To regroup and refocus on generals -- I would like to second Yamashita for not only his conquest of Singapore but also for his defense of the Japanese position in the Phillipines. Despite arriving on the scene less than a month before the US invasion to retake the Phillipines and fighting against an overwhelming US superiority (troops, air support, supply, navy and very importantly local population support {the Japanese by this time in the war were regarded by the local population as brutal occuppiers}) Yamashita army assumed a defensive posture and managed to tie up a strong US army for months. When the war finally ended about half his original force managed to march out of their positions and go home. This is in sharp constrast to McArthur who had years to prepare for a similar strategic situation (with the exception that the US was never as unpopular with the Fillipinos as the Japanese) and managed to get stuck in Bataan without adequate supplies or a plan and then got defeated by second line Japanese troops. The fact that Yamashita was convicted or war crimes and executed now is more documentation of the lack of adequate judicial processes/evidence in the trials than it is an indictment of his behavior or responsibility (although the crimes themselves were clearly committed).
As a general, he was superb in both offense and defense.
Just checking that. Not very impressive as it seems he just had all his men slaughtered to the last man and the casualties inflicted on the americans were pretty minimal in comparison. He did hold out a long time but at a ridiculous cost.
