Battle of Gotland (July, 2, 1915)

Lake Tanganyika
Reichsmarine vs Russian Navy

Fire on the Baltic

The fact that the Baltic did not saw naval major battles like Heligoland or Jutland don’t have to mask the myriad of naval actions that occurred in this war between the Russian Navy -albeit reduced after the crippling losses of 1905 in this theater- and the powerful Reichsmarine, that kept the bulk of the Hochseeflotte facing the north sea, waiting for opportunities to engage the Royal Navy.

This battle of Gotland, also called Battle of Åland Islands occurred nearby one of the largest island (if not the largest) of the baltic sea, the fortress guarding Swedish east coast. These already seen (and will see) many other clashes between German and Russian ships, but also testified of age-old clashes between Russians and Swedes in the past. This was a serious gun battle between cruisers of many types from both sides, the Germans loosing eventually the Albatross, and the Russian retiring with two badly damaged armoured cruisers.


Blueprint of the SMS Albatross

The day before the battle of Gotland, Kommodore Johannes Von Karf had been ordered to anchor a vast minefield off the Aäland Islands, closing the Gulf of Bothnia. He departed with the minelayer cruiser Albatross (frigate captain Fritz West), escorted by the armoured cruiser Roon, and the SMS Augsburg, Lübeck, as well as 12 destroyers. Following Odensholm’s action on 26 August, the Russians seized the codebooks and signals from the Hochseeflotte, and thus intercepted messages, enabling them to know the squadron’s exact departure. On the 2nd, a force comprising the armoured cruisers Admiral Makaroff and Bayan, assisted by the cruisers Oleg and Bogatyr sailed from Saint-Petersburg under the orders of Rear Admiral Mikhail Bakhirev in the hope of intercepting it. This force was joined and assisted by a British submersible.


SMS roon (1907), this class preceded the Scharnhorst and was strongly related

On the morning of the 2d, the German fleet was mooring mines in front of the Aaland Islands, when the black plumes of the Russian squadron were spotted. Immediately the operations in progress were abandoned, and the ships turned and headed south. However, the time to carry out the maneuver, the Russian cruisers were at gun range, and the slowest cruiser, SMS Albatross was catch and fired upon. The ship only had a few 88 mm pieces to oppose 203 and 152 mm guns on the Russian cruisers. This resembled quickly therefore to a real execution. However, the Roon and two light cruisers replied, but the duel of artillery was not conclusive. The two fleets advanced in parallel, heading south, and arrived off Gotland when Von Karf was informed of the arrival of two other armoured cruisers, the Prinz Heinrich and the Prinz Adalbert, which just sailed to the rescue. The balance was about to swap in favor of the Germans.


The minelaying cruiser Albatross failed after her fight against the Oleg and the Bogatyr.

The Russians for their part, brought out the Rurik, one of the most powerful armoured cruisers in the world, assisted by the destroyer Novik, no less formidable. They just set sail at the time the news of the clash off the Aaland Islands, and force-steamed south-west in an attempt to cut off Von Karf’s retreat. The threat was very serious, and the battle began to swap again, and this time, taking on a disastrous scale for the Germans. The Albatross, caught by the Oleg and Bogatyr, was severely hit, her machines partially drowned, drifting, silenced, crippled, and eventually ran aground on a sand bank off Gotland. Meanwhile Von Karf from his flagship Admiral Roon, was attacked by the Bayan and Makaroff, being hit several times and severely damaged. Getting the news of the arrival of the Rurik Von karf decided to break off the fight and retreat south-east towards Königsberg.


Russian cruiser Bayan

The two German armoured cruisers which came to reinforce, just informed of Von Karf’s decision to retreat, decided to head south, but the Prinz Adalbert was intercepted by British submarine E9 waiting in ambush, and was torpedoed. She survived thanks to the promptness of her crew, clogging the leaks with Makaroff slippers, and thus avoiding the entire engine room being submerged. The cruiser dragged herself to the coast and ran aground on a sand bank off Danzig. She would be later towed and repaired, but shortly after her return in service, on 23 October, she will be torpedoed once again, this time by E8, and sent to the bottom for good.


