ters
of the Avre. This enabled the German army to reach westward of the river
and spread out after crossing to flank the defenses to the north.
Gradually the left bank of the river was cleared as far north as
Moreuil. Here the high ground on the left bank between Moreuil and the
mouth of the Luce enabled the French to beat off all German attacks for
several days. Finally, however, both Moreuil and Morisel were taken and
later the village of Cassel, the Avre being thus cleared of the Allied
troops as far north as the mouth of the Luce. From Cassel to the Somme,
however, the German forces found themselves in serious difficulties.
About Hangard, particularly, the fighting was exceptionally heavy; but
after changing hands several times, the Germans were finally thrown
across to the southern bank of the Luce and there held in place. From
Hangard north to the Somme the result was the same. After struggling for
days against the troops on the high plateau of which Villers-Bretonneux
is the centre, the Germans were brought to a standstill in their
attempts to approach Amiens by way of the Avre-Somme angle.
[Sidenote: The British retire behind the Ancre.]
[Sidenote: Albert is taken; but Germans are soon held.]
In the battlefield north of the Somme, the British retired slowly until
they were safely behind the Ancre River, which figured so prominently in
the battle of the Somme in 1916. Taking Albert, an important British
base, the Germans tried desperately to push beyond and reach the
railroad which runs along the lower Ancre from Amiens to Albert. Failing
in this, they struck heavily in the angle between the Somme and the
Ancre in order to flank the line north of Albert from the high ground
north-east of Corbie. Here also they met with defeat, so that from
Beaumont-Hamel southward the Allied line became stationary.
[Sidenote: The situation of the Germans.]
[Sidenote: To win peace the Germans must destroy an army.]
At this point in the battle the Germans found themselves in this
situation: from Montdidier westward the French lines were firmly
established first along a series of small but well defined heights as
far as Noyons and thence along the southern bank of the Oise as far as
the lower forest of Coucy. This side of the wedge was firmly fixed and
capable of great resistance. Moreover, to expend time and men in an
attack on this front would mean a serious departure from the German
plan, as success here would mean an
