This bridge over the Meuse at Liege was blown up by the Belgians to delay the German advance. The German army crossed on pontoon bridges.
It was through this otherwise undefended gap that Von Kluck purposed to advance his German army after the presumed immediate fall of Liege, to that end having seized the Meuse crossing at Visé. The railway line to Aix-la-Chapelle was dominated by Fort Fleron, while the minor Forts Chaudfontaine and Embourg, to the south, commanded the trunk line by way of Liege into Belgium. On the plateau, above Liege, Fort Loncin held the railway junction of Ans and the lines running from Liege north and west. Finally, the forts were not constructed on a geometric circle, but in such manner that the fire of any two was calculated to hold an enemy at bay should a third between them fall. This was probably an accurate theory before German guns of an unimagined caliber and range were brought into action.
In command of the Belgian forts at Liege was General Leman. He had served under Brialmont, and was pronounced a serious and efficient officer. He was a zealous military student, physically extremely active, and constantly on the watch for any relaxation of discipline. These qualities enabled him to grasp at the outset the weakness of his position.
If the Germans believed the refusal to grant a free passage for their armies through Belgium to be little more than a diplomatic protest, it would seem the Belgian Government was equally mistaken in doubting the Germans would force a way through an international treaty of Belgian neutrality. Consequently, the German crossing of the frontier discovered Belgium with her mobilization but half complete, mainly on a line for the defense of Brussels and Antwerp. It had been estimated by Brialmont that 75,000 men of all arms were necessary for the defense of Liege on a war footing, probably 35,000 was the total force hastily gathered in the emergency to withstand the German assault on the fortifications. It included the Civic Guard.
General Leman realized, therefore, that, without a supporting field army, it would be impossible for him to hold the German hosts before Liege for more than a few days—a week at most.
But he hoped within such time the French or British would march to his relief. Thus his chief concern was for the forts protecting the railway leading from Namur down the Meuse Valley into Liege—the line of a French or British advance.
On the afternoon of August 4, 1914, German patrols appeared on the left bank of the Meuse, approaching from Visé. They were also observed by the sentries on Forts Barchon, Evegnée and Fleron. German infantry and artillery presently came into view with the unmistakable object of beginning the attack on those forts. The forts fired a few shots by way of a challenge. As evening fell the woods began to echo with the roar of artillery. Later, Forts Fleron, Chaudfontaine and Embourg were added to the German bombardment. The Germans used long range field pieces with powerful explosive shells. The fire proved to be remarkably accurate. As their shells exploded on the cupolas and platforms of the forts, the garrisons in their confined citadels began to experience that inferno of vibrations which subsequently deprived them of the incentive to eat or sleep. The Belgians replied vigorously, but owing to the broken nature of the country, and the forethought with which the Germans took advantage of every form of gun cover, apparently little execution was dealt upon the enemy. However, the Belgians claimed to have silenced two of the German pieces.
In the darkness of this historic night of August 4, 1914, the flames of the fortress guns pierced the immediate night with vivid streaks. Their searchlights swept in broad streams the wooded slopes opposite. The cannonade resounded over Liege, as if with constant peals of thunder. In the city civilians sought the shelter of their cellars, but few of the German shells escaped their range upon the forts to disturb them.
This exchange of artillery went on until near daybreak of August 5, 1914, when infantry fire from the woods to the right of Fort Embourg apprised the defenders that the Germans were advancing to the attack. The Germans came on in their customary massed formation. The prevalent opinion that in German tactics such action was employed to hearten the individual soldier, was denied by their General Staff. In their opinion an advantage was thus gained by the concentration of rifle fire. Belgian infantry withstood the assault, and counterattacked. When dawn broke, a general engagement was in progress. About eight o'clock the Germans were compelled to withdraw.
Beginning of German Invasion of Belgium.
The first engagement of the war was won by the Belgians. It was reported that the Belgian fire had swept the Germans down in thousands, but this was denied by German authorities. Up to this time the German forces before Liege were chiefly Von Kluck's vanguard under Von Emmich, his second line of advance, and detachments of Von Bülow's army. On the Belgian side no attempt was made to follow up the advantage. The reason given is that the Germans were seen to be in strong cavalry force, an arm lost totally in the military complement of Liege. The German losses were undoubtedly severe, especially in front of Fort Barchon. This was one of the major forts, triangular in shape, and surrounded by a ditch and barbed wire entanglements. The armament of these major forts had recently been reenforced by night, secretly, with guns of heavier caliber from Antwerp. As they outmatched the German field pieces of the first attack, presumably the German Intelligence Department had failed in news of them. An armistice requested by the Germans to gather in the wounded and bury the dead was refused. Thereupon the artillery duel recommenced.
A hot and oppressive day disclosed woods rent and scarred, standing wheat fields shell-plowed and trampled, and farm houses set ablaze. The bringing of the Belgian wounded into Liege apprised the citizens that their side had also suffered considerably. Meanwhile, the Germans were reenforced by the Tenth Hanoverian Army Corps, from command of which General von Emmich had been detached to lead Von Kluck's vanguard, also artillery with 8.4-inch howitzers.
The bombardment on this 5th day of August, 1914, now stretched from Visé around the Meuse right bank half circle of forts to embrace Pontisse and Boncelles at its extremities. In a few hours infantry attack began again. The Germans advanced in masses by short rushes, dropping to fire rifle volleys, and then onward with unflinching determination. The forts, wreathed in smoke, blazed shells among them; their machine guns spraying streams of bullets. The Germans were repulsed and compelled to retire, but only to re-form for a fresh assault. Both Belgian and German aeroplanes flew overhead to signal their respective gunners. A Zeppelin was observed, but did not come within range of Belgian fire. The Belgians claim to have shot down one German aeroplane, and another is said to have been brought to earth by flying within range of its own artillery.
During the morning of August 5, Fort Fleron was put out of action by shell destruction of its cupola-hoisting machinery. This proved a weak point in Brialmont's fortress plan. It was presently discovered that the fire of the supporting forts Evegnée and Chaudfontaine could not command the lines forming the apex of their triangle. Further, since the Belgian infantry was not in sufficient force to hold the lines between the forts, a railway into Liege fell to the enemy. The fighting here was of such a desperate nature, that General Leman hastened to reenforce with all his reserve.
This battle went on during the afternoon and night of August 5, into the morning of August 6, 1914. But the fall of Fort Fleron began to tell in favor of the Germans. Belgian resistance perforce weakened. The ceaseless pounding of the German 8.4-inch howitzers smashed the inner concrete and stone protective armor of the forts, as if of little more avail than cardboard. At intervals on August 6, Forts Chaudfontaine, Evegnée and Barchon fell under the terrific hail of German shells. A way was now opened into the city, though, for the most part, still contested by Belgian infantry. A party of German hussars availed themselves of some unguarded path to make a daring but ineffectual dash to capture General Leman and his staff.
General Leman was consulting with his officers at military headquarters, on August 6, 1914, when they were startled by shouts outside. He rushed forth into a crowd of citizens to encounter eight men in German uniform. General Leman cried for a revolver to defend himself, but another officer, fearing the Germans had entered the city in force, lifted him up over a foundry wall. Both Leman and the officer made their escape by way of an adjacent house. Belgian Civic Guards hastening to the scene dispatched an officer and two men
