Michèle Barrett, The Guardian, Saturday April 19, 2003:
In 1925, Charles Sargeant Jagger’s monument for the Royal Artillery, at Hyde Park Corner, set off another round of letters to the Times. Commissioned by soldiers, and executed by an artist who was a decorated war veteran, the stone Howitzer gun on top caused problems for pacifist civilians. Most controversial of all was Jagger’s inclusion of a sculpture of a dead Tommy. The figures on three sides of the memorial had been long planned – there was to be a driver, an officer and of course a gunner – but the fourth side was described in terms of “a feature in bronze”. At a late stage in the proceedings, thereby minimizing the inevitable objections, Jagger revealed that this was to be a “recumbent figure”, a dead artilleryman covered by a heavy military coat.
