The enemy then followed a tactic which was to succeed rapidly. He attacked the different fortifications in a reverse way. Thus Loncin, Lantin, Liers, and Pontisse were bombarded by batteries placed in the citadel itself and to which the Belgians could not reply without shelling the town and doing frightful damage. A battery was also placed in a bend of ground up Rue Naniot, under the "Tomb," where some of those who fell in 1830 are buried, but it was discovered and had to be withdrawn. Forts Boncelles and Embourg were attacked by guns placed on the hill at Tilff, a pretty village, which would have been completely destroyed had the firing been responded to. Finally, along the line of the plateau of Herve, no longer dominated by Barchon and Fleron, now destroyed, the enemy was able to bring into the very centre of the town four of those howitzers of 42 cms. which were later to bombard Namur, Maubeuge, and Antwerp. The following are the dates on which the different forts succumbed: Barchon and Evegnee fell on August 9th. Right from the 5th they had not ceased to be the object of continual attacks. They had valiantly resisted repeated assaults and field artillery. The heavy pieces poured in a hurricane of fire. Pontisse, which had so usefully barred the passage of the enemy below Vise, did not give way till the 12th. On the 13th Embourg surrendered after a twenty-six hours' bombardment. [Sidenote: Forts yield one by one.] The same day saw the fall of Chaudfontaine and Nameche, where two accidents happened worthy of being related. A shell burst on a cupola gun as it was finishing its movement after being loaded. The whole gun was shattered and ten men were wounded. A little while after, a shell entered the fort through the embrasure and set fire to the powder magazine. One hundred and ten artillerymen were terribly burned, fifty dying upon the spot. The 14th saw the fall of Boncelles, Liers, and Fleron. Boncelles from the 5th had offered an admirable resistance. Commandant Lefert had been wounded on the 8th, when 200 Germans, presenting themselves to surrender, treacherously fired upon him. Suffering greatly, he none the less went on directing the defence until his officers met together in a kind of council of war, and had him taken away in an ambulance. The unfortunate man was seized by a fever and became delirious. Boncelles was bombarded unceasingly for a whole day and the following morning. It was nearly destroyed, and may be considered as the fort which was the centre of the worst carnage of German soldiers. The enormous heaps of dead buried around it bear witness to the fact. Liers was put out of action by guns installed at Sainte Walburge. [Sidenote: Loncin and Lantin fall.]
