echelon with KASHII, KINKA and TAKATSU MARUs. Despite the added defenses of the
Army’s 68th Specially Established Machine Cannon Unit’s 12 deck-mounted 25mm
guns, the aircraft strafe, shoot up, and destroy all of KASHII MARU’s loading
tackle and landing boats. TAKATSU and KINKA MARUs take minor hits to their
engines and deck cargo. Light bombs breach their hulls, but the seas are so calm
that crews are able to control the flooding.
The planes also damage kaibokan SHIMUSHU and OKINAWA. In the evening, the
convoy arrives at Ormoc Bay. The crews plan to unload everything that night, but
cannot get heavy equipment and supplies ashore because of damaged gear and
boats. Smaller sampans had been washed ashore by the typhoon just one day
earlier. Only five of 50 Ormoc Daihatsu landing craft remain in service.

only one battalion lands anything as heavy as its machine guns. The division’s
transportation regiment can only get its staff ashore.

Independent Mortar Battalion.

leave the anchorage to return to Manila. Kaibokan take up stations on the
transport column; one ahead, one astern and one on each flank. The destroyers
remain to port.
N of Cebu. The convoy is attacked by P-38s and B-25s from from Morotai.

B-25J’s of the 38th Bomb Group. KASHII MARU is strafed and hit by bombs at least five times. At about 1230, she explodes and
sinks at 10-58N, 124-35E. An uknown number of survivors are rescued by destroyers from convoy TA Go No. 3, en route to Ormoc Bay.
 Sources vary as to KASHII MARU’s date of completion. A
well-respected Japanese source gives the date as 30 June 1936; however, this
conflicts with contemporary newspaper reports about her maiden voyage in early
 Sources also vary as to KASHII MARU’s gross registered tonnage.
Lloyd’s Register and some Japanese sources claim it was 6,825-tons, while some
respected Japanese and American sources say 8,407-tons.
 Ships' landing positions: ASAKASAN MARU was the reference ship,
positioned 3.700 meters 60 degrees from Singora lighthouse. In a line following
140 degrees from ASAKAN MARU at distances of 700 meters each are SASAKO, KYUSHU,
AOBASAN, SADO and NAMINOUE MARUs. 700 meters 50 degrees from ASAKASAN MARU
starts the outer line beginning with NAKO MARU. In a line following 140 degrees
(parallel from the inner line of ships) from NAKO MARU at distances of each 700
meters are KASHII, ATSUTASAN, SHINSHU and KANSAI MARUs.
 This early in the Pacific War (Dec '41), large ship repair facilities
available to the Japanese in SE Asia were limited to Indochina, later Hong Kong
Kong and even later, Singapore, but no data have been found as to when and where
KASHII MARU actually underwent repairs.
