| Footnote : | I-36 launched 4 kaitens, piloted by Lt(jg) Yagi and PO2C Abe, Ebihara and Matsuda, against a convoy, and later heard four detonations. Two kaitens failed as the release gear was faulty. - USS "Ringness", escorting a convoy of landing vessels, observed two kaitens, one of which was sunk while the other detonated. Further detonations were probably caused by depth charges. |
