A battalion of the 48th Infantry Division of the Imperial Japanese Army landed on Bali on 18 February 1942. Dutch Admiral Karel Doorman's naval forces were scattered around Indonesia, but the invasion of Bali could not be ignored – it would give the Japanese an airbase within range of the ABDA naval base at Surabaya – so he sent in all available ships. The short notice gave no time to concentrate his ships; accordingly, several Allied forces were to attack the Japanese.
Battle
The first Allied vessels to engage were the submarines and. Both attacked the Japanese convoy on 18 February, but did no damage and were driven off by depth charges from Japanese destroyers. Later that day, 20 planes of the United States Army Air Forces attacked the convoy but succeeded only in damaging the transportSagami Maru. The Japanese were aware that their invasion convoy was likely to be attacked again, so they retreated north as soon as possible. The cruiser and the destroyers, and were well away and took no part in the action. The last ships to leave were the two modes of transport, each escorted by two destroyers. Sasago Maru was escorted by and ; the heavily damaged Sagami Maru was escorted by and. The first Allied group—consisting of the cruisers and and the destroyers,, and —sighted the Japanese in Badung Strait at about 22:00 and opened fire at 22:25 on 19 February. No damage was done in this exchange of fire, and the two Dutch cruisers continued through the strait to the northeast, to give the destroyers a free hand to engage with torpedoes. Then Piet Hein, Pope and John D. Ford came into range. At 22:40, a Long Lance torpedo from Asashio hit Piet Hein, sinking the Dutch destroyer immediately. Asashio and Oshio then exchanged gunfire with Pope and John D. Ford, forcing the two American destroyers to retire to the southeast instead of following the cruisers to the northeast. In the darkness, Asashio and Oshio mistook each other for enemy ships and fired on each other for several minutes, without any damage. About three hours later, the second group of ABDA ships—the cruiser and the destroyers,,, and —reached Badung Strait. At 01:36, Stewart, Pillsbury and Parrott launched torpedoes but did no damage. Then Oshio and Asashio sortied again and there was another exchange of gunfire. Tromp was hit by eleven shells from Asashio, severely damaging her and hit both Japanese destroyers, killing four men on Asashio and seven on Oshio. Tromp later had to return to Australia for repairs. Arashio and Michishio had been ordered by Admiral Kubo to turn back, and at about 02:20 they joined the battle. Michishio was hit by shells from Pillsbury, John D. Edwards and Tromp, killing 13 of her crew and wounding 83. She lost speed and had to be towed after the battle. During these exchanges, Stewart was also damaged topside and one shell hit opened seams below the waterline aft and flooded the steering engine room. Both groups of ships turned away, and the engagement was over.
Aftermath
The third ABDA group—seven torpedo boats—arrived in Badung Strait at about 06:00 but did not encounter any Japanese ships. The battle was a significant victory for the Japanese. Lieutenant Commander Gorō Yoshii of Asashio and Commander Kiyoshi Kikkawa of Oshio had shown great bravery and skill. They had driven off a much larger Allied force, sunk the destroyer Piet Hein, damaged the destroyer Stewart and severely damaged the cruiser Tromp. Meanwhile, the Japanese had sustained little damage themselves, and had protected their transport ships. Bali's garrison of 600 Indonesian militia offered no resistance to the Japanese, and its airfield was captured intact. The Japanese continued their conquest of the Dutch East Indies with the capture of Timor from 20–23 February. The ABDA forces engaged at Badung Strait were decisively defeated in the Battle of the Java Sea on 1 March 1942, in which the Dutch cruisers Java and De Ruyter were sunk and Admiral Doorman was killed. Tromp evaded this fate, for she was withdrawn to Australia to repair damage suffered at Badung Strait. The US destroyer Stewart was sufficiently damaged that she had to be placed in dry-dock for repairs in Soerabaia, where she was scuttled to avoid capture by the rapidly advancing Japanese. She was raised, repaired and put into Japanese service a year later as the patrol vesselP-102.
