The stratagem succeeded.

On the twenty-sixth the Turkish army was in motion.
A detachment of the Imperialists attacked them in flank as they marched through a wood.

A very desperate action ensued, in which the generals Heusler and Poland, with many other gallant officers, lost their lives.
At length the Ottoman horse were routed; but the Germans were so roughly handled, that on the second day after the engagement they retreated at midnight, and the Turks remained quiet in their intrenchments.
In Piedmont the face of affairs underwent a strange alteration.

The duke of Savoy, who had for some time been engaged in a secret negotiation with France, at length embraced the offers of that crown, and privately signed a separate treaty of peace at Loretto, to which place he repaired on a pretended pilgrimage.

The French king engaged to present him with four millions of livres by way of reparation for the damage he had sustained, to assist him with a certain number of auxiliaries against all his enemies, and to effect a marriage between the duke of Burgundy and the princess of Piedmont, as soon as the parties should be marriageable.
The treaty was guaranteed by the pope and the Venetians, who were extremely desirous of seeing the Germans driven out of Italy.
King William being apprized of this negotiation, communicated the intelligence to the earl of Galway, his ambassador at Turin, who expostulated with the duke upon this defection; but he persisted in denying any such correspondence, until the advance of the French army enabled him to avow it without fearing the resentment of the allies whom he had abandoned.
