then circle around to the south and try to get behind the Japanese escorts at 21:00. The American destroyers, low on fuel and out of torpedoes, independently decided to return to Surabaya at that same time. As Doorman was turning his ships north at 21:25, Jupiter struck a Dutch mine and lost all power before sinking. During this time, Takagi was aware of Doorman's movements as one of Jintsūs floatplanes was dropping flares to track the Allied ships. At 21:20 Nakas floatplane relieved it, but it lost contact with Takagi at 22:00 which left both sides searching blindly. At 23:02 Nachis lookouts spotted the Allied cruisers and the sisters manoeuvred to deliver a torpedo attack.

The Allies believed that Sunda Strait was free of enemy vessels, but the Japanese Western Invasion Force had assembled at Bantam Bay on the northwestern tip of Java without their knowledge. The cruisers were heading west when they were spotted at 22:39 by the destroyer on patrol east of the bay at a range of . After reporting to Rear Admiral Kenzaburo Hara, commander of the escort force, the destroyer trailed the Allied ships. Hara's flagship, the light cruiser , saw them at 22:48 at a range of ; Hara concluded that the silhouettes were enemy cruisers at 22:59 and intended to use Natori as bait to lure Perth and Houston away from the transports. At 23:06 lookouts on Perth sighted an unidentified ship and challenged it, expecting to see one of the Australian
