"Spies work all kinds of tricks. There was the old fellow who came back to his farm just behind the lines and started to do his fall ploughing with three horses, a red, a white and a black. He did his signalling by changing the position of the white horse in the team. He was easy to catch, as a team, especially a plough team, always works in the same order. Some of our men who were farmers noticed how he was constantly changing his horses about. They talked about it among themselves a bit and at last one of them spoke of it to an officer. The alleged farmer was investigated and shot.
"Spies are almost sure to get a certain length of time to do their work before they are caught. We ran across a blacksmith who was one of the most congenial fellows you ever met. He had his shop right beside one of the main roads used by the troops in going back and forth to the trenches and he always had a stock of wine and something to eat. His shop did not keep him very busy and he was nearly always at his door. He would talk to the soldiers, give them a drink, ask where they were going and want to know how long they would be gone, so that he would be waiting to give them another glass of wine when they came back. He was very popular with the soldiers, because he was such a good fellow, always ready with a joke and a glass of wine.
"But our concentrations were known to the Boches. Our men were being shot down. We never could prepare anything in advance and bring it off successfully, because the Boches knew just where we were getting ready to do something. Some of our spy catchers got to work to find the leak. They hunted through the sector for the best place to pick up news about troop movements and they found, of course, that all the soldiers were friendly with the blacksmith. His shop was raided one day. He had been left behind by the Germans. He had a three months' store of wine and food in his cellar. Of course, he could give our men wine. But he had, also, direct telephonic communication from his cellar with the German lines. He was shot.
"The worst case that I ever knew of—but it was not the only one of the kind—was an officer in the French army who was a German spy. You can see from that how thorough the Boches are. That man had been sent from Germany to France when he was a boy. He had been educated in France and had gone to the French military schools. He was an artillery officer and one of the best. He was a lieutenant at the beginning of the war, but when the Somme offensive began he was a captain in command of a battery. For all that time he had done his work without being suspected.
"On the Somme he was in charge of his battery, which was firing ahead of our men during an advance. The battery got a signal that their range was too short and they were firing into our own men. The sergeant told the captain, but he said they were firing according to orders and not to change the range. The battery fired another round and got another signal from the infantry that they were firing short. The sergeant spoke to the captain again and the captain lost his temper and swore at the sergeant. He ordered another round at the same range and the sergeant refused. The captain tried to fire one of the guns himself.
"It was very important for the Germans to stop our advance at that point. It might have saved Combles. But the sergeant knew as much about the situation as the captain. He knew what it meant to have our troops stopped there. We might have lost a brigade. We might have lost a division. He threatened the captain with a rifle and arrested him. It is something to arrest your own captain, but the sergeant did it, and there was a drumhead court-martial and the captain was shot. He confessed, when he saw it was all up with him, and bragged of the two years he had escaped being caught and of what he had done. He was brave enough, but—Well, think of it! Educated in France, an officer in the French Army, living at the expense of France, living a lie for ten years, waiting for 'the day' to betray those who trusted him. It takes a German to do that."
