Caesar's invasion fleet approaches the coast of Kent.

The crew is afraid to leave the ship because the British chariotry is guarding the cliffs.

So the eagle bearer leaps off the ship and starts running toward the Britons, daring his comrades to protect their Eagle.*

* The anecdote was described by Caesar in the "Gallic War".
Seriously, though, I was impressed by how sea worthy the ship is. It careens slightly, but even with an undulating tide remains shipshape. I took it a few feet out, gave it a push with the current, and watched it sail for shore, then ride the tide back and forth until it beached.
Or maybe the disturbingly large quantity of dead, floating fish in Creve Coeur lake terrified the crew enough to keep their mass centered... seriously though it was disgusting.
