He starts with the search for El Dorado - which simply meant the gold man' and the appalling genocide of the local people by the Conquistadores. During this, he mentions of course the fact that the savage conquest of the South American continent was made much easier because they had horses.
This led me to start thinking about the logistics of transporting enough horses, with enough food for such a long journey, in the ships they had at the time. So I googled a question and have so far quickly learned that the transport of horses was already a sophisticated procedure in ancient Roman times, but even so, when it comes to the 15th and 16th centuries, and the fact that the journey would have taken months, well, the mind boggles. So far, I have not found the answer and I was wondering whether anyone here knows more. I shall be most interested in any information anyone has.
