They were three private soldiers and a stretcher-bearer, and their spokesman started off by saying that he thought it only right to come over and wish us a happy Christmas, and trusted us implicitly to keep the truce. He came from Suffolk, where he had left his best girl and a 3½ hp motor-bike! He told me that he could not get a letter to the girl, and wanted to send one through me. I made him write out a postcard in front of me, in English, and I sent it off that night. I told him that she probably would not be a bit keen to see him again. We then entered on a long discussion on every sort of thing. I was dressed in an old stocking-cap and a man's overcoat, and they took me for a corporal, a thing which I did not discourage, as I had an eye to going as near their lines as possible. [...]
I asked them what orders they had from their officers as to coming over to us, and they said none; they had just come over out of goodwill. They protested that they had no feeling of enmity towards us at all, but that everything lay with their authorities, and that being soldiers they had to obey. I believe that they were speaking the truth when they said this, and that they never wished to fire a shot again.
