good deal of impetus being given to it
by some light German field-guns which commenced to scatter
high-explosive shrapnel over the open ground.

The shooting, fortunately, was not very accurate, no doubt because, by
the light of the flares, it was difficult for the German observers to
direct their fire. But the hint was enough for the Tearaways, and they
knew that daybreak would bring more accurate and more constant
artillery fire upon the new position.

The British gunners had been warned not to open fire unless called
upon, because a working party was in the open; but now the batteries
were telephoned to with a request for shrapnel on the German parapets
to keep down some of the heavy rifle fire.

Since the gunners had already registered the target of the German
trench, their fire was just as accurate by night as it would be by day,
and shell after shell burst over the German parapet, sweeping their
trench with showers of shrapnel.

While all this was going on the men at the listening-post had tackled
the job of driving their sap out to the German General. This work was
done in a different fashion from the digging of the new trench.

The listening-post was merely a pit in the ground, originally a large
shell crater, and deepened and widened until it was sufficiently large
to hold half-a-dozen men. At one side of the pit the men commenced with
pick and spade to hack out an opening like a very narrow doorway.

As the earth was broken down and shoveled back, the doorway gradually
grew to be a passage. In this two men at a time worked in turn, the one
on the right-hand side making a narrow cut that barely gave him
shoulder-play, the second man on the left working a few paces in the
rear and widening the passage.

Necessarily it was slow work, because only these two men could reach
the face of the cut, and because it had to be of sufficient depth to
allow a man to work upright without his head showing above the ground.
But because they worked in short reliefs and put every ounce of energy
into their task, they made surprising and unusual progress.

Lieutenant Riley, who was in command of the listening-post for that
night, left the workers to themselves, both because it was necessary
for him to keep a sharp look-out in order to give warning of any
attempt to rush the working party, and because officially he was not
supposed to know anything of any sap to an officially unrecognized dead
German General.

When he w
