Castle of the Three Kings of Morro

This guide to the Castle of the Three Kings of Morro in Havana follows the 1762 British siege, when attacking forces found almost no fresh water on the ridge where they dug their batteries and had to haul every barrel up from the coast under tropical heat. It traces how thirst and fever spread through both camps, the grim casualty counts on the British side, and the roughly seven hundred Spanish defenders under Luis de Velasco who held the walls. Look for the garrison's own latrines, still cut into the rock below, their chutes open to the same sea that nearly defeated the besiegers.
