_Intrepid_, smoking like a volcano and with all her guns blazing, followed; her motor launch had failed to get alongside outside the harbor, and she had men enough for anything. Straight into the canal she steered, her smoke blowing back from her into _Iphigenia's_ eyes, so that the latter, blinded and going a little wild, rammed a dredger with a barge moored beside it, which lay at the western arm of the canal. She got clear though, and entered the canal pushing the barge before her. It was then that a shell hit the steam connections of her whistle, and the escape of steam which followed drove off some of the smoke and let her see what she was doing. [Sidenote: Sinking of the _Intrepid_ and the _Iphigenia_.] Lieutenant Stuart Bonham-Carter, commanding the _Intrepid_, placed the nose of his ship neatly on the mud of the western bank, ordered his crew away, and blew up his ship by the switches in the chart-room. Four dull bumps was all that could be heard; and immediately afterwards there arrived on deck the engineer, who had been in the engine-room during the explosion and reported that all was as it should be. [Sidenote: Probable that the canal is effectively blocked.] Lieutenant E.W. Billyard-Leake, commanding _Iphigenia_, beached her according to arrangement on the eastern side, blew her up, saw her drop nicely across the canal, and left her with her engines still going to hold her in position till she should have bedded well down on the bottom. According to latest reports from air observation, the two old ships with their holds full of concrete are lying across the canal in a V position; and it is probable that the work they set out to do has been accomplished and that the canal is effectively blocked. A motor launch, under Lieutenant P.T. Deane, R.N.V.R., had followed them in to bring away the crews, and waited further up the canal towards the mouth against the western bank. Lieutenant Bonham-Carter, having sent away his boats, was reduced to a Carley float, an apparatus like an exaggerated lifebuoy with a floor of grating. Upon contact with the water it ignited a calcium flare, and he was adrift in the uncanny illumination with a German machine-gun a few hundred yards away giving him its undivided attention. What saved him was possibly the fact that the defunct _Intrepid_ was still emitting huge clouds of smoke, which it had been worth nobody's while to turn off. He managed to catch a rope as the motor launch started, and was towed for a while till he was observed and taken on board. Another officer jumped ashore and ran along the bank to the launch. A bullet from the machine-gun stung him as he ran, and when he arrived, charging down the bank out of the dark, he was received by a number of the launch's crew who attacked him with a hammer.
