Tinos and sold her jewelry to finance the equipment of 200 men who fought the enemy and cherish two thousand people who had survived from the first siege of Missolonghi. Her men participated in several other battles like those of Pelion, Phthiotis and Livadeia. Mavrogenous led enlightenment expeditions in Europe and addressed an appeal to the women of Paris, to side up with the Greeks. She moved to Nafplio in 1823, in order to be in the core of the struggle, leaving her family as she was despised even by her mother because of her choices. It is at this time that Mavrogenous met Demetrios Ypsilantis, with whom she was soon engaged. Soon, she became famous around Europe for her beauty and bravery. But in May of the same year, her home was totally burnt and her fortune was stolen, and as a result she went to Tripoli to live with Ypsilanti, while Papaflessas provided her with food. Mavrogenous' engagement to Demetrios Ypsilantis was opposed by several powerful politicians who saw the unification of two powerful families, Mavrogenis and Ypsilantis, which held pro-Russian affiliations as a threat. Chief among their opponents in Greece was Ioannis Kolettis who lead the successful charge to break the engagement. After the engagement she returned to Nafplio, where she lived, deeply depressed, in destitution and was not repaid the money she had given for various battles. After Ypsilanti's death and her intense political conflicts with Ioannis Kolettis, she was exiled from Nafplio and returned to Mykonos, where she occupied with the writing of her memoirs. When the war ended Ioannis Kapodistrias awarded her the rank of the Lieutenant General and granted her a dwelling in Nafplio, where she moved. She owned a treasurable sword, with the inscription "Δίκασον Κύριε τους αδικούντας με, τους πολεμούντας με, βασίλευε των Βασιλευόντων", which is translated to 'Lord, judge those who wrong me, who battle me, rule over the Kings'. That sword is said to come from the times of Constantine the Great and Mavrogenous gave it to Kapodistrias. Later years Mavrogenous moved to Paros in 1840, where some of her relatives resided, and lived and died in a house that is still privately owned. The home is located near the Panagia Ekatontapyliani (the Church of the Virgin Mary) which, tradition says, was founded by Saint Helena, mother of Constantine the Great. Mavrogenous died on Paros in July 1848, alone
