War-Zones of the S-Boats
English Channel and Northsea 1945
At the beginning of year 1945 F.d.S. had only 31 S-boats available at the western front of which 10 were not ready for batlle (aKB).
The 5. SFltl with "S 48", "S 67", "S 85", "S 92", "S 98", "S 110" and "S 127" was prepared for the employment at the western front at Wilhelmshaven, "S 132" was aKB at Cuxhaven.
Of the 10. SFltl hed up to then only "S 191" arrived at Amsterdam, "S 186" was aKB at Wilhelmshaven after a grounding. Boats "S 215" and "S 224" were still at the Erprobungskommando in the Baltic.
The beginning of the year 1945 was dominated by bad weather, so that the boats did not leave harbour. An attempt to sail for a torpedo-action of the 4., 6. and 9. SFltl on 05.10.1945 had to be broken off, an other attempt of th 4., 6., 8., and 9. SFltl with 24 boats on 09.01.1945 as well.
On 09.01.1945 "S 116" run on ground in the Elbe estuary and was damaged so much, that she was decommissioned and layed up at Lürssen--Shipyard surviving the end of war. It was not turned over to the Allies but taeken over by Schiffsicherungslehrgruppe of the Bundesmarine on 13.06.1957 as trainings-hulk.
The 5. SFltl had arrived at Den Helder with six boats on 10.01.1945.
For the night 14./15.01.1945 a common minelaying operation of the 2. and the 5. SFltl was planned. The 5. SFltl with "S 98", "S 67", "S 127 "S 48", "S 92" and "S 87" had left harbour in the evening with mines. "S 98" and "S67" had to be dismissed due to enginetrouble. The other boats laid four UMB and 15 LMB on the convoy-route notheast of Cromer. (see Minelayingsketch below).

At the same time was the 2. SFltl with "S 221", "S 176", "S 210", "S 180", "S 174" "S 209", "S 181" and "S 177" at sea with mines. "S 221", "S 180", "S 181" and "S 177" had to turn around because of engine trouble. The remaining four boats laid 6 LMB and 8 UMB on the convoy-route off Cromer. "S 209" lost contact to the flotilla because of jamming of two mines, laid her mines and returned to Den Helder alone. On this barrier sank on the same day the freighter "Dalemore" (5835 BRT). On the 19.01. reported the recconnaissance group that on the barrier a steamship and the freighter "Grainton" (6341 BRT) were sunk. As dammaged were reportet: The tanker "San Nicolas" and the freighters "Empire Milner", "Leaside Park" and "Carrier". In reality only the Norwegian freighter "Carrier" (3036 BRT) sank. "Leaside Park" and "Empire Milner" had rammed the wreck of "Dalemore" but could enter Hull with slight damages.
The German boats had been detected ba a recconnaissanvce aircraft and a group of Coastal Forces left Yarmouth. At 01 o'clock radarstation Trimingto detected the boats, the destroyer escort "Middleton" directed to them pursued an own tug which sailed around in the area. When a Lancaster-bomber crashed into the radartower of station Bard Hill this lost contact just having established it.
The boats of the 2. and the 5. SFltl laid mines on the convoi-route off Cromer. When returning "S 180" (OLt zS Albrecht Pillet) run into a German mine. The torpedoes exploded and the boat sank. The commanding officer and SKad. Hermann Trulsen, StrmMt. Bernhard Kolthoff, FkObGefr. Friedrich Braun, Gefr. Brenner, MaschGefr. Leonard Armbichler, and five other men were killed in action. Three wounded and nine unharmed men could be rescued.
During the night 15./16.01.1945 a torpedo operation was conducted with different attack points in the Thames estuary and off Zeebrügge.The 8. SFltl succeeded to torpedo the landing ship tank "LST 415" off the Thames estuary. The boats returned undamaged.
The next evening the 2. SFltl with "S 221", "S 174", "S 209" and "S 181" and the 5. SFltl with "S 98", "S 67", "S 92" and "S 48" were at sea fot a torpedo-operation against a northbound convoy north of Cromer. The convoy was not found and the boats came into a fight with destroyer escort "Farndale". The boats come back to Den Helder unharmed in the early morning.
