Battle of Alcácer Quibir
The infantry of the army organized for the expedition to Morocco in 1578 was made up of these four "terços" together with the "Terço" of the Adventurers (totally made up of young nobles), three mercenary "terços" (the German, the Italian, and the Castilian), and a unit of elite sharpshooters of the Portuguese garrison of Tangier. This was the Portuguese force which fought the Battle of Alcácer Quibir.
