SMS Hamburg

{{main|Bremen-class cruiser}}

The German 1898 Naval Law called for the replacement of the fleet's older cruising vessels—steam corvettes, unprotected cruisers, and avisos—with modern light cruisers. The first tranche of vessels to fulfill this requirement, the {{sclass|Gazelle|cruiser|4}}, were designed to serve both as fleet scouts and as station ships in Germany's colonial empire. They provided the basis for subsequent designs, beginning with the {{sclass|Bremen|cruiser|4}} that was designed in 1901–1903. The principle improvements consisted of a larger hull that allowed for an additional pair of boilers and a higher top speed.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 2|p=124}}{{sfn|Nottelmann|pp=108–110}}

{{lang|de|Hamburg}} was {{convert|111.1|m|sp=us}} long overall and had a beam of {{convert|13.3|m|abbr=on}} and a draft of {{convert|5.28|m|abbr=on}} forward. She displaced {{convert|3278|t|LT|sp=us|lk=on}} as designed and up to {{cvt|3651|t|LT}} at full 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 274–287 enlisted men.{{sfn|Gröner|pp=102–103}}

Her propulsion system consisted of two triple-expansion steam engines driving a pair of screw propellers. Steam was provided by ten coal-fired Marine-type water-tube boilers, which were vented through three funnels located amidships. Her propulsion system was rated at {{convert|10000|PS|ihp|lk=on}} for a top speed of {{convert|22|kn|lk=in}}. {{lang|de|Hamburg}} carried up to {{cvt|860|t|LT}} of coal, which gave her a range of {{convert|4270|nmi|lk=in}} at {{convert|12|kn}}.{{sfn|Gröner|pp=102–103}}

The ship was armed with a main battery of ten 10.5 cm SK L/40 naval gun in single mounts. Two were placed side by side forward on the forecastle; six were located on the broadside, three on either side; and two were placed side by side aft. The guns could engage targets out to {{convert|12200|m|yd|abbr=on}}. They were supplied with 1,500 rounds of ammunition, for 150 shells per gun. For defense against torpedo boats, she carried ten QF 1-pounder pom-poms in individual mounts. She was also equipped with two {{convert|45|cm|abbr=on|1}} torpedo tubes with five torpedoes. They were submerged in the hull on the broadside.{{sfn|Gröner|pp=102–103}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=59}}

The ship was protected by a curved armored deck that was up to {{convert|80|mm|abbr=on}} thick; it sloped down at the sides to provide a measure of protection against enemy fire. The conning tower had {{convert|100|mm|abbr=on}} thick sides, and the guns were protected by {{cvt|50|mm|0}} thick gun shields.{{sfn|Gröner|p=102}}

{{lang|de|Hamburg}}, ordered under the contract name "K",{{efn|German warships were ordered under provisional names. Additions to the fleet were given a single letter; ships intended to replace older or lost vessels were ordered as "{{lang|de|Ersatz}} (name of the ship to be replaced)".{{sfn|Dodson|pp=8–9}}}} was laid down at the AG Vulcan shipyard in Stettin in August 1902. She was launched of 25 July 1903; at the ceremonies, the First Mayor of Hamburg, Johann Heinrich Burchard christened the ship after the city. A shipyard crew then transferred the unfinished vessel to Kiel for fitting-out. {{lang|de|Hamburg}} was the first member of her class to enter service, being commissioned on 8 March 1904. The naval command intended to send {{lang|de|Hamburg}} as an escort for {{lang|de|Hohenzollern}}, the yacht for Kaiser Wilhelm II, but delays during her sea trials prevented her from joining {{lang|de|Hohenzollern}} until June. She thereafter operated with the yacht for the following three months, beginning with a voyage from Kiel to Hamburg, where Wilhelm II embarked upon {{lang|de|Hohenzollern}} for a sailing regatta. The ships then began a cruise to Norway from 7 July to 9 August; upon the Kaiser's return to Germany, he observed the fleet maneuvers in late August and early September aboard {{lang|de|Hohenzollern}}, with {{lang|de|Hamburg}} accompanying him.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=60}}

