He came to America in 1862 and became an officer in the Confederate States Army, serving with cavalryman John Hunt Morgan, General Braxton Bragg, and General J.E.B. Stuart. He resigned from the Confederate Army in 1864[4] to join a plot to take over the governments of Ohio, Indiana, and Illinois and establish a Northwestern Confederacy.

In what became known as the "Chicago Conspiracy", Grenfell was tried, convicted, and sentenced to hang.[5][6]
