German submarine U-37 was a Type IXA[3] U-boat of the German Navy (Kriegsmarine) during World War II.[1] The submarine was laid down on 15 March 1937 at the DeSchiMAG AG Weser yard in Bremen, launched on 14 May 1938, and commissioned on 4 August 1938 under the command of Kapitänleutnant Heinrich Schuch as part of the 6th U-boat Flotilla.[1]

Between August 1939 and March 1941, U-37 conducted eleven combat patrols, sinking 53 merchant ships, for a total of 200,063 gross register tons (GRT); and two warships, the British Hastings-class sloop HMS Penzance, and the French submarine Sfax (Q182).[1] U-37 was then withdrawn from front-line service and assigned to training units until the end of the war. On 8 May 1945 the U-boat was scuttled in Sonderburg Bay, off Flensburg.[1] U-37 was the sixth most successful U-boat in World War II.[4]

♪ [fanfare] ♪ This picture was photographed in combat zones By cameramen of the Mediterranean Allied Air Forces. And by pilots of the 12th Air Force. Who, during missions against the enemy, operated automatic cameras in their planes. Behind the pilot, shooting forward and back. Under the wing. In the wing, timed with the guns. In the wheel well. In the instrument panel, photographing the pilot himself. The commanding general of the United States Army Air Force, General Carl Spaatz, Has asked me to tell you something about this picture. I don't think I could any better than just to read from his telegram to me. Thunderbolt was made in 1944 - ancient history - As made about one fighter bomber group in the Italian campaign. It happens to be an American group, But the same story could well be told of the Royal Air Force groups Which participated so gallantly in the same air offensive. Matter of fact, the story belongs to all men who fought for freedom, And did it a long way from home. Signed, Spaatz. Thank you. [somber music] To the Italian man in the street, or what's left of the street, This is the fulfillment of a promise - The promise of the Fascists to build a 20th century Roman Empire, conceived in tyranny, And dedicated to the proposition that some men were meant to be slaves of other men. Special victims were the children. They saw things not meant for children's eyes. From the air, Italy is more remote. The airman never sees the face of the people, only the face of the country. From the air, you look down at the mountains. Look down, and wonder how our men on the ground ever got through. Mountains and rivers. The Volturno - lot of American blood in that one. Natural barriers - made other campaigns tough too. Exhausted Hannibal's elephants, Caesar's legions. For the airman, the ground war is remote. The only war you really understand is the air war. You can see a pattern to it. Lots of the country, never been touched. Little towns that walk the ridges like tightrope artists, to keep from falling off. This one didn't matter. When something did matter, that was another story. [fanfare] This is how we changed the face of Italy from the air. They boasted Italian trains ran on time - not these. This is what we did to the face of Italy. There's a story behind why we did it, and how we did it. The story starts on an island 60 miles off Italy's coast. The island of Corsica. Corsica. Rugged, primitive, mountainous, malarial. Here, they still remember a local boy who put Corsica on the map 150 years ago. This island part of France was liberated by the French in September '43. But you can still find a few Germans, Left by the way side where they fell, in the shadow of our air drones. Alto Air Base, Sunday morning. Here, Sunday is like Monday, And Monday is like every other day in the week. A working day. The engines wake you at dawn. In your sack, you can hear the crew chiefs pre-flighting their planes. Getting them ready for the day's missions. This is how you live when you're an airplane driver. Fighting an air war, 20 minutes from the Germans in Italy. You're used to it. You've been washing out of your helmet since July of '42. From the Holy Land to Africa, Across the desert, Egypt in El Alamein, To Libya and Tunisia. 1,300 miles. You moved when the infantry moved. Sicily, and Italy, 58 moves in two years. Now, Corsica. This is the best year you ever had! Call it, "The Country Club." [cheery music] When you talk about air power, this is what you mean - You mean "Spanky" Manda. Major Francis S. Manda of Mentmore, New Mexico. Sqaudron Operations Officer. Not a desk job. Got over 170 missions, working for 200. He's 22. You mean Captain Howard Hickok of Ames, Iowa. He's a flight leader. Just had 30 days in the states. Time to get married, then come back. He's 23. Or, in his Italian general's trailer, Gil Wymond, Louisville, Kentucky. Hardly looks old enough to vote, but he's boss of a squadron. He signs his letters "Gilbert O. Wymond, Lt. Col., Air Corps, Commanding. 