Beginning on 28 September, {{lang|de|Hamburg}} joined the Reconnaissance Unit for the main fleet, taking the place of the light cruiser {{SMS|Niobe||2}}. She operated with the fleet that autumn and embarked on a winter training cruise in the Baltic Sea at the end of the year. The ship took part in the peacetime routine of unit and fleet exercises in 1905, interrupted by another voyage in company with Wilhelm II aboard {{lang|de|Hohenzollern}} to Helgoland in March and another to Pillau and Glücksburg in October. She also took part in a cruise with her steam turbine-equipped sister ship {{SMS|Lübeck||2}} to compare the two vessels' propulsion systems. The years 1906 and 1907 passed uneventfully for {{lang|de|Hamburg}}, her time occupied with training exercises with the fleet. During this period, {{lang|de|Fregattenkapitän}} (FK—Frigate Captain) Oskar von Platen-Hallermund served as the ship's commander from September 1906 to the end of September 1907, when he was replaced by {{lang|de|Korvettenkapitän}} (KK—Corvette Captain) Ernst Ritter von Mann und Edler von Tiechler.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=59–60}}

File:SMS Hamburg NH 78288.jpg{{efn|The [https://www.history.navy.mil/content/history/nhhc/our-collections/photography/numerical-list-of-images/nhhc-series/nh-series/NH-78000/NH-78288.html source] of this image states that the photo was taken off San Francisco, though {{lang|de|Hamburg}} never visited the United States, unlike her sister ship {{SMS|Bremen||2}}, which served for nearly ten years in North and South American waters.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 2|pp=124–127}}}}]]

In February 1908, {{lang|de|Hamburg}} embarked on a major training cruise into the Atlantic with the other ships of the Reconnaissance Unit. The vessels steamed as far as Spain, where they visited Vigo. The ship once again escorted {{lang|de|Hohenzollern}} from 6 March to 19 May. During this period, the two ships—along with the dispatch boat {{SMS|Sleipner||2}}—cruised to the Mediterranean Sea. They stopped in Venice, Italy, and the Greek island of Corfu before departing on 5 May to return to Germany. She then returned to fleet duties, which included a major training exercise in the North Sea and a cruise by the entire High Seas Fleet. {{lang|de|Hamburg}} was scheduled to be decommissioned during the winter of 1908–1909, as soon as the new cruiser {{SMS|Dresden|1907|2}} was ready to take her place. But the turbine-powered cruiser proved to have trouble completing her initial testing, which forced {{lang|de|Hamburg}} to remain in service for another year. Another cruise to Spain took place in February 1909, during which time {{lang|de|Hamburg}} again stopped in Vigo from 17 to 23 February.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=60–61}}

Upon returning to German waters, she was again designated the Kaiser's escort for another Mediterranean cruise. {{lang|de|Hamburg}}, {{lang|de|Hohenzollern}}, and {{lang|de|Sleipner}} left Kiel on 24 March and arrived in Venice on 4 April. From there, they moved to Corfu on 16 April, where the Kaiser and his family planned to take their vacation. While there, reports of the persecution of Armenian Christians in the Ottoman Empire prompted widespread reaction throughout Europe; several countries dispatched warships to the southern Anatolian peninsula to protect the Armenians and Europeans in the area. {{lang|de|Hamburg}} was detached as part of the operation and sailed on 21 April to Mersina, arriving there four days later. She was joined by the British battleship {{HMS|Swiftsure|1903|6}} and the French armored cruiser {{ship|French cruiser|Victor Hugo||2}}, and later by {{lang|de|Lübeck}}. The ships sent landing parties ashore to protect civilians, distribute food, and establish field hospitals. The situation had calmed by the mid-May, and on the 17th, {{lang|de|Hamburg}} was detached to return home. She made the voyage, stopping in Port Said, Egypt and Málaga, Spain on the way, and ultimately arriving in Kiel on 28 May.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=61}}

