A Brief Look at Ohioans in the Civil War
The state of Ohio played a key role for the United States of America during the Civil War. In fact, there were more than 310,000 Ohioans who served in the war — the third largest number of any state in the Union. Despite Ohio’s role in the war, there were Ohioans who served in the Confederate Army. Regardless of who they fought for, there were many Ohioans who rose to the rank of General during the war, which lasted from 1861 to 1865.
The Rise of Sherman and Grant
Over the course of the war, many Ohio natives rose to prominence. The most notable being Ulysses S. Grant, who went on to be elected as the 18th President of the United States, and William T. Sherman, who waged a scorched-earth campaign across the South known as “Sherman’s March to the Sea.”

Lee and Johnston Surrender
Grant and Sherman also received the formal surrenders of the Confederate commanders. On April 9, 1765, General Robert E. Lee surrendered to Grant at Appomattox Court House in Virginia. A little more than a week later, General Joseph E. Johnston surrendered to Sherman at Bennett Place, near Durham, North Carolina.
