out affair, all the Great Powers looked for other allies
around the globe to tip the balance. They also
sought new war fronts on which to achieve victory.

fight as units under
American command
rather than being split
up by battalions to
augment British and
French regiments and
brigades.

 Pershing is often given credit
for Allied victories. However,
junior officers of the time like
Douglas MacArthur (later
commander of the U.S. Army
in the Pacific during World War
II) saw him as a “desk general”
commanding far back from the
lines.
 He controversially ordered his
troops to continue fighting after
the armistice was signed. This
resulted in 3,500 U.S.
casualties on the last day of
the war, an act which was
regarded as murder by several
officers under his command.
