The lost the land when the taxes weren’t paid.
Certainly true, and without a crop, which was burned or seized, there was no money to pay the property tax. The property tax rate was raised by the Occupation government to a level that most land owners could not pay. The land was auctioned and bought by people who had the money to buy it. They were called carpetbaggers. In many places like the 5 western counties in Misssouri, south of the Missouri River, the Union army burned the houses, the fences, and the crops, including those of union supporters. The people were driven out. Very few of them were slave holders. They didn’t call it the Border Wars for nothing.
