"I can smell a peat fire!" one of the men exclaimed.
"This is the entrance, no doubt," Captain O'Connor said.

"See, the bottom is evidently worn by feet.

The passage must have been used for a long time; but it's an awkward place to follow desperate men into." "It is, indeed," Lieutenant Adcock agreed.

"They could shoot us down one after one as we go in.

They would see us against the light, while we should be able to make out nothing." "Surrender in there!" Captain O'Connor shouted.
