Maybe it means that there’s a difference between how much land they own or something. It says there was a difference between the amount of land they occupied and the amount of land they couldn’t control. So maybe they didn’t own/have a lot of land but there was a lot of land they couldn’t get to/take over etc. or maybe this situation could be vice versa so they have a ton of land but only a little isn’t “controlled” let me know if this helps sorry if it’s confusing I’m just guessing based on the context clues :)
1861 to 1865 the war known as the Civil War was in process. It was on of the bloodiest fights in history The war took place in the eleven southern states, where the union took the win. Out of the 34 U.S states 7 of the slave states declared secession from the United States and formed the Confederate States of America. In 1861 war started as the states attacked a U.S fortress called Fort Sumter.
The confederacy grew to 11 states instead of 7. After they had taken over two more states and a couple of western states as well. The war left thousands dead, and family's devastated. The war ended because the confederate armies was surrendering after the corrupt government of the confederacy.
