was a cruiser
in the Portuguese navy. It was built in Italy using the revenue of a national subscription made after the British ultimatum to Portugal in 1890. It played an important role in the republican revolution of October 5
, being one of the two rebelling cruisers. In 1917 the Adamastor was one of two cruisers sent to Quelimane in Portuguese East Africa. The presence of the cruisers was a decisive factor in preventing the Germans continued advance on Quelimane (a vital port) after the German victory at the Battle of Namakura
. In 1934 it was decommissioned and sold to the merchant marine.
