[Cannoneer No. 4]

By June of 1865 there was precious little Confederate-controlled rebel territory left for the Union Army to control every square inch of. Whatever real estate Stand Watie held at that time. There was still a fair amount of Comanche, Apache, and Sioux-controlled rebel territory.

Depending upon you definition of "control," you might be surpised at the number of square miles that aren't under any effective government control now.

The generally accepted end date of the Civil War was June 19, 1865 when General Gordon Granger landed his troops in Galvaston and the Texas Confederate government ceased to exist. Stand Waitie could have run around longer up in Indian territory for all I know, but he didn't control anything and was pretty much meaningless. Yes, it took some days or weeks for the news to reach outlying districts, but June 19, the day Texas fell, is the date that Texas blacks, to this day, celebrate emancipation from slavery. That emancipation was under the terms of Lincoln's Jan. 1, 1863 executive order.
