The United States became involved in World War I in April of 1917 -- with war against Germany being declared on the 6th of that month. This declaration followed from general antipathy towards Germany, even outright rage, as a result of the sinking of American ships by German submarines and the threat of still more sinkings to come, among other motivations for going to war.
April 6, 1917
Deadliest battle America has been involved in to date was the Battle of Meuse-Argonne in WWI (26,277 deaths) Deadliest battle on American soil was Gettysburg in US Civil War (7,863)