The 8. SFltl with "S 194", " 196",m "S 197", "S 199" and "S 701" was at sea also and was detected just after leaving harbour and attacked with bombs. Close to Fort Sand Tangues teh boats fired eight FAT and LUT on a convoy. The British tanklandingship "LST 415" (1625 ts) was hit and had to be sat on the beach. A fight with the sloop was overcome without damages.
Bad weather prevented every operation of the boats until 20.01.1945. Not earlier than during the night 22./23.01.1945 the 4., 6., 8., and 9. SFltl left harbours Ijmuiden and Hoek van Holland with a total of 16 boats, to operate against convoys in the Scheldt estuary and in the Channel.
The 9. SFltl was detected by sloop "Guillemot" south of North Falls and reporteded by unencrypted Enemy Contact Report. Therefore, F.d.S. could warn the 8, SFltl which could thus avoid the sloop. When the flotilla run into the convoy "S 168" and "S 175" fired four torpedoes againsst a struggler of the convoy. The freighter „Halo“ (2.365 BRT) was sunk with a fan-shot. The trawler "Turquise " could rescue the entire crew. Half an hour before midnight the 8. SFltl was attacked by frigate "Stayner" with "MTB 495", "MTB 446", "MTB 496" and "MTB 497" angegriffen, whereby "S 168" (Oblt.z.S. Dau) got a 7,6 cm hit on the bridge, a 5,7 cm hit destroyed the port-torpedotube, aone man was killed, six men were wounded, among them the commanding officer.
The 8. SFltl (Kptlt Zymalkowski) advanced in direction North Forland and run shortly after midnight into the Sloop "Guillemot", a torpedo fired by "S 194" failed. "S 194" had to take a hit, one man was killed. But the flotilla could sail away from the slow Sloop and took again course on North Forland. About 03.00 lct. "S 701" detected targets with her FuMB (ESM) and the boats approached a convoy. Two fired torpedoes failed and the boats were taken under fire by Fort Tonge Sands and came into fights with the British Frigate "Seymour", the Sloop "Guillemot" and three MTB-groups consisting of three resp. two boats ("MTB 451", "MTB 452" und "MTB 450", "MTB 495" und "MTB 446" sowie "MTB 454" und "MTB 447"MTBs 451, 452 and 450, MTBs 495 and 446 as well as MTBs 454 and 447). In these actions collided "S 701" and "S 199". The bow of "S 199" (Oblt. z.S. Quistorp) was torn apart, the boat was so badly damaged, that could not be held afloat and therefore was scuttled. Due to a collision between the MTBs "MTB 495" was badly damaged.
The 8. SFltl came into fights with a British frigate, a British sloop and three MGB groups of three boats each without having sighted the convoy. In the course of this "S 701" and "S 199" collided. "S 199" (Oblt. z.S. Quistorp) was damaged so severely that she could not be held afloat and had to be scuttled. By a collision between the MTBs "MTB 495" was severely damaged.
In some sources - especially in Britsh - it is presumed that "S 199" was sunk by the AA-batteries of Fort Tongue Sand.
But according to a report of OLt.z.S. d.Res. Quistorp (†) on 25.08.2012 in a conversation with the WEB-Master the survivors were rescued after 6 1/2 hours in the life-rafts by minesweeper RCS "Neave" from the icecold waters of the Channel. One man was killed and three men were wounded by the propellers of "Neave". Oblt.z.S. Quistorp (†and 17 survivors were taken to Gillingham and became POWs. Oblt.z.S. Quistorp stated, that the seamanship and the friendliness of the Canadian "Neave"-crew was outstanding.

entering Ijmuiden "S 194" run aground but could free itself
again. "S 701" was taken under fire by own pickets, it had taken
so severe damages by the ramming that it did not become ready for action
again before the end of the war.
