Howard Zinn, A People's History of the United States Chapter 1 Columbus, The Indians, and Human Progress

An excerpt by Bartolomé de las Casas, a young priest who participated in the conquest of Cuba.

. . . mountains are stripped from top to bottom and bottom to top a thousand times; they dig, split rocks, move stones, and carry dirt on their backs to wash it in the rivers, while those who wash gold stay in the water all the time with their backs bent so constantly it breaks them; and when water invades the mines, the most arduous task of all is to dry the mines by scooping up pansful of water and throwing it up outside . . . .
After each six or eight months' work in the mines, which was the time required of each crew to dig enough gold for melting, up to a third of the men died. While the men were sent many miles away to the mines, the wives remained to work the soil, forced into the excruciating job of digging and making thousands of hills for cassava plants.
Thus husbands and wives were together only once every eight or ten months and when they met they were so exhausted and depressed on both sides . . . .they ceased to procreate. As for the newly born, they died early because their mothers, overworked and famished, had no milk to nurse them, and for this reason, while I was in Cuba, 7000 children died in three months. Some mothers even drowned their babies from sheer desperation . . . .In this way, husbands died in the mines, wives died at work, and children died from lack of milk . . . and in a short time this land which was so great, so powerful and fertile . . . was depopulated . . . .My eyes have seen these acts so foreign to human nature, and now I tremble as I write . . . .

It is important we understand the reality of the story of Columbus's intent and the results of that intent. Many people boycott Columbus Day, and the accounting presented here, present very good reasons to boycott, protest or at least educate. Columbus's justifications, of course, came from non other than God and the Pope.
