Our brigantines were now so far advanced towards completion, that they had merely to be rigged. For each brigantine a number of spare oars had been made in case of need. The canal in which these vessels were to be launched, and through which they were to be conveyed into the lake, was now also sufficiently deep and wide to swim these vessels.[20] Cortes now, therefore, began to make active preparations for the siege of Mexico. He issued orders to all the townships which lay in the vicinity of Tezcuco, and were in alliance with us, for each of them to furnish him with 8000 copper points for our arrows, to be made after the model of our Spanish ones, of which some were sent them for that purpose. They were also to furnish an equal number of arrows, which were to be made from a wood particularly adapted for that use, and they received some of our Spanish arrows to work by. He allowed them eight days for the making and delivery of these; and indeed both the arrows and the copper points arrived at Tezcuco in the time specified. Our stock of these now consisted of 50,000 pieces, and the arrow points made by these people were even better than those we brought from Spain. Cortes then ordered Pedro Barba, who commanded the crossbow-men to divide the arrows and copper points among his men, and see that every man fixed the points neatly to the arrows, and attached the feathers with strong glue. Every crossbow-man was also to furnish himself with two closely twisted cords for his bow; further to provide himself with a number of spare nuts for the bows, that if one should crack or fly off he might have another in readiness. The crossbow-men were also to exercise themselves in shooting at heaps of earth to ascertain the strength of their bows. Care was therefore taken that they should not want for Valencian strings to twist the cords of, for the vessel of Juan Burgos, which had recently arrived from Spain, had fortunately brought a good supply of these as well as of bows, powder, muskets and other arms, besides a quantity of horseshoes. In the same way our cavalry were ordered to equip themselves, have their horses fresh shod, and to exercise them daily in all manner of cavalry evolutions.
