They went on. Curious glances were thrown at them by troops of cavalry off-saddled by the roadside. Uhlans in an armoured car! They must be on special service. With his heart in his mouth Kenneth followed the road for a full mile through the lines. The country became clearer of men as they proceeded, but as Kenneth was again increasing speed he noticed a strong force of infantry posted ahead of them at some distance to the right of the road. "They are supports," said Pariset. "We shall find a battery ahead." In less than two miles they came to a number of ammunition and transport wagons, parked in the rear of a battery of six guns. A patrol on the road signalled to them to halt. Kenneth pulled up, but before the sergeant could address him, he asked urgently: "Where is the commandant? Quick! I haven’t a minute to lose." The man pointed to a spot about half a mile in front. Kenneth, without waiting for more, opened out, and the car quickly gained speed. "It’s touch and go now," he said, almost in a whisper. "The guns are unlimbered for action," said Pariset. "If we pass they’ll know we are enemies." "Nothing else for it," replied Kenneth, setting his teeth. "We must trust to our speed. Keep a look-out, Granger." Thenceforth he concentrated all his attention upon the car. It sped on, crossed a small bridge over a rivulet, and swept up a short hill on the near side of which six guns were emplaced. "Eight inchers," murmured Granger. He had his eye fixed on the officer who had been pointed out as the commandant, and who, at this moment, was listening at the receiver of a field telephone. As the car approached he dropped the receiver and gave an order. The soldier next him ran towards the guns, shouting to the artillerymen, who appeared to be laying their weapons. "The game is up!" said Granger. "He’s had word of us. Press her, Amory." Kenneth opened the throttle to the utmost, and the car leapt forward like a living thing. It dashed past the commandant, past the group of gunners, topped the rise, and thundered down the slope beyond. A few revolver shots rattled on the armour. "We’re safe for a little, while they alter the range," said Granger, assuring himself at a glance that no one had been hit. The car was now running at a furious pace, the road having recently been repaired, no doubt for the easier passage of the guns. Kenneth knew that he was directly in the line of fire of the battery. On his left wound the Ourthe, with the railway almost parallel with it beyond; and as the car rushed between two clumps of woodland Pariset called over his shoulder that he had just caught sight of Fort de Boncelles, two or three miles to the west, and Fort d’Embourg a little nearer to the east. "Which shall we make for?" gasped Kenneth. "Boncelles," replied Granger. "It is nearer the French lines. We can cross by the iron bridge just below Tilff."
