The Battle of the Atlantic, Mapped

In the spring of 1941, Britain was in the midst of an Atlantic crisis. German submarine, surface and air attacks were sinking merchant ships by the hundred. If those losses continued, Britain could lose a quarter of its fleet within the year and might just be starved out of the war. Yet, just a few years later, everything had changed. By 1943, German U-boats had gone from predator to prey, as the Allies took full control of Atlantic Ocean. So how did they do it? The Battle of the Atlantic was the longest campaign of the Second World War, running continuously from the first days, right up until the defeat of Nazi Germany 6 years later. In this video, IWM Curator Robert Rumble explores the race to victory in the Atlantic through the lens of war winning technologies, and objects on display at IWM Duxford, and IWM London. *Note* On Occasion this video shows archive footage of captured German submarines flying Allied flags/ensigns Explore and licence the film clips used in this video: https://film.iwmcollections.org.uk/collections/_W90k5g28 Follow IWM on social media: x.com/I_W_M instagram.com/imperialwarmuseums facebook.com/iwm.london Attributions: Bundesarchiv, Bild 146-1980-128-63 / CC-BY-SA 3.0 Bundesarchiv, Bild 146-1976-127-06A / CC-BY-SA 3.0 Bundesarchiv, Bild 101II-MW-3491-06 / Buchheim, Lothar-Günther / CC-BY-SA 3.0 Vector Map of the World: https://freevectormaps.com/world-maps/WRLD-EPS-01-0001?ref=atr https://storymaps.arcgis.com/stories/d0cc437e92884a98966ab6b235143573 https://winstonchurchill.hillsdale.edu/bell-atlantic-battle/ https://uboat.net/allies/merchants/losses_year.html https://uboat.net/fates/losses/chart.htm https://mapsterman.maps.arcgis.com/apps/dashboards/fe88b5e18c6443c7afaf6e32f8432687