Russian Cruiser Oleg

In the end, Russian losses were difficult to evaluate but it is clear that the Bayan and Makaroff received some hits. The exact balance of the Russian side remains mysterious. In any case, the verdict was severe for the Germans, who, without ever suspecting being spied on or capable to explain the sudden arrival of the Russians to this point, lost the Albatross, which they never attempted to tow. Her surviving crew reached the boats in good order, sailing to the coast of Gotland (Sweden), and from there rejoined Germany afterwards. The Albatross was towed to be broken up later in 1921. The Germans were also deprived of the Roon and Prinz Adalbert, in repairs for long months. Worst still, mines of the Aaland Islands were quickly raised dredged by the Russians. So in the end, we have to see this battle of Gotland as a Russian tactical and strategic victory (three ships eliminated and a minefield).

Cruiser Minin (1866)

The oldest cruiser worldwide ?

The Minin (Минин) was still in service in 1914. By that time, she was 48 years old, and by the time the war ended, get passed half a century. Yet she was not a museum ship, but fully active the whole time for the Russian Empire. Fact is, she was started in 1863 as a sister ship for the Kniaz Pozharsky, an ironclad. But contrary to the former, she was redesigned as a turret ironclad as the broadside ironclad genre was already obsolete. In this first configuration she looked as a three-masted ship, but with a low-freeboard, as HMS Captain, the idea being water was a protective barrer by itself (and the Captain still had not sink by that time), proving how far this hull concept was dangerous. Bacause of these modifications, the Minin was eventually launched at Baltic Works, Saint Petersburg in 1869 but completed in 1878, nine years after a complete reconstruction ! “Minin” was named after Kuzma Minin, a famous figure of the Russian renaissance, helping Pozharsky against the Poles at Moskow.

Design of the Minin

In its original configuration, she was a 95 m wooden ship with a hull sheathed with copper to reduced biofouling. She was propelled by a vertical compound steam engine, single propeller and a dozen coal cylindrical boilers. This gave 5,290 hp (3,940 kW) for a 14.5 knots top speed, for what she carried 1000 tons of coil, reaching about 4200 nautic miles. Fully rigged, she can reached as much as 4 knots, and complement steam power by sail. In this case, the funnel could even be lowered to reduce drag.

Original protection comprised a belt 6–7 in thick (152–178 mm) and a deck 1 in (25 mm) with wrought iron. Her armament then comprised four 8-inch (203 mm)/22 cal., twelve 6-inch (152 mm)/23 cal. and four 87-millimeter (3.4 in) rifled breech-loading guns. In 1899, her armament was modified for the third time (out or six), with the same four 203-мм/30, but only six 152-мм/45, six 75-мм/50, eight 47-мм/44, four 37-мм/23, four 7,62-мм MG and two 64-mm saluting guns. In 1909 shorty after her total second reconstruction, she had ten 152-мм/45, six 75-мм/50, eight 47-мм/44, four 37-мм/23, four 7,62-mm MG.

1912 Complete Rebuilding as Ladoga

She was refitted in 1887, which prolongated her use until 1906. In 1906 however she was demoted from cruisers of the 1st rank to training ship. In 1908 she was refitted as a floating mine warehouse. In 1909 she was renamed Ladoga in to free the name for more modern ships. In the fall, she was enlisted in the Baltic detachment of minelayers. But it’s only in October 27, 1912 that she emerged, converted as a minelayer (battery deck rails, outboard stern slopes), new boilers produced by the Black Sea Mechanical and Boiler Plant. Her rigging was reduced to 2 pole masts, and crucially the armament was down to just four 47-millimeter (1.9 in) guns. Everything on board was modified to handle and carry 1000 mines.

Service in WW1

Ladoga in her new assignation participating in laying the great mine barrier of the Gulf of Finland in 1914. She performed several other missions and was eventually sunk in the Baltic on 15 August 1915. The irony was she sank one the mines previously laid by German minelayer submarine SM UC-4. She was blown up on a mine placed near the island of Ere which dug a hole in the bow on the port side. As a result of a rapid flooding of the boiler room, a boilers explosion followed, after which the ship sank, but fortunately only 5 crew died.

