artillery, cruisers and munitions of war for their defence.[52] A letter dated 8th April 1537, written by Gonzalo de Guzman to the Empress, furnishes us with some interesting details of the exploits of an anonymous French corsair in that year. In November 1536 this Frenchman had seized in the port of Chagre, on the Isthmus of Darien, a Spanish vessel laden with horses from San Domingo, had cast the cargo into the sea, put the crew on shore and sailed away with his prize. A month or two later he appeared off the coast of Havana and dropped anchor in a small bay a few leagues from the city. As there were then five Spanish ships lying in the harbour, the inhabitants compelled the captains to attempt the seizure of the pirate, promising to pay for the ships if they were lost. Three vessels of 200 tons each sailed out to the attack, and for several days they fired at the French corsair, which, being a patache of light draught, had run up the bay beyond their reach. Finally one morning the Frenchmen were seen pressing with both sail and oar to escape from the port. A Spanish vessel cut her cables to follow in pursuit, but encountering a heavy sea and contrary winds was abandoned by her crew, who made for shore in boats. The other two Spanish ships were deserted in similar fashion, whereupon the French, observing this new turn of affairs, re-entered the bay and easily recovered the three drifting vessels. Two of the prizes they burnt, and arming the third sailed away to cruise in the Florida straits, in the route of ships returning from the West Indies to Spain.[53]
