The reason you're asking, I think, is because it's a bit of both- the first part is a narrative of the key events, then there is a summary of his background. However, I think the main drive is his role in the war rather than his schoolling, so I'd say it is more of a narrative than a summary- the last part is there to flesh out the character of the man in the events in the first part.
PS- I think you've missed 'it' out here after with: and was one of the five people who voted for the repeal of the Act, and with the right to not tax America anymore.
Also- the tenses here go a bit weird to my ear, but I am a British English speaker:
This will be one of the many reasons he will most likely not be punished for losing America.
Then you start using the present, which doesn't really work for me.
