(3) Armistice Convention of November 11,1918, Clause XIV; obligation to cease at once all requisitions, seizures or coercive measures in Russian territory. The German troops have continued to have recourse to such measures;

A certain number of the above provisions which have not been executed or have not been executed in full have been renewed by the Treaty of June 28, 1919, whose coming into force will ipso facto render the sanctions there provided applicable. This applies particularly to the various measures to be taken on account of reparation.
Further, the question of the evacuation of the Baltic provinces has been the subject of an exchange of notes and of decisions which are being carried out. The Allied and Associated Powers expressly confirming the contents of their notes, Germany by the present Protocol undertakes to continue to execute them faithfully and strictly.
Finally, as the Allied and Associated Powers could not allow to p'ass without penalty the other failures to execute the Armistice Conventions and violations so serious as the destruction of the German fleet at Scapa Flow, the destruction of U.C. 48 off Ferrol and the destruction in the North Sea ofcertain submarines on their way to England for surrender, Germany undertakes:
(1) A. To hand over as reparation for the destruction of the German fleet at Scapa Flow: .

The ongoing refusal of the United States to ratify the Versailles Treaty meant that for the U.S., World War One technically remained ongoing.

Today, due to the treaty, was the beginning date for the League of Nations, which technically remained in existence until 1946.

Senate Minority Leader, Oscar Underwood.

In the U.S., the House of Representatives refused to seat Victor L. Berger, a duly elected member from Winsconson, who had been convicted under the Espionage Act.  Berger was an Austrian American member of the Socialist Party whose newspaper had been opposed to the war. The Supreme Court would overturn his conviction in 1921.

 Victor L. Berger after Congress refused to seat him in the House of Representatives, January 10, 1920.

World War One, therefore, remained very much a thing.

In Washington D. C., representatives of the Soviet Union were in town.

In Russia, a platoon of American soldiers under Sheridan Wyoming's 2d Lt. Paul Kendall defeated an attack by a Soviet armored train near Posolyskaya, Siberia (entry from WyoHistory.org).  Armored trains had become a strange but big feature of the Russian Civil War.

Kendall had been born in Kansas but raised in Sheridan.  He entered West Point in 1916 and graduated in 1918, due to the shortened class cycle World War One caused.  He received the Distinguished Service Cross for his action in Siberia on this day.

Kendall would go on to a career in the U.S. Army and rose to the rank of Lt. Gen., commanding troops in World War Two and the Korean War.
