In July and August, the tide turned with a series of French, then British,
counterattacks. In September, the huge American forces recently arrived
went into action. By now, the Allies, especially the British, were as sophisticated
as the Germans in using their heavy guns. They approached the
Germans' skill in effective infantry attacks. The most visible example of the
new tools available to the Allies for successful attacks was the tank.
Nonetheless, neither side achieved a clear breakthrough in 1918. Even
the spectacular feats of tank warfare on one day led to painstaking infantry
advances the day following. Nothing like Erwin Rommel's thrust to the
English Channel in 1940 or George Patton's breakout from Normandy in
1944 took place.
The Allied victory was based primarily on the fruits of attrition and the
weight of numbers. An exhausted Germany had thrown its last resources
into the contest in the spring and early summer of 1918 and suffered final
and intolerable losses. German reinforcements entering the front hues found
discipline in some units crumbling. As Ludendorff recorded in his memoirs:
'T was told of deeds of glorious valour, but also of behavior which ... I
should not have thought possible in the German Army; whole bodies of our
men had surrendered to single troopers The officers in many places had
lost their influence and allowed themselves to be swept along with the
rest." 25 Even so, German armies retired in good order, and the Allied
advance was delayed, sometimes virtually stopped, by such effective defenses
as the ones the Americans faced on the Meuse-Argonne sector in the
last two months of the war. In the words of Bemadotte Schmitt and Harold
Vedeler, the Germans were "a beaten army, though not a routed army, and
knew it at the time."
