"Ships 13 skilled Halberdiers from the homeland."
In-game description

Quatrefage is a technology in Age of Empires III that is unique to the Spanish and can be researched at the Church once the Fortress Age is reached and the Royal Decree to Claim the New World Home City Card has been sent. Once researched, 13 Guard Halberdiers will appear in the Home City shipment point.

Quatrefage is the only way for the Spanish to acquire Halberdiers.

Trivia Edit

  • Unlike other similar technologies, this technology does not rename the Halberdiers.
  • The Halberdiers shipped by this technology always speak in Dutch despite of being used by the Spanish.
