a catastrophe befell French arms when General Pierre Dupont surrendered his entire corps of 18,000 men, 36 guns and all his colours to General Francisco Castaños’s Army of Andalusia after being defeated at the battle of Bailén. When the Royal Navy, which had not been party to the surrender terms, refused to repatriate Dupont’s army back to France as promised by Castaños, his troops were despatched to the Balearic isle of Cabrera, where more than half were starved to death, though Dupont and his senior officers were allowed home.