After returning to Germany, {{lang|de|Hamburg}} was assigned to the Reconnaissance Unit. Shortly thereafter, {{lang|de|Hamburg}} was detailed to escort {{lang|de|Hohenzollern}} once again, though this time would be in company with the new armored cruiser {{SMS|Gneisenau||2}}. The ships left Kiel on 13 June and sailed to Neufahrwasser, where Wilhelm II came aboard {{lang|de|Hohenzollern}}. From there, they proceeded into the northern Baltic to Finnish waters, where they met Wilhelm's cousin, Tsar Nicholas of Russia aboard his own yacht. {{lang|de|Hamburg}} returned to Kiel at the conclusion of the trip on 20 June. She continued to operate in company with {{lang|de|Hohenzollern}} for the next month, including during a sailing regatta in early July, the inauguration of the joint German and Swedish passenger ferry service between Sassnitz and Trelleborg. Another summer cruise to Norway followed from 18 July to 3 August, and upon their return to German waters, {{lang|de|Hamburg}} was detached to resume fleet service. She took part in the annual fleet maneuvers in late August and early September for the first time in her career. She was then decommissioned in Wilhelmshaven on 15 September, as by that time, {{lang|de|Dresden}} was finally ready for service.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=62}}

{{lang|de|Hamburg}} spent the years 1910 and 1911 in reserve, during which time she was overhauled but not modernized. She was recommissioned on 2 July 1912 to serve as the second command flagship for I U-boat Flotilla, part of the Torpedo-craft Inspectorate. She arrived at the unit on 6 August and thereafter took part in training exercises in the North Sea, followed by the fleet maneuvers later in August and September. She served in this capacity for the next two years, and during this period, KK Hermann Bauer served as the ship's commander from November 1913 to March 1914. At that time, on 15 March, she was transferred to the newly created U-boat Inspectorate.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=59, 62}}{{sfn|Gröner|p=103}}

Following the outbreak of World War I in July 1914, I U-boat Flotilla was stationed at Helgoland. On 6 August, she and the cruiser {{SMS|Stettin||2}} escorted a flotilla of U-boats into the North Sea in an attempt to draw out the British fleet, which could then be attacked by the U-boats. The force returned to port on 11 August, without having encountered any British warships. Another such operation took place the next day, also without resulting in contact with enemy vessels. On 21 August, the naval command dissolved both I and II U-boat Flotilla and reorganized the vessels of both units under Bauer's command, who was then given the title {{lang|de|Führer der Unterseeboote}} (Leader of Submarines). {{lang|de|Hamburg}} remained the flagship of the unit.{{sfn|Scheer|pp=34–35}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=62–63}}

{{lang|de|Hamburg}} also operated with the High Seas Fleet during this period, generally in company with the light cruisers of IV Scouting Group. The first such operation was the bombardment of Scarborough, Hartlepool and Whitby conducted over the course of 15–16 December. IV Scouting Group was tasked with screening the main element of the fleet while the battlecruisers of I Scouting Group shelled the towns; the intention was to lure out a portion of the British fleet that could be defeated in detail. At 06:59 on 16 December, {{lang|de|Hamburg}}, the armored cruiser {{SMS|Roon||2}}, and the light cruiser {{SMS|Stuttgart||2}} encountered British destroyers under Commander Loftus William Jones. Jones shadowed the Germans until 07:40, at which point {{lang|de|Hamburg}} and {{lang|de|Stuttgart}} were detached to sink their pursuers. Reports of the destroyers prompted Admiral Friedrich von Ingenohl, the German fleet commander, or order the fleet to withdraw. At 08:02, {{lang|de|Roon}} signaled the two light cruisers and ordered them to abandon the pursuit and retreat along with the rest of the High Seas Fleet.{{sfn|Scheer|p=69}}{{sfn|Massie|pp=340–341}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=63}}