WW1 Japanese Destroyers

Japan (1898-1919)
About 180 ships

A newcomer in destroyer design

WW2 Japanese destroyers were certainly among the world’s most powerful since the Fubuki in 1926. Just like Russia showed the way in 1910 with the Novik, Japan was at the forefront in destroyer design, with speed, firepower, and aggressive tactics matching over-the-top torpedoes like the deadly “long-lance”. The prewar models were rather small, high seas TBs, while from 1917, Japan launched in a frenzy dozens of large oceanic destroyers. This story started very early on, like many other nations, with torpedo-boats. In August 1914, 62 destroyers were in service, all classes confounded.

From 1879 to 1895

The first contract on behalf of the IJN was awarded as early as 1879. Because of previous events, little funds, only small series of modest ships could be ordered at a time. The first four were built at Yarrow, dismantled, shipped and reconstructed at Yokosuka, and retired in 1899. What followed was the experimental armoured TB Kotaka in 1885 and about 40 TBs followed from 1885, coastal Yarrow types (50t and 25t), then Japan turned to France and ordered 35m types and Normand 34m types (1894). All has been discarded prior to ww1. Larger Schichau types were later also ordered. The 54t type, 3rd class TBs were the first Japanese-designed ones, in all 26 boats all operational when WW1 began, for coastal defence.

Japanese early destroyer design

At last in 1900 the Ten Years Programme put a plan for dozens of new TBs but also ordered 23 destroyers.
The following classes consisted in the Ikazuchi (6), Murakumo (6), Akatsuki (2), Shirakumo (2), Harusame (7), Asakaze (32), Umikaze (2), Sakura (2), and three ex-Russians. These ships were 275 to 375 tonnes, 63 to 69m long, 5.96 to 6.57m of width, 1.56 to 1.83m of draught, 29 to 31 knots and the same armament of 2x 12 pdr, 4x 6pdr and 2 18 in TTs (450 mm).

Ikazuchi were basically Yarrow ships (like the Akatsuki), Murakumo were from Thornycroft, while the Harusame were all Japanese, after a modified Shikarumo design. Their machinery was still very Thornycroft-esque in style. These 1st generation destroyers were all scrapped in 1920. But the second generation was far more interesting and for the most, was in service in the whole interwar and for many, WW2 as well.

Ikazuchi class (6 ships, 1899)

Yarrow-built, completed 1898-1900. Comprised the Akebono, Ikazuchi, Inazuma, Niji, Oboro and Sazanami. 305 tons, 6000 hp, 31 knots. Few participated in the great war: the Niji, scarcely received and perhaps badly maneuvered by her crew was carried by her own speed and ran aground on a reef. She was salvaged and broken up in 1900, following her only sortie. Ikazuchi was in Tsushima and survived the Russian fire, saw his boiler explode in 1913 and was lost. The Inazuma crashed into a schooner near Hakodate in 1909 and sank it. The Sazanami was also the victim of an accident in 1913. Only the Akebono and Oboro participated in the great war. They became tankers in 1918 and were removed from the lists in 1921.

Murakumo class (6 ships, 1898)

Thornycroft boats, 275 tons (63 x 5.9 x 1.7m), fitted with more powerful machinery to reach 30 knots for 5800 hp. The class Comprised the Murakumo, Shinonome, Shiranu, Usugumo, Yugiri and Kagero.
They were practically built at the same time as the Ikazuchi at Yarrow. They were differentiated by smaller dimensions and a reduced displacement of 305 to 275 tons, and less power available. The Shinonome was hit hard by the first typhoon that almost caused its destruction, but was repaired and lost in another typhoon in 1913. The Murakumo survived the same typhoon in 1909. The Yugiri was almost destroyed in Tsushima, but all participated in the Great War and were removed from the lists between 1921 and 1927.

