There they refreshed themselves, and advancing upon the town surprised the enemy, who knew of the late landing and the badness of the way and did not expect them so soon. They found 200 Spaniards at the entrance to the town, drawn up under their governor, Don Pedro de Moralis, and supported by Don Christopher de Sasi Arnoldo, the former Spanish governor of Jamaica, with a reserve of 500 more. The Spaniards fled before the first charge of the Jamaicans, and the place was easily mastered. The next day parties were despatched into the country to pursue the enemy, and orders sent to the fleet to attack the forts at the mouth of the harbour. This was successfully done, the Spaniards deserting the great castle after firing but two muskets. Between scouring the country for hidden riches, most of which had been carried far inland beyond their reach, and dismantling and demolishing the forts, the English forces occupied their time until October 19th. Thirty-four guns were found in the fortifications and 1000 barrels of powder. Some of the guns were carried to the ships and the rest flung over the precipice into the sea; while the powder was used to blow up the castle and the neighbouring country houses.[167] The expedition returned to Jamaica on 22nd October.[168] Only six men had been killed by the Spaniards, twenty more being lost by other "accidents." Of these twenty some must have been captured by the enemy, for when Sir Richard Fanshaw was appointed ambassador to Spain in January 1664, he was instructed among other things to negotiate for an exchange of prisoners taken in the Indies. In July we find him treating for the release of Captain Myngs' men from the prisons of Seville and Cadiz,[169] and on 7th November an order to this effect was obtained from the King of Spain.[170] The instructions of Lord Windsor gave him leave, as soon as he had settled the government in Jamaica, to appoint a deputy and return to England to confer with the King on colonial affairs. Windsor sailed for England on 28th October, and on the same day Sir Charles Lyttleton's commission as deputy-governor was read in the Jamaican Council.[171] During his short sojourn of three months the Governor had made considerable progress toward establishing an ordered constitution in the island. He disbanded the old army, and reorganised the military under a stricter discipline and better officers. He systematised legal procedure and the rules for the conveyance of property. He erected an Admiralty Court at Port Royal, and above all, probably in pursuance of the recommendation of Colonel Doyley,[172] had called in all the privateering commissions issued by previous governors, and tried to submit the captains to orderly rules by giving them new commissions, with instructions to bring their Spanish prizes to Jamaica for judicature.[173]
