I was challenged in a foreign language. I felt it was not the British language or I would have recognised it. To make quite sure I crept up and found myself looking into the face of a German. I recognised him by his helmet. He was fumbling with his weapon so I cut off his head with my kukri. Another appeared from a slit trench and I cut him down also. I was able to do the same to two others, but one made a great deal of noise, which raised the alarm.
