The United States First Army as a fighting group was
initially commissioned in France in 1918 at the height of WW1 as American
infantry forces arrived in France in sufficient numbers under General John J
Pershing to constitute an Army. The term First Army was thus coined to mark the
first functional American Army that assembled in France on their way to the
Western front in support of the Allies in WW1 in 1918. The US First Army was
thus activated under General Hunter Liggett who took command of the activated
force on the 10th of August as the first of the three United States
field Armies that were established as part of the Allied Expeditionary Force .
The First Army was thus to prove a veritable training
ground for many notable officers that were to emerge later during WW2,
following the end of WW1 in November of 1918. The First Army served as part of
an occupation force in Germany until its demobilization and inactivation in
April 1919.
The First Army however continued to exist as part of
the four American Armies that were created when Douglas MacArthur was Army
Chief and had to re-organize the Army in compliance with the National Defense
Act of 1916 which was amended in 1920. The First Army was thus located in the
North east of the United States with its headquarters at Fort Jay’s Governor’s
Island in New York. On 11th September 1933, it was thus re-activated
under the command of General Dennis E Dolan.
The First Army was composed of three Corps, with the
first Area Corps being quartered in Boston, the second Corp Area was situated
at Fort Jay, Governor’s Island in New York and the third Corp was situated at
Fort Howard (Maryland) near Baltimore Maryland.
First Army as it then was, was more of an
administrative unit saddled with the responsibility of training the regular army
reserve and National Guards units in the three Corps Area. In 1938 , First
Army under the command of General Hugh A
Drum was tasked with the responsibility
of creating a true field Army as the wind of war began to blow all over Europe.
A Staff recruitment program began and its troops were programmed to take part in
large scale military exercises in Louisiana and North Carolina between 1939 and
1941.
As the United States entered the war in 1941, General
Dolan was given the command of the newly established Eastern Defense Command
which he held until he retired in 1943 as he approached retirement age. The
command of the First Army thus passed over to General Grunnert who remained in
control until the First Army Headquarters was moved to Bristol in England in
January 1944 under the command of Lieutenant General Omar N Bradley.
