The remainder of the Kondo's force supports carrier attacks on Java and departs Staring Bay following the Striking Force, CruDiv 8, DesRon 1 and six tankers.

27 February 1942:
Seaplane tender USS LANGLEY (AV-3) and her escorts, the old flush deck, four-stackers WHIPPLE (DD-217) and EDSALL (DD-219) are attacked by 16 twin-engined Mitsubishi GM41 "Betty" bombers of the Takao Kokutai based at Denpasar, Bali, six Mitsubishi A6M fighters and one Mitsubishi C5M Type 98 ("Babs") reconnaissance aircraft of the 3rd Kokutai and nine A6Ms and one Type 98 from the Tainan Kokutai. They damage LANGLEY so severely that she is abandoned. EDSALL picks up 177 survivors and WHIPPLE 308. The next day, the destroyers rendezvous with USS PECOS (AO-6) off Christmas Island. EDSALL begins transferring LANGLEY's survivors to PECOS, but more bombers arrive and force the EDSALL to depart.

1 March 1942:
Indian Ocean. In the morning, Lt Joshua J. Nix's EDSALL completes transferring LANGLEY's survivors to PECOS, then heads towards Tjilatjap. [2]

At 0700, per KdB signal order no. 46, TONE and CHIKUMA each launch one Type 0 Aichi E13A1 Jake recon floatplane to search the waters around Christmas Island and to the west. The planes find merchant shipping, but no warships.

CHIKUMA's floatplane locates an Allied ship. At 1130, CruDiv 8 and destroyers KASUMI and SHIRANUHI intercept Dutch freighter MODJOKERTO attempting to escape from Tjilatjap to Australia. CHIKUMA opens fire and sinks MODJOKERTO before noon at 12-40S, 106-40E.

At about 1400, the floatplanes return to the ships.

250 miles SSE of Christmas Island. At 1550 (local), the Mobile Force is steaming at 16 knots at 14-25S, 106-50E, when one of AKAGI’s combat air patrol fighters sights a "MARBLEHEAD-class" light cruiser (actually, EDSALL) steaming behind the force about 30 kilometers away.

At 1552, Vice Admiral Nagumo orders BatDiv 3/2 and CruDiv 8 to intercept the "cruiser" and destroy it. Vice Admiral Mikawa leads the chase from HIEI, flanked by heavy cruisers CHIKUMA (port) and TONE (starboard), leading KIRISHIMA.

At 1602, EDSALL is sighted 16 miles away, heading north. At 1603, CHIKUMA opens fire with her 8-inch guns at extremely long range. All her shots miss. EDSALL, damaged earlier by one of her depth charges, lays down a smokescreen and begins evasive maneuvers.

At 1616, HIEI opens fire with her forward 14-inch guns at a range of 27,900 yards, straddling the target, but not hitting it. After 1619, she launches all her floatplanes.

At 1620, HIEI signals: "All forces, charge!" The target is soon identified as a destroyer by HIEI and CHIKUMA. At 1639, Admiral Mikawa orders flank speed. At 1655, HIEI and the heavy cruisers check fire without having scored a single direct hit. At 1800, CHIKUMA ceases firing when she enters a rain squall.

CruDiv 8 expends 844 8-inch and 62 5-inch rounds at the old destroyer. Finally, at 1835, TONE scores a direct hit on EDSALL.

EDSALL is attacked by twenty-six D3A "Val" dive bombers from carriers HIRYU, KAGA and SORYU. They hit EDSALL with 550-lb bombs and set her afire. She goes dead in the water. [3]

CHIKUMA moves in and destroys stationary EDSALL with her secondary armament. At 1900, the battered old "four piper"sinks by the stern at 13-45S, 106-47E. CHIKIMA picks up five or more survivors. [4]

About 1600, the carrier Striking Force is located by Consolidated PBY "Catalina" flying boat QL-A of 413 Squadron, Royal Canadian Air Force (RCAF) flown by squadron leader Squadron Leader Leonard Birchall, out of Koggala. Birchall manages to radio in the position of the Japanese fleet and alert Colombo about the impending attack before his Catalina is shot down by six A6M2 Zeke fighters from carrier HIRYU. Birchall is one of the six survivors of the crew of nine picked up by ISOKAZE.

