After the fall of Burma, Malaya, Netherlands East Indies (NEI), and the Philippines, all types of Allied aircraft were impressed by the Japanese. Several Curtiss P-40E Warhawks were captured by the IJAAF in the Philippines and Java. Historian Rick DUNN relates:
"The SS Seawitch's cargo of 27 P-40s was supposed to have been dumped in the harbor in Java, but the Japanese may have been quick enough to have recovered them without too much corrosion. Also, three crated, brand-new P-40s were delivered to Cebu by SS Anhui about mid March 42. I assume, but can't verify, if they were then transported to Mindanao. Anyway while I don't know their fate they were potentially available for capture
