Did your ancestor serve in Britain's Royal Navy during the Second World War? These records document Royal Navy ships that were lost, damaged, or involved in serious incidents during the Second World War, recording events such as sinkings, enemy attacks, collisions, groundings, and mine strikes. Ship casualty logs typically note the vessel’s name, date, location, and cause of the incident, and sometimes include details on the outcome or extent of loss. For family historians, these logs help explain sudden deaths, missing postings, or the end of a ship’s service, while also offering a stark insight into the scale, risk, and human cost of Britain’s wartime naval operations. Created in partnership with the National Museum of the Royal Navy.

British ships in the Second World War
During the Second World War, Britain’s surface fleet was stretched across the globe, protecting trade routes, escorting convoys, engaging enemy warships, and supporting amphibious operations. Battleships, cruisers, destroyers, corvettes, and auxiliary vessels all played vital roles in keeping Britain supplied and projecting naval power from the Atlantic and Arctic to the Mediterranean and Far East. The war at sea was relentless: ships faced constant threats from submarines, aircraft, mines, and surface attack, while harsh weather, long deployments, and mechanical strain added further risks. Losses were heavy, particularly among smaller escort vessels tasked with convoy duty, where danger was frequent and often sudden.
As the war progressed, naval warfare became increasingly industrialised and technologically complex. Radar, sonar, improved gunnery, and better damage-control procedures improved survivability, but they could not eliminate loss. Ships might be sunk in minutes, damaged beyond repair, or survive multiple attacks only to be lost later in the conflict. For the men who served aboard them, ships were not just weapons of war but floating communities, making each sinking a human as well as a strategic tragedy.
Ship Casualty Logs, 1939–1945
Ship casualty logs record the fate of Royal Navy vessels lost or damaged during the Second World War, documenting incidents such as sinkings, severe damage, collisions, groundings, and losses caused by enemy action or accidents. Compiled by naval authorities, these logs typically note the ship’s name, date and cause of the casualty, location, and, in some cases, information about survivors or total loss. For family historians and researchers, casualty logs provide crucial context for understanding how and when a ship was lost, helping to explain sudden deaths, missing service records, or the abrupt end of a naval career, while also illustrating the scale and intensity of Britain’s maritime war.
