 The other ships were the "Banryu" and the "Takao".Nicol had been selected for the main attack on the "Kaiten" because he was a native of Bordeaux, and happened to know well about the characteristics and construction of the revolutionary warship "Kotetsu", built in the same city.To create surprise, the "Kaiten" entered Miyako harbour with an American flag, and the "Banryu" with a Russian one.
