Battle of Moon Sound

The Battle of Moon Sound was a naval battle fought between the forces of the German Empire, and the then Russian Republic (and three British submarines) in the Baltic Sea from 16 October 1917 until 3 November 1917[1] during World War I. The German intention was to destroy the Russian forces and occupy the West Estonian Archipelago. The Imperial German Navy had 1 battlecruiser, 10 battleships, 9 light cruisers, 1 mine cruiser, 50 destroyers and 6 submarines while the Russians had only 2 pre-dreadnoughts, 3 cruisers, 3 gunboats, 21 destroyers, plus 3 British submarines.[2]

Background

It was the Germans' intention to destroy the Russian Army and occupy the West Estonian Archipelago (Moonsund Archipelago). The Germans captured the archipelago, with its main islands of Saaremaa (Ösel), Hiiumaa (Dagö), and Muhu (Moon) during Operation Albion in September 1917. This left a Russian squadron consisting of the old Russo-Japanese War-era pre-dreadnought battleships Grazhdanin (Tsesarevich), and Slava, together with cruisers and destroyers, stranded in the Gulf of Riga. Following the battle, the squadron escaped on 17 October 1917 by way of the Suur Strait separating the island of Muhu from the Estonian mainland. It was thought in the west at the time that the Russian naval force could have been stronger if newer and larger ships had been sent from Petrograd and that indiscipline in the Navy had prevented this. This was reported in the London newspaper The Times soon afterwards.[3]

Many of the sailors fighting for Russia organised themselves democratically and in the preceding months these organisations had passed numerous motions denouncing the war and calling for an immediate peace. Nevertheless they also did not want Petrograd, as the centre of the revolution, to fall into the hands of the German military. Many suspected that sections of the government, which would soon be overthrown in the October Revolution, now wanted to abandon Petrograd so the revolution could be pacified. This train of thought can be seen in the radio message that many of the Russian ships broadcast during the battle; "Attacked by superior German forces our fleet will go down in unequal battle. Not one of our ships will decline the fight. The slandered and maligned fleet will do its duty...but not at the command of a miserable Russian Bonaparte, ruling by the long suffering patience of the revolution...not in the name of the treaties of our rulers with the Allies, binding in chains the hands of Russian freedom...In the hour when the waves of the Baltic are stained with the blood of our brothers...we raise our voice:...Oppressed people of the whole world! Lift the banner of revolt!" [4]

Battle

At the start of the Battle of Moon Sound, there were two British submarines in the Gulf of Riga. They were C 27 (Lt. Sealy) and C 32 (Lt. Satow). When the Germans got there, Captain Francis Cromie sent out another submarine called C 26 (Lt. Downie). On the night of 16 October, Lt. Sealy fired two torpedoes at two German ships but missed. Two further torpedoes struck their targets. C 27 returned to Hanko when it was no longer needed. C 32 attempted to attack a German ship but was spotted and bombed. In the afternoon of 16 October, Gruppe Behncke travelled to the south exit of the Suur Strait and dropped anchor around 8:30 pm. All German ships were anchored in a close line with a torpedo boat at each end. The Germans made significant progress on shore on 16 October, taking 120 officers and 400 men prisoner and capturing 49 guns. By the end of the day, German forces were prepared to capture the West Estonian Archipelago and the navy was ready to attack in the Matsalu Bay and the Suur Strait.[5]

The Russian battle strategy was changed at 4:30 am on 17 October due to a mistake made in the transfer of an order. That morning, ships were on the move by 7:00. The 3rd M.S.H.F was heading east while the 8th H.f.F.l. was heading north under command of Erich Koellner.[5]

At 7:20, Russian battleships opened fire on the 8th H.f.F.l, the 3rd M.S. Dive and the Sperrbrecher. The 8th advanced but were under constant Russian fire. It was the 3rd M.S.H.F's duty to clear mines.[5]

At 8:00 am Admiral Behncke ordered that the cruisers not advance any further. At this point, König and Kronprinz proceeded east by the 3rd M.S.H.F, both under the command of Georg von der Marwitz. Slava was advancing so that she came between Paternoster and Werder and started firing upon any east-bound German ship. While this was going on, the 3rd M.S.H.F. had reached Laura Bank and turned north, König and Kronprinz continued east and Slava was now heading north. Admiral Hopman was at the same time heading west towards the Väike Strait.[5]

At 9:10, two Russian ships that had returned south opened fire on the 3rd M.S.H.F. The Russians now understood that if they could stop the minesweepers, they could stop the entire German attack. At 9:40, 3rd Ms. Dive was brought over to the east side of Russian minefields to assist the 3rd H.f.F.l.[5]

