I remember as a child being thrilled by the recitation of this stanza of Whitman's poem, "Song for all Seas, all Ships," on a re-run episode of "Victory at Sea."
Flaunt out O sea your separate flags of nations!
Flaunt out visible as ever the various ship-signals!
But do you reserve especially for yourself and for the soul of man
one flag above all the rest,
A spiritual woven signal for all nations, emblem of man elate above death,
Token of all brave captains and all intrepid sailors and mates,
And all that went down doing their duty,
Reminiscent of them, twined from all intrepid captains young or old,
A pennant universal, subtly waving all time, o'er all brave sailors,
All seas, all ships.
