Information had been received that a new type of Zeppelin had been constructed, a "mother" type, capable of carrying a number of aeroplanes.

The intention of the operation order was to destroy all known Zeppelin sheds; each air squadron supplying special officers for the purpose.

I well remember the particulars of that order. They printed their details upon my memory because I had been selected to destroy the sheds at Saarbruck. I was to leave three hours before the following dawn.

I remember Nap's disappointment that I was to go alone. He helped my machine out without a word. He may have had a premonition that I was not to return as I watched him silently fixing the compass and map-roller, testing the spring catch and guide of the bomb-dropper and packing into it its heavy load of "cough-drops." Then he stood like a dumb figure waiting for my starting signal.

"Buck up, Nap," I ventured, climbing into the seat. "One would think this was a funeral. I must get a hustle on as I've got to do 120 miles before I can get to business, so if everything's right, I'll swoop up."

Nap looked up.

"Fly high, and good luck," was all he said as he gripped my hand. Then I pressed the starter, the propeller hummed and pulled me into the star-specked sky.

I steered easterly, leaving on my left the red fire-glow of Rheims and passing over the sleepy lights of Valny. Within an hour I was over the great black stretch of the Argonne Forest, and crossing the Meuse, a long line of fog with Verdun 7000 feet below. The engine was working well, throwing back the miles at about 60 per hour. A glow of lights to the right showed Metz next to a streak of grey, the Moselle River; and as the dawn-light came into the sky, the Saar River came under me, covered by a fog with a fringe that flapped over its right bank and covered Saarbruck.

According to the sketch-map the Zeppelin sheds were near the railway station. So I flew low into the mist to get their correct position. The noise of my engine brought a shot from an aerial gun, but the fog saved me. A bunch of lights brought the station into view with the unmistakable long hangar of the Zeppelin adjacent to it.

I turned to get the sheds beneath me, and three foot-treads sent as many bombs chasing each other earthwards.
