Template:Infobox ship imageTemplate:Infobox ship careerTemplate:Infobox ship characteristicsRMS Alcantara was an ocean liner which entered service just weeks before the start of World War I, was converted to an armed merchant cruiser in 1915, and was sunk in combat with the German armed merchant cruiser Template:SMS in the Action of 29 February 1916.
Ocean linerEdit
Harland and Wolff in Govan built Alcantara for the Royal Mail Steam Packet Company.<ref name=SBS>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> She was one of the later members of RMSP's "A-series" of liners, which had begun with RMS Aragon launched in 1905. In common with all of the last four "A-series" ships, Alcantara had triple screws. A pair of four-cylinder triple-expansion steam engines drove the port and starboard pair. Exhaust steam from their low-pressure cylinders powered a Parsons low-pressure steam turbine that drove the middle screw propeller.Template:Sfn
Alcantara was launched on 30 October 1913 and made her maiden voyage in June 1914 on RMSP's route from Southampton to Rio de Janeiro, Montevideo and Buenos Aires.<ref name=SBS/> Alcantara was registered at Belfast. Her UK official number was 132050 and her code letters were JFPR.<ref>Template:Cite book</ref>
HMS AlcantaraEdit
In April 1915 the British Admiralty requisitioned Alcantara and her "A-series" sisters Template:RMS, Template:RMS and Andes to be armed merchant cruisers.Template:Sfn She was armed with eight 6-inch guns, two six-pounder anti-aircraft guns, and depth charges. On 17 April at Liverpool she was commissioned into the Royal Navy's 10th Cruiser Squadron as HMS Alcantara, with the pennant number M 94.<ref name=Log>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Arlanza and Andes were also commissioned into the 10th Cruiser Squadron, which joined the Northern Patrol that was part of the First World War Allied naval blockade of the Central Powers. The Squadron patrolled about Template:Convert of the North Sea, Norwegian Sea and Arctic Ocean to prevent German access to or from the North Atlantic.Template:Sfn
German submarine attacks on ships voyaging to and from Archangelsk created a suspicion that the Imperial German Navy had established a submarine base somewhere in the Arctic. In the summer of 1915 Alcantara was sent to Jan Mayen Island to investigate. She arrived on 3 July and sent a landing party ashore.<ref name=Log/> It found no evidence of enemy activity; only the remains of the Austro-Hungarian North Pole Expedition base built in 1882 and three Arctic fox cubs, which for a short time were taken aboard as pets.Template:Sfn
Battle with GreifEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Template:Location map In January 1916 Alcantara embarked on the 10th Cruiser Squadron's G patrol.Template:Sfn She was due to return to port on 1 March, but on the morning of 29 February 1916 she was northeast of Shetland en route to a rendezvous with Andes she intercepted the Imperial German Navy merchant raider Greif disguised as the Norwegian merchant ship Rena with a home port of Tønsberg, Norway.<ref name=Poole/> At 0915 hrs at a range of Template:Convert Alcantara ordered Greif to stop for inspection, which she did. AlcantaraTemplate:'s ship's company went to action stations, she trained her guns on Greif,<ref name=Wardle>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> closed to 2,000 yards and slowed to lower a cutter to put an armed guard aboard the suspect ship.<ref name=Poole/>
At 0940 hrs Greif increased speed and opened fire.<ref name=Wardle/> One source claims she raised the Imperial German war ensign ("Kriegsflagge").<ref name=Poole/> However, AlcantaraTemplate:'s commanding officer, Captain Thomas Wardle, reported that after lowering the Norwegian ensign Greif fought under no flag. The first shell hit AlcantaraTemplate:'s bridge, disabling her steering gear, engine order telegraph and all telephones and killing or wounding a number of men. Wardle ordered full speed and opened fire at a range of Template:Convert. A messenger was sent aft and got AlcantaraTemplate:'s after emergency steering gear connected.<ref name=Wardle/>
Greif turned to starboard<ref name=Wardle/> and closed range to Template:Convert.Template:Sfn Several German shells hit Alcantara near her waterline, entering her stokehold bunkers and engine room.<ref name=Wardle/> Greif tried to torpedo Alcantara. Wardle reported that evasive action at 1002 hrs allowed the torpedo to pass clear under AlcantaraTemplate:'s stern, but another source states that a torpedo detonated amidships against AlcantaraTemplate:'s port side. A shell from AlcantaraTemplate:'s port after Template:Convert gun hit and detonated the ready ammunition for GreifTemplate:'s after gun, putting it out of action.<ref name=Wardle/> By 1015 hrs Greif was badly afire by her bridge and seemed to have stopped. At 1022 hrs Alcantara saw boats leaving Greif and ceased fire.<ref name=Wardle/>
Greif then fired one more shot, and Alcantara returned fire. The one shot was later attributed to a shell left in the breech of an abandoned gun being fired by the heat of the fire now raging aboard Greif.<ref name=Wardle/>
By 1035 hrs Alcantara was reduced to about Template:Convert<ref name=Wardle/> and her after steering gear was disabled.Template:Sfn Her helm seemed to be jammed hard over to starboard but she was turning to starboard. Wardle ordered his company to cease fire, stop engines, and go to boat stations. The order to stop engines was not received, but flooding in the engine room stopped them. Several of AlcantaraTemplate:'s lifeboat falls had been damaged by enemy fire, so that attempts to launch some boats caused men to be dropped into the sea.<ref name=Wardle/> Alcantara rolled, capsized and sankTemplate:Sfn at 1102 hrs. At least 15 of her boats and a large liferaft floated clear.<ref name=Wardle/>
The Template:Sclass2 light cruiser Template:HMS and M-class destroyer Template:HMS then arrived. Comus proceeded to rendezvous with Andes about Template:Convert away, while Munster started rescuing survivors.<ref name=Wardle/> Greif was carrying a large amount of cork that at first kept her afloat.Template:Sfn Andes and Comus reopened fire on Greif.<ref name=Wardle/> Eventually a large explosion, possibly of ammunition, sank the German ship.Template:Sfn
The battle killed 230 men from Greif and 68 from Alcantara.Template:Sfn Two hundred ten German survivors were rescued.Template:Sfn
