While the mareschal de Belleisle remained at Ventimiglia, his brother, at the head of four-and-thirty thousand French and Spaniards, attempted to penetrate into Piedmont: on the sixth day of July he arrived at the pass of Exilles, a strong fortress on the frontiers of Dauphiné, situated on the north side of the river Doria. The defence of this important post the king of Sardinia had committed to the care of the count de Brigueras, who formed an encampment behind the lines, with fourteen battalions of Piedmontese and Austrians, while divers detachments were posted along all the passes of the Alps. On the eighth day of the month the Piedmontese intrenchments were attacked by the chevalier de Belleisle, with incredible intrepidity; but the columns were repulsed with great loss in three successive attacks. Impatient of this obstinate opposition, and determined not to survive a miscarriage, this impetuous general seized a pair of colours, and advancing at the head of his troops through a prodigious fire, pitched them with his own hand on the enemy’s entrenchments. At that instant he fell dead, having received two musquet-balls and the thrust of a bayonet in his body. The assailants were so much dispirited by the death of their commander, that they forthwith gave way, and retreated with precipitation towards Sesteries, having lost near five thousand men in the attack. The mareschal was no sooner informed of his brother’s misfortune, than he retreated towards the Var to join the troops from Exilles, while the king of Sardinia, having assembled an army of seventy thousand men, threatened Dauphiné with an invasion; but the excessive rains prevented the execution of his design. General Leutrum was detached with twenty battalions, to drive the French from Ventimiglia; but Belleisle marching back, that scheme was likewise frustrated; and thus ended the campaign.