The ship continued to operate with the fleet through 1915, in addition to her U-boat flagship duties. While cruising off the mouth of the Weser river on 21 April, she accidentally collided with the torpedo boat {{SMS|S21|1913|2}}, breaking her in half and sinking her. {{lang|de|Hamburg}} had to be drydocked for repairs, though these were completed in time for the ship to participate in a fleet sortie on 17–18 May. Another operation followed on 29–30 May; the ship saw little activity until the fleet conducted another sweep into the North Sea on 11–12 September, by which time the {{lang|de|II. Führer der Torpedoboote}} (2nd Commander of Torpedo Boats), {{lang|de|Kommodore}} (Commodore) Karl von Restorff had hoisted his flag aboard {{lang|de|Hamburg}}. A final operation for 1915 took place on 23–24 October. None of the year's operations had resulted in contact with elements of the British Royal Navy. The fleet continued these operations in 1916, with sorties on 5–7 and 25–26 March and 21–22 and 24–25 April, the last of which resulted in the raid on Yarmouth and Lowestoft.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=63}}{{sfn|Willmott|p=343}}

{{lang|de|Hamburg}} was assigned to IV Scouting Group during the Battle of Jutland on 31 May – 1 June 1916. The IV Scouting Group, under the command of Commodore Ludwig von Reuter, departed Wilhelmshaven at 03:30 on 31 May, along with the rest of the fleet. Tasked with screening for the fleet, {{lang|de|Hamburg}} and the torpedo boat {{SMS|V73||2}} were positioned on the port side of the fleet, abreast of II Battle Squadron. {{lang|de|Hamburg}} and IV Scouting Group were not heavily engaged during the early phases of the battle, but around 21:30, they encountered the British 3rd Light Cruiser Squadron (3rd LCS). Reuter's ships were leading the High Seas Fleet south, away from the deployed Grand Fleet. Due to the long range and poor visibility, only {{lang|de|München}} and {{lang|de|Stettin}} were able to engage the British cruisers. {{lang|de|Hamburg}} only fired one salvo, since the haze rendered it impossible to spot the fall of shot. Reuter turned his ships hard to starboard, in order to draw the British closer to the capital ships of the German fleet, but the 3rd LCS refused to take the bait and disengaged.{{sfn|Tarrant|pp=62, 68, 192–193}}

After a series of night engagements between British cruisers and destroyers and the leading elements of the German fleet, including IV Scouting Group and the battleships of I Battle Squadron, the High Seas Fleet punched through the British light forces and reached Horns Reef by 04:00 on 1 June. In the course of the fighting, {{lang|de|Hamburg}} and the other cruisers bore the brunt of subsequent attacks from British cruisers and destroyers, which scored several damaging hits on {{lang|de|Hamburg}}. The German fleet reached Wilhelmshaven a few hours later; several of the battleships still in fighting condition took up defensive positions outside the port while he rest of the fleet entered Wilhelmshaven. In the course of the battle, {{lang|de|Hamburg}}{{'}}s crew suffered fourteen killed and twenty-five wounded. She was under repair until 26 July.{{sfn|Tarrant|pp=246–247, 263}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=63}}

The German experience at Jutland had demonstrated that older vessels, particularly the pre-dreadnought battleships of II Battle Squadron and cruisers like {{lang|de|Hamburg}} possessed inferior defensive characteristics and were no longer suited to offensive operations. {{lang|de|Hamburg}} also had limited wireless equipment, which hampered her ability to coordinate U-boats while at sea. She participated in her last fleet sortie on 18–20 August, during which Restorff had moved to the dreadnought {{SMS|Prinzregent Luitpold||2}} to use its superior wireless sets. The operation resulted in the action of 19 August 1916, though she was not engaged in the minor battle. {{lang|de|Hamburg}} thereafter served as a headquarters ship for use in port, later being converted into a barracks ship for U-boat crews in Wilhelmshaven. Crew shortages elsewhere in the fleet led her crew to be reduced on 15 March 1917, and from then, KK Friedrich Lützow, who was Restorff's chief of staff, also performed the duties of {{lang|de|Hamburg}}{{'}}s commander.{{sfn|Gröner|p=103}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=63–64}}

