Standing by my side, the lookout seemed to await a sign from the captain.

As for him, he did not even turn his head; and I shall never forget the expression of disdain imprinted on his visage.
At this moment, I was pushed suddenly toward the hatchway of my cabin, which was fastened above me.

At the same instant the other hatchways were closed; the deck became watertight.

I heard a single throb of the machinery, and the plunge was made, the submarine disappeared beneath the waters of the lake.
Cannon shot still boomed above us.

Their heavy echo reached my ear; then everything was peace.
