“Bang, bang, bang, bang, bang!”

Then the Boche woke up. Two canisters rose, streamed, and fell, dropping slightly to my right.

But still our trench-mortars went on. Two more canisters tried for Davidson’s gun.

I was elated. “This for Thompson and Robertson,” I said, as our footballs went on methodically.

Then the whizz-bangs began on Trafalgar Square.

I went to the telephone.

“Artillery,” I said briefly. “Retaliate C 1 Sector.”

And then our guns began.

“Scream, scream, scream” they went over.

“Swish—swish” answered the Boche whizz-bangs.
