While walking the shore
At dusk one day
I saw a mist
of silver spray
Two creatures glided
through churning foam
to splash and play
before the gloam
As silent as death
mysterious as night
slipping through
the fading light
I watched them as
they passed from sight
a host of dolphins
in the pale moonlight

I know that was super random, but I just saw your profile pic and thought of dolphins lol. And sorry it took so long. I hope this helps. Comment when you get your grade! ♥
The Vietcong set up checkpoints around the nation, so that would've definitely been a literal and figurative roadblock to any refugees. Hope this helped.
