The _Intrepid_ and the _Iphigenia_ came bowling along, sorry for their consort’s ill-luck but anxious only to get on with the immediate task in hand. Lieutenant S. Bonham-Carter beached the _Intrepid_ on the muddy spot marked as her grave, blew a great hole in her side, and was smilingly told by the chief engineer, who had remained below, that the performance was eminently satisfactory. Surely that engineer was the embodiment of dignity and impudence, that peculiar combination that marks the true Briton. Lieutenant E. W. Billyard-Leake, in command of the _Iphigenia_, also entered the canal and carried out his task with splendid efficiency. Both ships were sunk about 200 yards up the fairway. The officers and men of the block-ships were picked up with conspicuous gallantry by perky little motor launches that were all the while subjected to the attention of land batteries as they bustled about their business. Lieutenant Bonham-Carter sent away his boats before leaving the ship, trusting to a Carley float for his own salvation. The calcium flare, which is an integral part of this apparatus, showed him up to the Germans, who kindly turned on a machine-gun for his special benefit. Probably the smoke from his own vessel saved him. He was subsequently picked up by a launch. The most dramatic incident was yet to come. Suddenly the shore end of the mole was lit up by a sheet of livid flame that seemed to sear the sky. C 3, an old submarine commanded by Lieutenant R. D. Sandford, R.N., had been jammed into the great piles that supported the jetty. No ordinary submarine this, but one loaded with several tons of high explosive. Her little crew of heroes got away in a boat before the charge was fired, but not before the craft had been driven right home. The explosion severed the communications of the mole with the shore, a break 60 feet wide being effected. The Germans crowding the wooden structure were blown to bits. The landing parties, working under a galling fire, blew up buildings, destroyed gun-emplacements, and did as much damage as was possible before being recalled. Not a few of the enemy felt the cold steel of British bayonets, and at least two of their guns were captured and turned on them. Fifty minutes elapsed before the siren of the _Vindictive_ sounded for the men to return. The operation against Ostend was not so successful. Owing to the change of wind the _Sirius_ and the _Brilliant_ were revealed by means of the calcium flares lit to guide them, which had previously been hidden by the smoke-cloud. These lights were promptly extinguished by the enemy’s gunners. Unable to find the entrance, the two ships grounded east of the piers, and were there sunk.
