1902 Arbitral award of the Andes between Argentina and Chile

The Argentinian Riccheri Law continued to provide for selective national service; the expansion of the Argentine armed forces after the campaigns and subjugation of the Pampas and expanded southwards and westwards into Patagonia in the "Conquest of the Desert".

Commissioners Francisco Moreno (Argentina), Diego Barros Arana (Chile) and Sir Thomas Holdich (UK) visited the Andean Patagonian valleys to make site-based observations following the written submissions presented previously by the two parties to the Arbitration Panel.

[3] Subsequently, the commissioners visited Trevelin and received the views of the inhabitants of the "Colonia del Valle 16 de Octubre" on 30 April 1902, for three days, in School Number 18, which had been founded in 1895 next to the river Corintios by the Argentine National Government.

The arbitration award was finally adjudicated in favour of the Republic of Argentina, and Trevelin, Esquel and other adjacent settlements were subsequently incorporated into Chubut Province.

Research by Gustavo De Vera and Jorge Fiori starting in 1998 was published as the "Winds of War" in 2002 to coincide with the centenary, for the Directorate of Culture, Trevelin, has investigated the background and events around the "1902 Referendum".
