Frank saluted and hastened back. Orders were issued, and soon every man was at his post, strung up to the highest pitch of excitement and expectancy. They strained their eyes through the baffling fog but for a while could see or hear nothing.

CHAPTER XXV

A GALLANT EXPLOIT

Were they to wait there, until that grey wave overwhelmed them, pouring into the trenches like a surging flood?

The strain of waiting was becoming almost unbearable.
