But the flagship at the head of the line was not so alert; the death of the Admiral was at this critical moment severely felt, and the _Polyphemus_, though she eluded three torpedoes which were fired at her at about 3000 yards by the German battleships, found two torpedo boats closing in upon her from right ahead. She charged one with the ram; there was no time for thinking, and she caught the boat fair under her steel prow, which cut through the thin plating of the boat like a knife through matchwood. Her huge hull passed with a slight shudder over the boat, which instantly foundered with a violent explosion. The other boat, however, passed her only a hundred yards away in the spray of shells and projectiles which seemed as if by enchantment just to miss it. Her crew had a vision of wild-looking officers and men busy at the boat’s torpedo tubes; the flash of two torpedoes glinted in the sun as they leaped from the tubes into the water; then a great shell caught the boat and sent her reeling and sinking, but too late. The mischief had been done. One of the German torpedoes struck the _Polyphemus_ full on the starboard engine-room, and, exploding with devastating effect, blew in the side and bulkheads. The engine-room filled at once, and bereft of half her power the great cruiser broke from the British line and headed for the shore with a heavy list. Almost at the same moment the fire on board the _Caprivi_ blazed up so fiercely under the impact of the British shells that she, too, had to leave the line of battle. The British line re-formed, heading east, now only four ships strong, faced by eight German ships. For some minutes both fleets steamed on a parallel course 4500 yards apart, the Germans, who had, on the whole, suffered less damage, since their injuries were distributed over a larger number of ships, steaming a little faster. Once more the German Admiral essayed a surprise. Suddenly the eight German ships made each simultaneously a quarter-turn, which brought them into line abreast. They stood in towards the four British survivors, to deal the culminating blow. End-on they caught the full vehemence of the British fire. But with forces so weakened, the British senior officer could not run the risk of a mêlée, and to avoid his antagonists he, too, turned away from the Germans in a line abreast, and at the same moment the _Achates_, _Imperieuse_, and _Aurora_ fired their stern torpedo tubes. Realising the danger of pressing too closely in the course of a retiring fleet, the Germans again altered course to line ahead, and steered to cut the British ships off from their line of retreat up the Forth.
