It was at that moment that a shell from the shore batteries struck the conning-tower.  Lieutenant Sir John Alleyne and Lieutenant V.A.C.  Crutchley, R.N., were still within; Commander Godsal was close to the tower outside.  Lieutenant Alleyne was stunned by the shock; Lieutenant Crutchley shouted through the slit to the Commander, and, receiving no answer, rang the port engine full speed astern to help in swinging the ship.  By this time she was lying at an angle of about forty degrees to the pier, and seemed to be hard and fast, so that it was impossible to bring her further round.

[Sidenote:  The order is given to abandon ship and the Vindictive sinks in the channel.]

After working the engines for some minutes to no effect, Lieutenant Crutchley gave the order to clear the engine-room and abandon ship, according to the programme previously laid down.  Engineer Lieutenant-Commander Wm. A. Bury, who was the last to leave the engine-room, blew the main charges by the switch installed aft; Lieutenant Crutchley blew the auxiliary charges in the forward six-inch magazine from the conning-tower.  Those on board felt the old ship shrug as the explosive tore the bottom plates and the bulk-heads from her; she sank about six feet and lay upon the bottom of the channel.  Her work was done.

It is to be presumed that Commander Godsal was killed by the shell which struck the conning-tower.  Lieutenant Crutchley, searching the ship before he left her, failed to find his body, or that of Sub-Lieutenant MacLachlan, in that wilderness of splintered wood and shattered steel.  In the previous attempt to block the port, Commander Godsal had commanded Brilliant, and, together with all the officers of that ship and of Sirius, had volunteered at once for a further operation.

Most of the casualties were incurred while the ship was being abandoned.  The men behaved with just that cheery discipline and courage which distinguished them in the Zeebrugge raid.

[Sidenote:  Recall rockets are fired from the flagship.]

Always according to programme, the recall rockets for the small craft were fired from the flagship at 2.30 a.m.  The great red rockets whizzed up to lose themselves in the fog; they cannot have been visible half a mile away; but the work was done, and one by one the launches and motor-boats commenced to appear from the fog, stopped their engines alongside the destroyers and exchanged news with them.  There were wounded men to be transferred and dead men to be reported—­their names called briefly across the water from the little swaying deck to the crowded rail above.  But no one had seen a single enemy craft; the nine German destroyers who were out and free to fight had chosen the discreeter part.

[Sidenote:  Ostend Harbor is thus made impracticable.]

It is not claimed by the officers who carried out the operation that Ostend Harbor is completely blocked; but its purpose—­to embarrass the enemy and make the harbor impracticable to any but small craft and dredging operations difficult—­has been fully accomplished.
