Dutch Navy WW1

The Dutch Navy in 1914, a shadow of its past glory

Situation at home

In 1914, the Dutch fleet was in the same position as Scandinavian countries, having only one coast defense squadron to defend its shores, totally outclassed by the Hochseeflotte, the expansionist Reich being the most feared at the time. west, while the bulk of his naval forces resided in the “pearl of the empire”, Indonesia, and had to face the rise of Japan’s empire, considerably strengthened since 1905 in morale, confidence and capabilities. The Achin war had, by its duration (1873-1904), singularly impoverished the treasury, and naval budgets were curtailed.

The metropolitan navy could not do much against the German navy, but the real military peril came in the occurrence of the land. On the Dutch Eastside, the Japanese fleet outclassed the squadron of Java, but at least it had to resist until the concurrence of one or all the allies.

However, the prevalent budgetary constraints policy had its limits. Against Japanese appetites, the Russian Pacific Fleet no longer resisted after 1905, while the British Indian Fleet had been withdrawn for the benefit of the Metropolis. The French navy of Indochina could only deploy minor units, while the Chinese fleet was inoperative, crippled after 1894, and stranded because of its division between local warlord and the regime’s corruption, rarely able to fight. In 1908, a vast rearmament plan was decided: Four coastal 7000 tons battleships and are submersible plus destroyers. The main focus was on minefields, to immobilize the adversary or force an enemy to pass through areas beaten by coastal artillery, mined and easily defended by few ships. The classic “Salamine trap”.

A royal commission was appointed to study the question of defense of the East Indies, and it recommended in 1913 the start of construction of five 20,000 tons dreadnoughts for this sector, but also four for the metropolis, assisted by about fifty destroyers. There were also dozens of torpedo boats and large submersibles, as well as new minelayers. It was also planned to reinforce Batavia, transformed into a naval base with the addition of coal reserves and defended by three forts. Despite the political opposition that provoked a crisis, the plan was not voted on until August 1914. The outbreak of the war made it obsolete.

Here are Dutch naval force at the eve of WWI:
7 Coastal Battleships: The De Zeven Provincien (1909), the Kortenaer (1894), a survivor of the Evertsen class, and the 5 class Konigin Regentes (1900-06).

35 Raiders: 16 Class G (1904-14), 3 Class Draak (1906), 2 Class Ophir (1901), 5 Class Hydra (1900), the Makjan, and 4 Class Ardjoeno (1888). Second class: The XXI (1890) and 3 class K (1905). 8 others planned under construction.
Submersibles: O1 (1905), O2 class, and K1 (1913). Two others planned.

The Dutch Navy during the war


The Batavian Navy during the First World War:

The neutrality shown by Holland in 1914 was one of the most difficult to hold: Neighbor of the Second Reich, whose armies would have made a mouthful of her, granting herself valuable opportunities on the North Sea, it should also spare the Japanese, neutral too, but who could then very well switch to the camp of the triple alliance. Its imposing maritime trade, with Germany as well as with Great Britain, was also a powerful obstacle to any engagement.

With the blockade imposed by the English and the severe control of the merchant traffic, economic activity was significantly weakened. In practice, the reception of German cargo ships was almost impossible, a consortium of Batavian merchants committing themselves to it and Great Britain keeping the right to “blacklist” the offending importers, particularly by weighing on coal imports allocated to companies.

However, blockades were always possible, thanks in particular to the intermediaries represented by the Scandinavian countries. Thus Germany received millions of tons of Norwegian iron passing through Rotterdam. A large illegal food trade also developed illegally, with the black market inflating prices and freeing appetites from many adventurers… The Royal Navy also did not hesitate to pursue German blockade enforcers in Dutch waters; Those who passed through the Batavian ports were not in principle worried.

In 1917, with the development of submarine warfare, the Dutch were not spared and lost, despite their safe conduct, 230,000 tons of commercial ships, worth 147 million pounds sterling. New ships constructions were launched: In 1916, two cruisers of the Java class, completed in 1925-26, 6 torpedo boats class Z, 2 submersibles class O6, the KII, 2 class KIII, 3 class KV, 3 class KVIII (these last completed after the war, in 1919-23), 2 trawlers and 5 tugs converted as minelayers, 2 Van Meerlant class minelayers. In addition, two submersibles, a German type UC and an English type H were recovered after sinking in home waters and were reused by the Navy, under the names of M1 and O8.

