I want to know the answer to the following question:
What happened to Edward Oxford to after he was found guilty of high treason?
All the background I'm provided with is that "During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother.". Is that enough to answer the question?
Answer: no
