Was Charles Schenck sent to prison after the Supreme Court ruling?

United States v. Schenck et al., 253 F. 212 (E. D. Pa. 1918)

Yes. The US Supreme Court affirmed the US District decision. Judge Whitaker Thompson had found both Schenck and Baer guilty under the Espionage Act and sentenced them to remarkably short terms. The maximum penalty for Schenck's alleged crime was 10 years in prison, plus a fine, for each of the three counts charged. Schenck was only sentenced to six months in prison; Baer was sentenced to 90 days.
