Siege of Acre

Siege of Acre, a siege battle that took place in May 1799 between the Ottoman State and France, resulting in a decisive Ottoman victory. This victory halted the advance of French general Napoleon Bonaparte in the Eastern Mediterranean and secured the continuation of Ottoman dominance in the Levant region. One of the principal figures in the victory, Cezzar Ahmed Pasha, gained recognition for his successful defensive strategy and secured an important place in Ottoman military history.

In the late 18th century, the political and military upheavals following the French Revolution in Europe also affected the Mediterranean and the Middle East. Napoleon Bonaparte invaded Egypt in 1798 to sever Britain’s trade routes to its colony India and weaken its power, thereby threatening Ottoman supremacy in the region and drawing British attention. In response, the Ottoman State began to draw closer to Britain and adopted military and diplomatic measures against France.

Cezzar Ahmed Pasha, responsible for the defense of Acre, was a prominent figure in the late 18th-century Ottoman administrative and military structure. Believed to have been born in Bosnia between 1720 and 1730, Ahmed Pasha moved to Istanbul at a young age, received madrasa education, and held various posts in Egypt and Syria. Described as stern, authoritarian, yet resolute, Cezzar Ahmed Pasha was appointed governor of Syria in 1775 and established a powerful administrative-military center based in Acre.

Cezzar Ahmed Pasha anticipated the French threat and repaired Acre’s fortifications, strengthened its armories, and organized the local population for defense. He also maintained communication with the Ottoman central administration (Divân-ı hümâyûn) to request reinforcements and supplies. During this period, he coordinated with Britain and benefited from British support, particularly in naval defense.

On 19 March 1799, Napoleon Bonaparte arrived before Acre and laid siege to the fortress. He was accompanied by experienced generals (Kléber, Lannes, Junot) and a force of approximately 13,000 men. During the siege, the French employed modern siege equipment and artillery to breach Acre’s walls, but they failed due to the strength of the fortifications and the determined resistance of the defenders.

Meanwhile, the British fleet under Admiral Sir Sidney Smith destroyed much of the French naval force anchored off Acre, cutting off French supply lines from the sea. Additionally, the British captured French ships transporting artillery intended for the siege from Egypt and handed them over to Cezzar Ahmed Pasha, significantly enhancing the defenders’ capabilities.

Cezzar Ahmed Pasha’s defensive strategy was built on a participatory structure that united the city’s population along with various ethnic and sectarian groups. According to Ottoman sources, the defense included local militias, military units of Albanian and Kurdish origin, reinforcements from Egypt, and Arab tribes.

Throughout the siege, Napoleon attempted to capture the fortress thirteen times but failed each time. The French employed intense artillery bombardments, tunneling, and night raids. However, every assault was repelled by Cezzar Ahmed Pasha’s defense and British naval gunfire. Cezzar Ahmed Pasha personally fought alongside his troops on the walls, carefully maintaining the morale of the population.

On 10 May 1799, Napoleon was forced to withdraw after realizing the siege could not succeed. This retreat marked the failure of Napoleon’s military plans in the Eastern Mediterranean; he later described the outcome as “Fate made me the pawn of an old man.”

The Siege of Acre is recorded as one of the most significant and rare military victories achieved by the Ottoman State in the late 18th century. With this victory, French advances were halted, the alliance between Britain and the Ottoman State was strengthened, and Cezzar Ahmed Pasha’s reputation was greatly enhanced.

In Ottoman archival documents, the Siege of Acre is recorded as “a significant achievement of Cezzar Ahmed Pasha” and was praised by the central administration. The documents detail Napoleon’s persistent attacks during the siege, the success of the defense, and the resilience shown by the population. Furthermore, the victory letter sent by Cezzar Ahmed Pasha to Istanbul and the imperial commendations issued by the sultan in response illustrate the victory’s resonance within the central Ottoman bureaucracy.
