Eugene had a contact inside Cremona, a priest named Cuzzoli; on the night of 31 January 1702, he admitted a party of Imperial grenadiers by means of a hidden culvert and they seized control of the St Margaret Gate. Once open, approximately 4,000 troops led by Prince Eugene in person took the French by surprise, many being killed as they emerged from their barracks, and Maréchal
Villeroi captured in his quarters. A second and larger force under
Prince de Vaudémont was intended to storm the
Po gate and the Citadel but was late in arriving. This gave the garrison time to destroy a vital bridge and prepare, the assault being repulsed by two units of the
Irish Brigade, the Régiment de Dillon and the Régiment de Bourke. The defenders now regrouped and counter-attacked; with daylight and a French relief force arriving, Prince Eugene ordered his troops to withdraw, the Austrians having suffered an estimated 1,600 casualties, the French around 1,100. ==Aftermath==
