The Laconia incident was a series of events surrounding the sinking of a British passenger ship in the Atlantic Ocean on 12 September 1942, during World War II, and a subsequent aerial attack on German and Italian submarines involved in rescue attempts. RMS Laconia, carrying 2,732 crew, passengers, soldiers, and prisoners of war, was torpedoed and sunk by U-156, a German U-boat, off the West African coast. Operating partly under the dictates of the old prize rules, the U-boat's commander, Korvettenkapitän Werner Hartenstein, immediately commenced rescue operations. U-156 broadcast her position on open radio channels to all Allied powers nearby, and was joined by the crews of several other U-boats in the vicinity.
The second RMS Laconia was a Cunard ocean liner, built by Swan, Hunter & Wigham Richardson as a successor of the 1911–1917 Laconia. The new ship was launched on 9 April 1921, and made her maiden voyage on 25 May 1922 from Southampton to New York City. At the outbreak of the Second World War she was converted into an armed merchant cruiser, and later a troopship. Like her predecessor, sunk during the First World War, this Laconia was also destroyed by a German submarine. Some estimates of the death toll have suggested that over 1,658 people were killed when the Laconia sank. The U-boat commander Werner Hartenstein then staged a dramatic effort to rescue the passengers and the crew of Laconia, which involved additional German U-boats and became known as the Laconia incident.
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, knockdown, loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast.
German submarine U-69 was the first Type VIIC U-boat of the German Navy (Kriegsmarine) during World War II. This meant that compared to previous U-boats, she could travel further afield for longer, with a payload of fourteen torpedoes, an 8.8 cm (3.5 in) deck gun for smaller vessels and a flak gun for use against aircraft. U-69 was very successful, sinking over 72,000 gross register tons (GRT) of Allied shipping in a career lasting two years, making her one of the longest surviving, continuously serving, U-boats. Her most notable attack was on the civilian ferry SS Caribou, which sank off the coast of Newfoundland in October 1942, killing 137 men, women and children. She was rammed and sunk by HMS Fame on 17 February 1943.
German submarine U-48 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II, and the most successful that was commissioned. During her two years of active service, U-48 sank 51 ships for a total of 299,477 GRT and 1,060 tons; she also damaged four more for a total of 27,877 GRT over twelve war patrols conducted during the opening stages of the Battle of the Atlantic.
German submarine U-96 was a Type VIIC U-boat of the German Navy (Kriegsmarine) during World War II. Her keel was laid down on 16 September 1939, by Germaniawerft, of Kiel as yard number 601. She was commissioned on 14 September 1940, with Kapitänleutnant Heinrich Lehmann-Willenbrock in command. Lehmann-Willenbrock was relieved in March 1942 by Oberleutnant zur See Hans-Jürgen Hellriegel, who was relieved in turn in March 1943 by Oblt.z.S. Wilhelm Peters. In February 1944, Oblt.z.S. Horst Willner took command, turning the boat over to Oblt.z.S. Robert Rix in June of that year. Rix commanded the boat until 15 February 1945.

MV C.O. Stillman was an oil tanker that was built by a German shipyard in 1928 for a Canadian-based shipping company. A Panamanian subsidiary of Esso bought her at the end of 1936 and she was sunk by the German submarine U-68 in the Caribbean on June 4, 1942 about 41 nautical miles (76 km) southwest of Isla de Mona, Puerto Rico.

Merchant seamen crewed the ships of the British Merchant Navy which kept the United Kingdom supplied with raw materials, arms, ammunition, fuel, food and all of the necessities of a nation at war throughout World War II — literally enabling the country to defend itself. In doing this, they sustained a considerably greater casualty rate than almost every other branch of the armed services and suffered great hardship. Seamen were aged from fourteen through to their late seventies.
