1 Oct 1939 The 2,239-ton Belgian merchant steamer Suzon was sailing to Cardiff, Wales, United Kingdom loaded with 2,400 tons of pit props for the Welsh mines. The ship had been built in Sunderland, England, United Kingdom by S. P. Austin & Sons, and was owned by a London shipping Company and then named Portwood. In 1930 she was sold to the Belgians and renamed. At 1845 hours German submarine U-35 (Kapitänleutnant Werner Lott) attempted to stop the neutral and unarmed steamer with light signals about 42 miles 330 degrees from the French island of Ushant but the Belgians put on steam and tried to escape. Warning shots were fired which actually hit the ship forcing the Belgian Captain, R. Lejeune, to stop and abandon the ship, knowing that the cargo would be classed as contraband. After the crew were clear the submarine fired a torpedo that struck on the port side of the Suzon abreast the funnel which broke the vessel's back, the two halves sinking almost immediately. The Belgian crew were picked up by HMS Acheron (H 45) commanded by Lieutenant Commander R. F. W. Northcott RN which was escorting the nearby convoy MB-10.

The Netherlands made an official protest to Germany regarding this violation in international shipping law.

21 Oct 1939 British light cruiser HMS Orion and Canadian destroyer HMCS Saguenay located German tanker Emmy Friedrich in the Yucatán Channel, and began to move to intercept.

23 Oct 1939 On being told by Admiral Erich Raeder that he lacked adequate support from both the civil administration and the other two military branches, Adolf Hitler sent a memorandum to the Air Force and Army Commanders-in-Chiefs as well as to the Ministers concerned. The memo made it clear that "All measures for attacking the merchant shipping and economic resources of Great Britain were to be directed through the O.K.W. (Oberkommando der Wehrmacht)." This gave Raeder the chance to press for a relaxation of the restrictions on sinking neutral vessels trading with England. Hitler however remained adamant that any incidents should be forbidden until he was ready to strike on land. He told the admiral that he was worried about the name of the heavy cruiser Deutschland. As soon as she arrived back her name was to be changed to Lützow. "Should she be sunk with her present name it would have serious repercussions back home." Hitler then ordered a meeting of Naval Staff in Berlin, Germany on 1 Nov 1939.

24 Oct 1939 British light cruiser HMS Orion and Canadian destroyer HMCS Saguenay intercepted German tanker Emmy Friedrich in the Yucatán Channel; Emmy Friedrich's crew scuttled the ship to avoid capture.

24 Oct 1939 German submarine U-37 sank British steamships Menin Ridge by torpedoes and Ledbury by gunfire off Gibraltar.

Rollmann had fired two torpedoes and claimed to hit the Malabar and an escorting destroyer, however only Malabar was hit. Malabar was the ship of the convoy commodore, five crew were killed in the explosion, the remaining 66 crew and the master, Henry Herbert, the commodore Rear Admiral G. W. Taylor and his two staff members all got away in lifeboats and were clear when the vessel sunk 180 miles south of Land’s End, Cornwall, England. They were all picked up by the G- and H-class destroyer HMS Grafton (H 89) and taken to Plymouth on the south coast.

30 Oct 1939 The 4,666-ton steam merchant Cairnmona was making her way to Newcastle, England, United Kingdom with a cargo of copper and grain and 3 miles off Rattray Head, Aberdeenshire, northeast Scotland, United Kingdom when she was torpedoed by German submarine U-13 (Kapitänleutnant Karl Daublebsky von Eichhain) at 2250 hours. The Cairnmona had been dispersed from convoy HX-5 and would be the only ship sunk from it. Three crew were killed in the explosion, the master, Fred Wilkinson Fairley and 41 crew members took to lifeboats and were later picked up by the British drifter HMS River Lossie.

30 Oct 1939 British anti-submarine Trawler HMS Northern Rover out from Grimbsy, north-east Lincolnshire, England, United Kingdom, was sunk with a torpedo fired from German submarine U-59 (Oberleutnant zur See Harald Jürst) at 2335 hours. The trawler had been requisitioned by the Admiralty to be used against German submarines, as an armed boarding vessel and to be used as contraband hunters. U-59 attacked as the Northern Rover was patrolling the Kirkwall area, 100 miles west of Sumburgh Head in the Shetland Islands. The Commander, Lieutenant H. M. Macpherson RN and the 25-man crew were lost.