5 April 1942, Easter Sunday: The Attack on the British naval base at Colombo:
At 0730, 127 aircraft from the Striking Force (53 Nakajima B5N2 “Kate” dive-bombers [18 from SORYU, 18 from HIRYU and 17 from AKAGI], 38 Aichi D3A1 “Val” torpedo-bombers [19 each from SHOKAKU and ZUIKAKU] and 36 Mitsubishi A6M “Zeke” fighters (9 each from AKAGI, SORYU, HIRYU and ZUIKAKU) of the "Kido Butai's" aircraft, led by Cdr (later Captain) Fuchida Mitsuo (of Pearl Harbor), attack the British naval base at Colombo, Ceylon (now Sri Lanka).

The planes damage the base's facilities, destroy at least 26 aircraft (6 Fairey "Swordfish", 4 Fairey "Fulmars" and at least 16 Hawker "Hurricanes") and sink destroyer HMS TENEDOS undergoing refit, armed merchant cruiser HMS HECTOR and 5834-ton Norwegian tanker SOLI. The planes also damage submarine tender HMS LUCIA, 5,943-ton British freighter BENLEDI and 5,950-ton British freighter CLAN MUROCH. 81 civilians and 56 RN personnel are killed at Colombo (TENEDOS 33, HECTOR 4, LUCIA 2, FAA aircrew and ground crew 12.

A Kawanishi E7K "Alf" three-seat float biplane from cruiser TONE finds Vice Admiral (later Admiral of the Fleet Sir) James Somerville's (former CO of HMS NORFOLK) British Eastern Fleet's cruisers HMS CORNWALL and HMS DORSETSHIRE at sea - without air cover. Between 1338-1400, 53 D3A Val dive-bombers (17 from AKAGI, 18 from HIRYU and 18 from SORYU, led by LtCdr Egusa Takashige (SORYU’s Air Group Commander), sink both ships. 424 RN personnel are killed (DORSETSHIRE 234, CORNWALL 190). After the attack, the Striking Force withdraws to the SE and searches unsuccessfully for the rest of Somerville's fleet.

Meanwhile, during the afternoon aircraft from RYUJO sink the 5,082-ton British cargo vessel HARPASA and damage two other merchantmen, the 7,823-ton British ship DARDANUS and 4,839-ton US-built Greek ship POINT CLEAR. At 2030, Ozawa's Mobile Force separates into three groups to attack merchant shipping in the Bay of Bengal. CruDiv 7/1's KUMANO and SUZUYA, under Rear Admiral Kurita, form the Northern Group with destroyer SHIRAKUMO. Carrier RYUJO, CHOKAI, SubRon 5's light cruiser YURA, Des Div 20's YUGIRI and ASAGIRI form the Center Group under Admiral Ozawa. MOGAMI, MIKUMA and destroyer AMAGIRI form the Southern Group.

Ozawa's cruisers also sink 6,622-ton British freighter INDORA and Captain J. H. Gregory’s British India Line’s 4,921-ton cargo ship SILKSWORTH. About 50 of SILKSWORTH's mostly Chinese crewmen survive.

Temporarily detached from the rest of Ozawa’s Center Group, YURA and YUGIRI sink 1,279-ton Dutch merchant BATAVIA en route from Calcutta to Karachi. YURA and YUGIRI also sink 1,279-ton Dutch freighter BANJOEWANGI and 3,471-ton British steamer TAKSANG.

The rest of the Center Group, RYUJO, CHOKAI and ASAGIRI, sink five ships:
5,491-ton American freighter BIENVILLE is bombed by RYUJO's aircraft. She is finished off by gunfire from CHOKAI, and reportedly also from RYUJO, and then by a torpedo from CHOKAI.
6,426-ton British cargo ship GANGES is attacked by one of CHOKAI’s floatplanes and two of RYUJO’s aircraft, and is then sunk by gunfire from the surface ships, including gunfire from RYUJO.

Authors' Notes:
[1] Mt. Niitaka, located in Formosa (now Taiwan), was then the highest point in the Japanese Empire.

[2] On 1 March 1942, planes from carriers AKAGI, KAGA, HIRYU and SORYU launched strikes that sank PECOS. WHIPPLE rescued 232 survivors and took them to safety in Australia.

[3] Don Kehn, Jr's book "A Blue Sea of Blood" cites Japanese records that indicate SORYU's Vals were not led by LtCdr (Captain, posthumously) Egusa Takashige as alleged in many other works.

[4] Different numbers have been published for the survivors from USS EDSALL. BatDiv 3/2's combat diary suggests seven sailors were rescued.

[5] Postwar in Hong Kong, Sakonjo is executed as a war criminal by the British.