In the final weeks of the war, Germany was forced to abandon the U-boat campaign as a requirement for a cease-fire. {{lang|de|Hamburg}} was not interned in Scapa Flow under the terms of the armistice that ended the fighting, and she remained in Wilhelmshaven during the peace negotiations that ultimately produced the Treaty of Versailles. The {{lang|de|Führer der Torpedoboote}} and his staff came aboard the ship in February 1919. Following the signing of the treaty in June 1919, {{lang|de|Hamburg}} was taken into the {{lang|de|Reichsmarinewerft}} in Wilhelmshaven and was decommissioned there on 16 August.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=64}}

{{lang|de|Hamburg}} remained out of service into 1920; instability in Germany during and after the Revolution of 1918–1919 culminated in the Kapp Putsch of March 1920, after which the new German navy, the {{lang|de|Reichsmarine}}, began to recommission the old vessels that it was permitted to retain under the Versailles Treaty. {{lang|de|Hamburg}} was among those vessels, and she was recommissioned on 7 September under the command of FK Bernhard Bobsien. She was assigned to the {{lang|de|Marinestation der Nordsee}} (North Sea Naval Station), becoming the flagship of {{lang|de|Konteradmiral}} (KAdm—Rear Admiral) Friedrich Richter, who fell ill in November and was temporarily replaced by {{lang|de|Kapitän zur See}} (KzS—Captain at Sea) Walter Hildebrand. In addition to serving as the commander of the {{lang|de|Marinestation}}, Richter, and then Hildebrand, was also the commander of II, IV, and VI Flotillas, which were tasked with clearing the minefields that had been laid in the North Sea during the war. KAdm Konrad Mommsen took command of the units on 2 April 1921, keeping {{lang|de|Hamburg}} as the flagship. The cruiser visited the Shetland Islands from 13 to 17 June, the first time since the end of the war that a German vessel visited a foreign port.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=60, 64–65}}

In July 1921, {{lang|de|Hamburg}} took part in fleet training exercises with the battleship {{SMS|Hannover||2}} and the light cruiser {{SMS|Medusa||2}}, along with I and II Flotillas. She escorted minesweepers from the 8th and 11th Minesweeper Half-Flotillas as they cleared a field that had been laid by the auxiliary cruiser {{SMS|Meteor|1914|2}} during the war. While in Kola Bay, the German unit came under fire from a Soviet coastal battery; the Germans returned fire and withdrew. Once the mine-clearing work was completed, the ships returned to Germany, stopping in several Norwegian ports, including Vardø, Hammerfest, Tromsø, Ålesund, and Bergen. They arrived back in Wilhelmshaven on 31 August; {{lang|de|Hamburg}} saw no further activity of note during the year. In February 1922, the ship was employed as an auxiliary icebreaker in the Baltic to assist merchant vessels in the area. Her hull was not strong enough for the task, and she had to be drydocked to repair damage sustained at the end of February. While the work was being done, the battleship {{SMS|Braunschweig||2}} returned to service, replacing {{lang|de|Hamburg}} as the flagship of the {{lang|de|Marinestation}} on 1 March. The rest of the year passed fairly uneventfully, with the only notable occurrences being a visit to Odda, Norway and the annual fleet maneuvers in August and September. After the maneuvers, FK Erich Heyden replaced Bobsien.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=60, 65}}