The other flotillas remained without successes. The 6. SFltl had to dismiss "S 704" shortly after lealving harbour becaus of engine trouble. The flotilla made way by going north of the battle scene, did not find the convoy and returned without result. On the march back "S 705" had a rudder failure and waterpenetration in compartment I. In the 4. SFltl "S 204" had enginetrouble and lost contact to the flotilla. By searching for the boat the flotilla lost so much time that it could no more get to the convoy. Therefore, the march back was started. The flotilla tried to operate against the convoy reported by the 8. SFltl. when the FuMB on teh boat of the guide failed and visibility went below 2000 m they marched back "S 175" was slightly damaged. On "S 219" an auxilliary engine failed, on "S 202" so strong vibrations occurred that the boat was damaged. Both boats had to be reported AKB.
In the night 23./24.01.1945 the 4., 6. awith eight boats left harbour for a torpedo-operation against the Thames-Scheldt-traffic. They had to return because of bad weather. The 5. SFltl with "S 98", "S 48", "S 85", "S 127", "S 92" und S 67" left harbour for a mining action east of Dungeon. Upon sighting by a contact-holder the boats were attacked by Wellington-bombers several times. Because of engine trouble on "S 92" and "S 67" the boats had to be dismissed and because "S 127" lost contact to the flotilla due to poor visibility only three boats laid mines on the route. The flotilla was after having laid the mines several times attacked by aircraft with bombs and aircraft weapon. The guide "S 98" got splinter damages on the bridge and at the ship's side.
During the night 24./25.01.1945 again mining operations were conducted against the convoy route off Orfordness. The 2. SFltl with "S221", "S 176", "S 209", "S 181" and "S 177" left harbour at 20.30. "S 176" had engine failure an was dismissed together with "S 209". The other boats laid their 12 UMB-mines as planned. The 4. SFltl also left harbour with "S 206", "S 175" and "S 703" in the evening. "S 204" could not take part because it has a damaged propeööer. The other three boats lais their mines as planned. The 6. SFltl with "S 211", "S 222", "S 704" and "S 223" laid 24 UMB. In a fight with a destroyer and MTBs several 20mm-hits were observed on the destroyer. All boats returned unharmed to their harbours.

the ice situation at Rotterdam had worsened, the harbour had a close ice
cover, on the Maas drifting ice was prevailing, the 4. SFltl with
boats "S 205" and "S 703", the 6. SFltl with "S 211",
"S 222", "S 223", and "S 704", and the 9. SFltl with "S 130" transferred to Ijmuiden on 26.01.1945.
On 29.01.1945 the 2. and the 5. SFltl left harbour with 11 boats to contaminate the convoy-route between Cromer and the Humber estuary. Short after leaving Den Helder the boats were attacked by Wellington-bombers without damages. While the 2. SFltl could lay the mines according to plan the bad weather caused a heard time to the boats, partly the n´mines jumped out of their rails, some even went over board. All boats came back with heavy damages caused by the sea and breakdown of the radiostations and had to be reported aKB.
In the night 05./06.02.1945 the 2. and the 5. SFltl left harbour for a mineoperation. Again the boats were attacked from the air immediately. Because of poor visibility the boats had to return. On their way back the boats were again attacked with bombs without taking damages.
On 08.02.1945 occurred another bombraid against the harbour of Ijmuiden with 15 Lancester-bombers. That resulted in the destruction of "S 193" having been locked in in the SBB since 15.12.1944.

On 12.02.1945 again a mining-operation was ordered, an action that was not carried out because of fog. The same happened on 15.02.1945.
the night 17./18.02.1945 another
minelaying-action was conducted in the Humber estuary by the 2. and the 5. SFltl
with 11 boats. Just after leaving harbour "S 209" had engine
breakdown and was sent back alone. In the poor visibility she did not find
the harbour entrance and had to roam around in the Texel area until the
next morning. The other boats laid their mines according to plan. On these
barriers sank the French destroyer escort "La Combatante" on
23.-032 and on 25.02. the trawler "Aquarius". The freighters „City of Lincoln“ (8039 BRT)
(3517 BRT) on 19. rsp. 28.02. got mine-hits without sinking.
