The siege of Ragusa took place in 1806 during the Napoleonic Wars (the War of the Third Coalition in a certain period).
After French occupied the maritime republic of Ragusa, Russian and allied forces under the leadership of Vice Admiral Dmitry Senyavin laid siege to it for months. The Russian allies included Montenegrins, commanded by the Orthodox bishop of Montenegro, Petar I PetroviÃÂ-Njegoà ¡. Divisional general Auguste de Marmont was the "ruler" and supreme commander in the republic. The siege saw several stormings/engagements at local strongholds with varying results, but it all eventually resulted in the Russian alliance abandoning the siege attempt when French General G. Molitor appeared in the rear and thus saved the republic. Molitor, under the command of Jean-de-Dieu Soult, once managed to hold back the onslaught of Generalissimo Alexander Suvorov-Rymniksky at Näfels during the battle of Glarus; now he received the glory of being the victor over Admiral Dmitry Senyavin.
During the siege, Senyavin and French General Jacques Lauriston, who commanded in the city of Ragusa (now Dubrovnik), conducted extensive correspondence and even met in person.
