SS Antilla (1939)

SS Antilla (or "ES Antilla", with "ES" standing for "Electroschiff" electric ship) was a Hamburg America Line (HAPAG) cargo ship that was launched in 1939 and scuttled in 1940.

Antilla was built for trade between Germany and the Caribbean, and was named accordingly. Antilla is a city in Holguín Province in eastern Cuba.

Building
Antilla was launched in Hamburg on 21 March 1939 and completed on 11 July. She was one of three sister ships launched in 1939 for HAPAG. She and her sister SS Orizaba (1939) were built by Deutsche Werft in Finkenwerder, Hamburg, while their sister Arauca was built by Bremer Vulkan in Bremen-Vegesack.

Antilla and her sisters had turbo-electric transmission. Each ship had two oil-fired high pressure boilers that fed a single AEG turbo generator. This produced current for an AEG electric propulsion motor that drove a single propeller shaft.

Maiden voyage
On 15 July 1939 Antilla left Hamburg on her maiden voyage, which took her to the Caribbean. The voyage was hampered by technical problems with her propulsion system but she eventually reached Curaçao in the Netherlands Antilles.

On 9 August Antilla left Curaçao for Galveston, Texas, where she loaded 3,000 tons of sulphur for Europe. On 25 August, while still in Galveston, she received a radio message from Germany that included the code word "Essberger", which was a signal for her Master, Captain Ferdinand Schmidt, to open sealed orders. The sealed orders had been issued to all German merchant ships, and directed them to leave main shipping lanes. Shortly afterwards Antilla received a second radio message with the same code word. According to the sealed orders this was an order for captains to alter their ships' names and appearance, communicate only in code and return to Germany as soon as possible.

Flight and refuge
Antilla left Galveston to bunker at Cartagena, Colombia. En route on 28 August she received a coded radio message that all German ships unable to reach a German harbour within four days should seek refuge in neutral ports. On 1 September, the day Germany invaded Poland, Antilla bunkered at Cartagena and sailed for neutral Curaçao. However, en route Schmidt learnt that Willemstad Harbour was already full of German merchant ships so he and three other German ships changed course for Aruba. In October Antilla discharged her cargo of sulphur at San Nicolaas in the south of Aruba. However, the four ships' anchorage was in Malmok Bay in the northwest of the island.

The Royal Netherlands Navy submarine HNLMS O 14 monitored the German ships in Dutch Antilles waters. Outside Dutch Antilles waters, ships of the Royal Navy America and West Indies Station and of the French Navy patrolled, blockading any German ships from leaving. However, on 9 January 1940 ten members of Antilla's crew signed on to one of the other German ships, HC Horn's SS Consul Horn, which that evening successfully escaped through the Allied blockade. On 29 February the other two ships, Rudolf Christian Gribel's SS Heidelberg (1925) and HAPAG's SS Troja (1922) tried to escape. Royal Navy ships intercepted them so their crews scuttled the two merchantmen to prevent their capture.

Scuttling
On 9 April Germany invaded Denmark and Norway. This increased the fear that the Netherlands would also be invaded, so on 12 April Dutch authorities in Aruba confined Antilla's crew to their ship. On 10 May Germany invaded the Netherlands so the Dutch government ordered the seizure of all German ships in the Dutch Antilles. At 0310 hrs on 11 May a section of Dutch Marines in two boats approached Antilla to board her but Schmidt refused to lower the gangway. The Dutch marines were commanded by a Captain who anticipated armed resistance from the German crew. He therefore postponed the boarding to first light, when a machine gun positioned ashore could provide cover.

The German crew used the delay to start scuttling Antilla. One crewman locked himself in the engine room, opened her seacocks and climbed out through the funnel. Other crew set fire to several parts of the ship. At 0500 hrs the Dutch marines boarded the ship and at 0530 the German crew was assembled on the poop deck. The Marines escorted the crew ashore in a lifeboat and handed them into the custody of the Royal Marechaussee.

At 0600 hrs two Netherlands Coastguard vessels, HM Aruba and HM Practico, reached Malmok Bay and found Antilla on fire. Two of Aruba's crew boarded Antilla, found the engine room and numbers 4 and 5 holds afire, and that it was not possible to reach the seacocks and close them. After the Dutch marines had removed the German crew, Aruba fired two rounds at Antilla from her 37mm gun. By 0650 hrs Antilla was afire from stem to stern and listing 20 degrees to port. Aruba left Malmok Bay at 1130 hrs, by which time Antilla's list had increased to 30 degrees and she was sinking.

Internment
The Dutch Antilles authorities interned as enemy aliens 220 German nationals including Antilla's 35 crew. The Dutch made Antilla's crew build an internment camp on Bonaire to house their fellow detainees. However, the British authorities had agreed to take them and intern them on Jamaica. On 5 July 1940 all 220 detainees were embarked on the British banana boat SS Jamaica Producer (1934). It took them to Jamaica, where they were interned for the rest of the war.

Wreck
Antilla is one of the Caribbean's largest shipwrecks, exceeded by only the 600 ft cruise liners MV Bianca C and SS Antilles. Antilla lies on its port side in Malmok Bay, Aruba in up to 60 ft of water, but with a small part of its starboard side exposed above water. By 1953 storm damage had broken the wreck in two amidships.

Corals and tube sponges have colonised the wreck, which attracts lobsters, hawksbill sea turtles and many species of fish including moray eels and blue tang. In 2010 a large Jewfish was reported living in the forward section.

Antilla is a popular dive site, and has been popular for penetration diving. Storm damage has continued to break up the wreck and some divers consider it now unsafe to enter.

Misconceptions
Popular misconceptions have arisen around Antilla. One is that she was she was secretly a U-boat tender. In fact between her arrival off Aruba in September 1939 and Germany's invasion of the Netherlands in May 1940 the Dutch authorities repeatedly searched Antilla for weapons and found none. One source even claims Antilla was a tender for Operation Neuland, despite the fact that this operation was in February and March 1942, 21 months after Antilla was scuttled.

A second misconception is that when the Dutch sought to take over the ship, Captain Schmidt negotiated a 24-hour delay. In fact the delay between the Dutch marines reaching Antilla and boarding her was less than two hours. This was achieved not by negotiation but by Schmidt refusing to lower the gangway and the marines' Captain deciding to wait for daybreak.

A third misconception is that when scuttling the ship, the crew heated her boilers so that the seawater entering through her seacocks caused a boiler explosion, and that this explosion broke the ship in half. In fact between May and August 1940 Dutch divers found that the wreck was intact. It was not until 1953 that it was found to have broken in half, and this was caused by storm damage.