In the night 20./21.02.1945 the 2. SFltl with "S 221", "S 176", "S 210"/"S 174", "S 181" and "S 209" performed a torpedo-operation againt a southbound convoy at Smith's Knoll. Boats "S 174" and "S 209" found themselves in the middle of the convoy. "S 174" fired two LUT, "S 209" two T-1 without hits. After reloading "S 209" fired two more torpedoes also without suiccess. When pulling back they heard five detonations. A freighter had burst in flames. "S 209" got several hits in a fight with escorts. A fire could be extinguished rapidly. One man was wounded. The first group of the 2. SFlktl and the 5. SFltl attacked a convoy south of Great Yarmouth and could report four rsp. seven hits. The British freighters „Goodwood“ (2.780 BRT) and „Blacktoft“ (1.109 BRT) sank, the ex-Danish freighter „Skjold“ (1.345 BRT) was fired to burn. Alle boats of the 2. SFltl had enginetroubles during this action because of salty diesel-fuel. The flotilla fell out for two days in order to remove and to clean the tanks.
In the hights 22./23.02. and 23./24.02.1945 the 4., 6., 8. and 9. SFltl laid mines on the Thames-Scheldt-route, on the way back three boats of the 8. and two boats of the 2. Sfltl downed a fighterbomber, "S 2092 another. On "S 2092 one man was wounded.
On the barriers laid on 21.02. the French motorfishingboat "Notre Dame de Grace" (26 BRT), on 26.02. the British steamer "Auretta" /4751 BRT) and the American freighter "Nashaba" (6054 BRT), on 27.02. the British freighter "Sampa" (7176 BRT) and on 01.03. The American Liberty-Ship "Robert L. Vann (7176 BRT) sank.
In the night 24./25.02.1945 another mining-operation was conducted by the 4., 8. and 9. SFltl in the area along the coast of Flandres. The 4. SFltl laid their mines west of Blankenberge and came into heavy fights with MGBs. On the way back "S 204" had water penetration and "S 703" rudder failure. warf ihre Minen westlich Blankenberge und geriet in heftige Gefechte mit MGBs. From the 8. SFltl "S 196" had rudder failure and was dismissed together with "S 209" as escort. The other three boats laid their mines northwest of Ostende. The 9. SFltl had several fights with destroyers and MGBs but laid their mines northwest of Zeebrügge. On the way back "S 167" (St.Ob.Strm. Seifert) had a rudder failure and rammed "S 705". "S 167" had to be given up dure to the severe damages suffered. The complete crew was taken over by the other boats. On "S 205" MechGefr. (T) Hans Brzemek was killed.
Since on 19.02.1945 for the first time Russian S-boats had attacked the traffic from and to Kurland, the MOK Nord ordered on 24.02.1945 the transfer of the 5. SFltl to the Baltic. The F.d.S. proposed to utilize the 1. SFltl in stead which was in the forming up phase, since all COs were experienced and familiar with the Russian way of conducting the war at sea, therefore, the 5. SFltl stayed in the west for the moment.
In the evening of the 28.02.1945 four boats of the 4. SFltl laid 24 mines in the same area. On their way back they came into a fight with frigate "Seymour" and destroyer escort "Cotswood". The boats tried to withdraw with 41 knots speed but "S 220" (Kptlt. Dross) got a hit in the starboard engineroom. A fire developped and finally the boat could only proceed with 10 knots and lost contact to the flotilla. Therefore, the CO decided to scuttle the boat. The compolete crew left the burnignboat after the secret documents had been destroyed. The boat was under fire by the escorts for a longer time. Just before midnight the boat sank after an explosion, probably of the torpodoes. The survivors were fished out of the water by the British. MaschMt. Josef Krzyzok, MatrObGefr. Gottfried Wahl und FkObGefr. Siegfried Bandemeer were not among the rescued.
Also the 6. SFltl had left harbour with five boats to lay mines butr only "s 212" could lay her mines. The 2. and the 5. SFltl with 11 boats were shadowed by enemy air recconnsaissance and near Norfolk detected the destroyer "Mackey" three S-boats at the buoy of Hearty Knoll and pushed them away. The frigate "Riou" and three MTBs detected four S-Boots and pushed them away. The 6. SFltl with only two boats could not penetrate the escorts and had to return without success.
In the night 09./10.03.1945 the 4. SFlt with "S 204", "S 205" und "S 219"; "202" and"S 703" had returned premature; conducted a mining operation off the SCheldt estuary. At the same timne the 9. SFltl with four boats laid mine on the Thames-Scheldt-route and had first to dogfight around with MGBs and than with destroyers.