31 Oct 1939 At 0525 hours the 5,874-ton French merchant steamer Baoulé was heading to Bordeaux, France with a cargo of palm kernels, rubber, cocoa, and coffee in convoy K-20. The ships had just passed 45 miles west-northwest of A Coru?a, northwest Spain when Baoulé was torpedoed by German submarine U-25 commanded by Kapitänleutnant Viktor Schütze. Two torpedoes hit the ship which sank quickly, 13 crewmembers lost their lives.

1 Nov 1939 In a meeting with General Wilhelm Keitel and Lieutenant Commander Karl-Jesko von Puttkamer, Adolf Hitler's liaison officer with the Naval War Staff in Berlin, Hitler repeatedly told the officers that the name of the cruiser Deutschland should be changed and the ship was to avoid any action the same orders were to be issued to the Scharnhorst and the Gneisenau. Hitler was worried that any action would bring out the British Grand Fleet before air protection was organised. The Graf Spee, on station in the South Atlantic was to be ordered to be ready to sail to the Indian Ocean. Any operations of battleships must be held until Italy entered the war and the British Forces consequently held down. Submarine warfare was to be intensified. Passenger ships could be attacked and neutral ships would be attacked once a state of siege be declared against Britain. Hitler would not give priority to the production of submarines however, as Army equipment and ammunition supplies were of prime importance. Erich Raeder sent a copy to Admiral Karl Dönitz, Commander of the Submarine Arm with a note saying that in order to carry out a large scale submarine war then continuous pressure would be necessary.

11 Nov 1939 Built by Newport Ship Building in the United States, the 4,576-ton Greek owned Elenor R. struck a mine off the Shambles, Portland on the British south coast.

8 Dec 1939 German submarine U-48 sank the ship Brandon of Allied convoy OB-48 in the Celtic Sea at 1155 hours. Master Richard Black Chisholm and other survivors were picked up by the Belgian trawlers Marie Jose Rosette and Tritten and landed at Milford Haven, Wales, United Kingdom. U-48 misidentified her victim as the Navasota, but this ship had been sunk by submarine U-47 three days earlier.

12 Dec 1939 Off the British coast, at 0815 hours, the 496-ton ship Marwick Head taking coal to London from Boness, near Grangemouth, Scotland, struck a mine laid by U-59 and sank 0.5 miles South of the North Caister Buoy, off Great Yarmouth, Norfolk, England. Five crew members were lost, the captain and four other crew were rescued and taken to Great Yarmouth.

12 Dec 1939 The 8,485-ton British registered motor tanker British Liberty was on route from Haifa, Palestine for Dunkerque, France with a cargo of crude oil.

14 Dec 1939 HMS Ursula sank German escort ship F9 with a torpedo in the North Sea.

9 Jan 1940 The British submarine HMS Starfish (N19) attacked a German minesweeper off the German North Sea coast in the Heligoland Bight. However this attack failed because, due to drill error, the torpedoes remained stuck in the tubes. She returned for second attack but the hydroplanes jammed and the commanding officer Lieutenant Thomas Turner decided to remain under water at the depth of about 27 metres for the remainder of day to carry out repairs. The German minesweeper M-7 located her and dropped 2 depth charges which did no damage. At 1050 hours one of the electricians asked for permission to restart one of the Sperry motors to prevent the gyro from wandering, and the request was granted. No sooner the motor started, 4 depth charges rained on top of the boat, fairly close aboard, causing widespread damage. At 1440 hours another depth charge attack was carried out, 20 of these falling fairly close to the hull, shearing rivets and starting plates which began leaking. By 1800 hrs the situation inside was serious, the engine room crankcases and starboard main motor bearings were flooded, the torpedo trenches and bilges were full, water was pouring through the starboard engine clutch and lapping the starboard main motor casing. HMS Starfish laid on the bottom until Lieutenant Turner, having formed the opinion the enemy was not likely to leave the vicinity in the near future, gave the order to surface at 1820 hours. In order to accomplish this, the submarine was forced to drop the ballast keel, barely making it due to loss of high pressure air and water in the hull, coming up at a 45-degree angle. She sank very shortly after with no loss among the crew, which was picked up by the waiting ships and taken as prisoners of war.

9 Jan 1940 Carrying a cargo of coal from West Hartlepool on the eastern coast of England, United Kingdom to Drammen, Buskerud in Norway, the Norwegian 1,334-ton steam merchant Manx was torpedoed at 0221 hours as she cleared Kinnaird Head in north Scotland by U-19 (Joachim Schepke). Eight of the crew managed to get to an upturned lifeboat but four died of exposure in the cold water. Four men endured eight hours on the boat until rescued by the Norwegian freighter Leka, the other 2 who had got on a raft were seen by Isis, another Norwegian ship. Originally it was thought that the Manx had hit a mine however, records show that U-19 had indeed claimed a merchant ship on this date, Schepke made no mention of the ship being Norwegian therefore neutral.

