There the infantry were set to work upon a line of masked entrenchments and hidden rifle pits between St Hubert and Virton that were designed to check and delay any advance from the east upon the fortified line of the Meuse. They had their orders, and for two days they worked without either a sight of the enemy or any suspicion of the disaster that had abruptly decapitated the armies of Europe, and turned the west of Paris and the centre of Berlin into blazing miniatures of the destruction of Pompeii.

And the news, when it did come, came attenuated. ‘We heard there had been mischief with aeroplanes and bombs in Paris,’ Barnet relates; ‘but it didn’t seem to follow that “They” weren’t still somewhere elaborating their plans and issuing orders. When the enemy began to emerge from the woods in front of us, we cheered and blazed away, and didn’t trouble much more about anything but the battle in hand. If now and then one cocked up an eye into the sky to see what was happening there, the rip of a bullet soon brought one down to the horizontal again....

That battle went on for three days all over a great stretch of country between Louvain on the north and Longwy to the south. It was essentially a rifle and infantry struggle. The aeroplanes do not seem to have taken any decisive share in the actual fighting for some days, though no doubt they effected the strategy from the first by preventing surprise movements. They were aeroplanes with atomic engines, but they were not provided with atomic bombs, which were manifestly unsuitable for field use, nor indeed had they any very effective kind of bomb. And though they manœuvred against each other, and there was rifle shooting at them and between them, there was little actual aerial fighting. Either the airmen were indisposed to fight or the commanders on both sides preferred to reserve these machines for scouting....

After a day or so of digging and scheming, Barnet found himself in the forefront of a battle. He had made his section of rifle pits chiefly along a line of deep dry ditch that gave a means of inter-communication, he had had the earth scattered over the adjacent field, and he had masked his preparations with tussocks of corn and poppy. The hostile advance came blindly and unsuspiciously across the fields below and would have been very cruelly handled indeed, if some one away to the right had not opened fire too soon.

‘It was a queer thrill when these fellows came into sight,’ he confesses; ‘and not a bit like manœuvres. They halted for a time on the edge of the wood and then came forward in an open line. They kept walking nearer to us and not looking at us, but away to the right of us. Even when they began to be hit, and their officers’ whistles woke them up, they didn’t seem to see us. One or two halted to fire, and then they all went back towards the wood again. They went slowly at first, looking round at us, then the shelter of the wood seemed to draw them, and they trotted. I fired rather mechanically and missed, then I fired again, and then I became earnest to hit something, made sure of my sighting, and aimed very carefully at a blue back that was dodging about in the corn. At first I couldn’t satisfy myself and didn’t shoot, his movements were so spasmodic and uncertain; then I think he came to a ditch or some such obstacle and halted for a moment. “Got you,” I whispered, and pulled the trigger.

‘I had the strangest sensations about that man. In the first instance, when I felt that I had hit him I was irradiated with joy and pride....

‘I sent him spinning. He jumped and threw up his arms....

‘Then I saw the corn tops waving and had glimpses of him flapping about. Suddenly I felt sick. I hadn’t killed him....

‘In some way he was disabled and smashed up and yet able to struggle about. I began to think....

‘For nearly two hours that Prussian was agonising in the corn. Either he was calling out or some one was shouting to him....
