Schleswig-Holstein is the northernmost of the 16 states of Germany, comprising most of the historical Duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg.
Holstein is the region between the rivers Elbe and Eider. It is the southern half of Schleswig-Holstein, the northernmost state of Germany.
Howaldtswerke-Deutsche Werft is a German shipbuilding company, headquartered in Kiel. It is part of the ThyssenKrupp Marine Systems (TKMS) group, owned by ThyssenKrupp. The Howaldtswerke shipyard was founded in Kiel in 1838 and merged with Hamburg-based Deutsche Werft to form Howaldtswerke-Deutsche Werft (HDW) in 1968. The company's shipyard was formerly used by Friedrich Krupp Germaniawerft until the end of World War II.
August Ferdinand Howaldt was a German engineer and ship builder. The German sculptor Georg Ferdinand Howaldt was his brother.
HMS Thetis was a 36-gun fifth-rate frigate of the Royal Navy. After nearly a decade of service with the British, she was transferred to Prussia in exchange for two steam gunboats. She served with the Prussian Navy, the North German Federal Navy and the Imperial German Navy as a training ship until being stricken in 1871. Thetis was subsequently converted into a coal hulk and broken up in 1894–95.
The Altona-Kiel Railway Company was a joint-stock company, established under the law of Denmark in personal union with the Duchy of Holstein, that built and operated an 105 km railway line between Altona and the Baltic Sea port city of Kiel. Altona was at that time the second largest city under Danish rule and the railway line was the first built in Danish-controlled territory.
SMS Meteor was a Camäleon-class gunboat of the North German Federal Navy that was launched in 1865. A small vessel, armed with only three light guns, Meteor took part in the Battle of Havana in 1870 during the Franco-Prussian War. There, she battled the French aviso Bouvet; both vessels were lightly damaged, though Bouvet was compelled to disengage after a shot from Meteor disabled her engine. After the war, Meteor returned to Germany, where her career was limited; she served briefly as a survey vessel. From 1873 to 1877, she was deployed to the Mediterranean Sea as a station ship in Constantinople during a period of tensions in the Ottoman Empire. After returning to Germany in 1877, she was decommissioned, converted into a coal hulk and expended as a target ship some time later.
SMS Comet was a Camäleon-class gunboat of the Prussian Navy that was launched in 1860. A small vessel, armed with only three light guns, Comet served during the Second Schleswig War of 1864 and the Franco-Prussian War of 1870–1871, part of the conflicts that unified Germany. The ship was present at, but was only lightly engaged in the Battle of Jasmund during the Second Schleswig War. She served in a variety of roles during peacetime, including fishery protection and survey work. Comet went on one lengthy deployment abroad, with an assignment to the Mediterranean Sea from 1876 to 1879. She saw little active service after returning to Germany and was decommissioned and hulked in 1881. The vessel remained in the navy's inventory until at least 1891, being broken up sometime thereafter.
SMS Blitz was a Camäleon-class gunboat of the Prussian Navy that was launched in 1862. A small vessel, armed with only three light guns, Blitz served during all three wars of German unification in the 1860s and early 1870s. The ship was present during the Battle of Heligoland in May 1864 during the Second Schleswig War, but was too slow to engage the Danish squadron. During the Austro-Prussian War of 1866, she operated against the Kingdom of Hanover in the North Sea, but did not see extensive action. In August 1870, Blitz and three other light vessels attacked the French blockade force in the Baltic Sea during the Franco-Prussian War, but they withdrew without either side scoring any hits. During her peacetime career, Blitz was sent to the Mediterranean Sea twice, in 1863 and 1867–1868. She was employed as a fisheries protection ship, a guard ship, and a survey vessel in the early 1870s, before being decommissioned in 1875 and broken up for scrap in 1878. Parts of her machinery were reused in the gunboat Wolf.
SMS Basilisk was a Camäleon-class gunboat of the Prussian Navy that was launched in 1862. A small vessel, armed with only three light guns, Basilisk served during all three wars of German unification in the 1860s and early 1870s. The ship was present during the Battle of Heligoland in May 1864 during the Second Schleswig War, but was too slow to engage the Danish squadron. During the Austro-Prussian War of 1866 and the Franco-Prussian War of 1870–1871, Basilisk was stationed in the North Sea to help defend the coast, but she did not see action during either conflict. Between 1873 and 1875, she was employed experimentally as the first torpedo-armed warship of the German fleet. Basilisk was decommissioned in 1875, renamed "Mine Barge No. 1", and converted into a naval mine storage hulk. The details of her fate are unrecorded, but she was still in service in that capacity at least as late as 1900. Sometime thereafter, she was broken up.
SMS Cyclop was a Camäleon-class gunboat of the Prussian Navy that was launched in 1860. A small vessel, armed with only three light guns, Cyclop served during the three wars of German unification; during the first, the Second Schleswig War on 1864, she guarded the Prussian coastline but saw no action. She supported the army's campaign against the Kingdom of Hanover during the Austro-Prussian War of 1866, and she defended the Elbe for the duration of the Franco-Prussian War of 1870–1871, but again took part in no battles. Badly deteriorated by 1872, she was stricken from the naval register in March that year and reconstructed into an iron-hulled gunboat. Recommissioned in 1875, she thereafter served abroad in the German colonial empire before being stricken again in 1888. She was thereafter used as a storage hulk before ultimately being broken up for scrap after 1914.
