The sound of rifle-shots was quickly succeeded by the distant boom of guns. Then the sound was swallowed up in the roar of the big guns of the forts, and it seemed as though a tremendous attack was in progress. The streets of the town instantly began to fill with excited people, until it appeared as though everyone had left his work to discuss the situation and listen to the noise of battle. Through the crowds pressed small bodies of soldiers dispatched as reinforcements to the ring of forts surrounding the town.
Max and Dale followed one of these parties at a respectful distance, and climbed with them from the cup-like hollow in which Liége is situated to the hills beyond. The soldiers were bound for one of the forts on the eastward side, and, as they reached the higher ground, the two lads caught their first glimpse of the fighting. Darkness was coming on, and away in the distance they could see the intensely bright flashes of high-explosive shells bursting on or around the forts, as well as the flame of the fortress guns belching forth their replies. As it grew darker the duel grew more intense, and lasted without intermission throughout the night till three or four o'clock in the morning.
By that time the forts were apparently thought to have been sufficiently damaged to permit of an assault, and the German infantry were flung against them in massed formation. Unfortunately for them, however, the guns had not been heavy enough to make any impression on the steel cupolas which sheltered the big guns of the forts, and, as the infantry pressed forward to the attack, they were literally swept away by a devastating shell-fire from the forts attacked and those flanking them.
Again and again fresh masses were sent forward to the assault, only to meet with a similar fate. In the attack on one of the forts the infantry, favoured no doubt by the formation of the ground, were able to get so close that the guns could not be depressed sufficiently to reach them. They believed the fort as good as won, and with cheers of exultation pressed on to the final assault. But at the corners of the forts quick-firing guns were stationed, and these and the infantry lining the parapets mowed them down as surely as the big guns.
In the wide spaces between the forts the Belgian field army had entrenched, and with rifle-fire and frequent bayonet attacks frustrated every attempt of the German infantry to break through.
The infantry assaults lasted until eight o'clock in the morning, when the Germans withdrew, heavily shaken. They had hoped to rush the forts with heavy masses of infantry, supported only by light artillery, and they had failed. They now waited for the heavy guns, which were already on the road, to arrive, and very soon forts Fléron and Chaudfontaine were deluged with an accurate fire of enormous shells, so powerful as to overturn the massive cupolas and to pierce concrete walls twelve feet thick as though they were made of butter. Such shells as these they had never been built to withstand, and it was not long before they succumbed, thus opening a way for the invaders towards the town itself.
Forts Evegnée and Barchon soon shared the same fate, and the Belgian field army, which had continued to maintain an heroic resistance, began to fall back on the town.
Max and Dale had not been allowed to see much of these events. Before midnight they were accosted by a patrol and ordered to return to the safety of the town.
Early the following day, before the fall of the forts and the retreat of the Belgian army, Max and Dale carried out their intention of presenting themselves at the casting-shops and lending a hand in the making of shells. To their satisfaction they found the work going forward with splendid energy and smoothness, and, with their own ardour kindled by the sights they had seen the previous night, they joined zealously in the work.
Presently it came home to Max that there had been considerable changes in the personnel of the shop since he had last worked there. The men he looked out for—those with whom he had been on most friendly terms when he was there—were gone, and their places were taken by other and, for the most part, younger men, all quite strangers to the place so far as he could see.
