Answer:
Another example of 1) English Patriotism and 2) Henry trying to be "one of the guys,." He's offering them the chance to be elevated to the status of gentleman because of their bravery. Can also be compare this to the way in which the French discuss the battle of Harfleur, which is over-confident and basically talks about how they're going to take advantage of how weak the English army is. Talks about how they'll get to show their scars and remember what happens today, years from now==manhood. Henry implicits elevates the men he's fighting alongside to his own level of nobility-- so is he pushing himself down, or pulling the other soldiers up?
The subject of the poem is life. When you look at it in depth, its entirety is a metaphor for the passing of life. Nature's first green is gold (the birth of a child, or new life), her hardest hue to hold (innocence passes fast with life, no matter how hard we try to hold on to it). Her early leaf's a flower; but only so an hour (again with the quick passing of time for life.) The leaf subsides to leaf. So Eden sank to grief (death at the end of someone's life and the mourning that comes with it, if only a second to the hour of life), so dawn goes down to day (mourning is over, and the days continue after that someone passes and everyone has mourned). Nothing gold can stay (life is valuable, like gold, and vanishes much in the same way).