SMS Camäleon was the lead ship of the Camäleon class of steam-powered gunboats of the Prussian Navy that was launched in 1860. A small vessel, armed with only three light guns, Camäleon saw little active use. She served during the Second Schleswig War of 1864 and the Franco-Prussian War of 1870–1871, but saw no action in either conflict. Her peacetime career was limited to survey work in 1865 and limited tender duties in and around Kiel in 1867–1868. In poor condition by 1872, she was stricken from the naval register and used as a storage hulk in Kiel. She was broken up for scrap some time after 1878.
SMS Delphin was a Camäleon-class gunboat of the Prussian Navy that was launched in 1860. A small vessel, armed with only three light guns, Delphin served during the Second Schleswig War of 1864 and the Austro-Prussian War of 1866, part of the conflicts that unified Germany. The ship was present at, but was only lightly engaged in the Battle of Jasmund during the Second Schleswig War. The ship spent much of the rest of her career in the Mediterranean Sea, going on three lengthy deployments there in 1865–1866, 1867–1870, and 1871–1873. During the last tour, she took part in operations off the coast of Spain with an Anglo-German squadron during the Third Carlist War, where she helped to suppress forces rebelling against the Spanish government. For the rest of the 1870s, she served as a survey vessel in the North and Baltic Seas before being decommissioned in August 1881, stricken from the naval register the following month, and subsequently broken up for scrap.
SMS Drache was a Camäleon-class gunboat of the Prussian Navy that was launched in 1860. Budgetary problems delayed her completion until 1869, and she first entered service during the Franco-Prussian War in 1870, though she saw no significant action against the French Navy. Drache spent most of her career, between 1872 and 1887, conducting survey work in the North Sea, which later proved to be instrumental to the operations of German U-boats and minelayers during World War I. Drache was ultimately decommissioned in 1887, reduced to a coal hulk, and then expended as a target for the torpedo boat D5 in 1889. Her wreck was later raised and broken up.
The Camäleon class was a group of gunboats built for the Prussian Navy. Eight ships comprised the class: Camäleon, Comet, Cyclop, Delphin, Blitz, Basilisk, Meteor, and Drache. The vessels were armed with a battery of one 15 cm (5.9 in) gun and two 12 cm (4.7 in) guns. In 1865, the ships then in service had their 15 cm gun replaced with a 21 cm (8.3 in) gun; Meteor and Drache, not yet completed, entered service with that gun. The vessels saw action during the wars of German unification, with Comet taking part in the Battle of Jasmund and Blitz and Basilisk present during the Battle of Heligoland, both during the Second Schleswig War in 1864. Several of the ships served in the North Sea during the Austro-Prussian War, where some of them supported operations against the Kingdom of Hanover. During the Franco-Prussian War, Meteor battled the French aviso Bouvet in the Battle of Havana in 1870; the other members of the class were deployed on coastal defense assignments.
SMS Nymphe was the lead ship of the Nymphe class of steam corvettes, the first ship of that type to be built for the Prussian Navy. She had one sister ship, Medusa, and the vessels were wooden-hulled ships armed with a battery of sixteen guns. She was ordered as part of a naval expansion program to counter the Danish Navy over the disputed ownership of Schleswig and Holstein. Nymphe was laid down in January 1862, was launched in April 1863, and was completed in October that year.
SMS Preussischer Adler was a paddle steamer originally built in the mid-1840s for use on a packet route between the Kingdom of Prussia and the Russian Empire in the Baltic Sea. She was requisitioned by the Prussian Navy during the First Schleswig War in 1848 and converted into an aviso, the first vessel of the type commissioned by Prussia. During the war, she took part in an inconclusive action with the Danish brig St. Croix, the first naval battle of the Prussian fleet. After the war, she was disarmed and returned to her commercial role, operating uneventfully on the Stettin–St. Petersburg route until 1862, when the expansion of the Prussian Eastern Railway had rendered the maritime route superfluous. The ship was purchased by the Prussian Navy that year and rearmed, once again as an aviso.
SMS Grille was an aviso of the Prussian Navy built in France in the mid-1850s as part of a naval expansion program directed by Prince Adalbert of Prussia, who saw the need for a stronger fleet. She was authorized in 1855 in the aftermath of the First Schleswig War, which had demonstrated the weakness of the Prussian fleet. Grille was the first screw propeller-driven steamship to be built for Prussia; all earlier steam-powered vessels had been paddle steamers.
Edouard Suenson was a Danish vice admiral known for his participation in the First and Second Schleswig War, and served as the main Danish commander at the Battle of Heligoland in the latter.
SMS Gefion was a sailing frigate, originally serving the Danish Navy. In 1849, during the First Schleswig War, she fell into the hands of Schleswig-Holstein under the name of Eckernförde. The ship joined the Reichsflotte in 1850. When it was dissolved in 1852, Prussia bought her for its navy and her old name was restored.
