Charles Ewing (March 6, 1835 – June 20, 1883) was an attorney and Union Army general during the American Civil War.

He studied law, was admitted to practice and was so engaged at St. Louis, Missouri, when the civil war broke out.

He then joined the U.S. Army and was commissioned in May 1861 as a captain in the 13th Infantry, of which William T. Sherman, his brother-in-law, was colonel.

At the Battle of Vicksburg he planted the flag of his battalion on the parapet of the Confederate fort, and received a severe wound.

Based on its prior missionary initiatives the Catholic Church felt justified in operating schools at 34 of the 72 agencies, but the administration of President Ulysses S. Grant allowed them at only seven.
