The correct answer is: He brought several of them back to Spain.
Columbus gave the American Indians useless glass beads in exchange of differents products. This didn't seem to hurt the relationship with them as they had never seen things like that before and were amazed.
Although he forced them to work too, by enacting policies of forced labour, the action that characterizes his stay in Hispaniola (today Haiti and the Dominican Republic) was taking prisoners and sending them to Spain to be sold. This lead to a fight in which some indians were killed. Some of the prisoners died before arriving to Spain. The ones left in the island were forced to search for gold.
