A number of monoplanes, ‘like giant swallows,’ he notes, were scouting in the pink evening sky.

Barnet’s battalion was sent through the Sedan country to a place called Virton, and thence to a point in the woods on the line to Jemelle.  Here they detrained, bivouacked uneasily by the railway—­trains and stores were passing along it all night—­and next morning he:  marched eastward through a cold, overcast dawn, and a morning, first cloudy and then blazing, over a large spacious country-side interspersed by forest towards Arlon.

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 manoeuvred 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.
