Madrid, Spain, and Nauen, Germany, are in constant wireless communication. There are other radio stations, privately owned in Spain, which can flash messages to Germany, according to Allied intelligence officers who have investigated. And of course there are innumerable German agents, spies and propaganda disseminators infesting the land of the Dons. Secret Service reports disclose the fact that Mata-Hari was seen much in company at San Sebastian race track with a man long looked upon with suspicion by the French Government. He was a frequent caller upon her at the hotel where she stopped, and it was reported that he made good many of the big bets she placed on horses that did not materialize as winners. Soon Mata-Hari came back to Paris and the apartment near the Bois de Bologne. And once more the limousine owned by the individual whom rumor has branded a Deputy, began rolling up to her door twice a week and sometimes oftener. Then came the simultaneous Franco-British offensive at the Somme. Tanks went into action for the first time, and according to Gen. Haig's official communique his "land ships achieved satisfactory results." The tanks did achieve satisfactory results. More than that, they revolutionized offensive tactics on favorable terrain by advancing immune against rifle and machine gun bullets, or even against light trench mortars whose shells exploded at a touch. They smashed by sheer weight strong points and machine gun emplacements. They straddled trenches, enfilading the occupants and crushed in entrances to dugouts. But several of the tanks were put out of action--and not by stray shells hurtling forward from far behind the German lines. They were knocked out by small calibre _PENETRATION_ shells, fired from 37 millimetre trench cannons--the largest guns that can be handled from advanced positions. Guns specially built and rifled, and fired at high velocity and flat trajectory, so that, unlike any shell ever coughed up by a mortar, they penetrated the object struck--even though it were steel--before exploding. Instantly it became evident that the enemy had become aware of what was in store for him and had constructed an "anti-tank" gun. And when the booty in the captured German positions was examined, the British found they had several good specimens of Krupp's newest weapon. Several German officers of higher rank taken prisoners confirmed suspicions, by explaining they had received description of the tanks several weeks before, and had been instructed how to combat them. Now Mata-Hari is awaiting death and writing as she waits. She is penning her memoirs rapidly, filling scores of pages a day in a polyglot of French, German, Dutch, Javanese, Japanese and even English, according to the mood she is in, says the prison warder.
