At 5.56 Beatty sighted Jellicoe's battleships at five miles' distance on his port bow. His task was now to cross the front of the German line, head it off east and southwards, and afford Jellicoe room for deployment between Beatty himself and Evan-Thomas. For reasons of tactics and prudence Jellicoe deployed on his port wing, i.e., towards the east, This took him away from the Germans, but tended to cut them off from their base. The deployment was skilfully executed, though Admiral Hood and his battle-cruiser the Invincible, while taking position in front of Beatty, suffered the fate of the Queen Mary and Indefatigable; and the British Fleet soon formed a single line curving round east and south-eastwards like a net into which the Germans were being drawn. The crisis had arrived, and German naval power seemed on the verge of extinction. But the weather came to assist Von Scheer's tactical skill. He turned with less misfortune than had attended Beatty's similar manoeuvre two hours earlier, and set himself to fight a magnificent rearguard action and extricate his fleet as best he could. Fortunately for him the visibility grew steadily worse, and with it the range of fire diminished. This deprived Jellicoe of the advantage of his heavier guns, and indeed reduced the range of gun-fire to that of torpedoes. Here Von Scheer discovered his chance, and it was upon torpedo attacks that he relied for the defence of his fleet. Jellicoe, with his superior speed, could have closed had he deemed it wise. But he thought of what hung on the fate of the fleet he commanded, and shrank from exposing his battleships to the risk of torpedo destruction. His dilemma was acute: gun-fire was very effective at 18,000 yards, the torpedo began to be so at 10,000. Our cue was to fight between the two; but low visibility hid the German ships outside torpedo range, while within it fifty lucky German torpedoes might have sent every British Dreadnought to the bottom and decided the war in Germany's favour. On the other hand, we might have sunk every German ship and conceivably ended the war in 1917. War is an experimental science; but this experiment was never made, and no one can say what the result would have been if it had. Beatty wished to make it, Jellicoe refrained.
