At last on June 3 1803 Shrapnel was given the opportunity of demonstrating his shell before a Committee of Field Officers of Artillery, who approved it for service. Two months later he was ordered to the Carron Ironworks (near Falkirk, Scotland) to supervise its manufacture. Although officially termed 'spherical case' the original projectiles were called 'shrapnel' by the Gunners who fired them, and the name stuck. They were simply hollow cast iron spheres filled with a mixture of balls and powder, and fuzed with a crude time fuze, but they increased the effective range of case from 300 to about 1100 metres.
Shrapnel was promoted Major on 1 November 1803 after eight years as a Captain. Records indicate the new weapon was first used at the Batavian settlement of Surinam on 30 April 1804 against the Dutch who surrendered after the opening rounds, so impressive was the effect. Shrapnel was promoted Lieutenant Colonel on 20 July the same year; people in high places were beginning to notice him.
Although few, if any, historians mention the fact, a great deal of credit was due to Shrapnel's projectiles over the next decade for defeat of the French, who were never able to develop an answer to them. However, in recognition of his contribution to the 'state of the art' the British Government in 1814 awarded him £1200 a year for life.
Although generally successful the early versions of shrapnel gave some trouble. Owing to friction between the balls and the powder of the filling, prematures sometimes occurred, so the first modification was to place the powder in a separate container (Fig. 2).

A further improvement was made in 1840 by inserting an iron diaphragm between powder and balls (Fig. 3). Both these improvements were due to Captain EM Boxer RA and were later incorporated into cylindrical shell for rifled ordnance (Fig. 4 and 5).

Shrapnel eventually rose to the rank of Lieutenant General on 10 Jan 1837 and died on 13 March 1842. He is a past Colonel-Commandant Royal Artillery, having been appointed to that office on 6 March 1827. In 1852, following a request from Shrapnel's family, the British Government ordered that spherical case henceforth be known officially as 'shrapnel' in honour of its inventor - and 'shrapnel' it has remained ever since.
Although true shrapnel projectiles have been obsolete since 1935, the term 'shrapnel' is still used in a sense not technically correct to describe what should properly be defined as 'splinters' or 'fragments'.
Manufacture of Armstrong's RBL guns ceased in 1864 (but those already made stayed in use for 20 years) and in what is now regarded as a retrograde step both Army and Navy reverted to rifled muzzle-loading (RML) ordnance until 1880 when they again adopted breech-loaders. From Figure 5 it can be seen that construction of RML shrapnel shells was almost identical to that of Armstrong, and they functioned in the same way.
