments in 1938.
