SMS Ariadne

before the war

SMS was the fifth member of the ten-ship of light cruisers that were built for the German (Imperial Navy) in the late 1890s and early 1900s. The class was the culmination of earlier unprotected cruiser and aviso designs, combining the best aspects of both types in what became the progenitor of all future light cruisers of the Imperial fleet. Built to be able to serve with the main German fleet and as a colonial cruiser, she was armed with a battery of ten [[10.5 cm SK L/40 naval gun|Template:Cvt guns]] and a top speed of .

saw little service during her career; she served with the main fleet, first in I Squadron and then with I Scouting Group between 1902 and 1906. During this period, she took part in routine training exercises and cruises abroad. Decommissioned in late 1906, she lay in reserve until the start of World War I in July 1914. Reactivated on 2 August, she served as a flotilla leader for torpedo boats guarding Germany's North Sea coast. During the Battle of Helgoland Bight on 28 August, she sortied to reinforce the ships on patrol in the Helgoland Bight, where she was surprised and sunk by British battlecruisers. Casualty figures vary, with 59 or around 250 of her crew being rescued by other German cruisers.

Design

Following the construction of the unprotected cruisers of the and the aviso for the German (Imperial Navy), the Construction Department of the (Imperial Navy Office) prepared a design for a new small cruiser that combined the best attributes of both types of vessels. The designers had to design a small cruiser with armor protection that had an optimal combination of speed, armament, and stability necessary for fleet operations, along with the endurance to operate on foreign stations in the German colonial empire. The resulting design provided the basis for all of the light cruisers built by the German fleet to the last official designs prepared in 1914.

was long overall and had a beam of and a draft of forward. She displaced Template:Cvt normally and up to at full combat load. The ship had a minimal superstructure, which consisted of a small conning tower and bridge structure. Her hull had a raised forecastle and quarterdeck, along with a pronounced ram bow. She was fitted with two pole masts. She had a crew of 14 officers and 243 enlisted men.

Her propulsion system consisted of two triple-expansion steam engines driving a pair of screw propellers. The engines were powered by nine coal-fired Marine-type water-tube boilers that were vented through a pair of funnels. They were designed to give , for a top speed of . carried Template:Cvt of coal, which gave her a range of at .

The ship was armed with ten [[10.5 cm SK L/40 naval gun|Template:Cvt SK L/40 guns]] in single pivot mounts. Two were placed side by side forward on the forecastle; six were located on the broadside in sponsons; and two were placed side by side aft. The guns could engage targets out to . They were supplied with 1,000 rounds of ammunition, for 100 shells per gun. She was also equipped with two torpedo tubes with five torpedoes. They were submerged in the hull on the broadside.

The ship was protected by an armored deck that was thick. The deck sloped downward at the sides of the ship to provide a measure of protection against incoming fire. The conning tower had thick sides, and the guns were protected by Template:Cvt thick gun shields.

Service history

One of the -class cruisers, possibly , in Kiel in 1901

was ordered under the contract name "D",Template:Efn and was laid down at the AG Weser shipyard in Bremen on 14 December 1899. She was launched on 10 August 1900 and the director of the (Imperial Shipyard) in Wilhelmshaven, (KAdm—Rear Admiral) Hugo von Schuckmann gave a speech at the ceremony, after which fitting-out work commenced. She was commissioned for sea trials on 18 May 1901. While on trials on 11 July, her first port side boiler exploded; three were killed and another three were injured in the accident. The ship was finally pronounced ready for service on 22 October 1902, when she was assigned to I Squadron, based in Kiel. (KK—Corvette Captain) Adolf Josephi took command of the ship at that time. She joined the battleships of the squadron for a cruise to Norway, followed by training exercises in the North Sea. On 1 March 1903, was assigned to I Scouting Group, the fleet's primary reconnaissance unit, commanded by KAdm Ludwig Borckenhagen.

The unit embarked on a training cruise to Spain in early 1903, during which stopped in Brest, France on 14 May to pick up mail for the squadron. In July, the bulk of the fleet, including , made another visit to Norwegian waters. The fleet's annual autumn training maneuvers were held in September and October, taking place in both the North and Baltic Seas. The ship took part in fleet exercises in May 1904, followed by a naval review for British King Edward VII during his visit to Kiel. The fleet then made a visit to Britain, and later escorted Kaiser Wilhelm II's yacht on a cruise from 3 to 10 September. KK Johannes Schirmer replaced Josephi at that time. In 1905, the ship took part in the year's program of training exercises, which were interrupted in March when the battleship ran aground in the Great Belt; was among the vessels sent to pull her free. In February 1906, escorted the new battleship , which represented Germany at the coronation ceremonies for the Danish King Frederik VIII in Copenhagen. After returning to Germany, was decommissioned in Wilhelmshaven on 22 September and placed in reserve, where she remained for the next eight years.

Actions of at the Battle of Helgoland Bight

After the outbreak of World War I in July 1914, was recommissioned on 2 August for use as a flotilla leader for the coastal defense torpedo boat flotillas that guarded the mouths of the Jade and Weser rivers. The ships were tasked with protecting these important waterways from attacks by enemy warships. Her commander was (Captain at Sea) Hans Seebohm.

On 23 August, several British commanders submitted a plan to attack the patrol line along the German coast with the light cruisers and destroyers of the Harwich Force, commanded by Commodore Reginald Tyrwhitt. These ships would be supported by submarines and Vice Admiral David Beatty's battlecruisers and associated light forces. The plan was approved and set for 28 August. The British forces began to leave port on the evening of 26 August, beginning with the submarines assigned to the operation. Most of the surface forces went to sea early on the following morning; the 7th Cruiser Squadron, which had been added to provide further support to the Harwich Force, left port later in the day.

On the morning of 28 August, had been rotated out of the front patrol line and laid at anchor in the entrance of the Weser River in support of the cruisers and torpedo boats on patrol. After receiving reports of the British attack on the morning of the 28th, and several other cruisers got up steam and rushed to support the German patrols. She met in heavy fog at around 13:40, but less than twenty minutes thereafter, Beatty's battlecruisers, chasing , arrived and began firing on as well. She turned to starboard and attempted to flee. She was hit several times by the British guns, and one hit the forward boiler room. The coal bunker caught fire and five boilers were disabled; her speed fell to . Two battlecruisers closed in, one of which was , until they were firing their and guns at a distance of , point-blank range for guns of that caliber. returned fire as best she could, but to no effect.

With fires raging forward and aft, had her forward magazine flooded so the flames would not reach the propellant charges. At 14:15, the British ceased fire and allowed to limp away. The surviving crew that was able to escape the ship assembled on the forecastle and prepared to abandon the ship. The cruiser arrived shortly before 15:00 and began to pick up survivors, with and joining the rescue effort shortly thereafter. attempted to take the crippled vessel under tow, but at 16:25, capsized, mooting the effort to save the ship. She remained afloat for some time before she finally sank. The rescue effort was hampered by frequent explosions of ammunition stored on Template:'s deck, which prevented boats from getting too close to the wrecked cruiser. Reports of casualties differ widely. According to the historian Gary Staff, a total of nine officers, including her commander, and fifty enlisted men were rescued. But the historians Hans Hildebrand, Albert Röhr, and Hans-Otto Steinmetz state that some 250 of her crew were rescued, with only 64 of her crew being killed in the sinking.

The wreck was discovered in 1973; it lies at a depth of about Template:Cvt to the north of the island of Norderney at the coordinates 54°09′N 7°7′E. came to rest around from the location where she was reported to have sunk.
