Blood pointed out the fort at the mouth of the inner harbour, which was just barely visible above the waving palms on the intervening tongue of land. He announced that its armament was less formidable than that of the outer fort, which they had reduced; but on the other hand, the passage was very much narrower than the Boca Chica, and before they could attempt to make it in any case, they must dispose of those defences. He proposed that the French ships should enter the outer harbour, and proceed at once to bombardment.
Meanwhile, he would land three hundred buccaneers and some artillery on the eastern side of the lagoon, beyond the fragrant garden islands dense with richly bearing fruit-trees, and proceed simultaneously to storm the fort in the rear. Thus beset on both sides at once, and demoralized by the fate of the much stronger outer fort, he did not think the Spaniards would offer a very long resistance. Then it would be for M. de Rivarol to garrison the fort, whilst Captain Blood would sweep on with his men, and seize the Church of Nuestra Senora de la Poupa, plainly visible on its hill immediately eastward of the town. Not only did that eminence afford them a valuable and obvious strategic advantage, but it commanded the only road that led from Cartagena to the interior, and once it were held there would be no further question of the Spaniards attempting to remove the wealth of the city.
That to M. de Rivarol was - as Captain Blood had judged that it would be - the crowning argument. Supercilious until that moment, and disposed for his own pride's sake to treat the buccaneer's suggestions with cavalier criticism, M. de Rivarol's manner suddenly changed. He became alert and brisk, went so far as tolerantly to commend Captain Blood's plan, and issued orders that action might be taken upon it at once.
It is not necessary to follow that action step by step. Blunders on the part of the French marred its smooth execution, and the indifferent handling of their ships led to the sinking of two of them in the course of the afternoon by the fort's gunfire. But by evening, owing largely to the irresistible fury with which the buccaneers stormed the place from the landward side, the fort had surrendered, and before dusk Blood and his men with some ordnance hauled thither by mules dominated the city from the heights of Nuestra Senora de la Poupa.
At noon on the morrow, shorn of defences and threatened with bombardment, Cartagena sent offers of surrender to M. de Rivarol.
Swollen with pride by a victory for which he took the entire credit to himself, the Baron dictated his terms. He demanded that all public effects and office accounts be delivered up; that the merchants surrender all moneys and goods held by them for their correspondents; the inhabitants could choose whether they would remain in the city or depart; but those who went must first deliver up all their property, and those who elected to remain must surrender half, and become the subjects of France; religious houses and churches should be spared, but they must render accounts of all moneys and valuables in their possession.
Cartagena agreed, having no choice in the matter, and on the next day, which was the 5th of April, M. de Rivarol entered the city and proclaimed it now a French colony, appointing M. de Cussy its Governor. Thereafter he proceeded to the Cathedral, where very properly a Te Deum was sung in honour of the conquest. This by way of grace, whereafter M. de Rivarol proceeded to devour the city.
The only detail in which the French conquest of Cartagena differed from an ordinary buccaneering raid was that under the severest penalties no soldier was to enter the house of any inhabitant.
But this apparent respect for the persons and property of the conquered was based in reality upon M. de Rivarol's anxiety lest a doubloon should be abstracted from all the wealth that was pouring into the treasury opened by the Baron in the name of the King of France. Once the golden stream had ceased, he removed all restrictions and left the city in prey to his men, who proceeded further to pillage it of that part of their property which the inhabitants who became French subjects had been assured should remain inviolate. The plunder was enormous. In the course of four days over a hundred mules laden with gold went out of the city and down to the boats waiting at the beach to convey the treasure aboard the ships.
