Army Group Royal Artillery
An Army Group Royal Artillery was a British Commonwealth military formation type during the Second World War and shortly thereafter, generally assigned to corps. An AGRA was mainly composed of medium artillery regiments but heavy regiments and field regiments were also used. They were moved at need from corps to corps within an army.
They were created during the war as artillery theory evolved. After the British Expeditionary Force was expelled from France in 1940, the need for flexibility in the control of artillery above the division increased. As the British Army manpower shortage developed, the weight of fire that an AGRA could add to an attack was becoming increasingly important. The idea was to group all artillery above the division in formations which could be switched within the field army at will to meet needs for fire concentration on different parts of the front. For the most part each corps in the line was assigned an AGRA but when especially heavy fire support was needed one corps area could be stripped of its AGRA to support another as happened at the battle for Calais in 1944, or in the initial attack on the Italian mainland when two AGRAs, side-by-side, fired across the Straits of Messina, from Sicily.
AGRAs made their debut in the Mediterranean Theatre of Operations and the concept was further used during Operation Overlord and the ensuing campaigns.
Commonwealth AGRAs
Canadian corps-level concentrations of artillery were also referred to as AGRAs, despite the fact they were composed of units of the Royal Canadian Artillery and Royal Artillery regiments.[1] Canada had two AGRAs in the Second World War, one served in Italy as part of I Canadian Corps and NW Europe from March 1945 and the other only in Northwest Europe with II Canadian Corps.[2]
