Strategic control versus tactical opportunity

Jellicoe's information-led judgment and the fleet's training created the two opportunities to cross the German T. That same method told him to turn away from torpedoes rather than accept predictable losses for a chance at a more decisive tactical result. His minimum strategic requirement was to retain command of the sea: as long as the Grand Fleet survived, Britain could maintain the blockade and prevent a German surface blockade in return. Destruction of the High Seas Fleet would likewise have opened the Baltic to British pressure against Germany's remaining supply routes, so both battle fleets carried consequences far beyond the ships themselves. This was the central tradeoff in Jellicoe's command: preserving the instrument that guaranteed strategic success made him less willing to gamble it for tactical annihilation.
