Authors' Notes:
[1] The inclusion of CH-24 in this convoy is not corroborated by that vessel's TROM. It could possibly be CH-22 shown on patrol at this time.

[2] The minefield was laid by LtCdr (later Rear Admiral-Ret) Creed C. Burlingame's (USNA 27) USS SILVERSIDES (SS-236) on 4 June 1943. W-28 was probably repaired at Rabaul and later in Japan.

[3] For his actions in the Luzon Strait that night, Ramage was awarded the Medal of Honor.

[4] Both USS PARCHE and USS STEELHEAD received 1/2 credit for sinking YOSHINO MARU.
