The two chums were only partly correct in their surmise. Konrad von Feldoffer, on realizing that he had been recognized by a couple of men who, he thought, belonged to another battalion, had rather prematurely bolted for the German lines. In the guise of a New Zealander he had been hoping to gather useful and definite information concerning the forthcoming advance. Since most of the Diggers were in ignorance of the mining operations under Messines Ridge, von Feldoffer gained very little information on that point.
