Designed by Charles Sargeant Jagger (1885-1934) and dedicated in 1925, the memorial is in the form of a giant sculpture of a BL 9.2 inch Mk I howitzer upon a large plinth of Portland stone, with stone reliefs depicting the reality of war.
There are four bronze figures of artillery soldiers on the memorial as part of scenes reflecting the reality of war.
Jagger's Royal Artillery Monument is unusual in that the sculptor took a realist approach to his figures, going against the idealised style of other sculptures of the time. The three upright bronze figures stand at ease, rather than to attention; one artilleryman even leans back against the parapet, his cape hanging over his outstretched arms, suggesting an attitude of exhaustion or contemplation. One of the artilleryman reads letters from home, a similar subject to Jagger's Great Western Railway War Memorial in Paddington Station.
Jagger's memorial is also noteworthy in that it depicts the body of a dead soldier. During the war years, a government edict had banned images of dead British soldiers; Jagger defied this censorship by including the body of an artilleryman, laid out and shrouded by a greatcoat, his helmet placed on his chest. Underneath is are inscribed the words Here was a Royal fellowship of Death from Shakespeare's Henry V.
When questioned about his lifelike depictions, Jagger remarked to the Daily Express newspaper that the "experience in the trenches persuaded me of the necessity for frankness and truth".
In 1949, three bronze panels (by Darcy Braddell) were added in memory of the 30,000 of the Royal Artillery killed in World War II.
The memorial's main inscription reads:
'In Proud Remembrance Of The
Forty-Nine Thousand & Seventy-Six
Of All Ranks Of The
Royal Regiment of Artillery
Who Gave Their Lives for King
And Country in the Great War
