Battle of Mount Tambora
The Battle of Mount Tambora, also known as the Battle of Sumbawa, the Battle of Western Sumbawa, and the Battle of Saleh Bay, was a battle fought in the island of Sumbawa during the Auro-Quenminese War, coinciding with the 1815 eruption of the aforementioned volcano. It ended with the Aurucolians taking Western Sumbawa on 6 April 1815 after the East Europan-Quenminese evacuation.
The battle progressed with relatively inconclusive results from 4 to 5 April 1815, with the Aurucolians still holding the northern side of the island, and the East Europans and Quenminese the rest. During the second day of the battle, tremors and denotations were felt and heard throughout the battlefield. Commanders from both armies were reluctant about continuing, but they would resume fighting until dusk. On the 6 April, ash began to fall and the detonations from Mount Tambora intensified. Upon the worrying signs of the volcano erupting, Gottfried Walkenhorst ordered the evacuation of all East Europan and Quenminese forces from Sumbawa. Aurucolian general Róbert Katona, despite being aware of Tambora's escalating eruption, insisted that the Aurucolians occupy the island and ignored the possibility of a violent eruption. As Tambora erupted, Sumbawa was hit with a tidal wave that virtually sunk the Aurucolian fleet stationed at the island, and the ash and pumice buried it, which left all Aurucolian soldiers and locals dead. Because of this, the battle is considered a strategic East Europan-Quenminese victory, with Aurucolian manpower decreased significantly.
