Charles Ewing, youngest of three brothers who became Union generals and brother-in-law of General William T. Sherman, was born on March 6, 1835, in Lancaster, Ohio. He was the son of Thomas Ewing, Senator from Ohio, Secretary of the Treasury, and Secretary of the Interior. Young Ewing's education was obtained at local schools, at a Dominican college, and at the University of Virginia. He studied law and was practicing in St. Louis at the outbreak of war. On May 14, 1861, he received a commission as captain of the newly authorized 13th U. S. Infantry. This regiment was stationed at Alton, Illinois, until ordered to Memphis in October, 1862, during the furore occasioned by Braxton Bragg's invasion of Kentucky. At the siege of Vicksburg, Ewing's regiment—or a battalion thereof—was a part of Francis P. Blair's division of Sherman's XV Corps, and Ewing won praise from Blair for his conduct during an assault on the Confederate works. Shortly afterward he was appointed assistant inspector general with rank of lieutenant colonel and assigned to Sherman's staff. Although there may have been nepotism in this, Ewing discharged his duties gallantly and was brevetted three times for services performed during the balance of the war, as he accompanied Sherman in many campaigns. After distinguished service at Chattanooga, in the Atlanta campaign, on the famous "March to the Sea," and in the campaign of the Caro-linas which resulted in the surrender of the Confederacy's second most important army under Joseph E. Johnston, Ewing was brevetted colonel in the regular service to rank from March 13, 1865, five days after being commissioned a full rank brigadier general of volunteers. Although Sherman's influence had something to do with all this, Ewing's own record was unassailable. After brief service as a captain of the 22nd Infantry, to which he had transferred, he resigned in 1867, and began the practice of law in Washington. He died there on June 20, 1883, and was buried in Arlington National Cemetery.
