Centeno continued always to retreat, and Carvajal to pursue close in his rear, both parties using the utmost possible diligence, insomuch that they every day marched twelve or fifteen long leagues, almost always within sight of each other. After some days, Centeno made a countermarch upon Paria by taking a different road, and even directed his march, towards the Collao, always followed by Carvajal. At Hayohayo[22] Carvajal came up with twelve soldiers belonging to Centeno, who had fallen behind, all of whom he ordered to be hanged. In consequence of these continued rapid marches, several of the soldiers of both sides used daily to lag behind from excessive fatigue, all of whom endeavoured to hide themselves as well as they could to avoid being made prisoners. Finding his force daily diminishing, Centeno complained loudly of his officers and followers for having prevented him from fighting; and as he found the whole country through which he now marched attached to the enemy, he determined to direct his march towards the coast intending to escape if possible by sea. For this purpose he took the direction of Arequipa, and sent off one of his officers named Ribadeneyra to endeavour to procure a ship somewhere on the coast, which he was to bring to Arequipa, that it might be in readiness to embark the whole remnant of the retreating party immediately on their arrival[23]. Ribadeneyra fell in with a ship on the coast which was ready to sail for Chili, of which he easily took possession, and found it well adapted for his purpose.
