We were rolling in a grey sea, churned by the monster's dying struggles. It was a desolate waste, patched with horror. Far away, on the port bow, something small and blurred was showing. It was either smoke or the hull of a big ship.

"The first transport!" Bernard said. "We had better be ..."

He did not finish his sentence. Something shrieked overhead like an invisible express train. There was a sound like a clap of thunder, and a fountain of spray rose a hundred yards away from us.

We wheeled round. Not quarter of a mile away, and heading straight for us, we saw two immense, white ostrich feathers, divided as by the blade of a knife. Each instant they grew larger.

One of the convoying destroyers had made a grand detour and was coming for us at the charge.

Then, I cannot say when or how, there was a sound like two great hands clapping together in the air above us. Instantaneously, the plates of the deck and conning-tower rang like gongs, followed by little splashing sounds, as if someone was throwing eggs.

I had no idea what it was. "What the devil ..." I was beginning, when Bernard explained.

"Shrapnel," he said, and held out his left arm to me. It ended in what looked like a bundle of crimson rags.

"Damn the blighters!" he said, "they've blown off my left hand. Quick, John, or we shall lose the trick. Your handkerchief!"

I pulled it out mechanically.
