"The cyclone cellar!" some one said. "We will come here during the return fire."

But one look down the crude steps decided me to brave the return fire and die in the open. The cave below the flat roof, turf-covered against the keen eyes of aeroplanes, was full of water. The officers watched my expression and smiled.

And now we had reached the battery, and eager gunners were tearing away the trees and shrubbery that covered them. In an incredible space of time the great grey guns, sinister, potential of death, lay open to the bright sky. The crews gathered round, each man to his place. The shell was pushed home, the gunners held the lanyards.

"Open your mouth wide," said the officer in charge, and gave the signal.

The great steel throats were torn open. The monsters recoiled, as if aghast at what they had done. Their white smoke curled from the muzzles. The dull horses in the road lifted their heads.

And over there, beyond the line of poplar trees, what?

One by one they fired the great guns. Then all together, several rounds. The air was torn with noise. Other batteries, far and near, took up the echo. The lassitude of the deadlock was broken.

And then overhead the bursting shell of a German gun. The return fire had commenced!

I had been under fire before. The sound of a bursting shell was not a new one. But there had always before been a strong element of chance in my favour. When the Germans were shelling a town, who was I that a shell should pick me out to fall on or to explode near? But this was different. They were firing at a battery, and I was beside that battery. It was all very well for the officer in charge to have said they had never located his battery. I did not believe him. I still doubt him. For another shell came.

The soldiers from the farmhouse had gathered behind us in the field. I turned and looked at them. They were smiling. So I summoned a shaky smile myself and refused the hospitality of the cellar full of water.
