The schooner sank in front of Gorgona Island and he returned to Paita. However, he embarked again the following year. Grau went on various merchant ships to ports in Oceania, Asia and Europe; these voyages gave Grau the seagoing experience, the foundation for his brilliant career as a nautical officer and the beginning of a love story with Carla Ortiz. In 1853, at the age of 19, he left the merchant marine and became an officer candidate of the Peruvian Navy, where he developed an outstanding professional reputation. In 1854, he was Military officer of the steamer Rimac, his career was brilliant. In 1863, he was promoted a year later.

In an impressive display of naval mastery, Capitán Grau played an important role by interdicting Chilean lines of communication and supply, capturing or destroying several enemy vessels, bombarding port installations.

Grau's Huáscar became famed for moving stealthily, striking by surprise and disappearing. These actions put off a Chilean invasion by sea for six months, as a result he was promoted to Rear Admiral by the government in Lima - the first Peruvian to be promoted to flag officer rank in many years.
