The Battle of Jutland, fought in 1916 between the British Grand Fleet and Germany's High Seas Fleet, stands as the largest naval clash of the First World War, and the costliest for Britain, which lost more ships and more men than the Germans did. This film reexamines that lopsided casualty count, tracing it to outdated Royal Navy gunnery tactics and design flaws in British battlecruisers that made them prone to catastrophic explosions. Shipwreck footage from the seabed graves of vessels like HMS Indefatigable and HMS Queen Mary anchors the analysis, alongside archival photographs and maps that lay out the fleet movements hour by hour. Naval historians walk through why, despite the losses, the battle left the German fleet bottled up in port for the rest of the war, unable to challenge British control of the North Sea. The argument built here is that tactical defeat and strategic victory are not the same thing, and that Jutland's real outcome took years to become clear.
