The Austrians had captured and then lost Genoa the previous year and made it the central objective of their strategy for 1747 before they would consider further operations against Naples or an invasion of France. Schulenburg's force reached the outskirts of the city in April, but realising they needed more troops they waited until twelve battalions of infantry from their Sardinian allies arrived in June. The delay allowed the French and Spanish to send reinforcements to the city under Joseph Marie, Duke of Boufflers [Wikidata] to bolster the garrison.

The approach of a Franco-Spanish force under Marshal Belle-Isle and General Las Minas pressured the Sardinians to withdraw to try to defend a possible threat to Milan, and Schulenberg then abandoned the siege blaming the Sardinians. The failed siege led to recriminations between Vienna and Turin with both complaining to their British allies in London about the alleged betrayal of the other.^[1]
