By the time of its introduction, the sword was of limited use on the battlefield against rapid-firing rifles, machine guns and long-range artillery. However, the new sword was regarded, when needed, as a very effective fighting weapon. Reports from the Sudan, where it was used in close-quarters fighting during the reconquest of the Sudan (1896-'99) were positive. Officers carried swords into battle in 1914 at the start of the First World War, and some were still being used in action at the Battle of Neuve Chapelle in March 1915. That June, Army Order 68 prohibited the carrying of swords by infantry on the battlefields of the European theater of the war, in an effort to prevent officers making themselves conspicuous to the enemy; however, at least one sword was carried in the assault on the first day of the Battle of the Somme in June 1916. Bernard Montgomery advanced with his 1897 pattern sword drawn during a counteroffensive in October 1914; having never received any training on how to use it. The actual sword he carried is exhibited in the Imperial War Museum, London.
