President Andrew Jackson didn't want to have a war with Mexico but also did not want to deal with adding what could be another slave State. Jackson believes that if Texas was annexed, the other countries would view the United States a traitors. He was passionate about Texas but he was more passionate about keeping the Union together.
Concentration camps were more along the lines of camps that were used to hold and secure people, usually civilians, that were unwanted or suspicious to the country holding them. Many people like to attune it to just Jewish people in Nazi Germany, but concentration camps have been used by the US against Native Americans and Japanese people, they were also used by the Japanese during world war II as well as the Russians.
A Death camp is exactly what it sounds like, usually used only to eliminate evidence, humans, or unneeded Prisoners of War, traitors, or civilians. Most death camps that were recorded in history came from Nazi Germany and Japan during WWII.

The ruling is that he is still a slave to him master even tho he is in a
slave free state. And that he would still have to go back home with his
master.
Hope this helps
