Johann Jakob Meyer in the context of Siege of Messolonghi (1825)

The third siege of Missolonghi (Greek: Τρίτη Πολιορκία του Μεσολογγίου, often erroneously referred to as the second siege) was fought in the Greek War of Independence, between the Ottoman Empire and the Greek rebels, from 15 April 1825 to 10 April 1826. The Ottomans had already tried and failed to capture the city in 1822 and 1823, but returned in 1825 with a stronger force of infantry and a stronger navy supporting the infantry. The Greeks held out for almost a year before they ran out of food and attempted a mass breakout, which however resulted in a disaster, with the larger part of the Greeks slain. This defeat was a key factor leading to intervention by the Great Powers who, hearing about the atrocities, felt sympathetic to the Greek cause. Their support would prove decisive in helping the Greeks win the war and gain independence.