11 Jan 1940 The Fredville, a 1,150-ton Norwegian steam merchant, was attacked and sunk approximately 100 miles east of the Orkney Isles at 1632 hours. There had been two explosions in the hold, the first seemed to cause little damage but 10 minutes later a much larger explosion broke the ship in two. The ship in ballast was on her way to Methil, Scotland, United Kingdom. 5 of the crew found time to get into a lifeboat and made repeated attempts to find any more survivors from the after part of the ship that remained afloat but none were found. The 5 men were picked up by a Swedish ship and taken to Kopervik, Karmøy Island, Norway. It was probable that the ship was sunk by German submarine U-23 (Otto Kretschmer), though at the enquiry held later the crew said that they thought there could have been bombs put into the coal bunkers by the Wollweber Group who were a group of Communist saboteurs who were responsible for the loss of several Scandinavian ships; they also stated that the ship was marked with the Norwegian flag and had navigation lights on.

17 Jan 1940 The Norwegian 1,140-ton steam merchant Enid carrying wood pulp to Dublin, Ireland was one of two ships sunk 7 miles north of Muckle Flugga, Shetland Islands, Scotland, United Kingdom. The other vessel was the 4,751-ton British freighter Polzella. The Enid went to the assistance of the British ship which sank quickly after the torpedo fired by U-25 (Viktor Schütze) struck (all crew members aboard Polzella would be lost), but the submarine surfaced and fired a shot across the bow to stop her. Enid turned away, fired three shots from her deck gun, and then was abandoned by her crew, who took to two lifeboats. The Germans then fired 21 rounds from the deck gun and hit Enid seven times, setting her on fire. At 1410 hours, a coup de grâce was fired that broke the ship in two. The forepart sank immediately while the burning stern remained afloat and was later scuttled by the destroyer HMS Firedrake (H 79), which had been sent to the area to hunt for the submarine together with HMS Fortune (H 70) and several anti-submarine trawlers. Eight survivors in one lifeboat made landfall after 3 hours at Burra Firth on Unst, one of the northern Shetland Islands. The master and 7 crew members were picked up by the Danish motor merchant Kina.

22 Jan 1940 The unescorted Norwegian 2,589-ton merchant steamer Songa was stopped by German submarine U-25 in calm seas 200 miles west of the Scilly Islands. Viktor Schütze ordered the Songa's crew to abandon the ship after he declared her cargo of copper, tin and foodstuffs to be contraband. A single torpedo then sent the vessel to the bottom; the submarine's crew supplied the Norwegians with rum and gave them a course to steer the two lifeboats towards the shipping lanes.

2 Feb 1940 British minesweepers Sphinx (J69; Commander John Robert Newton Taylor), Speedwell, and Skipjack were sweeping an area about 15 nautical miles north of Kinnaird's Head near Fraserburgh north-east Scotland, United Kingdom when attacked by German aircraft. A bomb pierced the fo'c'sle deck of 889-ton HMS Sphinx (John Robert Newton Taylor, RN) and exploding destroying the fore part of the ship. The commanding officer and forty of the men were killed in the explosion; survivors were taken to HMS Speedwell. Sphinx remained afloat and was taken in tow by minesweeper HMS Halcyon (J42) but steadily flooded.

3 Feb 1940 The Norwegian steam ship Tempo was on a voyage from Methil, Scotland, United Kingdom to Hull, England, United Kingdom with a cargo of paper. Being a neutral the ship was marked as such. She was attacked by three German aircraft as the ship passed close to the Longstone Lighthouse, seven miles off the coast. The first attack was with machine guns after which the aircraft attacked with bombs, one of which hit the stern of the Tempo. The captain immediately ordered the ship to be abandoned as the Tempo was sinking rapidly. A third pass over the ship was made in which four bombs were dropped near missing the freighter, the survivors reported that the aircraft then fired at the lifeboats only missing them by a metre. The bombers continued to circle the area for twenty minutes as the lifeboats headed for the shore however the boat under command of the first mate capsized in the heavy surf and five of the men were drowned, the sole survivor luckily being washed onto the beach. The other boat under command of the captain were picked up by a rescue vessel. An inquiry was held in Oslo, Norway where the attack was noted and the German authorities notified of the event.

