The Frenchman then threatened to burn the town, which Guzman wished he would do, in order to bring the King's government to its senses and arouse it to the necessity of defending Cuba. But there chanced to be in the port a certain merchant of Seville, by name Diego Perez, who was at least as daring as the Frenchman himself. He had a little merchant sloop, not more than half the size of the Frenchman, but well armed, with guns that would carry at least as far as the Frenchman's. He ran his little craft into water too shallow for the bigger Frenchman, where he would be secure against ramming or boarding, and there began peppering the enemy with his long range guns, Perez himself aiming the best of them. The fight lasted all day, and Perez was ready to resume it next morning. But in the darkness of the night the Frenchman stole away and was seen no more in Santiago harbor. Perez had three men killed, and his vessel was badly damaged; but the Frenchman probably suffered heavier losses, since two of his men who were killed fell overboard and were picked up and buried by the Spaniards, and there were almost certainly others killed. For his valor on thus saving the capital of Cuba from destruction, Perez received from the King a coat of arms with a device emblematic of his achievement. That same Frenchman a little later, having repaired his vessel, wreaked his revenge upon Havana. When he entered the harbor there the people fled and left the town for him to loot at his leisure. It is recorded that he took even the church bells. Moreover, being a truculent Huguenot, he took an image of Saint Peter from the church and let his men use it as a target to pelt with oranges! This incident caused De Soto, who arrived at Havana a little later, to hasten work on the defences of the place. For some time there had been talk of building a fort, but no agreement had been reached as to where it should be; whether at the Cabana, or the Morro, or on the hill in what is now Central Park. But the Frenchman's raid brought the controversy to an end, and De Soto was authorized to build wherever he thought best. The result was the building of La Fuerza. It was hastily built, and therefore badly, so that ten years later part of it had to be torn down and the whole remodelled into its present form.
