At the 11th hour on the 11th day of the 11th month of 1918, the
Great War ended. At 5 a.m. that morning, Germany, bereft of
manpower and supplies and faced with imminent invasion,
signed an armistice agreement with the Allies in a railroad car
outside Compiégne, France.

President John F. Kennedy decided to increase military aid to
South Vietnam without committing U.S. combat troops. He was concerned at the advances being made by the communist Viet 
Cong, but did not want to become involved in a land war in
Vietnam.

Kennedy hoped the military aid would be sufficient to strengthen
the Saigon government and its armed forces against the Viet
Cong. Ultimately it was not, and Kennedy ended up sending
additional support in the form of U.S. military advisors and
American helicopter units
