On 31August the French troops were forced to retreat from the town to their stronghold on the hill and fortress Urgull. When it seemed that damage to the town and its dwellers was limited, many of the allied rank-and-file as evidenced by local witnesses went on a rampage spree, taking to killing (estimated 1,000 civilians), looting, raping the women and burning almost the whole town to the ground, a mayhem lasting for a week. On 9 September the Governor Rey surrendered the citadel, and the garrison, reduced to one-third of their number, marched out with the honours of war. The reduction of this important place cost the British three thousand eight hundred men in killed and wounded. A candle-lit memorial event is held nowadays every 31 August, mourning these tragic days.
