Action of 11 January 1944

The Action of 11 January 1944 was a minor naval action that resulted in the sinking of the light cruiser JAPANESE CRUISER Kuma of the Imperial Japanese Navy by the British Royal Navy submarine HMS Tally-Ho (P317). Kuma was being escorted by the destroyer JAPANESE DESTROYER Uranami about 10 nmi north-west of Penang, Malaya.

Tally-Ho was patrolling from her base at Trincomalee, Ceylon searching for Japanese vessels and on 9 January, sighted the Japanese light cruiser Kuma off Penang. Kuma was on anti-submarine warfare exercises. She was flanked by destroyers and Tally-Ho could not get within range. She was able to plot the Japanese's route in and out of Penang and to take up a suitable position to intercept the cruiser.

On the morning of 11 January, Bennington spotted a Mitsubishi F1M2 Pete floatplane flying westwards along the route which the cruiser that had been sighted on 9 January was to be expected. It was felt that this heralded the approach of the cruiser. Just before 09:00, the Officer of the Watch sighted the masts of the cruiser on the port bow. Kuma had a destroyer—Uranami—as an escort. Whilst 10 nmi north west of Penang at midday Bennington fired a seven-torpedo salvo from 1900 yd. Kumas's lookouts soon spotted the torpedoes' wakes, and Captain Sugino shifted his rudder hard over. Kuma was hit starboard aft by two torpedoes. Bennington decided to head toward the shallows along the shore. The destroyer Uranami counter attacked with 18 depth charges, but all missed the submarine. A fire raged on board the Kuma and she soon began to sink by the stern. As she sank her own depth-charges detonated. Uranami then picked up the survivors, including Captain Sugino, but 138 crewmen were lost.

After the success, Bennington managed to slip away and returned to Trincomalee.
