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 Espana 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.