'The Old Man'." He's 24. [solemn music] Sunday morning, for the 57th Fighter Group, Pre-squadrons a thousand men, another day begins at Alto Air Base. You could close your eyes and see it this way, spread out like a diagram. Been home sweet home for some time. Good steel-mat runway, 150 by 6,000 feet. Tower call sign is "Breakneck." Lots of jokes about that. We share the field with a French fighter group. Don't speak the same language, but we fly the same airplanes against the same enemy. Each lost a man yesterday. We get along. Group Commander Lt. Col. Archie J. Knight, West Point, 1940. He's 27. First mission today is a 65 squadron show. Briefing, right after breakfast. Informal, short, to the point. Park yourself on a bomb crate, and get your escape kit. Enemy money, instructions to get you back through the lines, just in case. The S2 tells you about your target. He doesn't have to draw it for you, you do this every day. Sometimes, two or three times a day. Gil Wymond will lead the show, so he lays out the job. That's a nurse's hat, his girl's. Wears it for luck. Need all you can get. The brass upstairs plans the war. They want something done, you pick up the phone. You do it. Don't always know why they send you out on a mission, don't always care. But, you know there's a reason. A good one. Today, the missions are going out because in Italy Our armies have been stopped cold at the Gustav Line. Of course, the narrowest and most mountainous part of the peninsula. U.S. 5th Army, British 8th Army, stopped for five months. At Anzio, 100,000 men sweating it out. We couldn't move. Stalemate. March 13th, we bombed Cassino, our immediate objective. Good job of bombing, didn't work. Our infantry didn't advance. It was the wrong use of air power. Wrong because we were not taking advantage of the airplane's greatest asset - Its ability to get behind the enemy. That's what the air planners wanted to do - get behind him. Lt. Gen. Ira C. Eaker, commanding all the air in the Mediterranean. British, French, and American. Maj. Gen. John K. Cannon, "Uncle Joe", commanding the 12th Air Force. And Brig. Gen. Gordon P. Saville, 12th Tactical Air Command. The brass upstairs who run the air war. They said, "Let's not hit him here," "Let's hit him here." "Let's isolate the battlefield." "Let's weaken the entire German front." By depriving it of supplies: Fuel, food, ammunition, reinforcements. They called the plan Operation Strangle. This is what we want to do with airplanes - How? Lot of railroads in Italy. This is the enemy. Keep the trains from getting through. Lot of rivers in Italy, and over 700 major bridges. We figured if a train came to one, and it wasn't there, Be kind of tough to get across. Medium bombers got many of the important ones. But bridges are long, narrow targets. Difficult to hit and destroy. Took a lot of trips, bombs, planes, men. We started to use a special weapon - A fighter bomber, the P-47 Thunderbolt. One engine. One man. One bomb on each wing. Extra fuel tanks for range. 65's crew chiefs taxi from the dispersal points. To the end of the runway. Line up the squadron. [propellers whirring] All the pilots have to do is climb in. And take 'em away. If you're a crew chief, you've got your own P-47. Sometimes you think of it as your personal airplane. The pilots, that fellow you lend it to every day. You let him fly around in it, and you expect him to bring it back... In good condition. No bullet holes, or flak holes. After you've been lending your airplane to one pilot for a long time, You get attached to him, too. If you're a pilot, no matter what your rank, or how many hours you've had, What counts here is the combat flying you've done. Unless you've plenty, you're a beginner. You're called a "sprog." And you remain a sprog until you're wise to the tricks of the trade. After you've put a few missions behind you, you become a "sport." Then, with plenty of action, 50 or 60 missions, If you're still around, you're promoted. You become an "old sport." A veteran. The big shots, like Gil Wymond, are called "wheels." No one knows exactly why. This fellow's a wheel too, says so on his plane. Maj. Richard O. Hunziker, of Tucson, Arizona. Got 179 missions. Your crew chief can't go along, so you always like to tell him what you're gonna do. [Narrator speaking throughout] "Got a triple-threat mission today," "Each section's going after a bridge." "I'll come in on a course of about 40 degrees." "Same old thing. Go out there and dodge around and yak yak..." "Dive bomb out of a left-hand turnabout, then carry the bombs right on down." "We're flying top cover on the other two sections while they bomb," "And then we go in ourselves." "Weather's supposed to be CAVU, so maybe we'll have a good show." All set to go, But you don't. You wait. You wait for five minutes. That's the way it's planned. Time to settle down. Relax. You'll be busy later. So if you've got any thinking to do - and who hasn't? Now is the time to do it. [fanfare crescendos] [engines starting] "Here, hold this til I get back." Takeoff is always rough. Thunderbolt's a heavy airplane. Besides, you've decorated it like a Christmas tree. Belly tank, rockets, guns, 500 pound bombs, cameras. "Hello Breakneck, coleader here. We clear to take the runway for a takeoff? Over." "Roger, coleader from Breakneck. You're clear number 1 to take off." "Roger, Breakneck, thank you." The mile