Pierros Grigorakis, a son of Zanetos, entered Russian service on Zante and commanded a force of some 500 Maniots known as the Spartan Legion. This was part of the Legion of Light Riflemen, a force made up of mainland refugees that defended the Ionian Islands and participated in Russian operations in the Mediterranean in the years 1805–1807. Many veterans of this unit later joined the secret society Filiki Eteria ("Friendly Company") and participated with the Greek Revolution, including Elias Chrisospathis, who initiated the Maniots into the secret society, as well as Pierros and his brothers Giorgos and Zanetakos.
