In 1580 he returned from another voyage in the West Indies, just when a body of so-called papal volunteers had landed in Ireland. They had been brought by a Spanish officer in Spanish ships, and the queen, pending a satisfactory explanation, refused to receive Mendoza, the Spanish ambassador, and hear his complaints of Drake's piracies. When his ships had been brought round in the Thames, she visited him on board and conferred on him the honor of knighthood. From this time onward he became a servant of the crown.[38]

It was this redoubtable sea-rover who, according to advices received early in 1595, was preparing an expedition in England for the purpose of wresting her West Indian possessions from Spain. The expedition was brought to naught, through the disagreements between Drake and Hawkyns, who both commanded it, by administrative blunders and vexatious delays in England. The Spaniards were everywhere forewarned and goaded to action by the terror of Drake's name.

Notwithstanding this, the island's fate, seeing its defenseless condition, would, no doubt, have been sealed at that time but for a most fortunate occurrence which brought to its shores the forces that enabled it to repulse the attack. Acosta's annotations on Abbad's history contains the following details of the events in San Juan at the time:

"General Sancho Pardo y Osorio sailed from Havana March 10, 1595, in the flagship of the Spanish West Indian fleet, to convoy some merchantmen and convey 2,000,000 pesos in gold and silver, the greater part the property of his Majesty the king. The flagship carried 300 men.

"On the 15th, when in the Bermuda channel, a storm separated the convoy from the other ships, sent her mainmast overboard, broke her rudder, and the ship sprang a leak. In this condition, after a consultation among the officers, it was decided to repair the damage as well as possible and steer for Puerto Rico, which they reached on the 9th of April. The treasure was placed in security in the fort and messengers despatched to the king to learn his Majesty's commands.

"A few days later official advice of the preparations in England was brought to the island in a despatch-boat. Governor Juarez, General Sancho, and the commander of the local infantry held a council, in which it was resolved to land the artillery from the dismasted ship and sink her and another vessel in the channel at the entrance to the harbor, while defenses should be constructed at every point where an enemy could attempt a landing. The plan was carried out under the direction of General Sancho, who had ample time, as no enemy appeared during the next seven months.

"On the 13th of November 5 Spanish frigates arrived under the command of Pedro Tello de Gúzman, with orders from the king to embark the treasure forthwith and take it to Spain; but Tello, on his way hither, had fallen in off Guadeloupe with two English small craft, had had a fight with one of them, sank it, and while pursuing the other had come suddenly in sight of the whole fleet, which made him turn about and make his way to Puerto Rico before the English should cut him off. From the prisoners taken from the sunken vessel he had learned that the English fleet consisted of 6 line-of-battle ships of 600 to 800 tons each, and about 20 others of different sizes, with launches for landing troops, 3,000 infantry, 1,500 mariners, all well armed and provided with artillery, bound direct for Puerto Rico under the command of Sir Francis Drake and John Hawkyns.

"Tello's 5 frigates made a very important addition to the island's defenses. Part of his men were distributed among the land forces, and his ships anchored in the bay, just behind the two sunken ships.

"All was now ready for a determined resistance. General Sancho had charge of the shore defenses, Admiral Gonzalo Mendez de Cauzo commanded the forts, Tello, with his frigates and 300 men, defended the harbor. The bishop promised to say a mass and preach a sermon every day, and placed a priest at every post to give spiritual aid where necessary. Lastly, despatch-boats were sent to la Española and to Cuba to inform the authorities there of the coming danger.

"The defensive forces consisted of 450 men distributed at different points on shore with 34 pieces of ordnance of small caliber. In the forts there were 36 pieces, mostly bronze ordnance, with the respective contingent of men. On board of Tello's frigates there were 300 men.
