As soon as the general and his aide have departed from Bundok, Goto Dengo goes and finds Wing, who is supervising the boring of the diagonal shaft towards Lake Yamamoto. He is one of those lead-by-example types and so he is way up at the rock face, working a drill, at the end of a few hundred meters of tunnel so narrow that it has to be negotiated on hands and knees. Goto Dengo has to present himself at the Golgotha end of the tunnel and send a messenger crawling up into it, wearing a rusty helmet to protect himself from the shattered stone that drizzles down from the rock face.