of steel runway will shrink to nothing under you. Halfway down, by the tower, you'll be committed. That means you can't slam on the brakes and stop. Once you're committed, you usually go up. First pair - Wymond and Gustafson. [propeller whirrs] First pair off. Second pair taxis out - Goss and Burgess. Made it okay. Manda and Richardson. Smith and Atwood. C'mon, get her up. Hickok and Morrow. Last pair - Welbes and Hunziker. The squadron is airborne. Over Corsica, then out to sea on the deck. Sixty miles east to Italy. Flying from Corsica, you go only sixty miles, And you're 150 miles behind the German front. Turn again, on that castle. Now you're heading north, into the mountains. Leader section, red section, black section. Formation flying, a game of follow the leader. The squadron leader, he navigates, makes the decisions. Doesn't tell you what to do, does it? You follow, wing tip to wing tip. He turns, you turn. He climbs, you climb. Climbing still, to 10,000, through the clouds. Getting close. Start looking for the target. Stuck down there in one of those ravines. All look alike. Wingman, he's back. Keep the formation spread out. There's a checkpoint, that road. Follow it down to the river. Your first bridge should be down there... somewhere. There it is, pass over it. Come back and attack from the opposite direction - One of the tricks you've learned. Leader section goes into loose-string formation - One plane behind the other. Then, Wymond peels off. The rest of the section follows at 2-second intervals. Last man goes in. No bomb sight in a P-47. Pilot does his own aiming. Bomb bursts from the planes ahead. Couple of misses. Direct hit. Hope your aim is good. Drop your bombs. Pull out. They black you out for a second, blood drains from your head. But you're young, it comes back fast. You're all right now. Leader section re-forms. Top cover. Watches red section bomb. A miss. Another miss. A hit. Black section goes down. Straddle the target. Concussion should do the trick. No more bombs. Still got plenty of gas, plenty of ammo. Go on the prowl. Ease down on the deck. See what you can find. Railroad tracks. Following tracks. Not a bad way to find a train. You spot one, kick her over. Give it a few squirts, might kill somebody. [intermittent gunfire throughout scene] Bust the locomotive first. Train can't move now. Let's see what's in those boxcars. Twelve of you, you'll all criss-cross in. Everybody takes a few passes. Try the cars one at a time. Might be something interesting in them. Usually is. Got a burn nicely now. Take another pass, for luck. [gunfire] [explosion] Strafing spreads the squadron over the sky. Every man his own general. Looks like we're out of trains. Lighthouse out there... wonder if I've got any ammo left? Yep. Radio station... blow out a few tubes. Somebody in that field, don't know who they are... No friends of mine! [gunfire] CRA vehicles parked in that farmyard. More in back. Must be a headquarters. Houses around look kind of suspicious... Might be something in them. Nothing in that one. Nothing in that one. Could be wrong. Nothing in - [explosion] Ah. What do you know. Back at Alto, no one is sweating out 65 Squadron. 66 is taking off. No one will sweat them out either. There are too many missions. Nine for the day. When you don't fly, you've got things to do. Try to make some sort of life for yourself. In trying, you've improvised an American community. Step off the field, you're in Corsica. Step back on, you're in America. This is part of the war too, the endless detail of living. The dust is a problem. Dust is good for the laundry business. Hand laundry. Branches everywhere. Community laundry. Three day service. And, for the rugged individualist, Water supply, Pump, Heating unit, Washing machine. The sergeant used to sell these in New Orleans. He's keeping his hand in. The barber shop. And, for the next customer, always something to read. Never more than a year old. Bus line. Lunch time special. And, for the intellectually-minded, it's time for the more serious things, Like practicing your yo-yo. ♪ ["Yankee Doodle"] ♪ If there's anything you want, don't ask for it. Build it. Build as though you'll be here forever, Knowing you may get orders to move tomorrow. 66 found this canyon, made it their living area. Nobody said they couldn't. Nobody says you can't have a house, build it. Nobody says your squadron can't have a beach club, build one. Nobody says you can't dam up a river, make a swimming hole. This American community has everything. When you come off your shift and somebody else is carrying the ball, You try to relax. Enjoy yourself. In danger a couple hours a day. Rest of the time, you're out of it. Beach club's a busy place. So is the Mediterranean. Mussolini once called it "Mare Nostrum", Our Sea. But that was yesterday. The yachtsman. An old wing tank and a few odds and ends make quite a boat. The crew chiefs scrounge parts. Scrounge is polite for steal. Scrounge them from wrecked Jerry planes, banged-up Italian cars. Old parachutes for sails. They use only the best quality junk. Sometimes when you can get a PX ration of beer, you drink it. Then, you look like this. Alto's the best deal you ever had. "The Country Club", lot of laugh, lot of sun. Your American community has everything... [somber music] Except the things you really want. There are times you'd rather be flying, than waiting around killing time. Guess when you're flying, you don't have that feeling of the day, the week, the month slipping by. Slipping by and leaving you standing still. These are your years, years to get started. Find yourself, your job, profession. Get married, kids, home of your own. These are the years that count. So, you have your picks. To give and receive affection. In return for affection? C-rations, bug powder. As always, in affairs of the heart, Some have peculiar tastes. 