Notes
1.
The 1853 expedition was comprised of the Mississippi, Susquehanna, Saratoga,
and Plymouth. The 1854 expedition was made up
of nine vessels (the Plymouth did not accompany the second
voyage).
2.
The three steamships in the squadron were
the Mississippi, Susquehanna, and Powhatan. The Susquehanna
and Powhatan had two 31-foot-diameter paddlewheels,
driven by two “inclined direct-acting
condensing engines.” The Mississippi’s paddlewheels were driven
by “side-level engines.”
3.
All of the wind-driven ships were three-mast,
square-rigged vessels.
4.
During the Japan expedition, crews did not
necessarily achieve full complement.
