Dommartin received his first commission in 1785, serving as a captain of the artillery.

Therefore, an ambitious young artillery captain named Napoleon Bonaparte assumed command of the French artillery, with notable success.

Bonaparte then chose him in 1798 to command the artillery for the invasion of Egypt as acting general of division.

His name is engraved on the south side of the Arc de Triomphe.
