While allied forces on both flanks retreated, the 3rd Division stood fast in the face of fantastic enemy offensives, which led to their moniker, "The Rock of the Marne."

Dickman commanded IV Corps from August to September of 1918, to include the Saint-Mihiel Offensive in September 1918.
[edit] Commanding General, I Corps
Dickman commanded I Corps from October to November 1918, to include the Meuse-Argonne Offensive.
[edit] Commanding General, Third Army, Nov. 1918-Apr. 1919
Third Army was established under the command of Dickman by General John J. Pershing in France to advance to the Rhein and hold the Coblenz bridgehead, then prepare to serve after the war as the Army of Occupation. The Third Army would have become the Army of Occupation whether or not the enemy signed the peace agreement. American fighting units not sent home were consolidated under Third Army and prepared to attack if Germany did not accept the terms of peace. The United States itself was not to sign the agreement but remained technically at war with Germany for two more years.