Akatsuki class (2 ships, 1899)

Virtually repeats of the Ikazuchi, but with boilers giving extra pressure, for 6500 hp (500 hp gain) and 31 knots. 363t boats, same lenght and width but greater draught. Akatsuki and Kasumi were launched and completed 1901-1902.

Shirakumo class (2 ships, 1901)

Japanese design, slimmer and lighter (thus faster) than the following design (see below). Comprised the Shirakumo and Asashio.

Harusame class (7 ships, 1901)

These first 100% Japanese destroyers were derived from the Shirakumo class, which only counted two ships. The class comprised the Shirakumo and Asashio. Both were Japanese-designed, still with some British influence. The Shirakumo were 342 tonnes, 65.8m long 6.34 m wide, whereas the Harusame were substantially larger and wider, while keeping the same draught and different engines. However performances of the former were better, their VTE engines (extra boiler) being able to develop 7000 hp for a reduced weight (33 tons less).

Externally they shared the same silhouette: Long, slim hull with a front turtleback, small platform above the armoured conning tower with the 12 pdr gun and backup bar, command and observation devices. The two single tubes were behind the serie of four funnels squared by the four 57 mm guns while the 75 mm was at the rear end;
Armament comprised the standard two 60mm (12 pdr, four QF 47 mm (6pdr) and two 457 mm torpedo tubes. The class launched 1902-1905 and completed from 1093 to 1905 comprised the Arare, Ariake, Fubuki, Harusame, Hayatori, and Murasame.

In 1905 they all fought in Tsushima. The Harusame was severely damaged by Russian fire and managed to survive. She was lost in 1911 in a typhoon. Hayatori was blown up on a mine during the blockade of Port Arthur. So 5 the units left participated in the Great War, being subsequently deleted from active lists in 1922-24-25.


2nd class destroyer Isononome.

All these 24 ships were active (home waters) and retired from service in 1920. They mostly built knowledge and expertise from these different designs that help creating a larger, second generation destroyers.

Asakaze class (32 ships, 1905-1907)

IJN Ushio at Vladivostok
IJN Ushio at Vladivostok

Still 1st generation destroyers, they were the first mass-produced Japanese destroyers. They looked very much like copies of the previous Harusame, as part of an “emergency plan”, 1904 special war programme ordered in June, September 1904 and 1905. Following this, there were attempts to devise oceanic types, but budget and time constraints had the Navy adopting a double standard, with medium (2nd class types) like these ones, fit for coastal water. They indeed participated in WW1 as a defence fleet and were all broken up in 1923-1930, some being converted as minesweepers in between.

The Asakaze were substantially larger than the previous ships, displacing 381 tonnes for 450 at full load, 72 m long, but only lightly larger (4 cm), and the same draught. They derived from a previous Thornycroft design. They had two shafts with 4-cylinder vertical watertubes engines, four Kampon boilers which produced a total of 6000 hp, and the same 29 knots as above. Armament was heavier, with improved guns, two 3.1 in/40 (80 mm), and four 3.1/28 calibers, and like previous classes, two single 457 mm (18 in) centerline torpedo tubes. Complement was also larger, 70 men.

For the first time, Yokosuka could not fulfill the order, which was passed to civilian yards, gaining experience in that area. But because this was a first, some yards had troubles getting the construction right in time, and meny of these ships were launched in 1906, as the design was already obsolete. Ships that were rearmed as minesweepers get two 4.7 in/45 guns and two 3.1in/40 guns for earlier classes.

Asakaze specifications
Dimensions 72 x6.6 x1.83 m
Displacement 381 T FL
Crew 70
Propulsion 2 shafts VTE engines 6000 hp
Speed 29 knots
Armament 2x 3.1/40, 4x 3.1/28 in, 2x 18 in TTs (457 mm).

Umikaze class (2 ships, 1911)

This was the first oceanic class of destroyers designed and built in Japan, at Maizuru NyD and Mitsubishi (Nagazaki) Naval yard. This design call D-9 were ordered in 1907 as a “proof of concept” in modern standards, but they were only launched in 1909, their blueprints being redrawn and modified in between. First, they were given powerful turbines, Parsons designs built by Mitsubishi, three of them, each one connected to a single shaft, the lot fed by 8 Kampon boilers, for a whooping total of 22,500 hp, enough to reach 33 knots. These were mixed boilers, so 250 tons of coil and 178 tons of oil were stored on board, which gave a range of about 2700 nautical miles at 15 knots.

