How many trials did the Schenck v. United States case have before the Supreme Court heard it?

Schenck v. United States, 249 U.S. 47 (1919), was a landmark decision of the US Supreme Court concerning enforcement of the Espionage Act of 1917 during World War I. A unanimous Supreme Court, in an opinion by Justice Oliver Wendell Holmes Jr., concluded that defendants who distributed flyers to draft-age men urging resistance to induction could be convicted of an attempt to obstruct the draft, a criminal offense. The First Amendment did not alter the well-established law in cases where the attempt was made through expressions that would be protected in other circumstances. In this opinion, Holmes said that expressions which in the circumstances were intended to result in a crime, and posed a "clear and present danger" of succeeding, could be punished.