9 Feb 1940 After sundown, during this dark night with minimal moon light, six German merchant ships sailed out of Vigo, Galicia, Spain, intending on breaking the Allied blockade. The ships were Arucas, Morea, Orizaba, Rostock, Wahehe, and Wangoni.

9 Feb 1940 British trawler HMS Fort Royal commanded by Lieutenant Commander Edgar King and trawler HMS Robert Bowen commanded by Skipper Lieutenant John Clark, RNR were sunk by German aircraft off Aberdeen, Scotland, United Kingdom. Clark was killed.

10 Feb 1940 The 1,259-ton Norwegian merchant steamer Silja had been requisitioned by the Norwegian authorities in the autumn of 1939 and had left from Trapani in Sicily, Italy on 26 Jan 1940 with a cargo of salt for Bergen, Norway via Gibraltar where she departed on 5 Feb 1940. At 2059 hours, German submarine U-37 (Korvettenkapitän Werner Hartmann) reported firing a single torpedo at an unescorted steamer about 75 miles west of Cape Clear, Ireland. The vessel broke in two after being hit aft. The stern part sank immediately, and the fore part followed a few minutes later. There were no survivors of the 15-man crew.

10 Feb 1940 In response to the six German merchant ships that had sailed out of Vigo, Spain in the previous night, search forces under Commander-in-Chief Western Approaches, Admiral Dunbar Nasmith, were formed. This group consisted of ships of the Home Fleet (battlecruiser Renown, aircraft carrier Ark Royal, cruiser Galatea and destroyers), of the Western Command, the Northern Patrol and of the French Admiral-West.

11 Feb 1940 At 2230 hours the 8,022-ton tanker Imperial Transport was struck on her port side at the empty #6 tank by a torpedo from U-53 (Korvettenkapitän Harald Grosse). The ship started to break in two 200 miles northwest of the Butt of Lewis. Members of the crew got into two lifeboats but lost two men in the dark night. Later the ship was reboarded after it appeared that the stern section was not going to sink. They were unable to radio for help but managed to sail the stern 130 miles at 4 knots before meeting 4 British destroyers. Attempts were made to tow the half over the next two days with tugs but the weather got worse and the crew had to be taken off again. The section was beached on the Isle of Bute in Kilchatten Bay. The stern section of Imperial Transport was later salvaged and docked in Elderslie Dockyard, Glasgow, Scotland, United Kingdom. The battered bulkhead and all distorted material cut away and fitted with a new fore part that was built to the original plans by William Hamilton & Co Ltd, and was launched bow first with deckhouse, mast, derricks and auxiliary equipment complete. The ship returned to service in June 1941.

11 Feb 1940 The 1,854-ton neutral Swedish merchant steamer Orania was carrying maize and bran from Brazil to Malmö, Sweden when she was struck by a single torpedo from German submarine U-50 (Kapitänleutnant Max-Hermann Bauer) in the Norwegian Sea at 2354 hours. The ship sank within three minutes of the explosion 65 miles north-northeast of the Flugga Lightship, Shetland Islands. U-50 had spotted the ship and although she was lit up, Bauer reported that he could not confirm that the ship was Swedish. All the crew got away in two lifeboats but one with 14 men was never seen again. The others were picked up by the destroyer HMS Faulknor, transferred to HMS Foxhound, another destroyer that took them to Lerwick, Shetland.

11 Feb 1940 French sloop Elan captured 2,542-ton German merchant ship Rostock in the Atlantic Ocean. Rostock had sailed out of Vigo, Spain on 9 Feb in an attempt to break the Allied blockade.

15 Feb 1940 The 398-ton trawler Peridot, requisitioned by the Admiralty in Aug 1939 and fitted out as an armed Anti-submarine vessel, struck a mine laid by a German submarine in the English Channel.

16 Feb 1940 At the start of the day, 20 miles north of Kinnaird Head, Fraserburgh, Scotland, United Kingdom, German submarine U-14 (Oberleutnant zur See Herbert Wohlfarth) sank Danish ships Rhone (killing 9) and Sleipner (killing 13) shortly after midnight; 41 survivors were later picked up by Swedish trawler Standard and HMS Kipling. Toward the end of the day, at 2125 hours, 10 miles north of Kinnaird Head, U-14 struck again, sinking the 1,526-ton neutral Swedish coal ship Osmed, which sank by the bow 2 minutes after the torpedo struck, 10 of the crew were lost, the remaining 7 were picked up by the British trawler Loch Hope and taken to Scrabster, a small harbour in Thurso Bay Caithness, Scotland. 10 minutes later, at 2135 hours, U-14 sank the 1,646-ton neutral Swedish coal ship Liana carrying coal from Blyth to Halmstad, Sweden. She went down within a minute, 10 crew members managed to get off the vessel and these too were picked up by the trawler. Eight of these later boarded the Santos to return to Sweden but the ship was sunk on the 24 Feb 1940 and 6 of them were drowned.