Complement was double than previous ships, and armament comprise two light cruiser size 4.7 in guns (120 mm) of 40 calibers, and five 3.1 in (80 mm)/40, and two twin 457 mm (18 in) TTs on the Umikaze, whereas Yamakaze had three single tubes. They were delivered only in March 1910 and January 1911 due to delays or delivering the turbines. Their armament was reduced when converted as minesweepers in 1930. Both were stricken in 1936 and broken up. The design was expensive and the next oceanic class was scaled down.

Umikaze specifications
Dimensions 98.5 x8.5 x2.7 m
Displacement 1030/1150 T FL
Crew 140
Propulsion 3 shafts Turbines, 8 boilers 20500 hp
Speed 33 knots
Armament 2x 4.7in, 5x 3.1 in, 4x 18 in TTs (457 mm).

Wartime Production

The war production was not at the level of those of the RN and the USA: In the 10 Kaba, succeeded the 4 Momo, the 6 Enoki, the 4 Isokaze, the 2 Urakaze, the 2 Tanikaze. 28 destroyers in total. All saw the conflict. On the other hand, the 1918 plan tried to catch up with the allied navies, seeing the construction from 1919 to 1924 of the Minekaze, Momi, Wakatake and Kyokaze classes, all impressive oceanic destroyers that will actively participate in WW2.

Sakura class (2 ships, 1914)

Sakura at Sasebo, Taisho, 1918
Sakura at Sasebo, Taisho, 1918

The Sakura inaugurated a new category of “second class” destroyers, more economical than the “first class”. They were clearly out of the initial program, including only ocean-going ships of the Umikaze type (1910), and were commissioned mainly for budgetary reasons. The Sakura and the Tachibana were thus lighter than 400 tons, but also less slower.
They were good compromises between the coastal destroyers of the Asakaze type and previous ones coming from Yarrow and the ambitious Umikaze. They were followed by the Kaba class in 1915, 10 heavier units of 60 tons with a larger draft.

Sakura specifications
Dimensions 83,6 x 7,3 x 2,3 m
Displacement 665t – 850t T FL
Crew 92
Propulsion 3 shafts, 3 VTE, 4 kampon boilers, 9500 hp.
Speed 30 knots
Armament 1x 4.7in, 4x 3.1in, 4x 18 in TTs (457 mm).

Kaba class (11 ships, 1915)

When the was broke out, Japan had only two modern destroyers for oceanic deployment, the Sakura and Tachibana, so the government approved the Emergency Naval Expansion Budget FY1914 and ten more destroyers had to be built in 8 different civilian yards with conventional coil boilers and VTE engines (also to speed up things) rather than turbines. They were indeed laid down in the end of 1914 and launched in early 1915, completed just 1-2 month after and all named after trees.
This Kaba class was so successful that the French ordered 10 more for their own fleet in the Mediterranean, the “Arabe”, all named after peoples living in French colonies. All the Kaba were all removed from service in the 1932.

Urakaze at Wuhan, China in 1930-1933

Urakaze and Kawakaze were built in Yarrow, a first since the beginning of the century. They were designed to test new 533 mm torpedo tubes and oil-fired turbines. The kawakaze was, however, awarded by the British government to the Italians even before its completion. The name will be carried by the second building of the Tanikaze class in 1918. The Urakaze, ordered in 1912, saw its construction delayed and it will be finally delivered only in 1919. It will serve a long service until 1936, and its hull will be cast by a US Navy aircraft in 1945.

The Isokaze class included the Isokaze, Amatsukaze, Hamakaze and Tokitsukaze. They were launched and completed in 1916-17. They were ranked first-class destroyers, and derived from the 1910 Umikaze, as “squadron leaders.” They were much heavier (400 tons) and larger, and gave up their secondary artillery for two additional TTs. In 1935, they were all removed from the lists and broken up in 1936.

