How a midnight raid on a sleeping city turned into an unexpected stalemate
In the winter of 1702, Prince Eugene of Savoy attempted a daring surprise attack on the French-held city of Cremona. By infiltrating the walls through a hidden sewer, his forces nearly secured a total victory, only to be thwarted by the stubborn resistance of two elite Irish infantry units.
The conflict unfolded during the War of the Spanish Succession, a period when the Duchies of Milan and Mantua served as critical gateways to Southern Austria. By early 1701, French forces had occupied these territories, prompting Emperor Leopold to dispatch Prince Eugene of Savoy to reclaim them. Eugene, a brilliant strategist, had already secured victories at Carpi and Chieri. Facing severe supply shortages from Vienna, he chose to break with military convention by launching a winter offensive, hoping to catch his opponents off guard.
On the night of 31 January 1702, Eugene executed a sophisticated plan. Assisted by a local priest named Cuzzoli, a group of Imperial grenadiers entered Cremona through an obscure culvert and opened the St Margaret Gate. Approximately 4,000 troops surged into the city, catching the French garrison in their beds. In the ensuing chaos, the French commander, Maréchal Villeroi, was captured in his own quarters. However, the operation faltered when a secondary force tasked with seizing the Po gate and the Citadel arrived behind schedule.
This delay allowed the French to destroy a key bridge and organize a defense. Two units of the Irish Brigade—the Dillon and Bourke regiments—held their ground against the Imperial assault, suffering heavy losses of about 350 men out of 600. Their resilience provided the time needed for French reinforcements to arrive. By daylight, Eugene recognized the tactical shift and ordered a withdrawal. The engagement left the Austrians with roughly 1,600 casualties and the French with 1,100. While the French retained the city, the capture of their commander became a source of public mockery, immortalized in verse and song.
The aftermath saw the rise of Major Daniel O'Mahoney, the Irish commander who led the defense. His performance earned him a knighthood from the exiled James III and an audience with Louis XIV. O'Mahoney continued a storied military career across Spain and Sicily, eventually reaching the rank of Lieutenant-General before his death in 1714. The battle itself left a lasting legacy, with the Irish Brigade adopting a march named after the event to commemorate their role in the defense.
