Fourth: This person should have an understanding with the commander of the Castilian expedition both as to the time of the attack, and whether they should meet later during the conquest, and for whatever other question might arise between them during the progress of the affair, which should need settlement. This should be very clear, leaving no room for dissensions.
Fifth: If the Japanese who are to be taken on the expedition do not wish to join the Castilians, and prefer to go in with the Portuguese, since they already know them, and likewise because they get along better, and the Portuguese treat them more as equals than is permitted here [they may do so]. But if they wish to go with the Castilians, let them come to Cagayan, and this will be arranged with them and with the fathers of the Society of Jesus, who are to act as guides. [45]
Sixth: His Majesty should procure and bring about that the general of the Society of Jesus should command and ordain to the fathers in Japon, not to hinder the bringing of this reenforcement of Japanese, and whatever may be needed therefor; and to this end he should send a father sufficiently commissioned, who should be an Italian.
Seventh: At the proper time and juncture, which will be before the news of the expedition has come to the knowledge of the Chinese, the fathers of the Society who are within the borders of China, in the city of Joaquin, should be withdrawn, that they may give information to the armies about what they know of the country, its strength, and its military forces and supplies; and whatever other dangers or reasons for caution they have in mind. They will also serve as interpreters, and persuade the Chinese to allow the Spaniards to enter in peace, and to hear and receive the preachers, and accept the religion sent them by God. They will tell the Chinese of the protection which his Majesty desires to offer them, so that they may receive the Spaniards without fear; and how great a favor he is doing them in freeing them from the tyrannies of their mandarins, and relieving them from the yoke of slavery that they at present bear, leaving them in freedom of body and soul, and exacting nothing but an acknowledgment for this gracious act. To this end the fathers should write many chapas, and scatter them over the whole of China, and be of use in any other way that their years of life in the country may make possible. These should be the instructions of the general of the Society of Jesus to his commissioner.
Eighth: Let it be known in España that as the voyages of the Portuguese to the east and the Castilians to the west should and must be made and end at the same time, the movement of the winds is favorable to them; for the Portuguese can come to Macan at the end of May, and during the whole of June, when the first junks usually come from Maca, and the Castilians will arrive at Cagayan at the same time.
Ninth: Those arriving first should send a dispatch-boat to the Point, to meet the other fleet. This can be done by two or three routes, for at that season very small and light boats can be navigated; and the distance is not great, about one hundred and fifty leagues on each side.
Of dangers, and risks of great misfortunes to be known and guarded against by his Majesty on this expedition
First: If the number of troops in both armies were small even though well armed and equipped, since the Chinese are so numerous, they will be deluded and offer resistance; and as the Spaniards are brave fighters, the havoc and slaughter will be infinite, to the great damage of the country. Therefore an effort should be made to have the troops so numerous, well equipped, trained, and strategically handled, that there will be no chance for resistance; and their mere presence and a demonstration will suffice to cause the Chinese to submit, with no great bloodshed. In this way there will be no danger that the Spaniards, finding themselves surrounded and pressed by such a multitude, incited and urged on by the mandarins, should cause appalling havoc and cut them down, thus harming agriculture and lessening the population of the country.
Second: Do not let them come so few in numbers, or ill armed and supplied, undisciplined or insubordinate, as to cause any danger of confusion, discouragement, or desertion, in parts so remote as these, as this would be the ruin of the expedition; or they would go about it in such a way as to preclude success, and leave the Chinese our declared enemies, meanwhile losing our reputation and the bright hopes we now have of getting the port of Macan and a passage to Japon. There would then be no hope of the christianization which depends on intercourse with them, and we should lose the riches which are secured from Canton, and spread throughout all Yndia and Portugal, together with the returns of the public granaries, and a great many other advantages.
Third: Let his Majesty take great care and consider well whom he sends with this expedition, both the captains, leaders, and commanders of it; for it is very probable—nay, almost certain—that if this be not done, things will fare just as they did in the island of Cuba, and in other countries that were once thickly peopled and are now deserted. If the Spaniards go into China in their usual fashion, they will desolate and ravage the most populous and richest country that ever was seen; and if the people of China be once driven away, it will be as poor as all the other depopulated Yndias—for its riches are only those that are produced by a numerous and industrious people, and without them it would not be rich.
