PARTIAL HISTORY

On August 28, 1943 CH-26 and CH-34 depart Palau as escorts for "Wewak No. 7" convoy bound for Wewak. The convoy also includes transports Hankow Maru, Aden Maru, Nagato Maru and Shinyu Maru.

On September 2, 1943 the convoy anchors at 1:45am in Wewak Harbor and Boram Bay off Wewak. While anchored, a barrage balloon was tethered above the vessel to protect it from low level attack. That morning, B-25D Mitchell from the 38th Bombardment Group escorted by P-38 Lightnings from the 8th Fighter Group, 80th Fighter Squadron. During the attack several of the vessels are sunk or damaged.

PARTIAL HISTORY

Sinking History
On March 25, 1945 east of Khota Andaman. At 1030, the convoy is intercepted by Captain (later Admiral Sir) Manley L. Power's 26th Destroyer Flotilla consisting of destroyers HMS SAUMAREZ, HMS VIRAGO, HMS VIGILANT and HMS VOLAGE. At 1059, the destroyers open fire on the convoy with gunfire and launch eight torpedoes, all of which miss.

The undamaged convoy makes for the southwest. At 11:29am, Captain Powers radios for air support. Two RAF Consolidated B-24 “Liberator”bombers soon arrive and in a low-level bombing attack sink TESHIO MARU taking down 11 crewmen, but one B-24 is caught in the blast of its own bombs and crashes into the sea.

At 1150, the 26th Destroyer Flotilla renews its attack on the convoy. HMS VOLAGE sinks RISUI MARU. HMS SAUMAREZ rescues the B-24's crew. At 1230, HMS VIRAGO and HMA VIGILANT open fire at long range on CH-34 and CH-63. HMS VIGILANT closes and fires eight torpedoes at the subchasers, one of which hits and sinks CH-63.

CH-34 fights back against HMS VIRAGO and HMS VIGILANT and manages to score a hit on HMS VIGILANT, but at 1630, CH-34 goes down under the guns of the British destroyers at 10-38N, 94-42E.

Officially removed from the Japanese Navy list on on August 10, 1945.