66 Squadron heading out. 65 Squadron heading home. A meeting in the air comes and goes fast. 65 leader section, one plane light. When you re-formed after strafing, you noticed it. Nobody saw it happen. Maybe he spun in, maybe he bailed out. You'll think about it later. Now you're waiting for that first sight of home. That's Sirago Air Base. That's Bavenco. You're on your own street. Alto's first turn to the left, three fields down. Keep your formation tight. When you fly over those other outfits, you want to look good. Show them how it's done. Alto. Home. You come in low, and peel up. You peel up to reduce speed. Space the planes 20 seconds apart for landing. Second and third flights go on past the field. They'll circle back when the first flight is down. Drop your gear. Second flight peels up. Third flight'll circle again. This is all the flying the ground crews see. You like to give them a kick. Sometimes you're tired, land them rough. [tires skid] It's embarrassing. The colonel's not happy about the flak holes. New airplane, his crew chief will be mighty sore. And how will you explain this away? Then, after the interrogation, you relax. Grab off some doughnuts and coffee. Jive with the Red Cross girl who meets every mission, And fly the show all over again on the ground. Wymond goes back to work at being a colonel, Missing in Action report to sign. A telegram from the war department has to start somewhere. By mid-April, every rail line in Italy was blocked. We drew a line of interdiction across the country. No train could move south of it. South of it, the railroad system was dead. But the German had to keep the supplies moving. Still had highways. He took to the roads. So we took to the roads. [gunfire] This is what the Germans fear most - You don't blame them. This is the way Rommel got it. He isn't the only one. [gunfire] When you clobber a highway, you burn plenty of ammo. [gunfire] Cyclic rate of fire - 800 rounds a minute. You've got eight guns, 106 bullets a second. Rockets. Those aren't just trucks and Germans. You're stopping ammunition before it's fired on the 5th Army front. And you're doing it 200 miles behind that front. In the weeks that followed, from Corsica to Italy was like a trip to the corner drug store. You could do it in your sleep. We averaged 8-9 missions a day, at the 57th. The French flew about as many. Lafayette Escadrille. The 324 from the 86th over in Italy. The 79th next door. It was good to look up and watch them go by. But there were other things. There were those pillars of smoke. Never knew when you'd see one. That's a wreck. A P-47's cooking, and there's a man in it. With a hit like this, there's nothing to do. Let him burn, and stay clear of the exploding ammo. Keep on landing. You have to. No place to park up there. Why did it happen? Engine cut out for a second, 200 yards from the runway. 200 yards from home. Flight damage might have caused it. You'll never know for sure. All you know is the sum of a war is expensive. You wish that people back home could at least see it. We kept up the pressure. And by the beginning of May, the roads were practically closed. If one man on a motorcycle appeared on a highway by day, He was a dead pigeon. The German took to the sea. Two months after we started, The strangle was on. The Germans had barely enough supplies for two weeks. That's when our ground forces attacked. Allied troops took Cassino. We linked up with a beachhead at Anzio. And in three weeks, we're in Rome. ♪ [fanfare] ♪ The men on the ground pushed north. And as they moved up, they saw what had been done to help them - 10,000 enemy vehicles destroyed or damaged. In every town they took, no marshalling yard. How many German tanks went out of business because of the gasoline these trains never carried? They advanced, and they saw the bridges. How many German shells were never fired because they couldn't get across the rivers? The ground forces exploited their breakthrough. In plain language, they shot and killed Germans. And they ate up the country. Almost 250 miles in one non-stop offensive. The ground forces won a battle, but they still had a war to fight. And you were still flying missions. Up from first light to last light. Only the coming of darkness would stop you. Only the coming of darkness would bring the last missions home to Alto. Then the long work day would end.

