One battalion came back from the front with an additional member. He was a large dog of uncertain breed who had deserted from the German lines. At least it was hard to say whether he belonged to the German army or the French. The French first saw him one afternoon when he came lumbering across No Man's Land and pushed himself through the wire in a place where it had grown a bit slack. One French soldier fired at him. The poilu thought it might be a new trick of the Germans. For all he knew a couple of Boches might have been concealed inside the big hound. He was no marksman, this soldier, for he missed the dog who promptly turned sharply to the left and came in at another point in the trenches. The soldiers made him welcome although there was some discussion as to what his nationality might be. It was evident that he had come across from the German lines, but it was possible that he was a French dog captured in one of the villages which fell to the invaders. The men in the front line tried him with all the German they knew--"You German pig," "what's your regiment?" "damn the Kaiser," "to Berlin," and a few others. He indicated no understanding of the phrases. Later he was taken further back and examined at length by an intelligence officer but no single German word could be found which he seemed to recognize. On the other hand it was ascertained that he was equally ignorant of French. However, he understood signs, would bark for a bone and never missed an invitation to eat. During the first week of his stay the soldiers were generous in giving him a share of their rations. Later he became an old friend and did not fare so well. One night he disappeared and an outpost saw him lumbering back to the German lines. The Boches were out on patrol that night and apparently the big dog reached their lines without being fired upon. He was gone three weeks and then he returned for a long stay with the French. So it went on. He never affiliated himself permanently with either army and he never gave away secrets. Possibly his coming gave some sign of declining morale across the way for when the men became cross and testy the big dog simply changed sides. There was never any indication that he had been underfed even when rumors were strongest about the food shortage in Germany. The Boches took a pride in belying these stories, as best they could, by keeping the hound sleek and fat. The French called him Quatre Cent Vingt after the big gun but nobody knew for certain his German alias. Once when he left the German lines in broad daylight the Boches all along the line were heard whistling for him to come back, but no one called him by name. The French chose to believe that across the way he was known as "Kamerad," but there was no evidence on this point. It is true that he would stand on his hind legs and wave his paws when anybody said "Kamerad," but this was a trick and took teaching.
