The battles of the Madonna of Olmo (known also as Bataille of Cuneo or Coni ) is an important victory of the Franco-Spanish armies against the Royaume of Sardinia, during the War of succession of Austria. It was held in the surroundings of Cuneo on September 30th, 1744.

It makes following an attempt of the Sardinians assist from Cuneo, besieged by the allies of the Bourbons. Charles-Emmanuel III of Sardinia gathers a consistent army, and shakes the Franco-Spanish lines. In fact, Louis François of Bourbon-Conti did not have much any more of reserves, its troops were tired of a long campaign, and its lines of too tended communications.

But French and Spanish did not move back: Charles-Emmanuel was pushed back and lost 5.000 men; the French had lost of them 1.200 and Spaniards 900. Conti was wounded twice and two horses were killed under him. But this impressive victory did not have many long-term effects. Thanks to a reinforcement of a thousand of men that, thanks to the confusion of the fray, the Sardinians had succeeded in inserting in the besieged city, as well as a whole convoy of supply, the defenders of Cuneo resisted indeed. On their side, besieging them were always prone to the epidemics and the difficulties of supply, the mountain dwellers not sparing the ambushes with the length of these lines of too wide communications; at the end of the autumn, on October 22nd, 1744, the Franco-Spanish army raised the seat, being withdrawn by the Vallée of Stura, passing by Demonte, before going to France, without to have succeeded in making the junction with the Spanish armies of the South.

Voltaire concludes: " It is almost always the fate of those which fight towards the Alps, and which do not have for them the Master of Piedmont, to lose their army, even by victories. "
