5th April 1942, the fleets of Admiral Nagumo and Admiral Somerville nearly found each other. Two Albacores made contact with the japanese fleet, consisting of the Kido Butai (except Kaga) and all four Kongo-Class battleships. Somerville's fleet (2 modern aircraft carriers, Warspite and all 4 Revenge-Class battleships) had japanese planes several times on the radar screens. Churchill later described it as the most dangerous moment of the war. It is an almost forgotten episode of the war. But what would have happened if the fleets meet each other? Did Somerville really want to attack the japanese fleet? Why did the IJN abandon plans to conquer Ceylon?
