On December 12, 1803, the Souliotes left Souli towards the coast of Epirus. A monk named Samuel remained in Kughi and set fire to the powder magazines with a massive explosion that cost him his life. In the meantime, the Ottoman army attacked the other Souliotes, neglecting the promises Ali Pasha had made to them.
In a famous incident on December 16, 1803, the so-called Dance of Zalongo, 22 Souliot women were trapped by enemy troops and committed suicide to avoid capture.
According to tradition they did this by jumping off a steep cliff one after the other while dancing and singing.
This story reminds me of one of the plot threads in the Count of Monte Cristo, a personal favorite. One of the bad guys is involved in betraying Ali Pasha to the Ottomans. Maybe it was loosely based on this incident.