17 Feb 1940 At 0200 hours, the 1,819-ton Norwegian freighter Kvernaas sailing unescorted was hit by a single torpedo from German submarine U-10 (Oberleutnant zur See Joachim Preuss) and sank after just 5 minutes 4 miles north-west of Schouwen Bank, Netherlands. The crew got off in 2 lifeboats and were picked up by a Dutch steamer Oranjepolder on her way to London, ENgland, United Kingdom, but turned back and took the survivors to the pilot station at Hoek van Holland the following day. Various sources say that the Kvernaas struck a mine.

18 Feb 1940 British Royal Navy D-class destroyer HMS Daring (H16; Commander Sydney Alan Cooper), whilst escorting Allied convoy HN-12 from Norway, was attacked by German submarine U-23 (Kapitänleutnant Otto Kretschmer) at 0354 hours. Two torpedoes struck the 1,375-ton ship and she sank immediately about 40 miles east of the Pentland Firth, Orkney Islands, Scotland, United Kingdom. 147 officers and men were lost. 1 officer and 3 ratings were picked up from a float by HMS Ingleield (D02) and taken to Scapa Flow, Scotland and another rating was found amidst the debris and rescued by the submarine HMS Thistle (N24) assisted by HMS Ilex (D61) and taken to Rosyth, Scotland.

There were four crewmen aboard each ship, and even though some survived the sinking initially, commanding officer Oberleutnant zur See Hans Bartels of M1 did not pick up any survivors, thus all of them would eventually be lost. Bartel suspected that the trawlers were reporting German movements to the British while flying the flag of a neutral nation.

26 Feb 1940 The 4,354-ton German merchant ship Orizaba, having successfully breaking the British-French blockade outside of Vigo, Spain, ran aground off Troms in northern Norway.

The crew abandoned ship in two lifeboats and after questioning the Germans gave them a course to steer to the nearest land. At 0810 hours the submarine shelled and set the Lagaholm alight after which she sank. The survivors were picked up by a Norwegian merchant ship Belpamela and taken to Kirkwall and North Ronaldsay.

3 Mar 1940 British cruiser HMS York stopped the 3,359-ton German steamer Arucas 50 miles south of Iceland. Arucas' crew of 42 Arucas scuttled the ship. 3 died in the process. 39 men were picked up by HMS York. Arucas had sailed out of Vigo, Spain on 9 Feb in an attempt to break the Allied blockade.

At 0412 hours, the Tilia Gorthon was hit in the engine room by another G7e torpedo after the crew had abandoned ship in two lifeboats and sank. The survivors were picked up by the British sloop HMS Leith (U 36). The Tilia Gorthon had previously been on voyage from Bahia, Brazil to Gothenburg, Sweden but was stopped by a British warship and sent to Liverpool, England, United Kingdom and then to Nantes, France, however, near the Loire a new order sent her to Quiberon Bay, France and finally ordered the ship back to Liverpool.

The attacker must have been German submarine U-122 (Korvettenkapitän Hans-Günther Looff), which was lost shortly afterwards but reported sinking a large freighter in a radio message at 0030 hours on 21 Jun 1940. The Empire Conveyor did not sink immediately, but because the aerials had been damaged the radio operator was unable to call for help. Luckily a flying boat on patrol in the area arrived, dropped bombs to keep the submarine submerged and alerted the British Admiralty. The tug HMS Amsterdam was sent out, escorted by the rescue tug HMS Atherstone (L 05) and the destroyer HMS Campbell (D 60), but at 1600 hours she suddenly sank before the ships arrived. The crew had abandoned ship in three lifeboats and several rafts, but one boat swamped during launch.

The explosion blew open the hatches of No. 1 hold, put the Asdic and steering gear out of order and mortally injured two crewmen. The panic party abandoned the now slowly circling ship in two lifeboats but the submarine did not surface but fired a coup de grâce after about an hour that hit on port side amidships, causing her to slowly settle by the bow until sinking with a list to port at 1230 hours. 54 became missing and would be never found; 40 would be rescued.

21 Jun 1940 The 7,638-ton French tanker Brumarire was sunk by German aircraft in the Atlantic Ocean. The crew of 37 was saved by the British destroyer HMS Griffin (H 31) and landed in England, United Kingdom.
