"Among the items presented to the Japanese were a white flag and a letter from Perry. The letter attempted to intimidate Japanese officials by explaining that in the event the Japanese elected war rather than negotiation, they could use the white flag to sue for peace, since victory would naturally belong to the Americans"Matthew Calbraith Perry: antebellum sailor and diplomat by John H.
