Awake iron!

(Catalan: Desperta Ferro!, IPA: [dəsˈpɛɾtə ˈfɛru]; Medieval Aragonese: Desperta Ferres!)

was a battle cry of the Middle Ages employed by the Almogavars.

It was shouted on entering the fight, to frighten the enemy and invoke the presence of iron in the battle.

The cry was given as the Almogàvers struck their lances and darts with flints, causing sparks to fly up from the stones.

Nowadays, it is still used as a motto for the Spanish Army 6th Paratroopers Brigade "Almogávares".
