De Lannoy, (Guillaume) Augustin (also written as Delannoy, Delannoi, Delanoi) was a volunteer from Brussels, Belgium. According to some sources (i.e. Fornezy) a certain “Delannoi” was reported to be part of the Battalion of the Philhellenes commanded by General Norman. Same sources argue that he fought in Peta in July 1822.
However, according to Belgian newspapers (e.g. Le Courrier de la Meuse of 5 June 1826), Augustin De Lannoy and N.J. Trumper left Belgium in 1824 for Greece.
De Lannoy participated in many fundraising concerts and commemoration services, to support the Greek cause, and his name appeared often in the European press.
As of his arrival in Greece in 1824, he joined the Regular Army under General Fabvier and he was appointed Captain of the Light Infantry of the Third Greek battalion. In 1826 he moved with the army units which stationed in Troizina, with a mission to stop the forces of “Ibrahim-Pacha”. In this context, he participated in many operations until June 1826 and very likely also in the battle of Myloi, where 500 Greek fighters and Philhellenes defeated an army of 6600 Ottomans led by Ibrahim-Pascha himself.
A little later he died on the island of Andros of 6 July 1826.
His contribution was recognized and his name figures on the monument of Toure in the church of The Transfiguration of the Saviour in Nafplio.
SHP and the people of Greece pay tribute to this great Belgian Philhellene, and honor his memory, together with the one of all his Belgian comrades who offered their services, and even their lives, to the Greek war of independence, as volunteers in Greece or through their participation in the philhellenic movement in Belgium.
