The cruiser was built in Livorno, Italy. The technical details of the ship were discussed in an 1898 issue of the supplement for the Scientific American magazine. It had a length of 73.8 meters (242 ft 2 in), beam height of 10.7 meters (35 ft 1 in), and depth of 6.5 meters (21 ft 4 in). The hull of Adamastor was made of steel and the lower decks had watertight compartments. Two electrical ventilators were provided to ventilate the ship in hot climates. The ship had a total crew of 237 officers and ratings. The quarterdeck included the captain's chambers, while the officer accommodations were located aft below the main deck. The top forecastle was occupied by the quarters of the petty officers and sailors.[2][3]
The ship was powered by either two or four cylindrical engines that were placed in separate watertight compartments and were rated at 4,000 horsepower (2,983 kW). Around 400 tons of coal were kept aboard Adamastor.[2]
Operational history
The ship had originally been built with money from public subscription in order to restore Portugal's honor after being humiliated by Great Britain in 1890, being prevented from making a land route from its two colonies of Angola and Mozambique.[4] It was laid down in January 1895 and launched in July 1896, before being completed in August 1897.
When the 5 October 1910 revolution broke out in Lisbon, the Portuguese Navy would play an important role, in particular the crew of the Adamastor who rose up simultaneously as a revolt begin in the capital. Among the supporters of the revolution were the crew of three cruisers, including Adamastor, which helped to bomb the Necessidades Palace of the King of Portugal along with the cruiser São Rafael.[4] Thus the cruiser would become a symbol of the revolution.[6]
During World War I, Portugal took part in fighting against Paul von Lettow-Vorbeck's troops during the campaign in eastern Africa. In 1917, German forces entered Portuguese Mozambique. Although they defeated the Portuguese and British land forces, Adamastor and another cruiser were sent to the important port of Quelimane, at which point the Germans decided not to attack the city.[7]
