Under command of Major General John Pershing, his soldiers outnumbering the Germans they fought against.

Ever since the U.S. entered WW I in 1917, it had been sending divisions to fight in Europe in support of the major French or British units. However, later that year in 1917, President Woodrow Wilson sent the American Expeditionary Force (AEF), commanded and trained by General John J. Pershing.

The timing of its arrival was crucial to define the destiny of the war. This force came at a time when France and Britain's troops were weak and tired of the war. The major effect of its arrival is that the force helped counter the German forces, aided the Allies and helped to end the war, in which the allies gained the victory.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
