The definite losses for the 18th are in, some of which were scuttled as they were too damaged to escape Java anyway. 5 Cl are lost: Java, Sumatra, Tromp (scuttled), Danea and Dragon (scuttled). 6 DD went down as well, Barker and Bulmer for the Americans, Evertsen and Van Ghent for the Dutch (both scuttled, the British Stronghold and finally Vedetta (Aus).
Orders for the 19th were mainly orders to break out, heavy air attacks on the Batavian port were expected and lounging around on the open sea wasn't an option either. Ships would mainly flee in the direction of Soerabaja and ports along the way for those with less fuel and speed, but Electra and Houston would be trying to use the Oosthaven straight. A night of extremely confused fighting followed, no surprise as there were about 10 Allied TF running around. It's all text format because a map would become unreadable. For those who need only the highlight, see the picture
CV Hiryu - KB is trying to make it's way back into the Java sea, but is spooked by a single DD, the HMS Electra. Twice KB meets her in the waters around Merak, and twice she retreats away from her. When she finally breaks through a gauntlet of subs has formed, and HMS Truant gets lucky.
HMS Electra - This lucky ship deserves her own entry, twice she was attacked by subs, twice she evaded the torpedoes. Twice she also ran into KB, the first time a long range encounter with KB turning away, the second time a close encounter in which some shells were exchanged.
CL Marblehead - Damage turned out to be moderate on the Marblehead and she tried to make her way to Batavia, which didn't happen without problems. She briefly met the invasion group, but combat was declined by both sides. A couple of hours later she met I-162 who put a first torp in her, I-158 finished her off with another 2.
CL Durban, DD Banckert, DD Witte de With - These ships made port in Semarang to refuel, but were attacked by bombers from KB. Durban was sunk, heavy damage was done to the 2 DD.
Porter and Stewart - These 2 undamaged destroyers tried to run away together, but stumbled on the invasion forces at Kalidjati, bravely they charged, but Porter got torpedoed and sank, Stewart, also damaged, fled into the night only to be picked off by a sub later.
Dutch PT-boats - These did the first attack of the night at Kalidjati (no rest for the Japanese here), they managed to sink an xAP, but one PT was shot apart by BB Nagato in return.
Air attacks - An air attack on the port of Batavia hit the two CM hidden there all along the Island air bases are swept, resulting in high losses to the Dutch fighters.
