At 10:00, an aircraft from ''Tone'' searching the southwest area spotted and began shadowing ''Dorsetshire''<nowiki>'</nowiki>s force; the aircraft reported that the cruiser was heading southwest and making 24 knots.<ref name="Boyd_373"/> The cruisers reported the shadower, but had no means to drive it off.<ref name="Roskill_27"/> Nagumo increased speed from 24 to 28 knots upon receiving the sighting. Carrier Division 5's reserve strike force was ordered rearmed with anti-ship torpedoes, replacing the high explosive bombs intended for a second strike on Colombo. The rearming encountered delays, and the strike was carried out by Carrier Division 2 instead; ''Soryu'' and ''Hiryu'' began launching dive bombers at 11:45.<ref name="Boyd_373"/> Force A radar detected the air strike on ''Dorsetshire''<nowiki>'</nowiki>s force at 13:44, putting the aircraft {{convert|34|mi|km}} to the northeast.<ref name="Boyd_372"/> ''Cornwall'' and ''Dorsetshire'' were sunk at 1400;<ref name="Boyd_374">Boyd, p. 374</ref> ultimately 424 officers and crew were lost.<ref name="Roskill_27"/>

The Japanese missed an opportunity to find Force A after sinking the cruisers. The aircraft shadowing the cruisers flew another {{convert|50|mi|km}} along the cruisers' course before returning to ''Tone''. It would have detected Force A if it had flown southwest another ten minutes.<ref name="Boyd_374"/>

Nagumo recovered the strike against the cruisers at 14:45.<ref name="Boyd_374"/>
