One form of irony is the contrast between expectations and what actually happens, what is ironic about balboa's first glimpse of the pacific ocean? why does the author present the crowning moment of balboa's achievement this way?

Balboa's first glimpse of Pacific ocean is ironic because he discovered Pacific Ocean and claimed the ocean but his ambition and achievement posed a threat to Pedro Arias Davila, The Spanish Governor of Darien, who falsely accused him of treason and got him executed in early 1519.
