In 1941 the Allies determined the war would need to be won in the Atlantic.1 From 1939 to 1945 the Battle of the Atlantic was the longest continuous military campaign in World War II. It stemmed from the start of the war in Europe with Hitler’s invasion of Poland on September 1, 1939, and the declaration of war by France and Britain on the Third Reich. This was followed by the Battle of Britain and Fall of France in 1940 and the Allies’ declaration of war on Italy on June 10, 1941. The United States, as a non-belligerent and working through its neutrality laws, aided the Allies, namely Britain, through cash and carry and lend-lease purchases of large amounts of American-made armaments as well as providing reconnaissance to the British navy and air force who were in the fight against German U-boats and battleships aggressively attacking and sinking the merchant ships headed for Britain.

A massive nearly square-shaped zone of conflict surrounded Great Britain and Iceland with its approximate boundaries from the southeast coast of Greenland across the Atlantic to France and north between Britain and Norway and back around Iceland towards Greenland. Since Denmark was occupied by German forces, the United States in April 1941 occupied their abandoned colony of Greenland and designated it as part of the Western hemisphere to categorize American non-belligerent military activity as self-defense. The Americans took the same approach with Iceland sending troops as a forward, if ostensibly defensive, posture.2
This situation brought the navies of the United States, Canada and Great Britain together as the Allies provided escort to the merchant ships into a combat zone with the German Kriegsmarine (navy), specifically U-boats (submarines) and warships, as well as the Luftwaffe (air force), who were severely disrupting the supply line. The commanders of the opposing forces were both World War I veterans. Vice-Admiral Gilbert O. Stephenson (1878-1972), a pioneer of anti-submarine techniques in the First World War, was training commander of the British escort groups while Admiral Karl Dönitz (1891-1980), whose navy career began before the Great War was the commander of the German U-boat fleet.


Until the attack on Pearl Harbor by Japan on December 7, 1941 the United States was a non-belligerent and Hitler wanted to keep it that way. Germany was mounting its invasion of Russia called Operation Barbarossa, which, involving almost 4 million troops, was the largest offensive operation in military history. For American internationalists looking for a way into the war in 1941, American neutrality and Lend-Lease laws along with public opinion complicated that desire. American opinion, markedly isolationist through the 1930’s and into the early 1940’s, was, in spring and summer 1941, split on whether the U.S. should escort merchant marine vessels while a large majority was against entering the war. Most Americans polled believed the United States had already been doing too much for Britain.3 In April 1941, after a year of the largest armament production program in U.S. history, President Roosevelt decided for American patrols comprised of ships and airplanes, rather than escorts or convoys, to insure the delivery of needed supplies to Britain and other Allied combatants. The mission, started without diplomatic or public fanfare, gave solely reconnaissance aid to Britain. This role in an expanding territory in the Atlantic was justified by FDR as hemispheric self-defense from the Nazis. This position was reinforced by Roosevelt in a fireside chat with the American people on May 27, 1941. By then the Bismarck was under attack and sunk. FDR’s rationale was based on the premise that the “supreme purpose” of the Axis powers was to achieve world domination by its control of the high seas and the capture of Great Britain was key to that endeavor.4

In the face of these American patrols that FDR spoke of, Hitler was, after the fall of Denmark, Norway, the Low Countries, and France, looking east. The Germans were on the offensive from Yugoslavia to Greece to North Africa. Though the invasion of Britain was off, the Atlantic remained under siege. In April and May 1941 German wolfpacks (coordinated attacks by U-boats on convoys) took a heavy toll on British merchant shipping in the combat zone south of Iceland.5
May 24, 1941.
On May 24, 1941, the German battleship Bismarck, accompanied by the cruiser Prinz Eugen, left Norway for the Atlantic. The British intercepted the German ships in the Denmark Strait between Greenland and Iceland, but the Bismarck fought back and sank the HMS Hood, the biggest battlecruiser in the world at that time, which exploded with the loss of 1,415 of its crew. The sinking of the Hood marked what remains the single greatest loss of life in Royal Navy history.
The battle also damaged the Prince of Wales. The Bismarck, under the command of Günther Lütjens (1887-1941), continued its passage south to the convoy routes but had sustained battle damage to its fuel tanks which led to subsequent flooding. Pursued by the damaged Prince of Wales and cruisers Norfolk and Suffolk, the Bismarck, traveling more slowly and trailing oil, changed course to head to Brest for ship repairs. In short order, the Bismarck turned on the British pursuers to allow the Prinz Eugen to escape into the Atlantic.


That evening, Fairey Swordfish planes — a resilient British torpedo bomber biplane that originated in the early 1930s —took off from the Home Fleet’s aircraft carrier Victorious for its first attack on the Bismarck. They engaged the warship but without important effect. For the next 31 hours, since the sinking of the Hood, the Bismarck eluded the English fleet which was looking for it further to the west.

May 25, 1941.
Commander Lütjens was not aware that the British had lost him. In the early hours of May 25, 1941, he broke radio silence to send a coded message to Germany. Though its content was indecipherable, the British heard it and observed that the German commander had stopped communicating with Wilhelmhaven in Germany and began talking with Paris. This was a break that allowed the British to figure closely the actual vicinity of the enemy warship and that it was heading to France. British warships in search of the Bismarck were provided the new coordinates and the orders to pursue accordingly. This included King George V and Norfolk to be joined by a flotilla of 5 destroyers under the command of Captain Philip Vian (1894-1968).

