Battle of Badung Strait
(February 19-20, 1942)

The invasion of Bali was carried out by a relatively small advance force of Japanese warships covering a pair of transports. The transports successfully disgorged their troops in Sanur Roads, but were attacked during the day by Allied airpower. One of the transports was severely damaged. The Japanese withdrew the majority of their force to the north, detailing one pair of destroyers (Michishio and Arashio) to escort the cripple, and another pair (Oshio and Asashio) to bring up the rear with the undamaged Maru. Just as this latter pair was getting underway, the first of two Allied squadrons charged with breaking up the landings appeared. Composed of a Dutch and Australian light cruiser and three destroyers, it heavily outgunned the Japanese force. However, the Japanese bravely gave battle, first driving off the light cruisers through the channel northward, and then turning to attack the Allied destroyers. A successful torpedo attack resulted in the sinking of one of the Allied destroyers, which then shortly drew off to the south.

Shortly afterwards, however, the second Allied squadron of four U.S. destroyers and a Dutch light cruiser came up the Strait from the south as well. Oshio and Asashio again returned to defend the damaged transport against a second superior enemy force. In short order they had attacked the U.S. destroyers so fiercely as to force them to withdraw through the Strait to the north, leaving only the Dutch light cruiser Tromp to be dealt with. This they quickly did, hitting the cruiser eleven times in the superstructure in rapid succession. She, too, fled.

The final act was played out as some of the Allied warships retreating northward ran into Michishio and Arashio. A sharp fight developed, in which Michishio was heavily damaged. However, the Allied ships continued on their way without giving a serious fight.

The final result of this rather confusing action was that two superior Allied squadrons had been manhandled almost singlehandedly by a lone pair of audacious Japanese destroyers. It was a most embarrassing performance by the Allies, who were admittedly heavily fatigued, but who possessed more than enough firepower to deal handily with their Japanese adversaries. This was the first of the impressive night-fighting performances the Japanese Navy would turn in throughout the war.
