His brother, the Adelantado, persuaded Columbus to retire from the crowd and himself assumed the whole weight of the assault. The loyal part of the crew, however, persuaded him to put down his weapon, and on the other hand, entreated Porras and his companions to depart. It was clear enough that they had the power, and they tried to carry out their plans. They embarked in ten canoes, and thus the Admiral was abandoned by forty-eight of his men. They followed, to the eastward, the route which Mendez had taken. In their lawless way they robbed the Indians of their provisions and of anything else that they needed. As Mendez had done, they waited at the eastern extremity of Jamaica for calm weather. They knew they could not manage the canoes, and they had several Indians to help them. When the sea was smooth they started; but they had hardly gone four leagues from the land, when the waves began to rise under a contrary wind. Immediately they turned for shore, the canoes were overfreighted, and as the sea rose, frequently shipped water. The frightened Spaniards threw overboard everything they could spare, retaining their arms only, and a part of their provisions. They even compelled the Indians to leap into the sea to lighten the boats, but, though they were skillful swimmers, they could not pretend to make land by swimming. They kept to the canoes, therefore, and would occasionally seize them to recover breath. The cruel Spaniards cut off their hands and stabbed them with their swords. Thus eighteen of their Indian comrades died, and they had none left, but such as were of most help in managing the canoes. Once on land, they doubted whether to make another effort or to return to Columbus. Eventually they waited a month, for another opportunity to go to Hispaniola; but this failed as before, and losing all patience, they returned westward, to the commander whom they had insulted, living on the island “by fair means or foul,” according as they found the natives friendly or unfriendly. Columbus, meanwhile, with his half the crew, was waiting. He had established as good order as he could between his men and the natives, but he was obliged to keep a strict watch over such European food as he still had, knowing how necessary it was for the sick men in his number. On the other hand, the Indians, wholly unused to regular work, found it difficult to supply the food which so many men demanded. The supplies fell off from day to day; the natives no longer pressed down to the harbor; the trinkets, with which food had been bought, had lost their charm; the Spaniards began to fear that they should starve on the shore of an island which, when Columbus discovered it, appeared to be the abode of plenty. It was at this juncture, when the natives were becoming more and more unfriendly, that Columbus justified himself by the tyrant’s plea of necessity, and made use of his astronomical science, to obtain a supernatural power over his unfriendly allies.