Design

As one of the eight original German Type IX submarines, later designated IXA, U-37 had a displacement of 1,032 tonnes (1,016 long tons) when at the surface and 1,153 tonnes (1,135 long tons) while submerged.[5] The U-boat had a total length of 76.50 m (251 ft), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.51 m (21 ft 4 in), a height of 9.40 m (30 ft 10 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[5]

The submarine had a maximum surface speed of 18.2 knots (33.7 km/h; 20.9 mph) and a maximum submerged speed of 7.7 knots (14.3 km/h; 8.9 mph).[5] When submerged, the boat could operate for 65–78 nautical miles (120–144 km; 75–90 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 10,500 nautical miles (19,400 km; 12,100 mi) at 10 knots (19 km/h; 12 mph). U-37 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.[5]

Service history

First patrol

U-37 left Wilhelmshaven, with Kapitänleutnant Heinrich Schuch in command, on 19 August 1939. The boat operated for nearly four weeks in the North Atlantic, returning to port on 15 September 1939.[6]

Second patrol

U-37 left Wilhelmshaven on 5 October 1939 to conduct operations in the North Atlantic now under the command of Korvettenkapitän Werner Hartmann. During this patrol she sank eight ships: four British, two Greek, one French and one Swedish, including the British steam freighter Yorkshire which was traveling with the Allied convoy HG-3, sailing from Gibraltar to Liverpool, England. Hartmann returned his boat to port on 8 November after nearly five weeks at sea.[7]

Third patrol

On 1 January 1940 U-37 was reassigned to the 2nd U-boat Flotilla based at Wilhelmshaven. On 28 January 1940 the U-boat departed for the North Atlantic, with Werner Hartmann in command. As on his previous patrol, Hartmann sank eight ships, this time three British, two Norwegian, one Danish, one French and one Greek. Of these ships, two were in convoy at the time. U-37 returned to Wilhelmshaven on 27 February.[8]

Fourth patrol

U-37 departed Wilhelmshaven on 30 March for Werner Hartmann's third consecutive patrol, this time around Norway. Again, Hartmann proved successful, sinking three ships; the Norwegian Tosca, the Swedish Sveaborg and the British Stancliffe. After patrolling for over two weeks, the U-boat returned to Wilhelmshaven on 18 April.[9]

Fifth patrol

Under a new captain, Kapitänleutnant Victor Oehrn, U-37 departed from Wilhelmshaven on 15 May for a patrol around Portugal and Spain. U-37 had her most successful mission, hitting eleven ships, sinking ten of them. Three French ships were sunk, two Greek, two British, one Swedish, one Argentinian, one Finnish; one British ship was damaged. After three and a half weeks at sea, U-37 returned to Wilhelmshaven on 9 June.[10]

