context_page_description: Convoy Hi-81 was the designation for a formation of Japanese transports that carried soldiers bound for Singapore and the Philippines during World War II. The transports were escorted by a large force of surface combatants including the escort carriers Shinyo and Akitsu Maru which were sunk in the Yellow Sea by American submarines. Over the course of a four-day convoy battle in November 1944 nearly 7,000 Japanese were killed in action while the Americans sustained no casualties.
context_section_description: Due to the sinking of four ships and the loss of thousands of men, Admiral Sato stopped the convoy in Raffle's Island anchorage near Shanghai to wait for his escorts to finish their rescue operations. It was not until November 21 that the convoy headed for Mako, which they reached two days later. The Japanese fleet then split in two, one half sailing for Singapore and the other for Luzon. The larger portion, sent to the Philippines, arrived at Manila on December 2, and the remainder arrived in Singapore on December 4.
  Another convoy, MI-27, was also attacked west of Jeju Island by Sunfish and Peto in the night between 17 and 18 November. Sunfish sank two troopships, Edogawa Maru with 2,113 killed, and Seisho Maru with 448 killed. Peto sank Osakasan Maru (142 killed) and Chinkai Maru (39 killed).
