Background and detail

Strategic Context. Following the French defeat at the Battle of the Sesia in April 1524, Habsburg forces pursued the retreating French army across the Alps. Led by Charles de Bourbon, who had defected to Charles V, these troops sacked smaller Provençal towns and entered Aix-en-Provence on 9 August before turning their attention to Marseille.

Siege Operations. Imperial troops arrived in Marseille on 15 August, with the formal siege beginning on 19 August. The first assault occurred on 23 August. For the following month, the city defended itself by plugging rampart breaches, cutting off Imperial tunnels with trenches, and repelling multiple offensives, including a final attempt on 24 September.

Imperial Withdrawal. The siege ended in failure for the besiegers. After the failed assault on 24 September, Imperial forces withdrew toward Italy on 29 September. This retreat was necessitated by the threat of a French relief army approaching from Avignon, commanded in person by King Francis I.
