On 13 April 1697, 29 ships of Pointis' fleet were seen from Bocachica. They landed troops in the coast of
Tierra Bomba island and laid sieged to the
Castle of San Luis, preventing the arrival of reinforcements. Although the Spanish knew about the incoming French attack, as spies had discovered the departure of the French fleet from the port of
Brest in January of that year. The city of Cartagena and its forts were poorly prepared when the pirates arrived. In the castle, there were only 139 men, some Spanish soldiers (most of which were slaves), with enough weapons and gunpowder, but with few foodstuffs. The food supply only arrived when the pirates surrounded the castle in two small ships. On 15 April 1697, the fort was bombarded by French warships each one with 80 cannons. The slaves rose up, asking to accept the defeat when the pirates reached the drawbridge. Don Sancho refused to surrender the castle despite the rebellion, so the French had to capture him inside the fortress while he was alone. When he was captured, he denied to surrender the castle of San Luis de Bocachica, an action that was considered admirable by Pointis. According to the popular legend, Don Sancho, as a sign to not accept defeat, broke his sword as Lord of the Castle. On honor on Jimeno's bravery, Pointis gave him his own sword. Captured by the French, Pointis granted to Don Sancho a prison in his own farm in
Isla Baru. He was held as a prisoner until the French left Cartagena in June 1697. Don Sancho was later re-designated as governor of Cartagena in 1698, after the escape of the former governor Don Diego de Los Rios, who handed over the city to the French in May 1697 without a fight. At the beginning of the 18th century, Don Sancho was judged by the Spanish tribunals, on suspect that the Spanish public servants were corrupted by French spies before the attack. However, the story of the sword of Pointis was declared as an evidence against Don Sancho. After many years through the penal process, he was declared innocent. ==Legacy==
