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 counter-attacked. When dawn broke, a general engagement was
in progress. About eight o'clock the Germans were compelled to
withdraw.
