History of the Second World War

While the land campaign in Greece was grinding forward, the Mediterranean was the scene of an equally consequential struggle at sea. This episode tells the story of the Battle of Cape Matapan, one of the most decisive British naval victories of the entire war. When the Italian fleet sortied to intercept a British convoy carrying New Zealand troops to Greece, the Royal Navy was waiting — thanks in no small part to the codebreakers at Bletchley Park, where a young woman named Mavis Lever had cracked the Italian Enigma by exploiting a careless operator's mistake. What followed was a night action in which British battleships, guided by radar that the Italians did not possess, caught two heavy cruisers at point-blank range and annihilated them in minutes, sinking three cruisers and two destroyers and killing over 2,300 Italian sailors while suffering almost no losses themselves — a stunning demonstration of how technology and intelligence were reshaping naval warfare.

As the spring of 1941 approaches, the war in Greece enters a critical new phase. The Italians launch a major offensive in Albania, staking everything on capturing the heavily defended Hill 731, only to suffer over 12,000 casualties and gain essentially nothing after weeks of futile assaults. Meanwhile, Bulgaria's decision to join the Tripartite Pact and allow German troops to cross its territory fundamentally changes the strategic picture, opening vast stretches of border to a potential German invasion. On the Allied side, the British and Greeks struggle to agree on where to make their stand, ultimately settling on the shorter Aliákmon Line over Greek objections, while tens of thousands of Australian and New Zealand troops begin arriving in Greece to man defenses that are far from complete — setting the stage for the looming German onslaught.

The Italo-Greek War, which began as a purely regional conflict in October 1940, would transform into a broader European confrontation as both Germany and Britain made the fateful decision to intervene in Greece. For the Germans, concerns about protecting vital Romanian oil fields from potential British air attacks, combined with fears of Italian collapse, drove the planning of Operation Marita, an invasion designed to secure the Balkans before the launch of Barbarossa. Meanwhile, Churchill and the British leadership saw Greece as an opportunity to distract Axis forces, demonstrate support for smaller nations, and potentially build a Balkan alliance with Yugoslavia and Turkey. Greek leader Metaxas initially resisted British ground forces, fearing they would provoke German intervention, but his death in January 1941 led to a shift in policy under his successor. As German forces moved into Romania and Bulgaria throughout early 1941, and British RAF squadrons began arriving in Greece, both sides prepared for a confrontation that would expand the war far beyond the mountains of Albania where Italian and Greek forces had been locked in bitter combat.
