Maharaja Ranjit Singh gave Court employment in the artillery befitting his talents and scientific attainments. Court was responsible for the training of artillerymen, the organization of batteries and the establishment of arsenals and magazines on European lines. He was appointed director of the foundries, with the task of organizing the artillery and manufacturing cannons according to European models. The Maharaja had his own foundries for casting guns and for the manufacture of shells. Court supervised these in collaboration with Sardar
Lehna Singh Majithia. When Court produced the first shell at the Lahore foundry, the Maharaja bestowed upon him a prize of Rs 30,000, and when he produced the fuse, he was rewarded with an award of Rs 5,000. Court received a salary of Rs 2,500 per month, besides a
jagir. As early as 1822, Allard and Ventura created and commanded the
Fauj-i-khas, or special (in the sense of royal) brigade, for the ruler of the Punjab, with five infantry regiments, three cavalry regiments and a powerful artillery unit (the
Top Khana). In 1826, Court and Avitabile joined them, each creating their own brigade and, in Court's case, reshaping the entire artillery of the Punjab army. These “French” units, as they were called by both the Punjabi population (
Francisi kampu,
Francisi sarwar) and British intelligence (the French Legion), grew to 15,000 elite troops - around a third of the Sikh Empire's regular forces. These special, disciplined units were entrusted with particularly delicate or dangerous missions, ranging from the surveillance of sensitive frontiers, such as the Anglo-Sikh border or that with Baluchistan, to the military occupation of the kingdom's last major province, Peshawar, annexed by General Court, who commanded two French brigades in a particularly rapid operation in 1834. With rare exceptions, the province of Peshawar remained under “French” command from 1834 to 1843, when the French generals left Punjab to return to Europe. Court was promoted to general in 1836. General Allard, commander of all French units in the kingdom, was also the Maharaja's political advisor on foreign affairs. Claude Auguste Court continued to serve
the State after the death of Maharaja Ranjit Singh. After the death of Kanvar
Nau Nihal Singh on 5 November 1840, Court along with Ventura sided with
Sher Singh who was installed as Maharaja, with their help in investing the
Fort of Lahore, on 20 January 1841.
