Read the passage from a letter by Christopher Columbus. As soon as I had come into this sea, I took by force some Indians from the first island, in order that they might learn from us, and at the same time tell us what they knew about affairs in these regions. This succeeded admirably; for in a short time we understood them and they us both by gesture and signs and words; and they were of great service to us.

–Letter to Gabriel Sanchez, Christopher Columbus