WW1 Dutch submarines


Not many were present in home waters to change the course of history. Coastal in nature, they were held in harbour defense for the duration of the war. All in all, seven submarines, and in addition a single one (K1) was deployed in the Dutch east indies (see later). In addition, the Dutch Netherlands Navy had a single German Type UC I submarine in service, called M1 after being recommissioned, and a single British H-class submarine, called O 8. The first was the ex UC-8, stranded near the Frisian island of Terschelling on 6 November 1915 and captured, after her crew opened the valves to sink her. She was recovered and repaired, interned, and then acquired from Germany, entering service in January 1917. Her fate is not known with certainty, she was either scrapped after the war or kept as a training boat.

O 8 was the ex H-6, stranded also, but on Schiermonnikog on 18 January 1916. She was refloated and interned, because the country remained staunchly neutral during the conflict. By agreement, when was acquired by the government and pressed into commission in May 1917. She had a long service time, for whole the interwar, not surprising due to the quality of these boats (see WW1 British Submarines). In May 1940 she was captured in Den Helder by the Germans. They turned her as the UD-1, used as a training boat, and later was repatriated in Germany. She was scuttled in Kiel in May 1945.

O 1:

The First Dutch submarine, built at De Schelde Yard as a private venture in Vlissingen, after the Dutch Navy purchased plans from Electric Boat Co. He first name was Luctor de Energo, and she was -as anticipated by the yard- purchased by the Navy and renamed Hrms O 1. She was launched in July 1905 but commissioned in December 1906, completion and trials leading to many fixes. Basically a very early commercial Holland boat, she was typical of the type, fast and agile after diving, slow and short range on surface. Initially fitted with a petrol motor, it was replaced in 1914 by a MAN diesel engine. It saw service during the war as a coastal/training boat and was stricken in 1920. She displaced 105/124 tonnes and was capable to reach 8 knots on surface, 6 underwater, and carried a single 250 mm TT (9.8 in).

O 2 class:

HrMs O2
O2 class: O2-O5 were basically the main submarine class in service when the Netherlands went at war in August 1915. They were all built at De Schelde, based on plans prepared by the British engineer Marley F Hay, and Whitehead & Co in Fiume (a famous torpedo manufacturer since the 1870s). Laid down in 1909-1912 they were completed in 1911-1914, but already obsolescent as the war started. Despite of this, they were modernized after WW1 and maintained in service as training/coastal submersibles until stricken in 1931-35.

Displacement: 130/150t
Dimensions: 31.1 x 3.1 x 2.9 m (102ft x 10ft 2in x 9ft 6in)
Propulsion: 1 shaft MAN diesel 6-cyl, 1 electric motor 350/200 shp, 11/8.6 knots
Range: 500 nm/10 kts, 26 nm/8.6 kts underwater
Armament: Two 450 mm TTs (17.7 in)
Crew: 10

O 6 class:

Conway’s profile
Wartime submarines (launched 1916), comprising O6 and O7. They were born from different yards (O7 from Fijenoord) and sufficiently different for some authors to have them separated.
O 6 was indeed of the Holland type, O 7 of the Hay-denny type. The O 6 was ordered on 8 May 1913, laid down in May 1914 in Flushing, De Schelde, launched on 10 June 1915 or 15 July 1916, comm. on 5 December 1916. During the war she remained based in Den Helder. In early june 1920 she made a trip to Norway, visiting Odda, Bergen, Gudvangen and back. In June 1923 she was used by Professor F.A. Vening Meinesz for gravity measurements in the North Sea. Without no other notable events she was decommissioned in November 1936. O 7 was ordered on 8 May 1913, laid down on 12 May 1914 the O 7 in Rotterdam, Maatschappij Fijenoord, launched on 22 July 1916 and commissioned on 23 December 1916. Nothing notable happened during WW1 as she was posted as O 7. On 18 May 1927 she collided with the Swedish steamer Scania off the coast of Texel, but survived and was repaired. From 1935 she was used only as a training vessel, until December 1936 decommissioned and sold for scrapping, but still extant in 1940, when the Germans invaded the Netherlands. Captured, she was of no use and stayed idle, until sinking on 2 May 1944 in Den Helder because of water leaking and scrapped after the war.
