By a Cedula of June 20th, 1671, the Viceroy of New Spain has been ordered to communicate with the Governor of Florida, hoping that through his zeal much can be accomplished in the cause of the English, preventing them from getting a strong foothold so near the mouth of the river St. Elena, which would be prejudicial to our interests. Therefore the Viceroy is requested to give all the aid required. As to the proposed fortification to this Port for its defense, do what is necessary to defend the Province and communicate also with the Viceroy whom I have commanded to try and give all the assistance possible, always bearing in mind not to violate the laws of the capitulation of peace. The Governor of Havana being nearest to Florida was also commanded to communicate with the Governor of Florida and render all the aid and assistance possible in the dislodging of the English from the river St. Elena, who if remaining in said place would cause much trouble. The Governor of Florida must also keep him informed of the state of affairs. In a letter dated April, 1671, the Viceroy Marquez de Mancera gives an account of the aid sent to the Garrison of St. Augustine in accordance with Cedula received. The papers showing that this aid had been received and approved by the Council of War, accompanying this letter, which also states the order given the Governor of New Spain to be very careful in keeping a continual correspondence with the Governor of Florida, send supplies promptly, and notify the Viceroy of all that occurs. Act in every way for the best security of that Garrison, using the greatest diligence in its fortification and defense, being as I understand of such importance. State what steps have been taken in regard to the fortification that was to be built, and to which reference is made in this dispatch to the Governor Manuel Cendovia and if the supplies of the soldiers and provisions to begin the work have arrived.
