What does it mean:

I am definintly the best at history, so if someone else answers maybe take their answer but here's what I think(51% of myself thinks that I don't have the right answer but eh): The people won a battle, and the constitoution  proves/confirms that this happened because people had confidence in themselves in their courage, skills, and discipline. These people are seafearing men, achieving protecters of their insulted flag and injured rights. Something like that. Hopefully it is correct.
