S-Boat-Wrecks in the Western Baltic

Besides of the four wrecks in Lunke Bight in the east of the little island Tåsinge near Svenborg/Denmark, divers have found in 2010, we today know of wreckpositions of three Kriegsmarine S-boats. Thereof the wreck of "S 103" is clearly identified. The positions "W 1" and "W 2" are S-boat-wrecks found by divers, which have until now not been identified positively. Positions "R 1" and "R 2" are engagementpositions included in the fighting-reports of RAF Squadron 193 in which S-boats or assumed S-boats have been attacked. Position "O 1" is a postition af a S-boat-wreck obtained by electronic location.


Wreck in Position 54o 16'N 010o 07'E - "S 103"

The wreck is from boat "S 103" (Oblt.z.S. Hans-Wulf Heckel) sunk by Typhoon IB-fighterbombers about 2 miles southeast of Mommark/Als on 03.05.1945. The wreck lies on 35 m waterdepth in vicinity of a seacable and has not been destructed as planned by the Danich Navy although torpedoes as well as artillery-ammunition have been found on board. 

The boat was en route from Svendborg/Denmark to Flensburg in order to find out if the British had arived there already. On board was a totally inunpractised crew an to guest when the boat around 16.00 was attacked by Typhoon IB-fighterbombers with rocket-bombs and aircraft armaments off Mommark as a surprise. The boat had to take two direct hits and sank. Commanding Officer and 11 men of the complement partly wounded were picked up ba a Danish fisherman and taken to Mommark.


Wreck in Position 54°39,7′ N 11°11,8′ E- Unknown S-Boat Type "S 100" - W 1

The naval vessel that according to the report of the police-station Nakskov was scuttled on 06.05.2016 after a bombing northwest of the harbour Rødbyhavn on the southern tip of the island Lolland was clearly identified by diving aktivities as a S-boat belonging to type "S 100". The available underwaterphotographs are verifying this identification. The positions reported by the divers and obtained. Actually the postion stated by the divers and the postion obtained by electronic means differ but ist must be assumed that it is one and the same wreck.

The boat was scuttled after a bombhit by its crew on 06.05.1945 northwest of R€dbyhavn. Commanding officer and 19 of 23 men of the complement went ashore near Kramnitze with help of the remaining liferafts on board and reported themselves at  the police-station.

At this point in time "S 226" (Lt.z.S. d.Res. von Glasenapp) was already scuttled north of Heiligenhafen. The other two boats lost in the Western Baltic during the last days of war, "S 191" and "S 301" were logged as missing since 05.05.1945 according to the KTB of the Seekriegsleitung. Both boats had been so badly damaged by a ramming in th eastern entry of Femern Sound that they had beene scuttled by their crews. 

Since no KTBs are available for the boats of the 2. S-Schoolflotilla no losses of boats of type "S 100" in the last days of war. 

Therefore, the wreck off Rødbyhavn must be accounted for tobe from an unknown boat of Type "S 100". 

The assumptions of Herr Reinhard Öser and ofm Bubblewatcher Tauchservice, that it can be the wreck of "S 226"are contradicted by the report of tzh Commanding Officer available to us.


Wreck in Position 54° 40' N   010° 42' E - "S 170" - W 2

 The wreck two miles southwest of Keldsnor lighthouse in the south of the island Langeland is from a S-boat of class "S 100" according to the available unterwaterphotographs.

In our opinion the wreck is of "S 170". The boat was on route from Travemünde to Flensburg together with " S 226" (Lt.z.S. d.Res. von Glasenapp) and two minesweepers on 03.05.1945.According to the report of the former Commanding Officer of "S 226", which is available to us, the force was engaged by 12 Typhoon IB-fighterbombers west of Femern Belt.  During a further attack 20 minutes later north of Putlos "S 226" waas camouflaged and did not perform any defensive action while "S 170" fired from all barrels and tried to escape at high speed. During this attack one of the minesweepers was badly damaged. When "S 226" proposed to commonly sail to assist the mainesweeper the crew of "S 170" mutinied. "S 226" rescued the survivors of the minesweeper and shortly thereafter scuttled off Heiligenhafen. the further whereabouts of "S' 170" are not stated in the report. 

The last known position of "S 170" north of Putlos and the fact, that was counted as missing, lead to assume, that the sinking off Keldsnor without any reporting of the loss or of survivors was due to a possible minehit.

The possibility stated by Herr Reinhard Öser and by Bubblewatcher Tauchservice that it could be the wreck of "S 22" is considered as untenable by the notification of the last radio operator of "S 22", Herr Raimund Schulz, communicated to the Web-Master on 17.01.2016 that "S 22" sank in the harbour of Wilhelmshaven in early April 1945.


Scuttling-Position 54°23′ N 11°05′ E - "S 191" and "S 301"

The position stated by Hümmelchen for the scuttling of boats "S 191" and "S 301" in the easterly entrance of Femernsound on relatively shallow water leads to assume that the wrecks were removed by explosive means or by recovery in the years after the war because they were hampering shipping and fishery in that position.


Scuttling-Position ca. 54°25′ N 10°59′ E - "S 226"

The scuttling-position of "S 226" stated in the report of the Commanding Officer north of Heiligenhafen also on relatively shallow water leads to think, that the wreck was removed by explosive means or by recovery for the same reasons.
