It was built for the purpose in the city of San Carlos de Ancud and commanded by John Williams Wilson, a British-born Chilean captain.

They called at a place known as Puerto Americano or Tangbac, where two American ships were anchored: the schooner Betzei and the brig Enterprise, both seal hunters.

On July 26, they tried to pass Taitao Peninsula, but bad weather, together with a failure of the rudder and a starboard crack drove them back to seek shelter again in Puerto Americano, arriving there on August 2.

The Enterprise was retired from Puerto Americano to a beach nearby and the next day, when the schooner Ancud had left to continue his journey, was reported to Americans that if they were meeting them again in Chilean territory without a formal permission of local authorities they will proceed to confiscate the boat.

When they reached Punta Santa Ana in the Strait on September 21, 1843, all the crew of the schooner went ashore and took formal possession of the surrounding territory on behalf of Chile and started the process to build Fuerte Bulnes.
