The Battle of Luzzara took place in Lombardy on 15 August 1702 during the War of the Spanish Succession, between a combined French and Savoyard army under Louis Joseph, duc de Vendôme, and an Imperial force under Prince Eugene.
Conflict in Northern Italy centred around the Spanish-held Duchies of Milan and Mantua, which controlled access to the southern borders of both France and Austria. When the war began in 1701, Savoy allied with France; despite being out numbered, by February 1702 the Imperialists held the strategic initiative.
Vendôme took the offensive, taking Modena and Reggio in July, followed by Luzzara in August, a vital crossing point over the River Po. Threatened with being cut off from his supply base at Mirandola, Prince Eugene launched a series of attacks on the French positions at Luzzara.
Fighting continued until midnight, when the Imperialists ended their attack, having failed to break through; they suffered 2,000 casualties, the French lost around 4,000. While this ended Vendôme's offensive for the year, the French-Savoyard army had recovered nearly all the ground lost in 1701.
Background
The War of the Spanish Succession was triggered by the death in November 1700 of the childless Charles II of Spain. He named his heir as Philip of Anjou, grandson of Louis XIV of France, and on 16 November 1700, he became king of the Spanish Empire. In addition to mainland Spain, this included the Spanish Netherlands, large parts of Italy, and much of Central and South America. In 1701, disputes over territorial and commercial rights led to war between France, Spain, and the Grand Alliance, whose candidate was Charles, younger son of Leopold I, Holy Roman Emperor.
The war in Northern Italy centred on the Spanish-held Duchies of Milan and Mantua, which were considered essential to the security of Austria's southern borders. In March 1701, French troops occupied both cities; Victor Amadeus II, Duke of Savoy, allied with France, in return for which his daughter Maria Luisa married Philip V.
Over the next 12 months, Imperial general Prince Eugene of Savoy won a series of victories over French commander Villeroi, forcing him to withdraw behind the Adda river. He was unable to fully exploit this success as Leopold diverted resources from Italy to deal with problems elsewhere. Instead, he improvised, and in a surprise winter campaign, captured Villeroi at Cremona in February 1702, before laying siege to Modena. Determined to retain control of this region, Louis sent Vendôme to replace Villeroi, along with substantial reinforcements.
On 12 July, Vendôme was joined by Philip V, who had been visiting Spanish possessions in Italy, including Naples, Sicily, and Milan. This brought their combined army up to 30,000 – 35,000, including 10,000 Savoyards and five regiments of the Irish Brigade. In July, Vendôme captured Modena, then turned north to take Guastalla; on 26 July, he clashed with Imperial cavalry under Visconti at Santa Vittoria.
In early August, a detachment under Vendôme besieged Luzzara, a small town held by an Austrian garrison of 500, that controlled a bridge over the Po River. Prince Eugene now faced being cut off from his supply base at Mirandola; he abandoned his blockade of Mantua, and marched on Luzzara, telling its governor to hold on until he arrived. Many of his troops were tied up in garrisons at Mirandola, Bersello and Borgoforte, leaving him with a field army of 26,000. On 14 August, he reached Riva, a village north of Luzzara; here he learned the town had already surrendered, and the rest of Vendôme's army was moving into a camp just outside.
Battle
Between Luzzara and the Po River, there were two earth embankments, built to prevent the river flooding the countryside; a high one just outside the town, and a smaller one close to the river (see Map). Prince Eugene planned to conceal his troops behind these, and take the French-Savoyard army by surprise; since their first task would be to collect forage, and water the horses, he hoped to take them unarmed. He split his forces into two lines, the left under Visconti and the Prince de Commerci, the right under Vaudémont, while he commanded the centre.
