General Leman ordered the retreat of the Belgian army from its advanced position, realizing that it was absolutely impossible to defend a line 33 miles long with an exhausted army, now reduced by losses to 18,000 men. He summoned his officers to a military council to lay down the new dispositions on the farther side of the Meuse, under cover of the western forts.
Suddenly, during the council, the general was startled by loud shouting and the sounds of a struggle outside. Knowing that the Germans were hammering at the gates of the city and that Fléron had fallen, he feared an advance cavalry patrol. He ran down-stairs and out of the door, to find himself confronted by eight men in German uniform.
The general darted back.
"A pistol!" he cried.
The Germans surged forward to seize the general, a crowd of Belgian civilians behind. They did not dare to touch the invaders, knowing that any effort would be deemed a "hostile act by non-combatants" which would afford excuse to the Germans for making reprisals.
With a quick movement, General Leman slipped sidewise past his would-be captors, the crowd opening to let him through. The Germans plunged into the crowd after him, but a brother officer of the general caught up his chief bodily and slung him over a neighboring wall, which chanced to be the boundary of a foundry yard. At the same instant, the rest of the officers who had been at the council came clattering out. Swords flashed out. Three of the Germans were killed and, some members of the Garde Civique being attracted by the commotion, the rest were made prisoners. They were found to be spies, who had secreted German uniforms and arms in a house next door to military headquarters, with this very intention of capturing the Belgian commanders in a moment of surprise.
With the withdrawal of the troops from the advance trenches, the holding of the eastern forts became an impossibility. Thus, on receiving news of the retreat, Major Mameche, the Commandant of Fort Chaudfontaine, the strategic value of which lay in its controlling the entrance to the Chaudfontaine railway tunnel, blocked the tunnel by colliding several engines at its mouth and then fired his powder-magazine, blowing up the fort.
Towards midday a message was received from General von Emmich, demanding the surrender of the city. The civil authorities were willing, in order to save the city from destruction, but General Leman, as Military Commandant, curtly refused to abandon the forts. He was fighting for time. Already two days had passed and only one of the six larger forts had fallen. To France and to England—which had entered the war because of Germany's violation of Belgium—every day gained then was worth a week later.
A panic followed upon General Leman's refusal, citizens who feared the results of the bombardment of the city jamming every out-bound train. Every possible influence was brought to bear on the Military Commandant. His only answer was,
"The forts must hold."
