Digonet participated in the 1806 invasion of Naples. At the Battle of Maida on 4 July 1806, Digonet led a brigade in Jean Reynier's division. His command included two battalions of the 1,266-strong 23rd Light Infantry Regiment, 328 sabers of the 9th Chasseurs à Cheval Regiment and several artillery pieces manned by 112 gunners. Reynier's division attacked the British with brigades under Louis Fursy Henri Compère and Luigi Gaspare Peyri echeloned forward by the left. Compère's charge was met by devastating British musketry and dispersed with heavy losses. Many of Peyri's troops became involved in the rout though a Swiss battalion kept its order and rallied on Digonet's brigade. Enemy brigades under Lowry Cole, Wroth Palmer Acland and John Oswald converged on Digonet's troops but were stopped when the 9th Chasseurs made a series of partial charges, forcing the British to deploy into squares. Finally, a newly arrived British regiment broke the stalemate by attacking from a new direction and Digonet conducted a retreat.