In the nights following the boats tried to arrive at the convoy-route off the English eastcoast several times. The 4. SFltl had to break of its operation after a bomb-attack and developping fog. The 2. SFltl with six and the 5. SFltl with five boats went through the same. The 6. SFltl with four boats cancelled its minelaying operation because of poor visibility. The 9. SFltl was at sea for an operation with "Linsen" which were launched north of West Hinder.
Similar were all actions of the five flotillas in the hight to the 14.03.1945.
The 8. SFltl was not ready for action as result of an
attack with nine B17-bombers agaist Ijmuiden an the 14.03.1945 .
In the night to the 18.03.1945 the 4. and the 9. SFltl with together 10 boats had to break of a torpedo-operation in teh Thames estuary. The other three flotillas laid mines, the 5. SFltl with five boats 36 LMB off Cromer, Teh 2. SFltl with seven boats 36 LMB and ELM and teh 6. Sfltl with six boats 38 UMB and ELM on the Thames-Scheldt-route.
During the night 09./10.03.1945
the 4. SFlt with five boats, the 6. SFltl with four boats and the 9. SFltl
with four boats conducted a mine operation along the coast off the Schelde
estuary. It came into a fight with a MGB and four MTBs, which had lurked
for them without taking noteworthy damages.
During the night
11.03./12.03.1945 11 boats of the 2. and of the 5. SFltl had to break off
a torpedo operation off the British eastcoast because they did not find
targets. In the night 13./14.1945 six boats of the 2. SFltl, three boats
of the 4. SFltl, five boats of the 6. SFltl and three boats of the 9.
SFltl were to carry out a torpedo operation off Sheringham but they did
not find targets. On their way out and back in they had to take numerous
air-attacks. During the night17./18.03.1945 it went similarly for them.
The 2. SFltl could lay a
barrier with 30 mines off Smith's Knoll during the night 17./18.03.1945. A
torpedo operation of the 6. and 9. SFltl off Margate had to be broken off
due to fog.
The 6. SFltl laid 42 mines off the
English eastcoast with seven boats during the night 18./19.03.1945 and
attacked a convoy with torpedoes off Lowestoft.
Seven sunk ships and a torpedoed destroyer were reported. In reality only
the freighters "Rogate" (2.871 BRT) and
"Crichtoun" (1.097 BRT) were sunk.
In the night to the 19.03.1945 the 6. SFltl was at sea with "S 212", "S 213", "S 704" and "S 223"; "S 222" had returned because of a waterpenetration and "S 704" with engine breakdown, in order to lay mine northeast of Lowestoft. In the mining area it came to fight with a SGB and four MTBs, which had lurked for them. Afterwards the flotilla attacked convoy FS.1759 off Lowestoft with torpedoes. Seven sunk ships with 24.500 BRT and one torpedoed destroyer were reported. In reality only the freighters „Rogate“ (2.871 BRT) and „Crichtoun“ (1.097 BRT) sank.
In this night teh S-boats laid a total of 110 mines along the Englisch eastcoast, the 2., SFltl off the Humber estuary, the 5. Sfltl off Cromer, the 4. and the 9. SFltl off Orfordness.
On the mines laid in the night to the 18.03.sank on 19.03. the British freighters "Samelbu" (7253 BRT) and "Empire Blessing" (7062 BRT) aso well sa the Belgian trawler "Nelly" (75 BRT) and teh British landingship tanks "LST 80" (2750 ts). The American Liberty-Schip "Hadley F. Brown" was damaged by a mine on 20.03.1945.
During the night 21./22.03.1945
the 2. SFltl conducted a torpedo operation. On "S 210" the
compressor of the middle engine fell out. Since the flotilla consisted
only of three boats they turned around. On the march back the boats were
attacked by Beaufighters with rockets and machine guns. On the leading
boat "S 181" a fueltank, department VII and the armoured bridge
were hit, the boat burst to fire. The flotilla-commander (Kptlt.
Opdenhoff), the CO (Oblt.
z.S. Schlenk), and 12 men were killed in action. On "S
210" the air pipe for starting the engines was hit. Therefore,
"S 209" took over to rescue the crew of "S 181". The
burning "S 181" sank 34 nm northwest of Texel.
