SMS (or ) was an ironclad turret ship built for the German (Imperial Navy). She was laid down at the Imperial Dockyard in Wilhelmshaven in 1870 and completed in 1878; her long construction time was in part due to a redesign that was completed after work on the ship had begun. Her main battery of four guns was initially to be placed in a central armored battery, but during the redesign, this was altered to a pair of twin gun turrets amidships.
was sunk on her maiden voyage when she was accidentally rammed by the ironclad . The two ships, along with , were steaming in the English Channel on 31 May 1878. The three ships encountered a group of fishing boats under sail; in turning to avoid them, inadvertently crossed s path and was rammed, sinking within about fifteen minutes. Between 269 and 284 of her crew drowned. Her loss spurred a series of investigations into the circumstances of the collision, which ultimately resulted in the acquittal of both Rear Admiral , the squadron commander, and Count Alexander von Monts, the captain of . Political infighting over the affair led to the ousting of Rear Admiral Reinhold von Werner from the navy.
Design
The three -class ironclads were authorized under the naval program of 1867, which had been approved by the (Imperial Diet) to strengthen the North German Federal Navy in the wake of the Second Schleswig War, when the weak Prussian Navy had been unable to break the blockade imposed by the Danish Navy. Initially ordered as casemate ships, the vessels were re-designed as turret ships; they were the first uniform class of ironclads built for the German fleet.
was long overall and had a beam of and a draft of forward. The ship was powered by one 3-cylinder single-expansion steam engine, which drove a single screw propeller. Steam was supplied by six coal-fired transverse trunk boilers, which were vented into a single funnel. The ship's top speed was , at . She was also equipped with a full ship rig of sails. Her standard complement was 46 officers and 454 enlisted men.
She was armed with a main battery of four L/22 guns mounted in a pair of turrets placed on the centerline amidships. As built, the ship was also equipped with two RK L/25 guns as chase guns, one in the bow and one in the stern. s armor was made of wrought iron backed with teak. The armored belt was arrayed in two strakes. The upper strake was thick; the lower strake ranged in thickness from . Both were backed with of teak. The gun turrets were protected by armor on the sides, backed by 260 mm of teak.
Service history
("Great Elector") was ordered by the Imperial Navy from the (Imperial Dockyard) in Wilhelmshaven; the date of her keel laying is unclear. According to the historian Erich Gröner, work on the ship began in 1869 under construction number 2, but the historians Hans Hildebrand, Albert Röhr, and Hans-Otto Steinmetz state that construction work on the newly built was not completed until December 1869, and that it was not clear whether any work on the ship had begun before the start of the Franco-Prussian War in July 1870 beyond collecting building materials. Furthermore, they state that the specific date has not survived in the available records. The ship's name was originally to have been , but it was changed slightly to during construction.
The ship was launched on 17 September 1875; at the launching ceremony, the Chief of the Imperial Admiralty, General Albrecht von Stosch, christened the ship on behalf of Peter II, Grand Duke of Oldenburg, who had been invited for the ceremony but was ill. Work on the ship was largely completed by December 1877, permitting the beginning of sea trials. She was formally commissioned of 6 May 1878, though she still had shipyard workers aboard. The ship was placed under the command of (Captain at Sea) Alexander von Monts. The lengthy construction period was the result of several factors: the delay caused by the Franco-Prussian War, the inexperience of the new imperial shipyard, and the re-design of the ship after work had begun.
Collision and loss
In April 1878, the armored squadron was reactivated for the annual summer training cycle, under the command of Carl Ferdinand Batsch. Stosch ordered to join the unit, which included her sisters and , the large ironclad , and the aviso after her commissioning on 6 May. She was to join the rest of the unit at 27 May, just three weeks after her crew came aboard the ship and before they were sufficiently familiar with the vessel. Batsch recognized that the crew was not ready for major operation, but he instructed to join him anyway to comply with Stosch's orders. A grounding by caused serious damage to her hull and prevented her from taking part in the upcoming training cruise. The three ships left Wilhelmshaven on the 29th, bound for the Mediterranean Sea.
Shortly after leaving Germany, the squadron parted ways temporarily with due to engine problems aboard the aviso. While crossing the North Sea, briefly had her rudder stuck, but her crew were able to free it while underway. The ship also had trouble keeping station with the other ironclads, in part due to poor quality coal, but also the inexperience of her boiler room personnel, who had trouble keeping pressure up in the boilers. The ships initially traveled in two columns, the left one led by , which was followed by . steamed to their right by herself. At 02:55 on 31 May, the German ships entered the English Channel and temporarily shifted to a single file formation. The ships soon resumed their original formation, with steaming from the other ships. At 07:40, the ships passed the east light ship at Goodwin Sands, and fifty minutes later, entered the Strait of Dover.
