Warned by wireless telegraphy that destroyers had been sighted, the British crews were on the _qui vive_. There was not time at this eleventh hour to weigh and put out to sea; the only possible course was to meet the attack at anchorage. The fleet was anchored off Rosyth, the battleships in two lines ahead, headed by the flagships _Vanguard_ and _Captain_. The _Vanguard_ and _Captain_, the leading ships in the starboard and port lines respectively, were just abreast of the Beamer Rock and Port Edgar. The seven armoured cruisers were moored in the St. Margaret’s Hope Anchorage. To torpedo craft coming from the sea and passing under the Forth Bridge, the fleet thus offered a narrow front, and comparatively few of its guns would bear. About 2.30 a.m. on Sunday morning, the lookout of the _Vanguard_ detected white foam, as from the bows of a destroyer, just under Battery Point; a few seconds later, the same sign was seen to the south of Inchgarvie, and as the bugles sounded and the 12-in. guns in the three forward turrets of the British flagship opened, and the searchlights played their steady glare upon the dark waters just under the Forth Bridge, the forms of destroyers or torpedo boats fast approaching were unmistakably seen. In a moment the air trembled with the concussion of heavy guns; the quick-firers of the fleet opened a terrific fire; and straight at the battleships came eighteen German destroyers and large torpedo boats, keeping perfect station, at impetuous speed. The sea boiled about them; the night seemed ablaze with the flashing of the great guns and the brilliant flame of exploding shells. Now one destroyer careened and disappeared; now another flew into splinters, as the gunners sent home their huge projectiles. Above all the din and tumult could be heard the rapid hammering of the pom-poms, as they beat from the bridges with their steady stream of projectiles upon the approaching craft. Four destroyers went to the bottom in that furious onrush; ten entered the British lines, and passed down them with the great ships on either side, not more than 200 yards away, and every gun depressed as much as it could be, vomiting flame and steel upon the enemy; the others turned back. The thud of torpedo firing followed; but the boats amid that tempest of projectiles, with the blinding glare of the searchlights in their gunners’ eyes, aimed uncertainly. Clear and unforgettable the figures of officers and men stood out of the blackness, as the searchlights caught the boats. Some could be seen heaving heavy weights overboard; others were busy at the torpedo tubes; but in the blaze of light the pom-poms mowed them down, and tore the upper works of the destroyers to flinders. Funnels were cut off and vanished into space; a conning-tower was blown visibly away by a 12-in. shell which caught it fairly, and as the smitten boat sank there was a series of terrific explosions.
