After the seize of Souli, Ali Pasha decided to destroy the Souliotes who had been forced by a treaty to leave their villages and withdraw to Zalongos. The surprise attack by the army of the Pasha led to a ferocious battle with many casualties on both sides. By taking a heroic decision, the women of Souli (Souliotisses) and their children, during a ceremonial dance, one by one, fell off the cliff choosing not to be captured alive by the Pasha. Their act caused great emotion in Greece and Europe.
