ルバング島
On 7 December 1941, "I-124" laid 39 Type 88 Mark 1 mines off Manila Bay in the Philippines; one of the mines sank the 1,976-ton Panamanian-flagged cargo ship "Daylite" on 10 January 1942. "I-124" then proceeded to an area southwest of Lubang Island to provide weather reports and to stand by to rescue Japanese aircrews downed in air strikes on Manila launched from Formosa after hostilities began.