Five minutes after entering the Dover strait, Batsch ordered to close to within as the waterway narrowed. Monts took direct command of the helm to comply with Batsch's command. At 09:00, the ships passed the narrowest point in the straits; they steamed at a speed of . Shortly thereafter, while passing Folkestone, the ships encountered a barque and a brig sailing on a southeast course, some from the German vessels. In accordance with maritime regulations, and turned to starboard to avoid a collision with the merchant vessels. conformed with the maneuver, but she and accidentally closed with each other. Monts ordered his ship's engines to full power and turned hard to starboard in an attempt to avoid the flagship, while Batsch ordered hard to port, but neither vessel was able to turn in time. found herself pointed directly at ; her ram bow tore a large hole in s side. The collision was so severe that was pushed back to port and part of her mizzenmast was torn off, among other damage to the upper works of the ship. Most of the ship's boats on the port side were also destroyed.
disentangled from and slowly returned to her original course, and the latter attempted to follow the flagship on the port side. Flooding aboard was quickly brought under control, but the crew aboard was unable to do so. This was in part due to the fact that the damage hole in her hull was at the location of one of her transverse watertight bulkheads. Worse, s remaining watertight bulkheads were not adequately sealed, which also contributed to her rapid sinking. As the ship took on more water and the list increased, water began to enter through open portholes as well. Monts had attempted to steer the fatally damaged ship into shallower water, but was unable to cross the approximate before she capsized and sank. Shortly before sinking, about fifteen minutes after the collision, Monts ordered the crew to abandon ship.
slowly approached and lowered all of her boats to pick up the men in the water, while stopped some away, her captain having decided to strictly follow regulations. Nearby British fishing boats and other vessels also joined the rescue effort. They picked up some sixty men. Monts was picked up by one of 's boats, but it capsized due to overcrowding; he thereafter helped another man stay afloat until they were picked up by another boat. Figures for the number of fatalities vary. Gröner reports that out of a crew of 500 men, 269 died in the accident; Hildebrand, Röhr, and Steinmetz concur with the fatality total, but state that there were only 487 men aboard the ship at the time of the sinking. Lawrence Sondhaus states that 276 men were killed, and Aidan Dodson reports 284 fatalities. Many of the bodies were ultimately buried in Cheriton Road Cemetery, Folkestone, where there is a substantial memorial. Arthur Sullivan, on his way to Paris, witnessed the incident, writing, "I saw it all – saw the unfortunate vessel slowly go over and disappear under the water in clear, bright sunshine, and the water like a calm lake. It was too horrible – and then we saw all the boats moving about picking up the survivors, some so exhausted they had to be lifted on to the ships."
was badly damaged in the collision, with severe flooding forward. s captain initially intended to beach the ship to prevent it from sinking, but determined that the ship's pumps could hold the flooding to an acceptable level. The ship made for Portsmouth, where temporary repairs could be effected to allow the ship to return to Germany. The survivors were carried home to Germany aboard the two ironclads and , which had repaired her engines and arrived in Folkestone by that time. In the aftermath of the collision, the German navy held a court martial for Batsch, the squadron commander, and Captains Monts and Kuehne, the commanders of the two ships, along with Lieutenant Clausa, the first officer aboard , to investigate the sinking.
Inquiry
In the ensuing inquiry, chaired by Reinhold von Werner, Monts testified that he had not been given sufficient time to familiarize himself with the ship and its crew, who were themselves unfamiliar with the vessel. Monts argued that the mobilization process for the newly commissioned ship should have lasted four to six weeks, rather than the three he had been given. The day before the squadron left Wilhelmshaven, Batsch complained to Stosch that a significant number of dockyard workers were still finishing work on . Werner and the board determined that Batsch was at fault and exonerated Monts. Their report was issued on 22 July. Stosch had attempted to interfere in the investigation by blaming Monts to protect Batsch, who was his protege and his preferred successor. Stosch's attempts to manipulate the court martial prompted Kaiser Wilhelm I to issue a reprimand for his conduct.
Stosch was infuriated that the proceedings had been allowed to become a forum for criticism of his policies, for which he blamed Werner. He appealed to Kaiser Wilhelm, stating that the inquiry had unfairly blamed Batsch, and requested a new court-martial for the involved officers. Simultaneously, Stosch began a campaign to force Werner out of the navy. This was in part to ensure that Batsch would be next in line after Stosch retired. Despite his popularity, particularly with Kaiser Wilhelm I and his son, Werner was unable to resist Stosch's efforts to force his ouster. On 15 October 1878, he requested retirement.
