At the sound of the guns I felt that I was moving in natural air once more.

I felt that I was coming home.
We were stopped at a long line of ramparts, and a German sergeant stared at us till he saw the lieutenant beside me, when he saluted and we passed on.

Almost at once we dipped into narrow twisting streets, choked with soldiers, where it was hard business to steer.

There were few lights--only now and then the flare of a torch which showed the grey stone houses, with every window latticed and shuttered.

I had put out my headlights and had only side lamps, so we had to pick our way gingerly through the labyrinth.
