Independence Seaport Museum

This guide to Independence Seaport Museum in Philadelphia follows the cruiser Olympia's October 1921 Atlantic crossing, carrying the casket of the World War One Unknown Soldier home from Le Havre. Forty-one Marines keep a nonstop watch over the casket as the tail of two hurricanes batters the ship with twenty-foot seas breaking over the pilot house. One Marine loses his boots to the surge partway through the voyage and keeps his post barefoot anyway, lashed to a stanchion to keep from being swept overboard.
