Conception

The La Hitte system was developed through the collaborative work of Lieutenant-colonel Treuille de Beaulieu
Antoine Treuille de Beaulieu
Antoine Hector Thésée Treuille de Beaulieu was a French General of the 19th century, who developed the concept of rifled guns in the French Army. He studied the subject of rifling between 1840 and 1852. Following a request by Napoleon III in 1854 to develop such a weapon, the de Beaulieu system...

. These guns were a considerable improvement over the previous smooth-bore guns which had been in use. They were able to shoot at 3,000 meters either regulars shells, ball-loaded shells or grapeshot. They appear to have been the first case of usage of rifled cannons on a battlefield.

The system was muzzle-loading, and the shells could only be exploded at two set distances. The shell, based on the 1847 invention of Captain Tamisier, were oval-shaped and had small protrusions to follow the grooves of the bore. Previous guns, such as the Canon obusier de 12

 were rifled to accommodate the system. The system included newly rifled siege guns of 12, 16 and 24, new field guns of 4 and 12, new siege guns of 12 and 24, and a mountain gun of 4.

Change in meaning of gun designations

Note that with the introduction of rifling and elongated shells replacing the old roundshot, guns could now fire projectiles weighing nearly twice the previous weight possible for a given bore (calibre). The rifling gave a far greater range for a given propellant charge, hence a minimal increase in gunpowder was needed for the heavier shells. While the La Hitte guns retained the traditional 4 designation, the number now approximated to kg rather than the livre (French pound) as previously. Hence the Canon de campagne de 4 La Hitte fired a shell weighing nearly 4 kg. Similarly, the Canon de 12 La Hitte, basically a rifled 12-cm Napoleon

, now fired a 11.5 kg shell compared to the Napoleon's 4.1 kg projectile.

Obsolescence

The La Hitte system would be superseded in 1870 with the work of Jean-Baptiste Verchère de Reffye
