Factual error: After being under bombardment for several days, don't you think it was polite of the Japanese to shave and put on clean uniforms for the invasion?
Factual error: One does not simply walk (or run) onto or off a U.S. Navy ship. Every individual coming aboard stops at the head of the brow (gangplank to civilians), faces the ensign (flag) at the stern and salutes, then turns to face the officer of the deck (OOD), salutes again, and says, "Request permission to come aboard, sir." The OOD returns the salute and says, "Permission granted," whereupon the individual steps off the brow onto the ship. A similar procedure is used when leaving the ship, with the individual requesting permission to go ashore.
