Query: Great and definitive account

I think this is probably the best account one can read about the momentous trip which began 10 Aug. 1519 at Seville, Spain, and ended at that same city on 8 Sept 1522, when 18 of the men who left on 10 Aug 1519 returned to Seville, to have their names inscribed on a plaque as the first men to sail around the world. The author's research seems to be thorough and he went to archives and to the sites important to the story he tells as he wrote his book. There are no footnotes as such, but there are source notes and a bibliography which satisfies me that this is a competent and trustworthy accoount of a rivetingly daring expedition. It is at times compellingly exciting, to such an extent that one had to remind oneself that they did find the strait which bears Magellan's name and did get thru it. This book is a winner.
