"Parche" sighted a convoy 29 July and, cooperating with "Steelhead", closed in, sinking 4,471 ton cargo ship "Manko Maru" and 10,238-ton tanker "Koei Maru". During this night surface action "Parche" barely avoided being rammed by one ship. "Parche" collaborated with "Steelhead" in sinking an 8,990 ton transport, the Yoshino Maru (originally the Kleist, built in Danzig, 1906 for North German LLoyd, surrendered to the British in 1919, and acquired by the Nippon Yusen Kaisha in 1922.) "Steelhead" sank two other ships, a transport and a cargo vessel. Another tanker and a cargo ship were damaged. For this action "Parche" received the Presidential Unit Citation and her commander, Ramage, received the Medal of Honor. On 1 August the sub departed for Saipan where she moored 5 August, arriving Pearl Harbor 16 August.
