Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France.  The tide of the advance was dramatically turned with the Battle of the Marne.  Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.

American entry into World War I in early April 1917 resulted in the American Expeditionary Force (AEF) on the Western Front, under General John J. Pershing, being engaged in 13 campaigns, during the period 1917–18, for which campaign streamers were designated.