The neutral Argentinian ship was Uruguay, sailing from Rosario to Limerick with a cargo of maize. U-37 surfaced and stopped Uruguay and examined her papers, then sank her with scuttling charges. Her crew of 28 were left in their lifeboats. Fifteen died, 13 survived.[11]

Sixth patrol

U-37 sailed from Wilhelmshaven on 1 August, again with Victor Oehrn in command. This week and a half long patrol in the Atlantic off the west coast of Ireland resulted in the sinking of a single British ship, Upwey Grange. U-37 returned to port on 12 August, but rather than head back to Wilhelmshaven, she made for Lorient in France, where the 2nd U-boat Flotilla was now based.[12]

Seventh patrol

For the first time, U-37 began a patrol from a location other than Germany, in Lorient on 17 August, with Victor Oehrn in command once more. It was to focus on operations off the south-west coast of Ireland. Seven ships were sunk during this voyage; five of which were British, one Norwegian, and one Greek. Of these ships, one was from convoy OA 220, the British Brookwood, traveling from Britain to the Australia, two were from convoy SC 1, the British sloop HMS Penzance (L28) and Blarimore, sailing from Sydney, Nova Scotia, Canada, to the United Kingdom. After two weeks at sea, U-37 returned to Lorient on 30 August.[13]

Eighth patrol

On 24 September, U-37 departed Lorient on Victor Oehrn's fourth patrol, in which he would sail to the North Atlantic. During this month-long operation U-37 sank six ships, four of which were in convoy at the time of attack, all of which were British. Five of these six ships were sailing under the British flag, while the sixth was from Egypt. The British ship Corrientes was sunk as part of OB-217, sailing from Liverpool to North America. Heminge was sailing as part of OB-220, also sailing from Liverpool to North America. British General was sunk while sailing as part of convoy OA 222, sailing from Britain to North America. The fourth ship sunk was the British Stangrant, sailing as part of convoy HX 77 from Halifax to the United Kingdom. The U-boat returned to Lorient on 22 October.[14]

Ninth patrol

After over a month in port, U-37 departed with a new captain, Oberleutnant zur See Asmus Nicolai Clausen on 28 November for operations around north-west Africa and Spain. Seven ships were sunk during this patrol; two French, two Swedish, two British and one Spanish. Of these seven ships, three were in convoy at the time of their sinking. The Swedish Gwalia and Daphne and the British Jeanne M were sailing as part of convoy OG 46 from Britain to Gibraltar. The French vessels, the oiler Rhône and the submarine Sfax belonged to Vichy France and were sunk in error. After five weeks on the high seas, U-37 returned to Lorient on 14 January 1941.[15]

Tenth and eleventh patrols

U-37 left Lorient on 30 January 1941 to patrol off the coast of Portugal. On 8 February she spotted Convoy HG-53. The next day, U-37 sank two British ships, Courland and Estrellano. The third merchant vessel that U-37 sank on her tenth patrol was the British ship Brandenburg, on 10 February. The U-boat then returned to Lorient on 18 February after spending 20 days at sea and sinking 4,781 GRT of shipping.[16]

Leaving Lorient for the final time on 27 February 1941, U-37's last patrol took her to the waters south of Iceland. There she sank two vessels, the Greek cargo ship Mentor on 7 March, and the Icelandic trawler Pétursey on the 12th. After spending 24 days at sea, U-37 entered the port of Kiel on 22 March.[17]

Training boat

On 1 May 1941 U-37 was reassigned to the 26th U-boat Flotilla, based at Pillau (now Baltiysk, Russia) as a training U-boat. She was transferred to the 22nd U-boat Flotilla, based at Gotenhafen (now Gdynia, Poland) on 1 April 1942, and finally to the 4th U-boat Flotilla on 1 July 1944, where she remained until the end of the war.

She was scuttled by her crew on 8 May 1945.[1]

Film Portrayals

The British war propaganda film 49th Parallel (1941) uses the name U-37 for the German submarine whose crew comes ashore in Canada during WW2. The craft is shown being blown up in Hudson Bay. The film was released shortly after the real U-37 was removed from active service.

In the 1943 war film Action in the North Atlantic, the U-boat in the opening scenes is titled U-37.