May 26, 1941.
At 10 a.m. the Bismarck was spotted by an American pilot in one of the American-made Catalinas provided by Roosevelt to the British war effort. Flying out of a base in Northern Ireland, the plane was part of a squadron that had been assigned a specific search area for the Bismarck. It was piloted by American Ensign Leonard “Tuck” Smith (1915-2006) whose role was to familiarize RAF Pilot Officer, Dennis Briggs, with the plane’s controls. Though revealed long after the war’s end, Smith was credited with being the first person to spot the Bismarck before the final battle. He was awarded the Navy’s Distinguished Flying Cross for his role in the sinking of the Bismarck. Leaving in the middle of the night on May 26, 1941, the weather was bad with a ceiling of about 100 feet. According to Smith’s report, it took six hours to reach the search area. As soon as they spotted the Bismarck, they came under intense anti-aircraft fire from the warship and Smith had to take violent evasive action to escape getting blown out of the sky. Smith and the crew soon lost contact with the battleship, but their messages as to its precise location had been received. British ships and planes soon converged on an intercept course. Already the aircraft carrier Ark Royal had sent scouting planes and a pair of Swordfish spotted the enemy warship shortly after Smith did. When Smith landed his Catalina back in Northern Ireland at 9: 30 p.m., 18 hours after having taken off, it would be just 12 more hours that the 35,000-ton Bismarck would be at the bottom of the Atlantic Ocean.
After the Bismarck’s location was known, Captain Philip Vian’s flotilla that was to join King George V in the search for Bismarck, changed course and headed directly for the Bismarck. Three days earlier, on May 23, 1941, the British naval formation known as Force H had left Gibraltar for convoy duties that included the aircraft carrier HMS Ark Royal, battlecruiser Renown, and light cruiser Sheffield. On May 26, 1941, Force H set course to intercept the Bismarck.
Starting late on Monday, May 26, 1941, the last battle of the German battleship Bismarck started in the Atlantic Ocean The ship was sunk about 350 miles west of the port city of Brest in France. At 2:50 p.m. on May 26, 1941, fifteen Fairey Swordfish planes took off from the aircraft carrier HMS Ark Royal to attack the Bismarck.

The attack failed and the British cruiser Sheffield fell under friendly fire. The British staked everything on one more attack to stop the Bismarck before it could safely enter into Brest harbor the next day. At 7:10 p.m., a second sortie of 15 Swordfish planes took off from the HMS Ark Royal armed with conventional torpedoes. At 8:47 p.m., these Swordfish began their attack. The Bismarck received a direct hit but it was not mortal. A second torpedo hit the ship’s stern that jammed and disabled the battleship’s rudders crippling it. The King George V and HMS Rodney joined the fray from the northwest about 6.00 p.m. and, at 10:00 p.m., the Sheffield directed Captain Vian’s destroyers towards the target where they harassed an unmaneuverable Bismarck with torpedo attacks through the night.

May 27, 1941.
The next day, Tuesday, May 27, 1941, the Bismarck, unable to steer or repair the rudder, expected an attack from the British battleships. At 8:30 a.m., they readied battle stations. At 8:43 a.m. the HMS Rodney and HMS King George V, joined by cruisers and destroyers, including the HMS Norfolk and HMS Dorsetshire, spotted the Bismarck. At 8:47 a.m., from a distance of over 10 miles, the battleship HMS Rodney opened fire commencing the final battle. Though Bismarck returned fire, with its disabled rudder, its gun platforms were unstable due to uncontrollable movements on a rising sea in gale-force winds. At two minutes past 9 a.m. the HMS Rodney unloaded its 16-inch guns and hit the Bismarck’s forward superstructure, severely damaging the bridge, command facilities, fire control, and observation posts, as well as killing most of the warship’s senior officers. Both HMS Rodney and HMS King George V engaged Bismarck in heavy gunfire with increasing precision as British shells dismantled the ship’s command structure and gun turrets making the Bismarck a floating hulk. With Bismarck’s ability to return fire random and infrequent the British warships came into closer range for the German warship’s final neutralization. HMS Norfolk and HMS Dorsetshire joined HMS Rodney to fire on Bismarck with its 8 -inch guns and torpedoes. With its four main gun turrets inoperable, at 9.31 a.m., the Bismarck had lost the capacity to fight back with orders down the chain of German officers to scuttle and abandon the ship.
Nearly 3,000 projectiles were used against the Bismarck to achieve this outcome in the final battle. In the final stages of the battle the British ships surrounded the Bismarck in a crossfire that overpowered the German crew. In addition to significant structural damage, this intense continuous British gunfire set off fires on the Bismarck that caused secondary explosions.

The British kept firing, the HMS Rodney at point-blank range and the King George V from a greater distance to lob in shells. At 10:05 a.m., the Bismarck was sunk. In the battle’s last stage, the British torpedoes tore holes in the Bismarck’s hull hastening the ship’s decline into the sea. Of the Bismarck’s crew of 2, 200 men only 114 survived. The Luftwaffe that the Bismarck hoped would intervene was not able to fly in meaningful number due to bad weather. The British left the rescue mission with hundreds of German sailors still in the water as a German U-boat periscope had been spotted.

After the sinking, Admiral John Tovey (1885-1971) said: “The Bismarck had put up a most gallant fight against impossible odds worthy of the old days of the Imperial German Navy, and she went down with her colours flying.”6
