"but the war came to America in March..."See in text(Part V)
“The war” alludes to World War I that began in Europe in July 1914 after the assassination of Archduke Franz Ferdinand of Austria-Hungary. The war initially pitted the Central Powers (Germany, Austria-Hungary, and Turkey) against the Allies (France, Great Britain, Russia, Italy, and Japan). The United States remained neutral until August 1917 and then joined the Allies in defeating the Central Powers in 1918. American troops did not arrive in Europe in significant numbers until mid-1918.
