Allies got a great sequence of attacks, with the Swordfish and Vildebeest torpedo bombers coming in the 5th and 6th waves, after the small CAP from the carriers had recovered. He also must have gotten some good intel on the landings, as Batavia now has a small force defending, and the troops have moved to Djokjakarta, Madieon, and Soerabaja.
Troops unload at Semarang in good order; 5th Div at 458 AV with a few remnant support elements to unload tomorrow.
