Near the mouth of the Argolic Gulf a "Staffel" of nine "Luftwaffe" Junkers Ju 87 "Stuka" dive-bombers from "Sturzkampfgeschwader 77" attacked the convoy at either 06:45 or 07:15. "Slamat" was hit, set afire and began to abandon ship. "Calcutta" ordered "Diamond" to go alongside "Slamat" to rescue survivors while the rest of the convoy continued to try to reach Souda Bay in Crete. At 08:15 "Diamond" reported that she was still rescuing survivors and still under air attack. By then three destroyers had reinforced the convoy so "Calcutta" sent one of them, , to assist "Diamond". "Slamat" was afire from stem to stern when "Diamond" fired a torpedo that sank her in a "coup de grâce". "Diamond" reported at 09:25 that she had rescued most of the survivors and was proceeding to Souda Bay. An hour later "Wryneck" signalled a request for aircraft cover.
