Captain Blaikie looks grave.

"Better ring up the Gunners, I think. Where are the shells coming from?"

"That wood on our left front, I think."

"That's P 27. Telephone orderly, there?"

A figure appears in the doorway.

"Yes, sirr."

"Ring up Major Cavanagh, and say that H 21 is being shelled from P 27. Retaliate!"

"Verra good, sirr."

The telephone orderly disappears, to return in five minutes.

"Major Cavanagh's compliments, sirr, and he is coming up himself for tae observe from the firing trench."