Momo class

The four Momo (Kashi, Hinoki, Yanagi, Momo), completed in 1916-17 were built in parallel to the Isokaze, with some specific characteristics for the second-class destroyers they were, compared to the Kaba and Sakura. They were the first to showcase an inverted curved bow, specifically Japanese, whose ice-breaking vocation is not an obvious fact, especially turbines and triple torpedo tubes.They were sent to the Mediterranean until 1919 and then served until 1935. The Kashi was transferred to the marine epoch of the Mandchuko under the name of hai Waei in 1937 and returned to service in Japan in 1943 under the name Kali, before being blasted in Okinawa. The Yanagi was used for training and was broken up only in 1947. The six Enoki (Enoki, Nara, Kuwa, Tsubaki, Maki and Keyaki) were derived from it closely and were launched and finished in 1918. They were slightly heavier and more powerful. They were removed from the lists in 1932 and 1938 for two of them, transformed into minesweepers.

Enoki class (6 ships, 1918)


Kuwa in trials in 1918 off Yokosuka

All named after trees, these six destroyers were part of the FY1917 emergency procurement budget, bound to operate in the Mediterranean. They were all laid down in 1917 and completed in 1918, built in Yokosuka Naval Arsenal, but also Kure, Sasebo and Maizuru naval arsenals. They were virtually repeates of the previous Momo (same blueprints) but were modified with a new bow and better armour. In general experience dictated their hull to be strengthened to handle heavy seas. For propulsion their relied on proven Brown-Curtis geared steam turbine engines coupled with mixed-fired boilers. Armament was also identical to the Kaba, with three QF 4.7 inch Gun Mk I – IV guns and triple TT banks. Due to their very late arrival, these ships were never deployed in their intended destination and instead spent their career near the Japanese home islands. Two were converted as minesweepers in 1930. They were all retired in 1934-36.
Specs are near-identical to the Kaba.

Kawakaze class (2 ships, 1918)

Tanikaze
Tanikaze (谷風 “Valley Wind”)

The large destroyer leaders (Kawakaze, Tanikaze, named after winds) were built in Maizuru and Yokosuka, as part the IJN ‘8-4 Fleet Program’ FY1915. Basically they were escort vessels for the new Nagato class battleships and Tenryū class cruisers. One of the two was funded by the Italian government after reception of the Kawakaze (now Audace). These were large ships (1600 tons fully loaded), roomy enough to fit a set of two large shaft steam turbine fed by 4 boilers producing 34,000 ihp (25,000 kW) total, enough to reach a blazing 37.5 knots (69.5 km/h) speed. Armament also comprised the new new Type 3 120 mm 45 caliber naval guns and also new 533 mm three double launchers and AA armament of two 6.5 mm machine guns. Both missed ww1 as Kawakaze was completed in November, 11, 1918 and the second 30 January 1919. They served in the interwar until 1934-35.

Most were launched however from 1919 to 1921 and of 28 ships planned (all named after flowers) 7 were cancelled, 10 scrapped. Most served for the whole interwar and for a few, WW2 (many were decommissioned or converted for other uses in 1940, seen as obsolete). They were built at Yokosuka but also Kure, Fujinagata, Ishikawajima, Kawasaki and Uraga.

They were virtually repeats of the cheap and simple Enoki second-class destroyers, comparable in some ways to Royal Navy corvettes. Their main trade feature like German destroyers was a lengthened forecastle with a break forming immediately forward of the bridge giving protection to the forward bank of torpedo tubes. They used three Kampon oil-fired boilers, and light turbines of the Parsons, Brown-Curtis, Escher Wyss & Cie Zoelly, Mitsubishi, but Kampon turbines for most Consequentely these ships developed 21,500 hp (16,000 kW), enough for their 800 tonnes to reach 36 knots. Their career will be seen in detail in ww2 IJN destroyer post, but in short, 11 were lost in action.


Tsuta as converted as a fast landing ship transport in 1943, notice the Daihatsu barge and modified stem.
