The siege of Kastania was fought in July 1780 between the Maniots and the klephts under Konstantinos Kolokotronis and Panagiotaros Venetsakis and the Ottoman Empire under Ali Bey.

Even though the Maniots were bottled by the fierce Turko-Albanian soldiers who ravaged the Peloponnese they still managed to cause damage to the Ottomans with their pirate ships and with raids into Laconia.

[1] The Maniots had heard that Ali Bey and Panagiotaros sent a man to his father-in-law Tzanetos Grigorakis to bring a relief force.

[1] But Tzanetos was busy preparing the rest of the Maniot army with his uncle Exarchos Grigorakis near their home town of Skoutari.

[1] Ali Bey sent a man to the defenders offering to call off the siege if Kolokotronis and Panagiotaros each gave him one of their children.

They came to the conclusion that on the twelfth night at midnight when the moon didn't shine they would sneak out and make for the forests around the town with a group of men covering the rear and the vanguard while the women and the children were in the middle.

His wife with his young son Theodoros Kolokotronis, the future hero of the Greek War of Independence, escaped.

The victorious Ottomans then were routed by the combined Maniot forces under the command of Tzanetos and Exarchos Grigorakis.
