Pedro Sarmiento set out on Tuesday, the 29th of December 1579, with Anton Pablos and Hernando Lamero, Pilots, and twelve men, in the boat “Nuestra Señora de Guia”, with provisions for ten days. They left Port Bermejo to discover the channel, which appeared to turn S.E. from Port Bermejo, and ascertain whether there was a channel and port by which the ships might be taken through safely, without having to return to the high sea.

We made sail before a W.S.W. wind, steering S.E. by E. for 2 leagues, as far as an island which extends a league N.N.E. and S.S.W. It was named “Los Innocentes”, because we left it the day after their feast, and followed the channel S.E. another 4 leagues to a point on the east coast to the east of the inlet of La Concepcion. Behind this point, which we named the point of “San Juan”, to the north, the coast forms a creek, where we made fast and slept there, stationing a good guard, as we always did.

To the S.S.E. of the island of Los Innocentes there is a large entrance to a channel which, in our belief, is the one which leads from the bay of Guadalupe, as before said.

To the north-east of the Innocents there is a large channel, where we stopped and remained that night, and which we believed to be the one which comes from the bay and channel of San Andres. A league to the N.E. of the point of San Juan there is the mouth of a channel, which should be the channel of San Andres coming from Concepcion.