The 2. and the 5. SFltl were ordered to operate against a convoy but did
not find any targets.
The 2. and the 5. SFltl were ordered to operate against a convoy but did
not find any targets.
During the night 22./23.03.1945
the Thames-Scheldt-route again was subject to a minelaying operation of
the 4. and 6. SFltl. Already on their march to the mining area the boats were
involved in fights with MTBs. "S 205" got a hit in the bridge
superstructure. The FuMB was destroyed, ObStrm. Heinz Berg und FkGefr. Rudolf Bodenbergerwere killed in action, two men were wounded. On
"S 204" and on "S 704" two men were wounded on each
During the night 25./26.03.1945 the 4., 6., and 9. SFltl were underway again to contaminate the convoyroute with mines. Only the 9. SFltl could lay its mines. The two other flotillas were attacked and pushed away by the destroyers escort "Arendal" (Norwegian) and "Krakowiak" (Polish) and the British frigate "Riou". "S 205", "S 204", and "S 703" had to take hits, in the battle three man were killed on "S 205". On the mines of the 9. SFltl sank the American Liberty-Ship "Charles D. Melver" (/176 BRT) and der Greek freighter "Elefthenia" (7247 BRT) and on the 25.03. and the British motorlaunch "ML 466" (75 ts).
The 4. SFltl laid mines with four boats during the night 25./26.03.1945. In the course of that they were pushed away by MTBs and taken under fire by a destroyer escort. A torpedo fired at her went wrong.
On the mines laid on the Thames-Scheldt-route sank on 28.03. the Belgian trawler "St. Jan" (75 BRT) and the British Landing Craft "LCP 840" (11 ts). The Norwegian motor tankship "Belinda" (8325 BRT) was damaged.
Three more boats of the
Northsea flotillas were lost due to bomb hits on 30.03.1945 when 358 B-24
bombers of the USAF attacked Wilhelmshaven, "S 194" was laying
there for repairs after a mine hit in February off Ijmuiden, "S
186" and "S 224" were laying there for engine repairs.
Hatbour of Kriegsmarinewerft Wilhelmshaven early April 1945
Lack of fuel kept the boats in
their harbours during the first week in April. The transfer of the 5.
SFltl to the Baltic commenced on 02.04.1945.
Not earlier than in the night 06./07.04.1945 the 2. SFltl (Kptlt. Wendler) with "S 174", "S 176", "S 177", "S 209", "S 210" and "S 221" could leave harbour for a mining operation off the Humber estuary. After the flotilla-commander, KorvKapt. Opdenhoff, first bearer of the knight's cross with 142 sorties against the enemy was killed in action, Kptlt. Hugo Wendler became new flotilla-commander. As a commanding officer he was relieved by Oblt.z.S. Hans-Jürgen Stohwasser. Under fire of the British frigate "Cubitt" and the British destroyer escort "Haydon" the mines were laid.

Peter Port against Granville on 07.02.1945 and had entered St. Peter Port
again after the action had been abandoned. With only one operational
engine the boat could not participate in the operation next day and
transferred to St. Lorient. On board were six army officers among them
three bataillon commanders. The CO, Lt.z.S. Nikelowski, had a deadly
traffic accident in April. The boat stayed at St. Lorient and
was sold by the French navy on 27.06.1951 for breaking up.

It is of interest that the radiotelegrams encrypted with the supposedly safe "Enigma" were not only intercepted but also decoded by the British reconnaissance within a short time, so that the enemy was well informed about the movements of the S-Boats. The following radiotelegrams are serving as excamples:
The above Enigma-radiotelegrams are from the Archives of Flemming Hansen.
The mentioned new-constructions presumably were boats of the loot "S 307" through "S 321", which were never commissioned. Thereof "S 316" was lost by scuttling in the Weser estuary. The whereabouts of the other boats are not clarified. Probably they went to Henry Rasmussen Yacht & Baadeværft at Gl. Hestehauge close to Svendborg/Denmark for final fitting-out. It is assumed that eight of them were scuttled on 6th May 1945 in the Lunkebight/Denmark.
