"Tinosa" reported a seven-ship convoy on the morning of 3 May and "Parche" headed north at full speed to intercept. An hour after midnight "Parche" was in position and scored three torpedo hits on the leading ship and two hits on the second freighter, sinking both. "Parche" scored two hits on the third freighter, which settled by the stern and began to list to port. Post-war records credited the trio of submarines with five sinkings and 30,542 tons, "Parche" getting credit for "Taiyoku Maru" and "Shoryu Maru". "Parche" returned to Midway 23 May 1944, after making a thorough photo reconnaissance of military installations on the island of Ishi Gaki Jima.
