In the name of the most Holy Trinity, Pedro Sarmiento set out in the Capitana's boat, named the “Santiago”, with Anton Pablos, Pilot of the Capitana, and Lamero, the Chief Pilot of the Almiranta, fourteen men with arquebuses, swords, and shields, with provisions for eight days. They started at eight o'clock in the morning, on Friday, the 11th of December 1579, to discover the sea at the entrance of the strait.

From “Puerto Bermejo” we went to the “Punta de la Anunciada”, so named during the former boat voyage. From thence they discovered another point, a quarter of a league S.W., from which the coast turns a little west of S.W. for two leagues, to a point we named “Nuestra Sefiora de la Peña de Francia”. There is, off the point and near the land, a small pinnacle rock. In this distance of two leagues there are two small bays. From “Anunciada” we discovered a cape running out into the sea, on the left hand to S.W. by S. which we named “Cabo de Santiago”.

Continuing our voyage we passed a little to leeward of the “Punta de la Anunciada”, and thence crossed the opening and gulf of “La Concepcion” under sail, steering south. In this opening, two leagues S.E. of “Anunciada”, there is a small island, and, beyond it, a group of seven little islets, the whole covering a space of a league and a half. For two-thirds of the distance we steered south, and for a third S.E., arriving at a bay which we called “Arrecifes”, there being many reefs.
