After the action, one of the English privateers quarrelled with one of his French shipmates and stabbed him in the back, killing him. Before a riot between the French and English sailors could begin, Morgan arrested the English sailor, and promised the French sailors that the man would be hanged on his return to Port Royal. Morgan kept his word and the sailor was hanged. After dividing the spoils of the conquest of Puerto Principe, Morgan announced a plan to attack Porto Bello (now in modern-day Panama). The city was the third largest and strongest on the Spanish Main, and on one of the main routes of trade between the Spanish territories and Spain. Because of the value of the goods passing through its port, Porto Bello was protected by two castles in the harbour and another in the town. The 200 French privateers, unhappy with the division of the treasure and the murder of their countryman, left Morgan's service and returned to Tortuga. Morgan and his ships briefly landed at Port Royal before leaving for Porto Bello.
