"Bratby!" shouted Snorty, giving the despatch-rider his full name for once, as he saw the two doubling up.

"Yes, sir," came the answer smartly.

"You know the observing officer's dug-out near Ginchy?"

"The place where I carried the despatches the other day, sir?"

"Exactly."

"Yes, sir, I know it."

"Good! Go there at once. The wires are snapped again, and we have received a broken message through which stopped in the middle. One of our 'planes has come down. It must be part of 'B' Flight, for they're not in yet. Go there at once, take this message to the officer or senior N.C.O. in charge, and get the full message from him. Learn what you can while you are there, and come back at once, so that we may send out a breakdown gang for the machine, if not too late."

"Right, sir."

"Mind, we want the exact location of the machine, and you must try to find out if it is a bad crash, and what has become of the pilot and observer."

"Yes, sir."