In July 1923, {{lang|de|Hamburg}} visited Hanko, Finland, and Rønne on the Danish island of Bornholm. Continued unrest in Weimar Germany necessitated the deployment of {{lang|de|Hamburg}} and two torpedo boats to the cruiser's namesake city in October. The two torpedo boats were detached to the Harburg district of the city and {{lang|de|Hamburg}} sent a landing party ashore to help the city's police restore order. During this period, the fleet was reorganized, effective on 15 October; the position of {{lang|de|Oberbefehlshaber der Seestreitkräfte}} (High Command of Naval Forces) was created as the superior command of the two {{lang|de|Marinestation}}. {{lang|de|Hamburg}} served as the flagship of KzS Adolf Pfeiffer, the commander of light naval forces in the North Sea. She spent the year 1924 conducting the normal peacetime routine of training exercises, interrupted by a visit to Riga from 8 to 14 July. After the August–September maneuvers, Heyden was relieved by now-KzS Lützow and Pfeiffer was replaced by KAdm Erich Raeder, though he remained in the position aboard {{lang|de|Hamburg}} briefly, before {{lang|de|Kommodore}} Franz Wieting replaced him in January 1925. At the same time, {{lang|de|Hamburg}} was transferred to the {{lang|de|Marinestation der Ostsee}} (Baltic Sea Naval Station), based in Kiel. Wieting remained the commander of light forces in the North Sea until 1 April, when that position was amalgamated with the deputy commander the battleship division; he thereafter transferred to {{lang|de|Hannover}} in that role. In May, KzS Ernst Junkermann took command of the ship, though he served as the captain for just two months before being replaced by KzS Paul Wülfing von Ditten, who was in turn also relieved after two months by KK Hermann Densch.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=60, 65}}

The ship was transferred to the Training Inspectorate to be used as a training ship, under the command of FK Otto Groos. Preparations began for a major training cruise that would circumnavigate the Earth; Carl Wilhelm Petersen, the mayor of Hamburg, presented the city's flag to the cruiser during ceremonies on 14 February 1926. Petersen then embarked on the cruiser, which took him to Cuxhaven, further downstream on the Elbe. From there, {{lang|de|Hamburg}} passed through the English Channel into the Atlantic; as she steamed south, she made port calls in Pontevedra, Spain, Funchal, Portugal, and Las Palmas in the Canary Islands. From the central Atlantic, she crossed to the West Indies and passed through the Panama Canal and visited the west coast of North and Central America, cruising as far north as San Francisco, United States. She then began her voyage across the Pacific Ocean, stopping in Honolulu in the Territory of Hawaii, on her way to Japan. {{lang|de|Hamburg}} then steamed south to the Philippines, where she visited Manila and Iloilo City, and the Dutch East Indies, where she visited a number of ports. After crossing the Indian Ocean, she stopped in Colombo, British Ceylon, and entered the Red Sea, thereafter passing through the Suez Canal into the Mediterranean. After stopping in Vigo, the last foreign port the ship visited on the trip, she arrived back in Wilhelmshaven on 20 February 1927.{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|pp=60, 65–66}}

{{lang|de|Hamburg}} was decommissioned on 30 June 1927 and she was reduced to reserve status the following year. She was stricken from the naval register on 31 March 1931, and five years later was converted by the {{lang|de|Kriegsmarine}} into a barracks ship for submarine crews starting in 1936. During this period, she was based in Kiel, and she served in this capacity until 1944, when the {{lang|de|Kriegsmarine}} decided to break her up for scrap. She was towed to her namesake city on 7 July 1944 for dismantling,{{sfn|Gröner|p=103}}{{sfn|Hildebrand, Röhr, & Steinmetz Vol. 4|p=66}} where she was later sunk by British bombers on 27 July.{{sfn|Rohwer|p=264}} The wreck was raised in 1949 and ultimately broken up between then and 1956.{{sfn|Dodson & Cant|p=106}}
