sights a convoy of four transports escorted by two destroyers.

two torpedoes at an anchored cargo ship. HAYO MARU blows up, splits in two and
sinks at 16-37N, 120-17E. All troops of the 48th Division had already been put ashore,
but the 4th Field Hospital's equipment is lost and two crewmen are KIA.
Destroyers close the submarine, and Chapple puts S-38 on the shallow 80
foot (24 m) bottom. S-38 lay doggo as depth charges are dropped, but none close.
From 0804 to 0930, S-38 ran silent, using evasive maneuvers s. At 0930, the
submarine runs aground on the bottom. She remains there most of the day.
Overhead, destroyers and small boats continue to search, but without success. At
2130, S-38 tries to clear by backing, but her port propeller is damaged. Nevertheless,
by 2201, she is free and underway out of the area.
