Carte du Detroit de Magellan dans laquelle on a Insere les Observations et Les Decouvertes du Capne Byron, du Capne Wallis, et du capne Carteret.

Rare and important chart of the Straights of Magellan, French edition, which
is only found in the second edition of Hawkesworth’s account of the
voyages of Wallis, Carteret, Byron and Cook. This chart is often
mistakenly attributed to James Cook when in fact it is based, as the
title states on Byron, Wallis and Carteret’s discoveries and
information.

John Byron had set out from Plymouth 21st June 1764 with two frigates, the Dolphin (the first vessel to have a copper-sheathed keel) and the Tamar (under Captain Mouat) and accompanied by Philip Carteret as midshipman.

After
arriving in Brazil on 13/9/64 Byron sailed south in severe storms and
icy temperatures, passed Cape Blanco and coasted Patagonia as far as
Port Desire on 14/11/64. The expedition then set out to look for the
mysterious ‘Peys Island’, and when he failed to find it, he decided to
try for Sebald’s Land but was forced back to the Strait of Magellan
19/12/64. At Cape Virgines he was beckoned ashore by some Patagonian
Indians, later reporting that the Indians were eight feet tall, some
reaching nine. This was the source of the myth of the ‘Patagonian
Giants’ which endured for years.
