**NRP *Adamastor*** was a small [unprotected cruiser](/source/Unprotected_cruiser) of the [Portuguese Navy](/source/Portuguese_Navy) that was [launched](/source/Ceremonial_ship_launching) in 1896 and remained active until being [decommissioned](/source/Ship_decommissioning) in 1933, being the only ship of its class. The vessel played an important role in the [5 October 1910 revolution](/source/5_October_1910_revolution) in the [Kingdom of Portugal](/source/Kingdom_of_Portugal), which saw the fall of the [monarchy](/source/List_of_Portuguese_monarchs), and later took part in actions in [Portuguese Africa](/source/Portuguese_Guinea) during [World War I](/source/World_War_I).

## Technical details

### General characteristics

The cruiser was built in [Livorno](/source/Livorno), [Italy](/source/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](/source/Beam_(nautical)) 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](/source/Deck_(ship)) 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](/source/Naval_rating). 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]

### Armament

*Adamastor*'s armament included two 150 mm and four [105 mm Krupp naval guns](/source/10.5_cm_SK_L%2F40_naval_gun) on the main deck, along with two [47 mm Hotchkiss guns](/source/QF_6-pounder_Hotchkiss) on the [bridge](/source/Bridge_(nautical)), and [Nordenfelt machine guns](/source/QF_6_pounder_Nordenfelt). The ship also possessed three [torpedo tubes](/source/Torpedo_tube).[2][3]

### Propulsion

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](/source/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](/source/United_Kingdom) in 1890, being prevented from making a land route from its two colonies of [Angola](/source/Portuguese_Angola) and [Mozambique](/source/Portuguese_Mozambique).[4] It was [laid down](/source/Keel_laying) in January 1895 and [launched](/source/Ceremonial_ship_launching) in July 1896, before being completed in August 1897.

In 1897 the ship was deployed to the [Moroccan](/source/Morocco) coast, along the with ironclad *[Vasco da Gama](/source/Portuguese_ironclad_Vasco_da_Gama)* and Spanish ships, to hunt [pirates](/source/Piracy). The Portuguese light cruiser ran aground on a rock in [Hong Kong](/source/Hong_Kong) in 1906. The rock and the channel where the rock is located at later named after the cruiser as [Adamasta Rock](/source/Adamasta_Rock) and [Adamasta Channel](/source/Adamasta_Channel).[5] Around 1908 she visited [Portuguese Timor](/source/Portuguese_Timor) and stopped in the [Dutch East Indies](/source/Dutch_East_Indies).[6]

When the [5 October 1910 revolution](/source/5_October_1910_revolution) broke out in [Lisbon](/source/Lisbon), the [Portuguese Navy](/source/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](/source/Necessidades_Palace) of the [King of Portugal](/source/List_of_monarchs_of_Portugal) along with the cruiser *São Rafael*.[4] Thus the cruiser would become a symbol of the revolution.[7]

During [World War I](/source/World_War_I), Portugal took part in fighting against [Paul von Lettow-Vorbeck](/source/Paul_von_Lettow-Vorbeck)'s troops during the campaign in eastern Africa. In 1917, [German](/source/German_Empire) 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](/source/Quelimane), at which point the Germans decided not to attack the city.[8]

*Adamastor* [ran aground](/source/Ship_grounding) in October 1929,[9] but was refloated and returned to service[10] before being [decommissioned](/source/Ship_decommissioning) in 1933.
