To mark the 70th anniversary of Victory in Europe day, our Portsmouth site Fort Nelson will be firing the impressive 25 pounder self-propelled gun at 1pm and 3pm today. Also known as the Sexton, the gun was developed to support rapidly advancing forces in later stages of World War Two. The gun will be fired at at 1pm and 3pm today.
The Royal Artillery experimented with a number of designs in their attempted to improve the mobility of artillery. Self-propelled guns on tracked mountings gave much better cross-country mobility. The ‘Flanders Mud’ of the First World War made it difficult and sometimes impossible to move heavy guns. Early tanks showed the way forward, leading to the gradual introduction of self-propelled guns [SPGs]. The towed 25 pr gun, examples of which can be seen on display in the Voice of the Guns gallery and the Artillery Hall, required a towing vehicle and limber and had limited off-road ability.
Early prototypes included the ‘Bishop’, combining a mounted 25 pounder quick firing gun to chassis of a Valentine tank. The Royal Artillery also used the American M7 self-propelled 105 mm which was known as the ‘Priest’, as its gun mounting resembled a pulpit. However, the British needed a self-propelled gun which incorporated the 25 pounder.
The answer, which came to be known as the Sexton, was created by adapting a Canadian Kangaroo chassis, based on the M3 American tank, to carry a 25 pounder field gun. Manufactured at the Montreal Locomotive Works in Canada, over 2150 Sextons were produced between 1943 and 1945.
This example on display at the Royal Armouries at Fort Nelson is painted in the colours of the 90th City of London Yeomanry, which landed in Normandy on D–Day, 6 June 1944. On the final run into the beaches they fired their guns from the landing craft in support of the troops already ashore. This example was transferred to Portugal after the Second World War and reimported in the 1980s and has been restored to running order