By 10:00, the minesweepers were on the northern edge of the rectangular minefield. König and Kronprinz now went forward. Around 10:13, König opened fire on Slava. By 10:17, Kronprinz followed König`s lead and opened fire on the battleship Grazhdanin. Bayan was also attacked by König. Slava took many underwater hits, causing extensive damage. Grazhdanin only got hit twice in all of the chaos. At 10:40 the Germans ceased fire. The Russians continued to fire on the 3rd M.S.H.F. Around 10:30, Admiral Bachirev ordered all sea forces to withdraw to the northern Suur Strait. Slava, now fatally wounded, was scuttled by Turkmerec Strauropolski.[5] The Russians were determined to make the channel impossible to pass through so they laid out more mines and used damaged ships to their advantage. At 10:46, the Werder Battery opened fire on the German battleships.[5]

At approximately 11:09, two German battleships anchored while under fire at Võilaid. At 11.28 there was a false submarine alarm followed by a legitimate one at 12:08.[5]

Around 1:35, Kolberg attacked Võilaid for approximately ten minutes but met no reply. At 3:45, Admiral Hopman`s flagleutnant Obltz Keln led a landing party to take over Woi. At 5:30, white star shell could be seen which meant that the battery had successfully been taken but the guns were unserviceable. By 3:00, Kommodore Heinrich took V100 toward the channel that would lead them to the Suur Strait but were immediately under fire by gunboats under the control of Admiral Makarov.[5]

At 10:00pm, Kptlt Zander began to go forward to the Suur Strait. The V25-class torpedo boat S 50 took up position to mark the passage. At the end of the day, Germans were in control over the southern Suur Strait, the Väike Strait and the Matsalu Bay. On the night of 17 October, Russians gave up trying to capture the Suur Strait. Just after midnight on 18 October, V25-class torpedo boat S 64 hit a mine and was rendered unmanoeuvrable.[5] She sank before 1 a.m. At dawn, German torpedo boats assumed patrol stations in the Matsalu Bay. The landing operations on Hiiumaa gained momentum between 7:15 and 8:00 am, and the area around Emmaste was secured. By 8:30, German minesweepers had worked forward to a mile south of the Viirelaid lighthouse. At 8:00, Behncke's group started east and went behind the 3rd M.S.H.F.[5]

Just after 10:00, Behncke ordered Admiral Hopman to dispatch Strassburg and the 8th M.S.H.F. to the 3rd squadron while Kolberg, the torpedo-boats and Sperrbrecher would remain to the west. At 12:40 the 3rd M.S.H.F. and two boats of the half flotilla confirmed that Slava was sunk along with two freight steamers. The Germans could see Russian destroyers laying mines, the Russians had not yet detected the Germans, so the Germans opened fire, which was met with a reply. Two German torpedo boats opened fire as the Germans continued northward, two Russian gunboats and several destroyers took them under fire. They then turned south at high speed under the cover of a smoke screen. By the evening of the 18th, Kuressaare had been made a supply base, the southern part of Hiiumaa under control of the second Cyclist Battalion and the S-Flotilla landing section, Saaremaa and Muhu were now firmly in German hands.[5]

On 19 October the forces of the Gulf of Riga and numerous transport steamers and auxiliaries left the northern Suur Strait under the protection of minesweepers and destroyers. By mid-afternoon, the German forces had penetrated the strait. The German losses were seven minesweepers, nine trawlers and small boats as well as one torpedo-boat. The Imperial Navy had a total of 156 dead and 60 wounded. The army had 54 dead and 141 wounded. The German Army captured 20,130 prisoners, 141 Russian guns including 47 heavy pieces and 130 machine guns.[5]

Aftermath

The loss of the Moon-sund archipelago was used by the Provisional Government as a pretext to begin preparations to move the capital from Petrograd to Moscow. The Bolsheviks accused the Provisional Government of refusing to defend the revolutionary capital and attempting to abandon it to imperialist forces. Pressure from below forced the government to abandon these plans.[6]


The German destroyer S 64, and the Russian destroyer Grom were both sunk. Of the Russian heavy ships Citizen was damaged, with Slava so badly damaged that it was scuttled. The German battleships Bayern and Grosser Kurfürst were both damaged by mines (restored fully to service by December), and SMS Kronprinz was also slightly damaged by a grounding but not requiring docking. The German B 97-class destroyer B 98 was damaged, A 32 ran aground (refloated), the auxiliary ship Corsika slightly damaged, 7 minesweepers were sunk in anti-mine operations.
