At 4.30, we knew by the red fuses, that the enemy was retreating. The interval had not been crossed and not a single wire of the accessory defences had been cut. This success gave our men fresh hope and confidence; they were almost joyful. Their fatigue was very evident though. As soon as the enemy attack was withdrawn, the firing gallery stopped replying to calls. We went to see what was happening and found the whole staff asleep. The officer had thrown himself down on a mattress, and on getting up he staggered with fatigue. There had been a few minutes' respite and all the men, not having to keep on the alert, had succumbed to their exhaustion.
The Commander of the Fort himself, a little time before, had fallen asleep in a cupola in full action.
The Commander of the Fort Artillery, who still could not walk, was evacuated, together with another wounded man. Food was then distributed and repairs done. The replenishing of the cupolas with ammunition was effected, thanks to the covered passages that were still intact.
At 7.20 the bombardment began once more. Enemy aëroplanes had been to see the state of the Fort, and the destruction then became systematic. Every six minutes a 420 projectile arrived—"the block train," as the men called it. We watched the progress of the bombardment with great anxiety.
The projectiles could be heard from afar, and they struck first the left and then the right of the Fort. The flank salients being very close together, the blow struck either one or the other of these projections indifferently. The soldiers remarked this and made bets as soon as the sound of the projectiles was heard in the distance. The salient I. was well sprinkled first and then the firing was on the front. The covered passage to the right of the front gave way. It was by this that the ammunition supply for the cupolas was effected. How many men were under the ruins? A roll-call was impossible. We had to evacuate part of the front, and half of the staff had to take refuge in the semi-caponier on the right. All telephonic and telegraphic communication was cut off. The Lierre office no longer replied, as the town had been evacuated.
The firing now approached the right semi-caponier, and a shell burst fifteen yards from the entrance.
The men were ordered to keep at the other side of the Fort, which was no longer bombarded. It was impossible to warn those who had remained at the front caponier. The explosions continued every six minutes, and the bombardment was carried on systematically by series, and in an invariable manner. By observing where the projectiles fell, we could calculate just the moment when it would be time to move away. The first firing of a series was dangerous for us. As soon as the explosions followed each other too quickly, the men collected together, as soon as they heard the whizzing, waited for the projectile to fall, and then rushed off to their fresh shelter.
This game could not, however, continue very long. The projectiles seemed to be following us, and the arches gave way one after another after we had left them.
Towards 2 o'clock in the afternoon, the order was given to the Commander of the Fusiliers to collect his men in groups and to send them, in the intervals between the firing, to the postern gate of the Fort, which, so far, was intact. The order was carried out and we were able to pass, in the most miraculous way, between the projectiles. The firing now continued for some time on the left part of the Fort and the men grouped themselves on the berm in the space which separates the parapet from the moat against the outside talus of the semi-front of the right gorge. Just at that moment the two hundred and thirty-fifth 420 shell fell on the Fort.
With the exception of the danger from the pieces of masonry and from the explosions, which did not injure any one seriously, we were fairly safe. Towards noon, the projectiles came more frequently and the men who were under the entrance postern and in the guard-room were called inside. All the defence works were by this time either destroyed or of no use. The corridors and posterns were obstructed by huge blocks of masonry. The cupola of 5 centimetres 7 of salient IV. was the only one which appeared to be in good condition, but it was impossible to get to it. The garrison's last shelter was now threatened in its turn. A projectile burst on the edge of the moat, a few yards beyond the entrance to the Fort, and this caused a moment's panic. The bombardment continued, making it impossible for us to reoccupy the building. At 2.30, a formidable detonation and a dense smoke made us presume that the Koningshoyckt Fort had just been blown up.
