Corunna was almost defenceless at the time of the attack. To face the English Armada's 150 ships plus boats and the soldiers in them, Corunna had one galleon ("San Juan", with 50 cannons), two galleys ("Diana" and "Princesa", with 20 cannons each), and two other smaller ships ("nao San Bartolomé" with 20 cannons, and the unarmed "urca Sansón" and "galeoncete" (small galleon) "San Bernardo"). A combination of militia, hidalgos and the few available soldiers totalled 1,500 soldiers, most of them with little military training, except for seven companies of old "tercios", who happened to be resting in the city after their return from war. It also had the mediaeval city walls, built in the 13th century.
