Dresden-class cruiser

SMS transiting the Kaiser Wilhelm Canal

The class was a pair of light cruisers built for the Imperial German Navy in the early part of the 20th century. The class comprised , the lead ship, and . Both ships were laid down in 1906; was launched in 1907, and followed in 1908. They entered service in 1908 and 1909, respectively. The design for the ships was an incremental improvement over the preceding , being slightly larger and slightly faster, but with the same primary armament of ten guns. and were powered by steam turbines and triple expansion engines, respectively, as part of continued experiments with the new turbine technology.

Both ships served extensively on foreign stations; was assigned to the East Asia Squadron from her commissioning, and was sent to Caribbean waters in 1913. was due to return to Germany for periodic maintenance shortly before the outbreak of World War I in August 1914, but this became impossible with the onset of hostilities. She therefore operated as a commerce raider, before linking up with Maximilian von Spee's East Asia Squadron. thereafter participated in the Battle of Coronel in November 1914 and the Battle of the Falkland Islands the following December. She was the only German vessel to escape destruction at the latter engagement, and she remained at large for several more months. finally put into the Chilean island of Más a Tierra in March 1915 owing to worn-out engines. A pair of British cruisers violated Chilean neutrality and attacked while she lay at anchor; the Germans scuttled their ship to prevent her capture.

, meanwhile, had been detached from the East Asia Squadron to pursue an independent commerce raiding campaign in the Indian Ocean. She captured or sank numerous Entente vessels, including the steamer Ryazan which was converted into the auxiliary cruiser . In September 1914, raided Penang and caught the Russian protected cruiser and the French destroyer and quickly destroyed both ships. Shortly thereafter, was caught by the Australian cruiser off the Cocos Islands and forced to beach after a ferocious engagement.

Design

The 1898 Naval Law authorized the construction of thirty new light cruisers; the program began with the , which was developed into the and es, both of which incorporated incremental improvements over the course of construction. The two ships of the class were ordered in the 1905–1906 construction program. Their design represented an incremental improvement over the earlier class. They carried the same main battery of guns on a slightly greater displacement with an additional boiler for the propulsion system to increase engine power. Like the s, one ship——was fitted with a steam turbine engine to compare its performance with the traditional triple-expansion engine in an otherwise-identical sister ship. All subsequent designs of German cruisers utilized turbine propulsion systems.Template:SfnTemplate:SfnTemplate:Sfn

General characteristics and machinery

The two -class cruisers were long at the waterline and long overall. They had a beam of and a draft of forward. They displaced as designed and up to at full load. Their hulls were constructed with transverse and longitudinal steel frames. The hulls contained thirteen watertight compartments and had a double bottom that extended for 47 percent of the length of the keel.Template:Sfn

The ships were good sea boats, but they were crank and rolled up to twenty degrees. They were also very wet at high speeds and suffered from a slight weather helm. Nevertheless, the ships turned tightly and were very maneuverable. In a hard turn, their speed fell up to 35 percent. They had a transverse metacentric height of . and had a crew of 18 officers and 343 enlisted men. They carried a number of smaller boats, including one picket boat, one barge, one cutter, two yawls, and two dinghies.Template:Sfn

Template:'s propulsion system consisted of two sets of Parsons steam turbines, designed to give . , instead, was equipped with two triple expansion engines rated at . Both ships had a top speed of . In both vessels, the engines were powered by twelve coal-fired Marine-type water-tube boilers. Both ships carried up to of coal, though their ranges were slightly different, owing to their different propulsion systems. could steam for at , while had a range of at . Electrical power was supplied by three turbo generators that provided a total of 125 kilowatts at 110 volts.Template:Sfn

Armament and armor

The ships were armed with ten [[10.5 cm SK L/40 naval gun|Template:Cvt SK L/40 guns]] in single pedestal mounts. Two were placed side by side forward on the forecastle, six were located amidships, three on either side, and two were side by side aft. The guns had a maximum elevation of 30 degrees, which allowed them to engage targets out to .Template:Sfn They were supplied with 1,500 rounds of ammunition, for 150 shells per gun. The ships were also equipped with eight [[5.2 cm SK L/55 naval gun|Template:Cvt SK L/55]] guns with 4,000 rounds of ammunition. Both ships were also equipped with a pair of Template:Cvt torpedo tubes with five torpedoes submerged in the hull on the broadside.Template:Sfn

The ships were protected by an armored deck that was up to thick amidships with Template:Cvt thick sloping armor on the sides. The deck was reduced to further aft and then again to toward the stern. The conning tower had thick sides, and the guns were protected by 50 mm thick shields.Template:Sfn

spent most of her career on foreign stations. After her commissioning, she visited the United States in 1909 as part of Germany's delegation to the Hudson–Fulton Celebration.Template:Sfn She returned to North American waters in late 1913, when she was stationed off the Mexican coast to protect German nationals during the Mexican Revolution.Template:Sfn Following the rebels' victory the following year, evacuated the former dictator Victoriano Huerta to Jamaica, where the British had granted him asylum. In need of repairs, the cruiser was scheduled to return to Germany in July 1914, but the outbreak of World War I prevented this from taking place.Template:Sfn Instead, operated as a commerce raider in South American waters in the Atlantic in the first months of the war before moving to the Pacific Ocean in September and thereafter joining Maximilian von Spee's East Asia Squadron.Template:Sfn

Her engines were worn out and she had almost no coal left for her boilers; the ship's captain contacted the local Chilean authorities to have his vessel interned for the duration of the conflict. There, she was trapped by British cruisers, including her old opponent Glasgow; the British violated Chilean neutrality and opened fire on the ship.Template:Sfn The Germans scuttled and the majority of the crew escaped to be interned in Chile for the duration of the war.Template:SfnTemplate:Sfn The wreck remains in the harbor and was first surveyed in 2002.Template:Sfn

Following her commissioning into the fleet, was assigned to the East Asia Squadron. In 1913, (Corvette Captain) Karl von Müller became the ship's commander. At the outbreak of war, was the only major German warship in Qingdao, the main German naval base in Asia. Müller immediately began to operate as a commerce raider, and captured one ship, the Russian steamer Ryazan. was thereafter ordered to rendezvous with the rest of Spee's cruisers. She remained with the East Asia Squadron for only a few days, as Müller convinced Spee to detach as an independent raider in the Indian Ocean.Template:Sfn

After arriving in the Indian Ocean in September, captured several British merchantmen along the sea lanes from India to Aden. On 22 September, the ship bombarded Madras, before resuming the hunt for merchant ships. She captured several more vessels, and then raided the port of Penang. There, caught the Russian protected cruiser in the harbor and quickly destroyed her. As was departing, she encountered and sank the French destroyer . thereafter proceeded to the Cocos Islands, where Müller intended to destroy a wireless station. The Australian cruiser reacted to British wireless signals warning of the Germans' presence. After a fierce gunnery duel, Sydney caused serious damage to and forced her to beach on North Keeling island. Most of her surviving crew, including Müller, were thereafter taken into captivity.Template:Sfn The wreck was eventually broken up in situ in the early 1950s by a Japanese salvage company, though parts of the ship remain scattered around the area.Template:Sfn
