In view of the time lost by the 9th corps in forcing a way across the Meuse General von Emmich was obliged to hold off the intended attack by the 7th corps. These troops unsupported were too weak to risk such an operation. The advance, besides, of the 10th corps by way of Verviers had not been so rapid as had been intended. Their march through a stretch of country, hilly and for the most part well wooded, had been actively harassed by a mobile force of Belgians intimately acquainted with the defensive possibilities of the region. In the meantime, the preparations for resistance were pushed forward night and day, and General von Emmich knew that his task became tougher with every hour that was lost. He was well aware of the weak spots of the fortress. Of its surrounding ring of twelve forts, six only were large and powerfully armed; the remainder were smaller works. The latter, however, were not regularly alternated with the larger forts. Two of the smaller works, Chaudfontaine and Embourg, were placed close together on the south-west; two others, Lantin and Liers, filled a gap of more than 10 miles across on the north-east; a fifth, Evegnée, was midway between the larger forts of Barchon and Fleron on the south-east. These were the three points selected for the assault. Fort Evegnée covered by the fire of both Barchon and Fleron was the most difficult point of the three. Needless to say, General Leman, equally well aware of the strong and weak points, had taken his measures accordingly. Evidently feeling that he could not afford delay, the German commander on August 5 launched the 7th army corps against Fort Evegnée with the object of taking it by storm. The bombardment had begun the day before, following a demand for surrender which had been refused, but the German howitzers were outranged by the heavy ordnance of the larger forts. The fire of the latter, skilfully directed, had proved unexpectedly destructive. Taking advantage of such cover as had been left by partly demolished buildings, walls, and felled trees, the German infantry at the distance for the final rush closed up into columns of attack and, with the support of their artillery, endeavoured to carry the trenches on both sides of Evegnée with the bayonet. Not only, however, were they enfiladed by the guns of Barchon and Fleron, but they suffered huge losses from land mines. The tactics adopted by the Belgians were well advised. The troops in the trenches held their fire until the attack fell into difficulties with the entanglements, and then withered the assault by well-aimed volleys. The onset, nevertheless, was too determined to be shaken. Despite their heavy losses, the Germans negotiated the ditches, and though they were mowed down in hundreds by the machine guns now turned upon them, some gained the crest of the trenches. The earthworks were filled with dying and dead, but the storming parties still advanced over the bodies of their fallen comrades.
